The series was produced by Taffy Entertainment, in association with Gamania, Hong Ying Animation, Telegael Teoranta, and Turner Entertainment Networks International Ltd. It premiered on March 1, 2010.
The show was renewed for another season, which began airing on May 7, 2012, on Cartoon Network (Russia and Southeastern Europe), UK, April 30 on Cartoon Network Too, and on Cartoon Network in the United States on June 4, 2012. The series ended its run on July 9, 2012. No channel in Canada has aired the series.
Many years ago in the Hidden Kingdom, animals and humans lived in perfect harmony until an evil trickster named HighRoller arrived and fooled the animals into thinking humans were their enemies. Chaos reigned in the Hidden Kingdom until Commander ApeTrully formed a task force called Big Green to reunite the animals and humans while fighting the forces of High Roller and the Zebra Brothers.
The storyline in a typical episode follows a formula, although the formula varies and several episodes depart from it: Commander ApeTrully goes on a mission to the castle of an animal kingdom to make peace and ask its inhabitants to join Big Green, bringing a gift of gold as a token of goodwill. The animals generally dismiss the gift, and usually capture ApeTrully who calls for help from First Squad. Members of First Squad (usually everyone except Mr. No Hands, who does come along on occasion) deploy by descending through a maze of tubes and landing on turtles fitted with tank treads, and then are launched through a tunnel and out over the water. When they arrive where ApeTrully is being held, a battle or contest ensues, during which special talents or abilities of the animals are revealed, often something based on their nature. After the battle or contest, the animals usually concede to First Squad's skills saying through translation by ApeTrully (unless the animal rulers can talk) that they would be honored to join Big Green. After joining, the animals often are assigned a particular duty at Big Green based on their demonstrated skills, which may help solve a problem introduced in a subplot.
Big Green is a peace-making force with goals to restore peace between the humans and animals:
- Commander ApeTrully (voiced by Ian James Corlett) - Commander ApeTrully is the eccentric, well-meaning leader of Big Green. Commander ApeTrully formed Big Green in hopes of restoring friendship between animals and humans. In most episodes, Commander ApeTrully would end up captured by the animals he visits when trying to make peace with them with piles of gold. When in danger, he activates the device on his head to call for First Squad. In "Parrot Castle", he is revealed to be the king of the Monkeys (Monkey King) in disguise as he was the first to see through HighRoller's lies, but keeps it a secret to preserve Big Green's morale (in his words, he does not want humans to know it was a monkey who led them). In "Shark Castle" and "Crab Castle", he would accompany First Squad to the underwater castles when riding in Sammo the Whale in order to make peace with the aquatic animals that way. His name is a joke referring to the fact that he's an ape, truly. In the Chinese dub, he was named Song Chang and there was no explanation saying he was a monkey. Classified on the official website as Hero 001. The only thing he can do is use his monkey skills and use almost an endless supply of gold seen on every episode. In "The Rise of Lin Chung", it is shown that Commander ApeTrully owns a diamond that is larger than his body.
- Woo the Wise (voiced by Adrian Petriw) - Woo the Wise is a human inventor who was the first person to be convinced to join Big Green. At some points, his robe tends to rise up. He wears a fake mustache to make himself look older. A running gag is that he says that he knows what he is doing, yet he really has no idea what to do in his head, thinking "My head is as empty as a balloon!". In a flashback that was seen in "Folk Game Competition II", he was a former classmate of HighRoller. In "Pitched Battle of the Air Force", Woo the Wise invented a special crystal that could assemble animals into one creature, which he did when he tested on four animals allied with Big Green (Elephant King, Peacock Queen, Octopus King, and Scorpion King) and later merged two hens, Snake King, Crocodile King, and Deer King into a Chimeric Dragon to fight High Roller's fake Black Dragon. In "The Bronze Giant", Woo the Wise makes up the blueprints for upgrading Big Green base into a mobile battle station and works on it with the other members of Big Green. Classified on the official website as Hero 003.
The Big Green's elite warriors. Among its members are:
- Mr. No Hands (voiced by Ian James Corlett) - Classified as Hero 020, Mr. No Hands is the military leader of Big Green's First Squad though he does not go on missions as often as his teammates. He is a strict but kindhearted human who is easily irritated by the strong-willed warriors under his charge. The tassel of his hat is capable of spinning like a helicopter, allowing him to fly. The hat itself can shoot dangerous darts at his enemies. He keeps himself in a stockade because he cannot stop tickling himself if his hands were free, though Woo's attempt to cure No Hands leads him to now use the stockade to keep his hands from hitting anything in punching distance. Mr. No Hands was created during Hero 108's Chinese debut, but his ability to fly and his personality as a strict leader were never mentioned there.
- Lin Chung (voiced by Andrew Francis) - Classified as Hero 006, Lin Chung is known by some as the most accomplished, most skilled warrior in all of Big Green. He possesses the legendary Panther Vision, which allows him to see great distances, or to see the world in slow motion while he moves with speed. He wields a staff that can shoot edible bamboo shoots out at enemies. Lin Chung's also has his "Master Stroke" in his arsenal which is devastating to all enemies. This move involves a great leap into the air while spinning his staff. He catches the staff, which propels his full body into a spin, projecting him at his opponent with massive force which was proven in "Rabbit Castle". He has a hobby of drawing and sometimes dropping out of battles just to draw when he finds an inspiration like in the episode "Elephant Castle". In reality, his drawings are awful, but his friends do not tell him that so he will not go into a state of depression up until Woo the Wise made a comment about art not being better than science in "Pitched Battle of the Air Force". His drawing skills got better as the series progressed. He is also an honorable member of the Air Force as he was the only member of First Squad to pass each of the tests required to assist the Air Force. If his First Squad team members cannot find him, they know to look for Lin Chung in the bamboo forest where he mediates, calmly waiting standing on his staff for more bamboo shoots to grow because he is using them for ammunition. Unfortunately, he is often distracted from battle by an intriguing image that he feels he must paint. A gag in "Shark Castle" is that Lin Chung can create great art, but only unintentionally (like being distracted or by accident) which would get him frustrated. In the Chinese dub, he was unofficially credited as PantherEye in the Chinese CGI promos (possibly from the Panther Vision) and there was no explanation of him being an artist. He, ApeTrully and HighRoller are the only characters that had names which were changed. It is later revealed that Lin Chung was trained by Tien Kwan during the events of "The Rise of Lin Chung", gaining the ability to convert chaos energy into harmonious energy while named new leader of First Squad. The Harmonic energy has shown to make Lin Chung seemingly omnipotent, as he was shown to fly, breathe underwater, create air bubbles, generate force fields, use chlorokinesis (control over plants), shoot energy blasts from his body and undo the effects of chaotic energy, all through the power of his harmonic energy. In "The Yeti & Phoenix", it is revealed that every member of Big Green has harmonic energy, but Lin Chung is the only member who can channel and use it. In "Animals Inside", it is revealed that Lin Chung holds the Panther Spirit when he, Mighty Ray, and Mystique Sonia enter the Spirit Cave and are transformed into their inner animals. In this form, he passes himself off as the Panther King in a plot to rescue Commander ApeTrully from HighRoller.
- Jumpy Ghostface (voiced by Brian Drummond) - Classified as Hero 088, Jumpy Ghostface is the King of the Rabbits. He is a talented, straight-ahead fighter who dives headfirst into dangerous battles without flinching an ear. He may look cute as a bunny, but Jumpy is not the sort of animal you would want to meet in combat. He joined Big Green after being defeated in a jump rope battle. His weapon of choice is a jump-rope. He also uses carrots as weapons, either throwing them like shurikens or using them as grenades. He can wrap his ears around his head like a ninja mask. He also has a habit of daydreaming, even in the heat of battle. Whenever someone looks into Jumpy's swirling eyes when he's daydreaming, they end up in Jumpy's daydream. Jumpy Ghostface also has a soft spot for insects and will not let anyone harm them. Jumpy is slowly learning human language by attending classes with Parrot King at Big Green. He has an active imagination and his thought balloons often convey unique solutions to difficult problems mainly interpreted by Lin Chung. In "Ninja Fight," it was shown that Jumpy Ghostface was selected to be successor of the previous Rabbit King instead of Spotter the Rabbit. In "Monster Castle", Twin Masters hit Jumpy Ghostface with his chaotic energies where the side effects caused Jumpy Ghostface to dream up dream versions of Bearstomp, Tri-Puppy (a Cerberus-like monster), and Moosey Ghostface (a moose monster) whenever he slept. Using a special machine built by Woo the Wise and Mr. No Hands, Jumpy was able to dream up a giant version of himself in order to send the dream monsters back to the Dream World. As the chaotic energies in Jumpy wore off, Jumpy then said goodbye to his giant counterpart as it went back into the Dream World. He is also known to always hold a carrot in his mouth like a large cigar in the series.
- Mystique Sonia (voiced by Kelly Sheridan) - Classified as Hero 103, Mystique Sonia is a tough, seasoned warrior. She is usually bickering with Mighty Ray. She can use her long tongue in battle to fight off enemies, using it like a whip and spinning it around to produce winds. Yaksha can also pull out a shard of ice which Mystique Sonia blows on it with her spinning tongue in order to produce strong and cold winds that freeze her opponents. She possesses seeds that grow freshly cooked buns when she spits on them for food. She can also play the flute. She likes flowers, decorations, and other pretty things. While powerful, she is also a total girl. It is not unheard of her for to take down Mighty Ray in a wrestling competition and then decide to redecorate the First Squad Briefing Room. Mystique Sonia is admired by many boy heroes, especially by the soldiers in the Big Green Army. The Sailor Brothers have a terrible crush on her as well. But woe to the one who tells Mystique Sonia he loves her. Since she is cursed with a spell, anyone who tells her he loves her three times in a row turns into a Yaksha. Mystique Sonia has a soft spot in her heart for animals and is very fond of both Elephant and Panda Kings, as well as the Turtle Cannons. Sonia often feeds First Squad by growing magic buns. She has many different kinds of seeds that she throws on the ground. When Mystique Sonia spits on these seeds they instantly grow and provide various powers. Mighty Ray and Mystique Sonia have an interesting relationship. In "Animals Inside", it is revealed that Mystique Sonia holds the Swan Spirit when she, Lin Chung, and Mighty Ray enter the Spirit Cave and are transformed into their inner animals. In this form, she passes herself off as the Swan Queen in a plot to rescue Commander ApeTrully from HighRoller. Mystique Sonia's swan form enables her to produce winds from her wings. In the Chinese CGI promos, there is no explanation showing her ability to stretch her tongue but it does explain that she grew buns.
- Yaksha - Due to a spell cast on Mystique Sonia, anyone who declares their love for her three times turns into a Yaksha. Yaksha is a purple and pink creature which rests upon Mystique Sonia's head like a hat. It is also an extremely flexible and stretchable being shown to turn into various forms to aid Mystique Sonia like an accessory, a dress, and a trampoline. It can even extend its arms to propel Mystique Sonia forward. By putting Yaksha's eyes over her own eyes, Mystique Sonia can see heat and the body heat given of by animals. Curiously, this ability works on chameleons despite the fact that they do not give off heat. Yaksha can also put his arms out like plane wings and if Mystique Sonia does her tongue attack from a short radius as if her tongue were a planes propeller, Mystique Sonia can fly. When Mystique Sonia gets mad at Yaksha for his jealousy as seen in "Scorpion Castle" and "Sheep Castle", he will usually rest on Mighty Ray's head. When Mystique Sonia is not mad at Yaksha, he usually gives her a rose. It is unknown who was the first to fall for Sonia, but in "Liger Castle", he was killed in action as a Yaksha. It was soon replaced by a new Yaksha who was once a Tank Army member and a devoted member of Mystique Sonia's fan club. In "Scorpion Castle", when Yaksha ate 100 buns he transformed into a robot-like Yaksha with Lin Chung for the head, Sonia and Jumpy for the hands, and Mighty Ray and Mr. No Hands for the legs. In the Chinese dub, references of Yaksha and Mystique Sonia's relationship were never mentioned and his voice is completely different from the North American dub.
- Mighty Ray (voiced by Ian James Corlett) - Classified as 025, Mighty Ray is a warrior of First Squad. Mighty Ray was once a member of Mr. No Hands' giant foosball team. They were playing a match, but it was postponed as HighRoller, the Zebra Brothers, Bear Stomp and some of the toughest animal kings attacked the stadium. Mighty Ray defeated the animal kings, but the Zebra Brothers used their ghost lanterns to turn Mighty Ray's eyes to stone. Mr. No Hands took Mighty Ray to a temple where Commander ApeTrully took Mighty Ray to see a giant stone skeleton monkey, who traded his own eyes for Mighty Ray's eyes. He has the power to shoot electrical bolts of energy from his eyeballs. To recharge his eyeballs, Mighty Ray must eat more bananas which he dislikes. The reason Mighty Ray dislikes bananas is because when he first tried out his magical electrical eyeballs, he figured that the more bananas Mighty Ray eats at once, the more powerful his eyes get. But when Mighty Ray tried to defeat HighRoller (for payback on turning his original eyes to stone), Mighty Ray ate too many bananas, which overloaded his eyeballs causing bolts of electricity to fire every where. ApeTrully said Mighty Ray was lucky he didn't go blind. He can also form a giant eyeball and emit sonic waves to confuse his enemy as seen in "Rabbit Castle". His eyeballs are also removable. He is able to change the properties of the lightning by pressing on his left eye which allows him to shoot at single targets or at a whole group. Even though his energy bolts are his main attack, he is quite formidable at close range with his bare hands. He is intensely jealous of Lin Chung being praised as the finest warrior in First Squad and jumps at chances to best him. Mighty Ray also goes by the name of Mr. Comedy when performing all sorts of comedy. Mighty Ray is definitely the burly force of First Squad. More of a doer than a thinker, Mighty Ray takes great pride in being the right guy for any job even if he's actually not. However, his overzealous and sometimes inept nature can occasionally win the day. Mighty Ray enjoys loud burps, farts and bad comedy all of which are usually his own. His eyeballs can also be used as lanterns or thrown like grenades. Sometimes they pop out of his head and slide away, making them very difficult to find. Mighty Ray's signature yell is "I am Mighty Ray! Fear my eyeballs!" Mystique Sonia is the only member of First Squad who knows Mighty Ray is afraid of the dark as seen in "Crocodile Castle". One of the symbols on his eye seems to be "電" or "Diàn", meaning "electricity". In the Chinese dub, he touches his eyeballs to charge them up to shoot instead of eating bananas. In "Animals Inside", it is revealed that Mighty Ray holds the Boar Spirit when he, Lin Chung, and Mystique Sonia enter the Spirit Cave and are transformed into their inner animals. In this form, he passes himself off as the Boar King in a plot to rescue Commander ApeTrully from High Roller. Mighty Ray's boar form involves him eating bananas in order to shoot electric bolts from his tusks.
The Big Green's secondary warriors. They are jealous of First Squad and constantly at odds with them to prove their worth. Among its members are:
- Alpha Girl Latifah (voiced by Tabitha St. Germain) - The brown-skinned Oni-like leader of Big Green's Second Squad with long black hair and sharp claws who serves as a rival to Mr. No-Hands. She wields a spiked club in battle. She is classified as Hero 101.
- Golden Eye Husky (voiced by Brian Drummond) - Golden Eye Husky is the King of the Ligers who became a member of Big Green's Second Squad after joining Big Green. He seems to be a rival to Jumpy Ghostface since they are both animals. He is classified as Hero 093.
- Kowloon (voiced by Ian James Corlett) - A karate warrior. He seems to be a rival to Lin Chung. In Hero 108 online, he wields a staff. Classified as Hero 023. His major role outside of Second Squad was the second-season premiere "The Rise of Lin Chung" serving as Lin Chung's replacement for First Squad, despite not being taken seriously that much. But as soon as he saw Lin Chung in combat, he grew a fond of First Squad and actually has a friendship with them but still goes jealous over their success.
- Hurricane Lee (voiced by Scott McNeil) - A large, gray-skinned, powerfully built member of Big Green's Second Squad and brother of Archer Lee. He wields two axes in battle. It might be possible that he has a rivalry with Mystique Sonia. He doesn't speak until "Second to None". He is classified as Hero 022.
- Archer Lee (voiced by Tabitha St. Germain in Season 1) - The blue-skinned, armored archery member of Big Green's Second Squad and brother of Hurricane Lee. It is possible that he might have a rivalry with Mighty Ray. Archer Lee and Golden Eye Husky are the only characters to be created during Hero 108's Chinese debut. He is classified as Hero 009.
Big Green Air Force
A part of Big Green's army that specializes in air battles. They dress in white and use large jet-shaped firecrackers as jets and giant afros inside their hats as air brakes and parachutes. Among the members are:
- Master Chou (voiced by Brian Drummond) - Leader of Big Green's Air Force. He rides on the same plane as Burly. Classified as Hero 086.
- Rosefinch (voiced by Kelly Sheridan) - Female Member of Big Green's Air Force. Classified as Hero 104.
- Burly (voiced by Ian James Corlett) - The biggest member of Big Green's Air Force. He usually pulls together the planes for a combined attack which makes his eyes bulge out. Classified as Hero 065.
- Mano - The member of Big Green's Air Force with an eyepatch. Classified as Hero 083.
- Air Force Staff - The generic staff members that serve the Air Force.
- Red-Face Kwan (voiced by Eric Bauza) - Classified as Hero 005, he is a human that leads the Infantry of Big Green. He is named Red-Face Kwan because a crab is clamped on his bottom enhancing his anger. When the crab is removed, he makes a funny face as seen in "Lion Castle". He is a direct reference to Guan Yu.
- Sailor Brothers (voiced by Brian Drummond) - Three green-skinned brothers who head up Big Green's Navy. They have a habit of collecting string in order to make their fishing nets and are good ring throwers due to them always throwing life preservers to rescue drowning people. They have a major crush on Mystique Sonia. Classified as Heroes 028, 029 and 030. In "Strongest Punch & Kick," the Sailor Brothers combine with Jumpy Ghostface to form a fighting formation in order to fight the Gorilla-Roo formation.
- Rattle Diva (voiced by Tabitha St. Germain) - A geisha guitarist who loves to play for anyone she comes in contact with and hates those who upstage her during her concerts like when Mighty Ray and Mystique Sonia ruined her concert by getting on stage and performing with her in "Pandaffe Castle". She can also turn her dress into a rocker outlet and play heavy metal songs. She also wears a wig in her geisha appearance, but removes it when she appears in her rocker costume. She plays a pipa.
- Sammo the Whale (voiced by Andrew Francis) - Classified as Hero 044, Sammo is a whale that serves as transportation for Big Green and the Navy when it comes to missions at sea. His cowardice is what had the other whales drive him away causing his tears to flood the planet. Commander ApeTrully convinced him to join Big Green. Woo the Wise invented a device that attaches to Sammo the Whale where the Sailor Brothers ride in its artillery part while the others ride in Sammo's mouth. The episode "Pitched Battle of the Navies" revealed that someone once lit a fire in Sammo which created a soot deposit that partially blocked up his blowhole and majorly hindered his ability to play volleyball. This was cleared out by Lin Chung using one of Mystique Sonia's strength buns.
- Wu Sung (voiced by Eric Bauza) - Wu Sung is the Big Green's dentist. He calls himself a dental warrior due to his dentist tools all being in a sword-like holder. He is the twin brother of the Dog King. He is classified as Hero 014.
- Gardener Ching (voiced by Andrew Francis) - Big Green's gardener. He grows the large Calabash Gourds for the Tank Army's tanks and would often insult anyone in order to get the tears to help grow them as seen in "Chameleon Castle". Gardener Ching appeared in the original Hero: 108 lineup as well where instead of being a gardener, he can shoot laser eyes.
- Origin Man - Origin Man is a caveman who was found frozen in a block of ice with a Tyrannosaurus by Twin Masters. Twin Masters thawed them out and used his chaotic energies on Origin Man and the Tyrannosaurus where he had them attack Big Green. Due to First Squad being more advanced than them, Origin Man and the Tyrannosaurus are defeated. After the Tyrannosaurus "sacrifices" its life to "eliminate" Twin Masters, Origin Man joins up with Big Green (with his designation being Hero 070).
- Lady Green (voiced by Kathleen Barr) - Classified as Hero 102, Lady Green is a female member of Big Green's navy who has never been defeated in battle before.
- Yan Ching - A small aquatic humanoid whose strength makes up for his size. He and his kind were tricked by HighRoller into using their Jellyfish armor and a special elixir into ambushing First Squad in the ocean where their elixirs have shrunk First Squad enabling the Zebra Brothers to capture First Squad and hand them over to High Roller. After First Squad escaped, Yan Ching and his warriors went after them. When Lin Chung defeated Yan Ching, High Roller arrived to finish the job to make up for Yan Ching's "failure." After helping First Squad to subdue Bearstomp, Yan Ching and his kind join up with Big Green (with Yan Ching's designation being Hero 036). In "Demon Heartland", Yan Ching spies on Twin Masters and informs Commander ApeTrully about Twin Master's heart. As First Squad and the Infantry head to the secret island where Twin Masters's heart is, Mystique Sonia had some doubts about Yan Ching. When First Squad, the Infantry, the Sea Elephants, and the Hermit Crabs were trapped in a cave with Twin Master's heart about to detonate, Yan Ching gets Sammo the Whale to help free them.
- Bronze Giant - When Twin Masters began to drain all life in Hidden Kingdom, Lin Chung suddenly was able to draw up the Bronze Giant which has the titular hero classification. Lin Chung was able to form the Bronze Giant by combining with the members of Big Green, the Animal Kings and Queens, and the remaining animals on HighRoller's side. In battle, Bronze Giant used Gorilla King's punches, Jumpy Ghostface's jump-rope attacks, Mystique Sonia's wind attack, Bearstomp's pincher attack, Mighty Ray's eye lightning attack, Cheetah King's speed, Crab King shovel attack, Blowfish King's spine-launching attack, Lizard King's beam attack, Scorpion King's tail attack, and Golden Eye Husky's fire breath. Using the harmonic energies of those who helped to form the Bronze Giant, Lin Chung channels the combined energies and the Bronze Giant uses it to destroy Twin Masters.
- The Tank Army - A part of Big Green's army consisting of metal glove-wearing soldiers that operate large Calabash Tanks. They are led by the Tank Commander (voiced by Andrew Francis) who is classified as Hero 085. They often accompany Commander ApeTrully on some of his missions to defend him in cases of attack.
- Anti-Air Units - A part of Big Green that operates the Anti-Air Cannons in Big Green as seen in "Air Battle". They are led by the Air Defense Captain (voiced by Ian James Corlett). The soldiers resemble the soldiers in the Tank Army with different-colored armor. They also seem to like Lin Chung's bamboo shoots (which Lin Chung did not know that they can also be edible).
- Twin Masters (voiced by Scott McNeil) - Twin Masters is a two-toned demon who is HighRoller's master and uses him in his overall scheme to plunge the world into chaos. Twin Masters' head resembles a skull with small, glowing yellow pupils. On his right side, he is red and somewhat jagged, resembling lava and fire. On his left side, he is blue and wavy, resembling water and ice. His red half speaks with a gruff voice, while his blue half speaks with a more shrill voice. Twin Masters was once a warrior prince named Yang Tu who wanted to take over Hidden Kingdom. Lin Chung tried to change Yang Tu's fate, but Yang Tu fell into a deep volcanic pit into the Earth. Yang Tu was trapped inside until he became Twin Masters and mastered the power of chaos. Among Twin Masters's powers is the manipulation of unstable chaos energy, making his attacks utterly destructive. A few of the animals know of him from legends, rarely appearing outside his cave until the actions of First Squad force him to reveal himself and take a more active role. In "The Return of the Pterodactyls", he commanded the bald eagles to drink the sap from the ancient trees of the Hidden Kingdom which turned them into pterodactyls. He also turned animals into monsters through schemes involving a storm while having Mighty Ray's eyeballs and later enchanting the Owl Amulet. He hypnotized Second Squad which means he has hypnosis powers. By the end of Season 2, Twin Masters gains water from the lake of Tai Chi and encases himself in a giant cocoon to assume a powerful form. His skull-like head becomes more luminescent red and blue. He also has a snake tail in place of legs, with spikes at the end of his tail. It took the combined abilities of Big Green and all the Animal Kings and Queens to form the Bronze Giant in order to destroy Twin Masters.
- HighRoller (voiced by Brian Drummond) - A former trainee under Chiung Ming, he was once a court jester who ended up banished from the Eastern Capital for insulting its emperor and wandered into the Hidden Lands. Upon getting struck by lightning, he gained the ability to communicate with animals and tricked them into thinking humans were their enemies. As the new Emperor of the East Citadel, HighRoller gets to do whatever he wants, and what he typically wants to do is attack humans (or get animals to attack humans for him), eat candy, read comic books, and play games. A flashback in "Folk Game Competition II" revealed that he was a classmate of Woo the Wise. HighRoller is also the master of the Folk Game Competition and these skills actually translate to the battlefield in dangerously unexpected ways. For the first Folk Game Competition he held, HighRoller held it to distract everyone from the traffic. He later held the second Folk Game Competition as a diversion for the Zebra Brothers to eliminate all the books, since he hated studying as a child. He once beat Jumpy Ghostface in the first Folk Game Competition (by cheating), but the second one against Lin Chung ended in a draw when HighRoller discovered that the Zebra Brothers also took his comic books. Combining this with the fact that he likes to play dirty makes HighRoller a formidable opponent for even the most skilled members of First Squad, as even Lin Chung can have a hard time trying to stop him one time when HighRoller combined with Bearstomp to form the High-Stomp formation as seen in "Firework Festival at East Citadel" and "Strongest Punch & Kick". In Season 2, he is the servant of his master Twin Masters as seen in "The Rise of Lin Chung". In the Chinese dub, HighRoller was Kao Chao and his origin was different as in the Chinese version, he was the true emperor until a magic arrow shot his head stealing his ability to speak English but gaining the ability to speak animal language instead. In the Romanian dub, he was renamed Sportiflex.
- The Zebra Brothers (voiced by Adrian Petriw and Brian Drummond) - Two Zebra twins that serve High Roller. Sparky Black is a black zebra with grey stripes and Sparky White is a white zebra with black stripes. It has been shown that they, like Commander ApeTrully, were students of Parrot King; however, the Parrot King did say that they were his worst students (because they always goofed off in class). In almost all of the episodes, they are usually the ones who incite the animals to oppress the humans. In most cases, they stay out of fights between First Squad and the animals. However, once a month, when the moon is full, they use their most powerful weapons called the Ghost Lanterns. The Ghost Lanterns are paper lanterns on sticks that gives the Zebra Brothers supernatural powers ranging from merging to form a giant version of themselves, creating an army of zebra clones, create zebra-type mosquitoes, or getting their victims to face their biggest fears. Although in one episode, it was shown that the Zebra Brothers can twirl their lanterns and use them to fly, even without the full moon. In most episodes like "Cat Castle" and "Snake Castle", they end up in the same predicament as Commander ApeTrully. In the final battle against Twin Masters, the Zebra Brothers join Big Green to help form the Bronze Giant. Once Twin Masters is destroyed by Bronze Giant, the Zebra Brothers and Bearstomp leave with HighRoller to return to East Citadel.
- Bearstomp - Bearstomp is the armored King of the Bears who wears a helmet with a cannon on it. He acts as HighRoller's bodyguard. He is often shown blowing nose bubbles while asleep. One of his arms has been replaced with a retractable winch/pincher (suggesting that he may have been injured in battle). It is unknown as to how he acquired such a device, but it seems likely that HighRoller gave it to him as an incentive to enslave humans and become a prominent leader of HighRoller's army. In "Firework Festival at East Citadel" and "Strongest Punch & Kick", Bearstomp is shown to have the ability to combine with High Roller to form the "High-Stomp" formation which allows High Roller to be much tougher. In "Gladiators" Bearstomp is among those who were captured by the Minotaur's minions. First Squad and Bearstomp had to work together to escape the Minotaur. When Lin Chung offered Bearstomp to switch to their side, Bearstomp just hits Mighty Ray and returns to East Citadel. Although Lin Chung stated that Bearstomp is their enemy, he was their ally in the battle against the Minotaur. In "The Bronze Giant," Bearstomp joins Big Green to help form the Bronze Giant (classified as Hero 052). Once Twin Masters is destroyed by Bronze Giant, Bearstomp and the Zebra Brothers leave with HighRoller to return to East Citadel.
- The Soldiers of Darkness - A group of animal-hating humans who want revenge on the animal community. They kidnapped the Parrots from Parrot Castle under the orders of their leader, the Commander of Darkness (voiced by Scott McNeil in Season 2). According to Parrot King, the Soldiers of Darkness leave skull marks wherever they go. Jumpy Ghostface and Parrot King accidentally discover their underground base where they are captured and brought to the Commander. They try to reason with the Commander but he does not care if they have reformed. During this encounter, Jumpy Ghostface blows out the candle the Commander of Darkness wears on his hat, revealing the Commander has nyctophobia (a fear of the dark which Jumpy & Parrot King find funny). The Commander imprisons Jumpy and Parrot King, but they and the other Parrots are freed by the Zebra Brother's and their Zebra Clone Army (Jumpy & Parrot King however are captured by the Zebra Clones). The Zebra Clones knock over the Commander's candles, causing him to order a retreat. While they are fleeing it is revealed that there are only 6 Soldiers of Darkness (including the Commander). After being defeated and losing their Zebra Clone Army to the Butterflies, the Zebra Brothers run into the Commander and Soldiers of Darkness, who take out their anger on the pair. In "Revenge of the Commander of Darkness", the Soldiers of Darkness entrap a Giant Centipede and harvest its earwax in order for the Commander of Darkness to assume the form of Koala King and for his soldiers to be modified to be larger and have extra arms. When Commander ApeTrully and First Squad find out that Koala King was replaced by the Commander of Darkness, Lin Chung, Jumpy Ghostface, and Mystique Sonia fight the modified Soldiers of Darkness while Commander ApeTrully and Mighty Ray find Koala King. Once Koala King is rescued, the Soldiers of Darkness are defeated as the Commander of Darkness is forcefully dragged away by the Giant Centipede. In "Enter the Dragon", the Commander of Darkness gets a hold of some dragons and uses them to capture Mystique Sonia in order to force her to be his fellow Commander causing First Squad and the Air Force to go after her. Using her flute, Mystique Sonia charms a dragon which she uses to defeat the Commander of Darkness. The Commander of Darkness then surrenders and is used as a partner for Porcupine King's quill-shooting act.
- Cocky Aliens - A race of aliens who can only be defeated by being kicked 100 times (which leads to the invention of the game Shuttlecock) after which they turn into fruit (explaining the origin of pineapples, grapes, tomatoes, and watermelons). They are enemies of the Cheetahs as they were the ones who invented Shuttlecock. In "Cheetah Castle", a Cocky Alien in a large alien suit crashed First Squad's Shuttlecock contest against the Cheetahs by abducting the Cheetahs, Commander ApeTrully, and the other First Squad members. Using the advice of Jumpy, Lin Chung combined with the Cheetahs and destroy the Cocky Alien's suit. When the Cocky Alien sets himself to explode, Lin Chung kicked the Cocky Alien 100 times turning it into a pineapple. In "Cheetah Castle II", four Cocky Aliens later attacks Cheetah Castle and trap it in a Crystal Barrier. This time, HighRoller tries to trick them to his side. They managed to demonstrate an ability to possess humans by entering one's heads, which they did with High Roller, the Zebra Brothers, and Bearstomp. When High Roller, the Zebra Brothers, and Bearstomp are defeated, the Cocky Aliens end up possessing the other First Squad members. Lin Chung pretended to get hit in order for him to get them to leave the bodies of First Squad. Lin Chung, the Cheetah King, and Cheetah Queen then kick them 100 times and reduce them to fruits.
- Spotter the Rabbit - Spotter is a Rabbit who competed against Jumpy Ghostface to be the Rabbit King's successor. Rabbit King selected Jumpy Ghostface to be his successor instead of Spotter the Rabbit causing Sparta to leave. Upon training with some bad guys and mastering the full human language, Spotter befriended the Mantis army and they invade Rabbit Castle where he captures all the Rabbits leaving one to let Jumpy Ghostface know that he is back. While First Squad and the Beetles fought the Mantis Army, Jumpy Ghostface dueled with Spotter the Rabbit. After Spotter the Rabbit was repelled and the Mantis Army also takes their leave, the other Rabbits were rescued.
- Minotaur - A Minotaur resided in a labyrinth that contained a gladiator arena as seen in "Gladiators." In battle, the Minotaur can elongate his horns. The Minotaur's minions captured First Squad, Bearstomp, and some other warriors to fight for his entertainment. After Jumpy Ghostface discovered the power source for the control collars, Lin Chung destroyed the collars enabling the captives to escape and navigate through the labyrinth. After defeating the Minotaur's minions, the Minotaur attacked the group. Lin Chung managed to hold off the Minotaur while the others got out of the collapsing labyrinth. Upon emerging from the rubble, Lin Chung thinks the Minotaur was vanquished in the cave-in. After the group leaves, the Minotaur emerges from the rubble.
- Bounty Hunters - Two unnamed bounty hunters hired by Twin Masters to capture First Squad and to make up for HighRoller's failure. One bounty hunter is a sword-wielding lion-like bounty hunter where the lion-like head on his chest can extend out in battle. The second one is a cobra-like Nāga that can extend its tongue and piloted a snake-like train that carries its victims. The bounty hunters successfully captured First Squad much to the disappointment of HighRoller. When the bounty hunters were en route to rendezvous point to meet up with Twin Masters, HighRoller, the Zebra Brothers, and Lizard King caught up with them to recapture First Squad where they were tricked into freeing them as the bounty hunters took notice. When the train meets up with Twin Masters, he finds HighRoller and the bounty hunters in a cage as High Roller states that the capture of First Squad didn't work out the way it was planned much to the disappointment of Twin Masters.
- Turtles - The Turtles ride on tank treads to serve as transportation for First Squad and Second Squad when they were the first animals to join Big Green. They are classified as Hero 075. Some turtles are often seen wearing cannons on their backs. The Turtles come in different sizes from tank size to the size of roller skates. The Turtle King is the head of the Turtles and does not like it when the other Turtles are bullied by anyone like the time when Mighty Ray insulted his Turtle for being too fat causing the other Turtles to attack him with their cannons as seen in "Rhino Castle". When Mr. No Hands asks, Turtle King states that "when a turtle is hurt by a friend, the pain of the betrayal gives a tear strength to travel many miles, then the Turtles will always rush to the aid of a crying comrade." When not transporting First Squad to the scene where Commander ApeTrully is in trouble, they are often used in the Turtle Cannon Competitions between First Squad and Second Squad. In "Big Baby Turtles", the turtles associated with First Squad get exhausted while pursuing the Zebra Brothers after they stole the Owl Amulet from the Owls. First Squad decide to give the Turtles a vacation, but they run away from Big Green upon mishearing First Squad. The Turtles find the Zebra Brothers enabling them to give HighRoller and Twin Masters the idea to use the Owl Amulet's powers to turn the Turtles into their monstrous forms complete with fire-breathing abilities. High Roller and the Zebra Brothers disguise themselves as members of First Squad in order to trick the monstrous Turtles. Due to Mighty Ray having eaten a turtle egg at that time, he slowly turned into a Turtle causing First Squad to call in Kowloon to cover for Mighty Ray. When the monstrous Turtles attack a village, First Squad and Kowloon had to fight them. With the help of Mighty Ray's turtle form, First Squad and Kowloon had to reason with the monstrous Turtles. HighRoller attacked Mighty Ray enough for him to spit out the egg he swallowed from which a baby turtle hatched from and saw Mighty Ray as its mother. The monstrous Turtles then turn against HighRoller after he caused the baby turtle to fall on its back while attacking Ray. Lin Chung destroys the Owl Amulet breaking the spell on them.
- Rabbits - The Rabbits were the first seen by the audience where they capture Commander ApeTrully when he found out that the Rabbits like candy rather than carrots. They had him wear a carrot costume and jump rope. They use jump ropes for attacks and even have a bad-smelling belch attack. When Mystique Sonia and Mighty Ray end up captured upon being knocked out by the Rabbit's belching and end up in the same position as Commander ApeTrully, Lin Chung came to their rescue enabling Mighty Ray and Mystique Sonia to turn the tides against the Rabbits. Their leader Jumpy Ghostface (also known as the Rabbit King) went up against First Squad in a jump-rope battle. After being defeated, Jumpy Ghostface joins Big Green as a member of First Squad. In "Ninja Fight", it was revealed that there was a previous Rabbit King who selected Jumpy Ghostface to be his successor instead of Spotter the Rabbit causing Sparta to leave. Rabbit Castle was later attacked by Spotter the Rabbit and his Mantis allies where he captures all the Rabbits leaving one to let Jumpy Ghostface know that he is back. While First Squad and the Beetles fought the Mantis Army, Jumpy Ghostface dueled with Spotter the Rabbit. After Spotter the Rabbit was repelled and the Mantis Army also takes their leave, the other Rabbits were rescued.
- Bears - The Bears are one of the allies of HighRoller with some of them serving as HighRoller's Infantry. Seeing as the Bears were valuable to HighRoller, he once wagered to give up Bear Castle to Big Green if they won as seen in "Folk Game Competition". The Bears come in many different colors and some of them wear occasional clothing. Bearstomp is the king of the bears. They apparently have good driving skills as they pilot Duck Cars and stolen Big Green tanks with ease. The Bears are also good at Table Soccer as it was seen in "Table Soccer Competition" where Commander ApeTrully and First Squad had a hard time knocking the Bears off the poles and winning the game.
- Elephants - The Elephants use their long noses to attack in which they become deflated and must be re-inflated. The Elephant King enjoys blowing party whistles. First Squad went up against Elephant King in a contest to blow the largest party whistle. When First Squad managed to do that, Elephant King collapsed upon this reaction. After having his heart restarted by Mighty Ray's eyeball attacks, Elephant King joins Big Green (classified as Hero 105) where he operates an air conditioner-like device the helps all of Big Green stay cool in the summer, but gives Mighty Ray a cold. In "Camel Castle II", Lin Chung brought Elephant King to Camel Castle to unflatten the other First Squad members. In "Elephant Castle II", Elephant King learns about creativity from Mystique Sonia during his job. While out on his walk trying to find his creativity, the Zebra Brothers lied to Elephant King that First Squad and Big Green are mistreating him causing Elephant King to return to Elephant Castle and have the humans make tanks for the Elephants. When Commander ApeTrully gets captured trying to get Elephant King back, First Squad had to get Elephant King back without Lin Chung (who came down with a cold from too much cold air). Due to Jumpy Ghostface deflecting the Elephant's water attack, the Elephants ended up getting muddy enough for Mystique Sonia to use her tongue attack to blow off the mud when combined with the Elephant's spinning trunks. The Zebra Brother's deception were exposed causing Elephant King to send them flying toward the angry people the Elephants oppressed. Elephant King used his creativity to mix different flavors when blowing air throughout Big Green. In "Pitched Battle of the Air Force", Elephant King alongside Peacock Queen, Octopus King, and Scorpion King were used as test subjects for Woo the Wise's crystal Rubik's Cube-like invention. In "Big Baby Turtles", Elephant King auditions as a stand-in for the Turtles and is rejected due to him being too heavy for the Turtle's tank treads. In "The Bronze Giant", Elephant King is among the animals who helps Big Green to form the Bronze Giant in the final fight against Twin Masters.
- Ligers - The hides of the Ligers are tough enough for attacks to not harm them. They first are shown tricking Commander ApeTrully and the Tank Army and capturing them. They also burn away Mystique Sonia's Yaksha with their fire breath, which later comes back because a member of the Tank Army told Sonia he loved her three times. They have a pride in throwing rings when their leader Golden Eye Husky challenged First Squad to a ring-throwing competition. Though he beat First Squad, he is defeated in the ring-throwing competition by the Sailor Brothers. The Ligers join Big Green where Golden Eye Husky becomes a member of Second Squad.
- Camels - The Camels enjoy drawing and use their stinky spit as a weapon. The Camels captured Commander ApeTrully during his mission and use him as a model for their drawing. When it came to their fight with First Squad, their spit ended up causing First Squad to retreat. With help from Woo the Wise and the Air Force, the Camels ended up eating gum that did not make their spit smell bad. First Squad then confronts the Camel King. After being amazed by Lin Chung's drawing, Camel King joins Big Green (classified as Hero 046) where he becomes an art teacher to Lin Chung and draws up maps for Big Green. In "Eagle Castle", it opens with Camel King painting a picture of Commander ApeTruly in the desert. When ApeTrully tries his first attempt to make peace with the Eagles, Camel King warns him to be careful. In "Pitched Battle of the Tank Army", he tells Lin Chung to add more life to his drawings. In "Camel Castle II", Camel King has a vision of the cosmos following a hit on the head which gives him the inspiration to beat Lin Chung by painting a modern art picture of Mystique Sonia. Camel King declares his superiority and leaves Big Green to have the Camels show their art superiority to humans. This time, the Camels modified themselves with cactus launchers and paint cannons when driving away the humans. Commander ApeTrully had to call the Infantry to protect the humans from the Camels. When Commander ApeTrully fails to get Camel King back who uses Commander ApeTrully as a model again, First Squad had to try to get to Camel King without Lin Chung. When First Squad is trapped under a rock pushed by the Camels, the Turtle Tanks informed Lin Chung of this. Upon confronting Camel King while Elephant King helped the other First Squad members, Lin Chung showed Camel King his modern art hybrid of the flattened First Squad members. Camel King then returns to Big Green upon admitting defeat. In "The Bronze Giant", Camel King is among the animals who helps Big Green to form the Bronze Giant in the final fight against Twin Masters.
- Parrots - The Parrots occasionally ride on snails and can drop pellet bombs. They are ruled by the Parrot King who was a teacher to animals including Commander ApeTrully when it comes to teaching them human languages. Parrot King also considered the Zebra Brothers the worst of his students. He quickly joined up with Big Green (classified as Hero 024) after recognizing Commander ApeTrully's true form and his lie-detecting snail confirming that what Commander ApeTrully said about HighRoller was right. Parrot King gives out language lesson to the animals on Big Green's side.
- Pandas and Giraffes - The Pandas and Giraffes live together at Pandaffe Castle. The Giraffes would lift the Pandas onto their necks and throw them at enemies like a catapult. Panda King plays a Flute while Giraffe King plays drums. After being upstaged by Mighty Ray and Mystique Sonia earlier, Rattle Diva ended up helping them with her music which helped re-energize the Giraffes and Pandas. When the Pandas end up on the clouds upon the Giraffes accidentally launching them up there, First Squad managed to rescue them. The Panda King and Giraffe King join Big Green (with Panda King's classification being Hero 067 and Giraffe King's classification being Hero 002) and are now part of the Do-Re-Mi band with Rattle Diva. In "Snake Castle", Panda King gives Mystique Sonia a flute which comes in handy when dealing with the Snakes. In "Frog Castle", the Do-Re-Mi Band were summoned to combat the Frogs. In "Strongest Punch & Kick", Panda King combines with Mr. No Hands to form a fighting combination in order to combat the Gorilla-Roo formation. In "The Bronze Giant", Panda King and Giraffe King are among the animals who help Big Green to form the Bronze Giant in the final fight against Twin Masters.
- Eagles - Commander ApeTrully tried many times to get the Eagles to join Big Green. In "Eagle Castle", they carried a metal skeleton created by the Zebra Brothers which trapped Commander ApeTrully in his helicopter. Lin Chung managed to get Commander ApeTrully and his helicopter out of there. Lin Chung and the Air Force ended up getting him out of there causing Commander ApeTrully, Lin Chung, and the Air Force to fall back to Big Green. In "Air Battle", the Zebra Brothers having the Eagles attack Big Green. They were successfully shot down by the Air Force. Following the Eagle's failed attack on Big Green, the Zebra Brothers returned to Eagle Castle and discovered that the Eagles have lost the feathers on their heads. This ended up turning them into bald eagles. In "Bald Eagle Castle", the Zebra Brothers ended up capturing Commander ApeTrully for the Eagles' revenge. Their baldness gave them an advantage using their shiny baldness to blind anyone when the light of the sun is reflected off their heads. Lin Chung and the Air Force managed to shoot them down from their twister position. Because the Zebra Brothers had to pull them out instead of digging them out, the bald eagles ended up becoming ostriches and chased after the Zebra Brothers for what they did to them. Also, it caused them to lose their flight in a plot to attack Big Green. In "Ostrich Castle," the Zebra Brothers had the Ostriches help them in fighting First Squad. When fighting First Squad, the Ostriches can join together into a bird ball-like formation with their heads sticking out. The Zebra Brothers pretended to join Big Green in order to steal the secrets of Big Green and help the Ostriches design their own launch tubes to form their own launch tubes. After the entering the Zebra Brothers' Mimic of the First Squad entrance, they gain their ability to fly again (the Zebra Brothers actually did not plan this, but they promise) restoring them to bald eagles and put them through drills. Unfortunately when it comes to attacking Big Green, the bald eagles thought it was another drill and ended up smashing the signal leaving the Zebra Brothers at the mercy of First Squad. In "Pitched Battle of the Air Force", HighRoller later had the bald eagles combine with the bats and hens in order to form the Ultimate Flying Force. Big Green's Air Force and First Squad had a hard time fighting the combined forces of the bald eagles, the bats, and hens until they were defeated. The bald eagles retreated leaving the bats and hens behind. The bald eagles later operated by a fake black dragon and defeated them. Mighty Ray toying around with Woo the Wise's invention caused HighRoller, the Zebra Brothers, Bearstomp, and the bald eagles to merge into a large creature he called the "Twelve-Eyed Striped Dumbat." Upon being broken apart by a combined attack by Lin Chung and the Air Force, the bald eagles retreated with HighRoller, the Zebra Brothers, and Bearstomp. In "The Return of the Pterodactyls", Twin Masters commanded the bald eagles to drink the sap from the ancient Fruiters Bum-Bodda trees of the Hidden Kingdom which turned them into Pterodactyls. In "The Yeti & Phoenix", Twin Masters turns Bald Eagle King into a fire-breathing phoenix to cause havoc in Hidden Valley. Jumpy Ghostface and Mr. No Hands had to fight the Phoenix until Lin Chung arrived and had them trick the Phoenix into going towards the Yeti (which was a transformed version of Polar Bear King). While the Phoenix and the Yeti were locked in combat, Lin Chung channeled the Harmonic Energies of his teammates in order to regress the Phoenix and the Yeti back into Bald Eagle King and Polar Bear King enough to thwart Twin Masters's plot. Afterwards, Bald Eagle King finally sides with Big Green (classified as Hero 11). In "The Bronze Giant", Bald Eagle King is among the animals who helps Big Green to form the Bronze Giant in the final fight against Twin Masters.
- Baboons - The Baboons have been stealing water from the humans. They're not evil, but High Roller infected them with fleas that made them evil. They use spinning tops as weapons making fire monsters when the tops burn the wood. When Commander ApeTrully had a broken leg, Woo the Wise and Parrot King had to cover for him. However, instead of making peace with them, Woo the Wise confronts them saying "You Baboons should be ASHAMED of yourselves! STEALING water from humans for your baths! You ARE very SELFISH!" The Baboons agree with Woo the Wise and Woo the Wise is overjoyed when he was finally right for once. After the Fleas wake up, the Baboons become angry and Woo the Wise ends up infected by the Fleas. After Woo the Wise realizes that his words have provoked the Baboons, he also notices his clothes are gone except for his Birthday suit and First Squad was called in. During the fight against the Baboons, Mighty Ray used his Electrical Eyeball Attack on the clouds which made the fleas dormant. When the fleas were no longer dormant, the Baboons ended up infecting Jumpy Ghostface with fleas. First Squad had to go up against the Baboons in a top-spinning battle. When Jumpy gets flat, Lin Chung ends up spinning Mighty Ray into a tree containing Soapberries which when exposed to water made Mighty Ray smell clean. With help from Mystique Sonia, Mighty Ray ended up defeating the Baboons and exposed them, Woo the Wise, and Jumpy Ghostface to the Soapberries. After being freed from the evil fleas, the Baboons join Big Green where they are doing laundry for Big Green. In "Elephant Castle II", Baboon King warned Commander ApeTrully that there is something wrong with Elephant king. In "Sheep Castle", Yaksha summoned Baboon King to help get the oil off of the Sheep's wool.

HighRoller ended up taking Chameleon Queen on a mission to steal a box containing diamonds that summon demons that can turn any human into an animal. HighRoller modified Chameleon Queen and her subjects with armor made from the bells from an old bell tower the Zebra Brothers accidentally destroyed and tank treads to match the armor and tank treads of the Turtles. Chameleons are known to use camouflage for their stealth attacks. In "Chameleon Castle", Commander ApeTrully ended up trying to make peace with the Chameleons only for him and the Tank Army to be ambushed by HighRoller, the Zebra Brothers, the Bears, and the Chameleons. With the Calabash Tanks damaged, First Squad and the Tank Commander had to get Gardener Ching to grow more Calabash Tanks. After Lin Chung freed Commander ApeTrully and the Tank Army following the removal of the fog, Chameleon Queen and her subjects, HighRoller, the Zebra Brothers, and the Bears were repelled with the Tank Army's Skywheel attack. In "Turtle Cannon Competition III", the Zebra Brothers blamed Chameleon Queen for eating HighRoller's candy causing HighRoller to kick her out. Chameleon Queen teamed up with Second Squad to do the Turtle Tank Race where First Squad and Second Squad had to race within Chameleon Queen. After HighRoller learned that the Zebra Brothers framed her and stole the candies for themselves, she was enticed back to HighRoller's side when he offered her candy opposed to Commander ApeTrully's offering of gold present. In "The Rise of Lin Chung", HighRoller unleashes the Chameleon Tanks on First Squad and Kowloon after they destroyed his Magma Cannon while Chameleon Queen holds Commander ApeTrully over a volcano. Lin Chung arrives to help fight the Chameleon Tanks as HighRoller orders Chameleon Queen to drop Commander ApeTrully into the volcano. Lin Chung rescues Commander ApeTrully as HighRoller and Chameleon Queen get away before the volcano erupts. In "Duo Cannons", HighRoller equips the Chameleon Tanks with a special liquid (made from the Rock Caterpillar's silk and a special ore) as part of a plan to trap First Squad in the liquid. When Commander ApeTrully, Jumpy Ghostface, and Mystique Sonia end up petrified, Lin Chung and Mighty Ray had to enter Chameleon Queen where HighRoller is making another batch of the liquid. When Lin Chung and Mighty Ray attack, HighRoller has the Chameleon Tanks and the Rock Caterpillars attack. After Lin Chung destroys the barrels containing the liquid and then evacuates after getting the Rock Caterpillars out, Chameleon Queen was in pain enough to slowly back up towards the cliff it was on. Lin Chung and Mighty Ray then push Chameleon Queen off the cliff enough to free Commander ApeTrully, Jumpy Ghostface, and Mystique Sonia from the casings they were in. In "The Bronze Giant", Chameleon Queen helps High Roller, Bearstomp, and the Zebra Brothers to hold off First Squad while Twin Masters evolves into a powerful form. Chameleon Queen later joins Big Green to help form the Bronze Giant.

Peacocks are good at telling time even when it comes to the Peacock Queen's tea time as two of each Peacock can combine to form a clock. When Commander ApeTrully and most of First Squad end up under her spell, she discovers that Mystique Sonia is only admiring her own beauty. This leads to a contest where each of them has to fan out the flames of a nearby volcano which Peacock Queen won. Yaksha ended up stealing some of Peacock Queen's feathers and redesigning Mystique Sonia enough for Peacock Queen and the Zebra Brothers to activate her curse which also releases First Squad from Peacock Queen's spell. After Mighty Ray zaps Mystique Sonia, Peacock Queen discovers that Yaksha also loves Mystique Sonia for what's inside. After releasing the humans from her spell, Peacock Queen joins up with Big Green (classified as Hero 076) and uses her wind attack on the Zebra Brothers when they disrupt her tea time. Due to the Peacock's talents of telling time, the Peacocks are given the job of being Big Green's timekeepers.

When Commander ApeTrully tries to reason with it, Lady Green discovers that the "ghost ship" is a sea creature as it captures Commander ApeTrully. Lantern Fish King goes into a trench that proves too deep for Sammo to follow. While the others return to the surface to tend to Sammo, Lin Chung and Lady Green continue to pursue Lantern Fish King. Lin Chung and Lady Green were able to enter Lantern Fish King's mouth where Lantern Fish King sics a hypnotized Octopus King and Stingray King on Lin Chung and Lady Green. Upon rescuing Commander ApeTrully, Lin Chung and Lady Green were able to block Lantern Fish King's hypnotic control on Octopus King and Stingray King.

They can also alter their size as one leach was shown to appear in the size of a real leech and then it grew. HighRoller had tricked them into attacking Big Green where Leech King and three of his Leeches infiltrated the Big Green base disguised as the King of Lions. The Leeches were able to assume the form of Commander ApeTrully, Mighty Ray, Jumpy Ghostface, and Mystique Sonia. Lin Chung knew something was wrong and attacked the imposter Commander ApeTrully who was actually Leech King in disguise. Lin Chung ended up fighting Leech King even when he manages to assume the form of Lin Chung.

- Seahorses - The Seahorses can shoot water from their mouths and can act as water guns. The Seahorse Prince and his army first appeared where they helped First Squad repel the Flying Fish army. First Squad ends up hooked on the Seahorses special abilities. HighRoller challenges First Squad using Seahorses where the Seahorse Prince states that the Seahorses used by High Roller is a rebel faction led by Seahorse Prince's twin brother. Both sides end up in a water fight where it is shown that Twin Masters is feeding off the energies of the fight until both sides destroy themselves. Upon noticing Mystique Sonia's behavioral change towards Yaksha, Lin Chung figures out what is happening as Sea Horse Prince states that Twin Masters has promised that both sides will be the weapons between both Sea Horse factions. Lin Chung uses his Harmonic Energies to disable the Seahorses' hypnotic effects to get the truth out to the rest of First Squad and HighRoller's side. When both Seahorse Brothers combine into one Seahorse to attack, both sides were able to defeat the combined Seahorse as Lin Chung separates the Seahorses back into the Seahorse Brothers who end up retreating. In "The Bronze Giant", Seahorse Prince's brother joins up with Big Green to help form the Bronze Giant.
- Sloths - The Sloths wear coats that make them slow. But when the coats are removed, the sloths can move fast. Sloth King and his army attacked hidden kingdom because they thought humans were cutting down trees and they thought they would have nowhere to live.
- Hyenas - Legend said that some humans stole treasures from the Animal Lords and hid them in their cave. The Animal Lords invoked a curse which turned the thieves hideout into the Spirit Cave that turns anyone into their inner animal with the thieves being turned into Hyenas. When First Squad arrived at the Spirit Cave, they ran into a pack of Hyenas who end up attacking them. The Hyena King then uses its ear-splitting cackling on First Squad. After Mighty Ray fought the sounds to knock down the Hyenas due to him wearing earplugs, First Squad continued their battle against them and managed to trap them in a cave-in. First Squad then enters the Spirit Caves to assume their inner animals before the Hyenas can get out of the cave-in.

- Polar Bears - The Polar Bears are the arctic offshoot of the Bears. In "The Yeti & Phoenix", Twin Masters turns Polar Bear King into an ice-elemental Yeti to cause havoc in Hidden Valley. Mystique Sonia and Mighty Ray had to fight the Yeti until Lin Chung arrived and had them trick the Phoenix into going towards the Phoenix (which was a transformed version of Bald Eagle King). While the Phoenix and the Yeti were locked in combat, Lin Chung channeled the Harmonic Energies of his teammates in order to regress the Yeti and the Phoenix back into Polar Bear King and Bald Eagle King enough to thwart Twin Master's plot. Afterwards, Polar Bear King joins up with Big Green.
- Roto-Wolves - The Roto-Wolves are a type of wolf that wears a helicopter pack. They can launch their claws in battle and throw the helicopter blades on their back as a boomerang when on the ground.

Upon being able to signal the rest of First Squad, Mystique Sonia and Mighty Ray were able to get out of the tunnels that was flooding with magma. Lin Chung used his Harmonic Energies to stop the magma and return the Ants back to their normal size.
- Komodo Dragons - The Komodo Dragons have lived since the days of when Twin Masters was a warrior. They can breathe fire and shoot the spikes that are on their bodies. Twin Masters used them to attack First Squad. When Lin Chung went back in time, he saved the Komodo Dragons from Yang Tu's wrath, causing them to give up their evil ways and the Komodo Dragons never turned against the humans in the present.
- Blowfish - In a plot to sink Big Green under the ocean, High Roller enlists the Blowfish King and his army to assist him. The Blowfish can inflate themselves and shoot their spikes. HighRoller uses the Blowfish army to distract First Squad, Lady Green, the Sailor Brothers, and Sammo so that the Blowfish King can complete his mission. The Blowfish King is colored pink instead of blue and appears to be the smallest of the Blowfish but when inflated he is the biggest of all the Blowfish. Blowfish King get to Big Green before Lin Chung can stop him. Blowfish King uses his spikes to put holes in Big Green which then causes water to enter Big Green.

- Swamp Hippos - Twin Masters placed chaotic energy into the mouth of the Swamp Hippo King causing him and the other Swamp Hippos to attack the nearby village.

The Swamp Hippos attacks caused the people to believe that the Dogs were responsible causing First Squad and Wu Sung to be called in. While on the trail of Dog King, the group is attacked by the Swamp Hippos where they end up finding some of the Dogs captive. With help from Dog King, First Squad and Wu Sung end up freeing the Dogs and fighting the Swamp Hippos. Wu Sung managed to extract the chaotic energies from the Swamp Hippo King's mouth.

Hero: 108 has appeared in many Beanfun! commercials to sponsor Gamania which featured many flash-animated clips of previous episodes in which an event occurred which featured a big bean appearing being pixelated than the character disappears which features the bean transforming into a question mark and an exclamation point. None of the characters have any dialog at all in the commercials except Mighty Ray in one commercial where he says "Okay, Banana?".

- Sonia's Pimple: From the episode "Liger Castle". Mystique Sonia looks in the mirror and finds a pimple and Yaksha pops it which causes it to turn into a bean after it got out. The difference is that the pimple is green; not red and Yaksha pops it instead of Sonia stopping him. Although Sonia said "La la la" and screamed, this is not considered actual dialogue.
- Mighty Ray's Banana: From the second episode of the series "Elephant Castle". The only commercial with dialogue. Mighty Ray has to practice eating bananas but his banana will not shoot but when he tries harder, tiny beans shoot his face along with a huge bean that hits his eye. After the bean gets pixelated, Mighty Ray runs away scared.
- Jumpy's Daydream: Taken from the episode "Parrot Castle". Jumpy daydreams of being surrounded by dancing beans.
