Zak Saturday is the 11-year-old (he turns 12 in "Kur Parts 1&2, turns 13 in "Life in the Underground") major character of the show. The son of Doc and Drew Saturday, Zak seeks adventure at every turn, which is easily satisfied by his cryptid-researching family. Zak has an unorthodox upbringing that has taken him around the planet and placed him in the face of danger since the day he was born. Zak was born the same year the Kur Stone was found (specifically, he was conceived shortly after the discovery). Zak has a special psychic ability to connect with cryptids, allowing him to control their actions to an extent. Tamer cryptids seem to trust him instinctively and even fiercer ones can tell that Zak is different from other humans.
Zak's primary weapon is the Claw, a combination staff/grappling hook. The hook is a three-fingered claw called the Hand of Tsul 'Kalu, which acts as a focusing device for Zak's powers. Zak also seems stronger and more durable than a normal child his age, as he was able to climb a radio tower carrying a full grown man in "The Vengeance of Hibagon" and gets back up immediately after being thrown against a vent in "Black Monday".
For a while, it was believed that if the cryptid Kur was ever unleashed, Zak would be the only one with the power to stop it. However, in the season one finale "Kur Rising", after Zak defeated the creature that was believed to be Kur, the Kur-sensing Naga relic Doyle had repaired glowed not in the creature's presence, but in Zak's, meaning Kur was in fact Zak the entire time. Jay Stephens has confirmed that Zak is actually Kur reincarnated. It was eventually learned that the Kur Stone Doc and Drew discovered before Zak's birth contained Kur's essence. During the accident when it was uncovered, the energy was released from the stone and found a new host, namely, the unborn Zak. This was because, as Rani Nagi said, it was a much more dangerous form as it could exist between the worlds of humans and cryptids. This meant that Zak is half-cryptid. Despite the Saturdays trying to keep the truth about Zak's nature secret, the other Secret Scientists found out through unexplained means and began pursuing Zak, forcing the Saturdays to go on the run. The Nagas have also sought him, intending to have him embrace his inner nature and become their new master. Following Rani Nagi's attack on Manhattan, Zak and Fiskerton are approached by V.V. Argost, who offers Zak a deal that will "help [him] master his Kur abilities." Zak agreed to the plan, though Argost has informed him that he has his own hidden agenda. Zak later told Doyle (in secret) to find out as much as he can about Argost's past. During a fight with an Ahuizotl in "The Thousand Eyes of Ahuizotl", Zak discovered that his powers enabled him to sense cryptids (as well as move around as though not blind-folded) without seeing them. In "Into the Mouth of Darkness" it was revealed that some cryptids such as Fisk love Zak because of his Kur power. Epsilon and Francis' people also think that Zak is "a time bomb waiting to explode" and insist that they help train him. Although he has aged 2 years, not much has changed about his appearance, although he has grown a bit taller. Zak is known as fearless, reckless and unpredictable. It is hinted that Zak has feelings for a thief girl named Wadi (stated in Curse of The Stolen Tiger and Life In The Underground).
Solomon "Doc" Saturday is the patriarch and the "Indiana Jones"-like character who has spent his whole life studying cryptids. Doc Saturday naturally had black hair but after a fight with a guardian known as Tsul 'Kalu, Doc was shocked by the claw that originally belonged to Kalu, giving him a streak of white hair. The shock of energy made Doc blinded in the right eye. (This was confirmed in The Return Of Tsul'Kalu) A man who takes science very seriously, Doc is one of the Earth's leading experts in the field of cryptozoology.
Doc started his career on Honey island when he was 12, learning from Dr. Basil Lancaster. He is a supergenius, having built many of the gadgets the family uses. A loving father, he often tries to teach his son Zak responsibility. Doc is trained in fourteen different forms of martial arts. He fights with the Battle Glove, which is able to channel power into his right fist. The four crystals on the knuckles also have individual powers: freezing, heating, shocking, and sonic vibrations. Though his age is not definite, creator Jay Stephens has stated that he "imagined Doc as 40 or so."
It was revealed in the episode "The Return of Tsul 'Kalu" that Doc got his scar and blind eye from Tsul'Kalu while protecting Zak.
Drew Saturday is the matriarch and the one who "believes in the magic," being more prone to accepting things on faith rather than empirical evidence. Drew was born to a family of adventurer-scientists. After her family was scattered during a severe blizzard in the Himalaya, she was raised by monks which may have taught her to believe not everything needs a reasonable/scientific explanation. Years later, she was reunited with her long lost brother, Doyle (Jay Stephens stated that their parents didn't survive the incident). She is able to speak 37 different languages which in many episodes, comes in handy. Drew is always encouraging Zak to try new things like tribal dancing or sand painting, but when there's a risk of danger, Drew gets a little overly protective of her only son. She's a mystic who is well-versed in the Earth's cultures and can blend in anywhere her travels may take her. In 'And Your Enemies Closer', she and Doyle (whose search for Argost's past led him there) reunited in Himalaya at the same place that their family was lost. She then learns that it wasn't the blizzard that separated her and Doyle, but an attack on their camp by The Yeti. Much to her shock, she and Doyle discovered that the cryptid that destroyed their family is in fact Argost.
Drew's preferred weapon is the Tibetan Fire Sword given to her by the monks, which absorbs light and channels it into potent bursts of flame. Her sword needs light to access the fire, if there is no light source around it shoots blue flames. In "Food of the Giants" she shows her skill as an expert at wilderness survival. Like Doc, she is a skilled fighter. Though her age is not definite, Jay Stephens stated that he "imagined her as 34 or so."
Fiskerton, often called Fisk by Zak, is a seven-foot-tall "gorilla-cat" with glowing red eyes, based on the Fiskerton Phantom. He was adopted by the Saturday family when his home was burned down by the locals in Nottinghamshire, England. Although he is the oldest and largest member of the family, Fiskerton is like an innocent brother to Zak. He may be a coward at times, but he is proven to be a great and strong ally to have, willing to risk his life for his new family. He mostly talks in grunts and mumbling which occasionally mimic human speech, though the family is able to understand him regardless. Even Though Fiskerton is a cryptid and not human, he and Zak share a brotherly friendship.
Fiskerton has great strength, showing himself capable of ripping apart metal bare-handed and hold his own against larger cryptids. His feet are as dexterous as his hands, allowing him to climb things with ease. In "Once More the Nightmare Factory", it is revealed that Fiskerton is a Lemurian (a fact which Fiskerton himself was unaware of), a member of a race of creatures that guard the Earth against Kur and is able to locate Kur through psychic and instinctual means. He eventually leads the family and accidentally, Argost to where Kur will be revealed in Antarctica. Despite learning that Zak is Kur, Fiskerton continues to protect Zak, literally becoming the "Kur Guardian".

Komodo is a 250-pound, genetically-altered Komodo dragon with a voracious appetite. He has a unique power, which is becoming invisible. He also can make other objects invisible, such as when Doc hooks him up to the airship Komodo's powers turn the airship invisible as well. This power is something that comes in handy for stealth missions, though Komodo seems not to like it. His claws are also sharp enough to slice through metal. Though for the most part quite obedient, Komodo's actions are often dictated by his stomach and he will ignore the family for a good meal. Extending from this, Komodo will often pick fights with others to get food, even when his opponent is far larger and stronger (Komodo fights with the elephant-like Groot Slang over a piece of meat in "Something in the Water", for example). Like a rivalry between a cat and dog, Komodo often fights with Fiskerton. He seems to have a feud with Zon as well, as he attacks her at least twice. Like Fiskerton, Zak sees him as a brother. He also likes to eat Ulraj's kelp necklace, much to Ulraj's disliking.
- Voice Actor: Fred Tatasciore
Zon, named after the Amazon rainforest where she was found, is a surviving member of a thought-to-be-extinct Pterosaur species (Ornithocheirus) that lives in a nest near the Saturday Headquarters, but isn't truly owned by them. The Saturdays anger her by crashing into her nest during the second episode, but she comes to appreciate them after Zak saves her life. She now uses the cliffs where the Saturdays live as her new hunting grounds. Unafraid of humans, she allows Zak to comb her mane and ride her, but she absolutely resists the family's domestication efforts and refuses to give up the great outdoors. She is rather hostile towards Komodo. In two episodes, she is incorrectly referred to as a Pteranodon. Like Komodo and Fiskerton, Zak sees her as a family member, in this case as a sister. In "Kur, Part 1," Zon is revealed to be aiding Doyle in locating the missing V.V. Argost. She is currently helping Doyle find information about Argost's past.
- Voice Actor: Will Friedle
Uncle Doyle is Zak's biological uncle, Doc's brother-in-law and Drew's long-lost younger brother. He first appears as Van Rook's apprentice in "The Kur Stone". He helps Zak put a tribe of Amaroks back into hibernation in "The Ice Caverns of Ellef Ringnes", starting a stable relationship with him. At first, he and the Saturdays are unaware of any biological relationship. In "Van Rook's Apprentice", he changes sides and joins the Saturdays after learning he is Drew's brother and about V.V. Argost's true motives.
Though Doyle is admired by Zak, he and Drew have a small sibling rivalry and at first, he and Doc barely get along at all. Doc is annoyed by Doyle's tendency to show off and frustrated by Doyle's chaotic lifestyle, influenced by living as a mercenary—his tendency to bend or even break rules (and laws) in pursuit of his goals, his willingness to do questionable things in pursuit of money and particularly his tendency to take risks, as this proves an unfortunate influence on Zak, who sometimes imitates Doyle's risky behavior and puts himself at risk. Doyle resents what seems to him to be constant criticism by Doc of his methods and tactics, as well as what he perceives to be Doc being judgmental of his mercenary trade (which he resents, as Doc inherited his fortune, whereas he has had to work as a mercenary to support himself.) Eventually, they make up, as the threat from Argost grows greater and Doc recognizes the potential value of Doyle's unique skills. Doyle is something of a jack-of-all-trades, fighting using a combination of grenades, lasers, as well as hand-to-hand combat. He is strong enough to lift a grown man one-handed and is able to wrestle with cryptids much larger than himself.
As shown in "The Atlas Pin" he's shown to be not entirely reformed as he was willing to go behind Drew's back to gather the pieces of Rani Nagi's Kur relic. It was mostly because of Doyle that Kur was revealed to be Zak as he repaired the relic and brought it into the proximity of Zak at the end of "Kur Rising". Jay Stephens himself has already said that he imagined Doyle to be "28 or so".
In "Kur, Part 1," Doyle, aided by Zon and Van Rook, is looking for the missing V.V. Argost. After finding what seemed to be proof that Argost was dead, he reported his findings to the family. Zak secretly informed him that Argost was indeed still alive and asked him to search for information regarding Argost's past. With Zon and Van Rook continuing to aid him, he tracked down those who had connections to Argost's past, but it proved difficult as they kept not-so-mysteriously disappearing. In 'And Your Enemies Closer', his search led him to the Himalayan monks who had raised Drew after they were separated. Upon reuniting with Drew, she informs him that it was here that they lost their parents. Doyle recalls that he ended up sliding down the slope and wound up in an orphanage, which led to the way he grew up. He then reveals something shocking to Drew: it was not the storm that ruined their family, but an attack from a cryptid called a Yeti. Upon finding the beast's abandoned lair, Doyle and Drew make a shocking revelation: the Yeti who attacked their family, killed their parents, caused them to be separated and grow up in different ways was in fact Argost.
Allies and neutral characters
Leonidas Van Rook
- Voice Actor: Corey Burton
Leonidas Van Rook is a ruthless cryptozoologist who is the ally of V.V. Argost and a rival of Doc Saturday. Van Rook is interested in proving the existence of cryptids for money. He is very thrifty, almost to a fault. Similar to Doc, he is an inventor and has many high-tech gadgets. He and Drew dated in college, much to her dismay. After Doyle left him, Van Rook hired Abbey Grey. In "Kur" Pt. 1, Van Rook admits that he trained Abbey too well because she has taken over the mercenary business from him. He seems to have gotten out of shape between Season 1 and Season 2: Doyle pointed out that he had some extra gut room in his armor and he even admitted he was out of shape while fighting Munya. He has been recruited by Doyle to find V.V. Argost after he found Van Rook working with Ron Bantington. When Doyle and his quest to learn the secrets of Argost's past leads to Himalaya, they are reunited with Drew, who does not greet Van Rook with open arms. When the Himalayan monks who raised Drew lead them to the abandoned cave of the Yeti cryptid who destroyed Doyle and Drew's family, Van Rook discovers a camera on the ground among other items from camps it had attacked, which Van Rook saw as souvenirs, meaning that the beast attacked for fun and not food (or money), to which he said "Even I'm disgusted!".
He fought alongside the Saturdays in 'War Of The Cryptids', against Argost's cryptid army. He ultimately sacrifices himself to save Drew Saturday from a blast from her own fire sword when it was taken by Rani Nagi during the final battle at Weirdworld, saying she was the only thing he loved almost as much as money. After Argost was destroyed and his cryptid army retreated, the Saturdays and their friends paid their respects to their old enemy turned friend. Doyle says goodbye by tossing three flowers onto his grave, then takes one away and says, "Two is plenty." This refers to episode one, in which Doyle throws eight concussion grenades which hit Doc and Leonidas responds by growling "I told you two charges at a time was plenty, the other six come out of your pay!".
Dr. Arthur Beeman
- Voice Actor: Jeff Bennett
Dr. Arthur Beeman is a Secret Scientist who studies aliens and UFOs. However, far from being a conspiracy nut, his obsession is apparently justified as he saved the Earth from invasion by figuring out the 'crop circle code'. Beeman is often blunt and mildly insulting in his speech. He gives people nicknames based on their appearance (Zak's hair, for example, results in names such as "Skunk-do" or "Salt and Pepper"). Doc and Drew called him in to watch Zak, Fiskerton, Komodo, and Zon while they were away on their anniversary dinner. In "Kur" Pt. 1, he is one of the Scientists after Zak (and gave him a new nickname "Franken-hair"). In 'War Of The Cryptids,' it is found out that he has a recording from the Flute of Gilgamesh. He uses this against Zak and Argost, almost to the point of killing them. He is stopped by Miranda and is never seen again. Since a later episode of Ben 10 Omniverse reveals the Secret Saturdays reality is the same one as its, it is highly likely Beeman knows the Galvans since he has been once heard exclaiming "Sweet Galvan Prime!"
Dr. Henry Cheveyo
- Voice Actor: Diedrich Bader
Dr. Henry Cheveyo is another Secret Scientist who held a piece of the Kur Stone. Argost stole it, then used a cryptid parasite to extract the location of the third piece from him. He works at the Mesa Observatory in Arizona. He was seriously wounded when he took the brunt of an explosion meant to kill the Saturdays, but survived.
Dr. Miranda Grey
- Voice Actor: Susan Blakeslee
Dr. Miranda Grey is a Secret Scientist who held a piece of the Kur Stone until Munya stole it. She's an expert at quantum physics and works on particle acceleration in Antarctica with her robot sidekick Deadbolt. She has a gun which can create miniature wormholes, allowing her to physically attack opponents from a distance. She is Abbey Grey's sister and was dissatisfied that she sided with Leonidas Van Rook. In "Kur" Pt. 1, she is one of the scientists after Zak. In the "Thousand Eyes of Ahuizoti," it's revealed that she has been watching Weird World for surveillance. In "War of the Cryptids," Miranda had a change of heart as she saved Zak in the season finale from a copy of the song that would harm Kur. She attends Van Rook's funeral.
Deadbolt is a robot that is Miranda Grey's sidekick. In "Kur" Pt. 1 and "The Thousand Eyes of Ahuizotl", it assists Miranda in hunting Zak.
It's a recurring joke that in every episode he appears in he gets destroyed only to come back later new and improved. Miranda also mentions that Dead Bolt costs $37,000,000 to repair.
Dr. Paul Cheechoo
- Voice Actor: Danny Cooksey
Dr. Paul Cheechoo is a Secret Scientist that specializes in cold-climate research, he and a team of experts travel the Earth studying strange geological anomalies. He's currently stationed at Ellef Ringnes. In one episode he mentions he grew up in cold weather and he indirectly reveals at the end of "Where Lies the Engulfer" that he is from Canada. The Saturdays tend to cause, or at least get involved in, ecological disasters when they do any work near him, which he eventually points out with slight annoyance. He also has more of a sense of humor than the other Secret Scientists and seem to be the most friendly with Zak. He attended Van Rook's funeral.
Professor Talu Mizuki
- Voice Actor: Jerry Tondo
Professor Talu Mizuki is a scientist who invented a mind-swapping device for (unknown to him) crime lord and philanthropist Shoji Fuzen. When asked to use it to implant the mind of one of Fuzen's men into a Hibagon, he takes the Hibagon's body himself to prevent Fuzen from getting his hands on the Hibagon, which Fuzen sees as a potential superweapon. In the ensuing confrontation, his body is lost in a fire and the mind-swapping device is destroyed. He attempts to take revenge against Fuzen, but is convinced by Doc to let it go. He now lives in a cave lab alongside his white tiger (which was mind-swapped with a dog) working on a way to get his mind back into his body and continue his research. Apparently, he has become a member of the Secret Scientists as shown in "Eterno" where he helps the other scientists solve the Eterno crisis. In "Kur" Pt. 1, he is one of the scientists after Zak.
Talu's White Tiger
- Voice Actor: Adam Wylie
The young prince of Kumari Kandam (supposedly about a year older than Zak, making him 12 in the series) whose father was killed in an assault orchestrated by V.V. Argost. He allied with Zak to reclaim his kingdom from V.V. Argost. With help from the Saturdays, Ulraj reclaimed his kingdom, but V.V. Argost and Munya escaped with an ancient and powerful Sumerian medallion which Ulraj stated to be too dangerous to wield. In "The Underworld Bride," King Ulraj later helped the Saturdays when the Dua'a was trying to take Zon into the Underworld. In that episode, he exhibits the ability to detect electric fields. In "The Atlas Pin", Ulraj helps stop the Nagas from pulling the Atlas Pin. He has a friendly rivalry with Zak. In "Life in the Underground" he and Zak both compete for Wadi's affection with turns the friendly competition less friendly. Ulraj later admits he doesn't like Wadi, he just doesn't like losing to Zak.
- Voice Actor: Brian Stepanek
Agent Epsilon and his 11-year-old "son" Francis are members of a secret organization loosely allied with the Secret Scientists, though they have their own agenda. Epsilon is usually quite serious and by the book, personifying the "Men in Black" archetype (in behavior if not appearance). He also has access to "the files" which is a large database on everyone and everything. He also has a group called his "people" for protection. It is revealed in "The Unblinking Eye" that he and Francis are actually clones of the "perfect agent" their organization found 100 years ago.
- Voice Actor: Scott Menville
The 11-year-old "son" of Agent Epsilon. Francis is clever and manipulative, just like his "father". Francis wears a shield generator that shocks anyone who tries to touch him without permission. He and Zak have a rivalry, as evident in "The Swarm at the Edge of Space" and "Paris Is Melting". He is a bit jealous of Zak because he has a "normal" family and Francis does not. It was revealed in "The Unblinking Eye" that Francis and Epsilon are clones of a "perfect agent" their organization found 100 years ago thus explaining why he has no mother. Francis also explained that in time he will be given a "Francis" of his own to raise as Epsilon is raising him. He also showed a great disdain and bitterness over this fact, due to the massive amount of pressure it placed upon him. Zak tells him he's in charge of his own destiny and is his own person, not just another clone. Francis understands and allows Zak to escape instead of capturing him as a way to thank him (though he wouldn't admit it).
- Voice Actor: Diedrich Bader
Maboul is the father of Wadi and the chieftain of the Hassi who guard the Methuselah Tree (the source of all water on Earth). He disapproves of Wadi's kleptomaniac ways. In "Curse of the Stolen Tiger," he has the Saturdays babysit Wadi while he is away on Hassi business. He is good friends with Drew Saturday. He, Wadi, as well as some members of the Hassi took part in the fight against the cryptids controlled by V.V. Argost.
- Voice Actor: Liliana Mumy
Wadi is the daughter of Maboul and Zak's love interest. Wadi is a kleptomaniac, which her father disapproves of (even though after the events of "Eterno", she has vowed to recover stolen property). In "Eterno", she steals a salt crystal which inadvertently awakens the salt creature Eterno. She aids Zak in stopping it, building a love-hate friendship. She later assists the Saturdays in reclaiming a village's stolen blue tiger from Shoji Fuzen, Wadi helping to defeat him by stealing a component from Shoji's high-tech armor that controls its flight capability. All of Zak's family thought that he has a crush on her due to his being very clumsy around her (which turned out to be true), which he vehemently denies until she admits she thinks he's cute, which he immediately blushes at. She has a peculiar habit of stealing Zak's belt. In the episode "Life in The Underground", Wadi shows that she has a crush on Zak and gives him a kiss on the cheek she also copied his idea of "the claw" with a yo-yo shown in "Life in the Underground". Zak also has a crush on her that becomes more obvious in each episode she's there. She is around Zak's age (11-13).
Wadi participated alongside her tribe in "War Of The Cryptids" alongside the rest of the Hassi.
A skilled cryptid warrior, known for his devotion to catch his targets no matter what. Years ago he challenged Doc to a fight due to an accident caused by Zak which destroyed an archeological place guarded by him. In the ensuing fight Doc won but at the cost of a blinded eye and a scar on his face. As a token of honor Tsul 'Kalu gave him his amulet, a claw, which was to be used later on Zak's weapon. In the present he tracked Zak down, having learned that he is Kur and tried to reclaim the amulet, not wanting it to be used for evil purposes. After losing the battle against Zak he was able to see his true intentions and permitted Zak to use the power of the Claw. He is now an ally of the Saturdays and assisted in the fight against an army of cryptids. In 'And Your Enemies Closer', he helped keep Zak from getting killed by Argost and Munya. He fought and defeated Munya in 'War of the Cryptids.'
- Voice Actor: Candi Milo
A member of the Secret Scientists who is seen in "Eterno". She and the other scientists were at the meeting and discovered that the rivers have turned to salt in the Middle East of Arab. She and the other scientists helped Zak, Wadi, and Fiskerton to get the sap from the Methuselah Tree. Once they reached to the surface, Zak accidentally dropped the bottle (that had the sap) and some of the sap was destroying the salt bonds on Drew. Dr. Pachacutec shows Zak that the sap is breaking Drew's bonds. However, once Eterno quenches his thirst, his body crumbles to pieces of salt. Doc then saw the flower that uses to have the sap and said that he'll have Pachacutec analyze it. If the flower can by synthesize it, they might be able to reverse the effects of what Eterno did. Once the sap is synthesized and all of the people are free from their salt bonds, Dr. Pachacutec said that the scientists will deal with the waters that are still salt.
Dr. David Bara
- Voice Actor: Clancy Brown
A member of the Secret Scientists who is seen in "Shadows of Lemuria" and "And Your Enemies Closer".
In his first appearance, he uses his Dream-Time Totem to put Fiskerton to sleep in order to find the motivation behind his instinctual behavior. Argost sends a neaural parasite to control Fiskerton. After Drew told David to not let anyone in, she left, but Zak (who was controlled by the neural parasite) enters in and attacks. Dr. Bara tried to put him to sleep, but didn't prevailed. The parasite attaches on Fiskerton to control him, but Fiskerton was fighting back. An army of Fisk-Bots broke in (apparently created from Fiskerton's mind) and destroyed the Saturdays' headquarters. After Zak defeated the parasite, the Fisk-Bots used parts of the headquarters that resembles the globe of the diving rod. When the Saturdays head to Antarctica, David Bara said he'll find his way home.
In his second appearance, he was one of the scientists that are trying to capture a Revolving Beast.
- Voice Actor: Phil Morris
A member of the Secret Scientists who is specialized in anomalic weather.
In "The Kur Stone Part 2", he told Doc that Henry has been fatally wounded by the explosion (that was caused by Argost's firecracker beetles), but said that he'll be alright. He also believes that Argost is heading to Manaus, Brazil. He also suggested the Saturdays to leave Zak with him, while the rest of them get the last piece of the Kur Stone. This made Zak upset, but Doc suggested that Zak will stay with his family.
In "The King of Kumari Kandam", he called the Saturdays that the Kumari Kandam attacked him and his people somewhere at the South Indian Ocean.
In "Eterno", he was seen at the meeting with the other scientists.
- Voice Actor: Jessica DiCicco
Tiacapan (or simply known as Tica) is a young Mexican girl (around 11-12) who is seen in "The Thousand Eyes of Ahuizotl". Her village was terrorized by the monster known as Ahuizotl. She told the Saturdays that Ahuizotl is a nocturnal cryptid and steals the eyes from the living as if Ahuizotl is blind. She even explained that Ahuizotl was resting in its tomb, but awakens for unknown reasons after about 6 months passed. She also said that her people are using Miranda as a sacrifice to the beast, because they don't want Ahuizotl to steal theirs. Feeling bad that it's wrong to do it, Zak explains that people do a lot of things when they're scared. Tica also said there's still time before Miranda gets her eyes taken by the creature. She gives them masks to prevent the Ahuizotl from stealing their eyes. Once they reach to a pyramid, they find Miranda bound and gagged (and hanging upside down) with the Ahuizotl preparing to steal her eyes. Zak, however, uses his powers to battle the beast. He tells Tica to evacuate the villagers. Once Ahuizotl was defeated, the Saturdays decided to leave Miranda in Mexico, until Tica knows that they're all cleared.
- Voice Actors: Dee Bradley Baker (Honey Island Swamp Monster and Georgia Pigman), Uncredited (Lake Worth Monster)
A group of 13 hominid cryptids (consisting of Momo, Bishopville Lizard Man, the Honey Island Swamp Monster, Lake Worth Monster, Kinchafoonee Creep, Georgia Pigman, Bardin Booger, Man Cat, Devil Monkey, Green Goon, Hawley Him, Mississippi Swamp Ape, and the Fouke Monster) that have appeared in "Ghost in the Machine". They live on Honey Island, Louisiana and they seem to be based on the real-life reported ones (although some could be made up). They work for the deceased Basil Lancaster (a friend of Doc).
These cryptids attacked Zak, Komodo, and Fiskerton when they were wandering into the swamp and were nearly eaten by oversized alligators. They also attacked Drew and Doc in the lab, believing they were restarting the project. However, Zak, Komodo, and Fiskerton were captured by Dr. Lee and his scientists and mutated them into a cryptid known as the Saturday Hybrid/Zakermodo. When the cryptid hybrid (that looks like a cross between Zak, Fiskerton, and Komodo) escapes, the swamp cryptids begin to destroy the lab and Doc and Drew went after him. The Devil Monkey and the Fouke Monster were holding away Doc and Drew as Lake Worth Monster grabs the Zakermodo, until he heard Drew saying "Zak Saturday". The Lake Worth Monster releases the Saturday Hybrid, heads to one of the cabins and shows a picture of young Doc/Solomon with the deceased Dr. Basil Lancaster and a message (recorded in a radio) from Lancaster. Once Dr. Lee and the scientists are captured, the cryptids have left the machine to turn the cryptid hybrid back to Zak, Fiskerton, and Komodo. Soon, Zak, Fiskerton, and Komodo are back to normal. The Lake Worth Monster reveals the radio as Doc turns it on to hear the message from Lancaster.
The message reveals that Basil Lancaster and the other scientists created these cryptids. The cryptids were actually once human beings, but their DNA were mixed with animal DNA. Lancaster knew that what he did was wrong. He then betrayed Dr. Lee and destroyed enough research to cripple the project. The cryptids were saved by Lancaster and they went into hiding, but they'll be waiting to destroy the project. Honoring Dr. Lancaster's final request, the Saturdays and the cryptids destroy all that remained of the project.
In "War of the Cryptids", Zak uses one of the swamp cryptids as a soldier.
There were also toy figures of the Honey Island Swamp Monster (which is part of the Swamp Creature's Battleground), the Georgia Pigman, and the Bishopville Lizard Man.
A group of monks from the Himalayas. They were mentioned in "Van Rook's Apprentice" and make an actual appearance in "And Your Enemies Closer".
Drew mentioned that after she was separated from her family, the Tibetan monks found her and raised her in their temple. After she got older, the monks gave her a Tibetan Fire Sword.
In "And Your Enemies Closer", Doyle, Zon, and Van Rook visit the Himalayas and they find Drew. The monks arrived and welcomed Drew for returning to the Himalayas. In the temple, the monks were giving them tea. Van Rook was disgusted by the tea and asked how to say "taste like yak vomit" in Tibetan, resulting one of the monks to hit him on the head. Doyle was telling Drew that Argost and Munya have captured Baron Finster (which he knew that Finster knew about Argost's past), but wasn't sure why he abducted the Xing-Xing (which wasn't identified in the show and referred as an "old sasquatch thing"), but he knew it was also from the Himalayas.
When they went outside, Doyle knew the area where they lost their parents. Drew thought it was the storm, but it was actually a mysterious cryptid that killed them and pushing Doyle to the village. Doyle thought the Xing-Xing was the creature that attacked his parents. Drew told Doyle that they never knew that there was a cryptid in the Himalayas. The monks then looked at each other. Drew then got upset at them that they knew and never told her. The monks told her that they couldn't bare to add one more nightmare in her troubled sleep. They said that the cryptid is called the Yeti and her parents were not its only victims in those days. They said that they tried to hunt it down countless times, but when they finally found its lair, the beast was gone. They then showed Drew and the others to the Yeti's lair. Doyle was still upset about the "orange Yeti freak" for letting it go. However, one of the monks said that the Yeti doesn't have orange fur, but is pure white with pale blue skin and they suggested it was not the cryptid he saw.

A logger, who owns the Allegheny Mountains as his land. He's seen in "Food of the Giants". He and his three workers decided to make a city by cutting down trees, but one night, a large cryptid called the Allegewi attacks their campsite and abducts two of his workers. Harger called the Saturdays for help to search for his workers. He told Ruby to take the four-wheeler back to base camp and says to her that she'll be safe there. When the Saturdays were caught in strange traps, Harger showed up and also got caught. Abbey said that Harger caused the traps and having the weapons sabotaged. However, it's later revealed that Abbey was the culprit, who's working for Van Rook (who sold the land to Harger). When the Allegewi attacks and knocks out Abbey, it saw the Saturdays and Harger in the traps. It looked at Abbey's unconscious body and left her, believing she's dead at first.
When the Allegewi released the Saturdays out of the traps, Harger thought it was letting them go and not eating them. However, it's revealed that the Allegewi is a predatory thing and has to hunt its food. As the man-eating cryptid chases them (with Doyle carrying Abbey and Fiskerton carrying Zon as if her wings are injured), they climbed on a tree with Drew chopping it with her sword and they seemingly outran the Allegewi. They later cover mud on themselves to keep the cryptid from eating them. When Harger offered Doyle to rub mud on himself, Doyle refuses and "knows what he's made of and it's not the stuff". The Saturdays then found one of Harger's men, Wyatt. As Wyatt explained that Cody is missing, the Allegewi returns.
Later that night, the Saturdays were heading to the Allegewi's cave. While Harger was counting the "gorilla" and the "dino-bird" as one, it makes nine, which made Fiskerton and Zon (who's carried in a basket) yell at him and Zak warns him to count them separately as Harger agrees that it makes ten. As Doc and Doyle rescue Cody from the Allegewi, the three head outside with the cryptid chasing them. The group shoot catapults and spears at the Allegewi, which gives Fiskerton and Zon the chance to knock the Allegewi to a large net made of vines with Hickory sap (which was Zak's idea). When they planned to relocate the Allegewi to another location with plenty open land and zero human population (which Doyle didn't meant), Abbey frees it. As the Allegewi attacks, Abbey tells Doyle and Zak to tell their family that "she's sorry" as she pushes them out of the way and the Allegewi attacks her, causing her and the beast to fall into a chasm, but Abbey doesn't die. With the Allegewi defeated, Harger and his workers head back to their camp.
Ruby, Cody, and Wyatt
Three loggers, who work for Bud Harger. Two of the workers (Cody and Wyatt) were captured by an Allegewi. When Wyatt escaped from the beast's lair, he led the Saturdays to rescue Cody. When they reached the Allegewi's lair, the cryptid tries to catch Cody, who's hiding in a crevice. They managed to rescue him and defeat the Allegewi (thanks to Abbey, who lured it to a chasm).
Dr. Basil Lancaster
- Voice Actor: Fred Tatasciore
A scientist, who was a friend of Doc Saturday when he was young. He was seen in "Ghost in the Machine". He and Doc worked with Dr. Lee and three unnamed scientists with a machine to create cryptids on Honey Island Swamp. However, the project went out of control as the cryptids were mutated humans. He knew his conscience was wrong and it took too long to listen. Dr. Basil Lancaster betrayed Dr. Lee by destroying enough of their research to cripple the project, saved the cryptids and fled to the bayou. As his colleagues went into hiding, he left Honey Island and will know that the cryptids will destroy the project and the machine that created them. However, as years passed, Lancaster died. However, he did left Doc a message to reveal what Honey Island was really about.
Honoring Lancaster's final request, the Saturdays and the cryptids destroy all that remained of the project. Dr. Lee and the other three scientists are sent to prison by the US Army. Doc also takes the photo that shows a younger version of him and Lancaster. The message ends that Lancaster knows that Doc is a better man.
Villains and antagonists
- Voice Actor: Corey Burton
V.V. Argost is the series' main villain and the archenemy of the Saturdays. According to creator Jay Stevens, his full name is Vincent Vladislav Argost, after actor Vincent Price. He is the host of V.V. Argost's Weirdworld, a series that made him "the modern master of the bizarre" of the Earth. With knowledge of cryptids and being showy and dramatic, Argost's overall goal is the possession of Kur and the power it holds. Having hid his true nature well, Argost is actually a Yeti that had been attacking humans out of enjoyment in the Himalayas and taking items from their camp as souvenirs. According to Jay Stephens, one of the 'souvenirs' Argost had taken from a camp he had attacked was a television, from which he learned to speak English and resolves to live among humans by influencing them with a television show of his own. Donning a Megatooth shark skin cloak and mask, Argost lived on the streets before acquiring the funding he needs from Baron Finster in return for his scorpion lower body.
In "Kur Rising", Argost takes control of a creature he and the Saturdays believe to be Kur before the monster is defeated and he is taken to safety by Munya when his mask started to cracked after taking enough blows from Zak, revealed to be the host of the actual Kur. Throughout the second season, using Munya to give the Saturdays the notion that he had died, Argost when into hiding before saving Zak from Rani Nagi and offering to help him hone his Kur powers. However, as revealed in "Legion of Garuda", Argost possesses the flute of Gilgamesh with the intent to extract Zak's power while obtaining an orange ape-like cryptid from his past during the episode "Return of Tsul".
During the episode "And Your Enemies Closer", as Dolye and Drew eventually learn of his true nature and his role into their parents' death in the Himalayas, Argost kidnaps Zak and takes him to an island where he revealed that during the events of "Into The Mouth of Darkness" when he hacked into the Saturdays' airship computer in a search for a means to extract Zak's Kur powers, he learned about the existence of the Saturdays' evil counterparts, the Mondays. The research had Argost realize that Zak Monday is logically the Anti-Kur and stole the Smoke Mirror of Tezcatlipoca from the Paris museum to bring the anti-matter Zak into their reality to siphon the Anti-Kur into himself. Once the ritual is completed, now immune to Zak's powers, Argost destroys the relics to keep his new powers while revealing his true identity. Soon after, in series finale "War Of The Cryptids," Argost set his plans into motion, unleashing a gigantic cryptid army all over the Earth. However, his arrogance proves to be his undoing when he siphons Zak's powers in an attempt to amplify his own, having obtained an electronic sound-system that recreated a weaponized version of the Flute Of Gilgamesh. Unable to hear Zak's warning of the danger, Argost finds himself imploding from the two Kurs' energies and is presumed dead.
However, it is revealed that in the crossover episode "T.G.I.S" of Ben 10 Omniverse that Argost was actually thrown into a state of anti-matter flux from the Kur energies. But Argost had in place a back-up plan with Dr. Animo to be revived through the use of cryptid and alien DNA. But once revived, furious that Animo did it in three years rather after a month, Argost was initially displeased to find his body turned into a chimeric amalgamation. But Argost quickly finds his new body is to his advantage when he seeks revenge on Zak and is thrilled to learn that he still has the powers of the anti-matter Kur which allows him to control an entire army of mutant cryptids with a single thought. Ultimately he is defeated once again through the teamwork of Zak and Ben Tennyson, the later of whom manages to drain Argost's powers: effectively trapping him within his own body in a coma-like state.

Munya is V.V. Argost's silent and mysterious manservant. He has been injected with the DNA of a Papuan Giant Spider, enabling him to transform into a half-human/half-spider monster in battles. In this form, he gains superhuman strength, is able to climb walls, as well as can fire thick streams of webbing from his mouth. Following Argost's defeat at Antarctica, Munya wrapped up Argost in webbing and made off with him. In "Kur" Pt. 2, Munya was using a special typewriter called a "text to speech engine" to help promote V.V. Argost's return. After learning that Doyle was searching for his secrets, Argost had Munya hunt down every person who has to do with his past on orders, including Baron Finister. In the episode "And Your Enemies Closer", it was shown that Munya had enough cryptid DNA to be controlled by Zak. In "War of the Cryptids", Munya led an attack on Paris as part of Argost's army only to be defeated by Tsul 'Kalu, shortly after Argost's downfall. Munya is once again at his master's side upon he revival by Dr Animo and also confronts Zak when he discovers Animo's lair, but is defeated in the ensuing fight.

Once Zak's babysitter, Abbey Grey is an ancient civilization expert and Miranda Grey's sister. She appears in "The Kur Guardian", helping Zak, Doyle, and Fiskerton to learn about his Lemurian roots. She and Doyle begin dating at the end of the episode, only for him to discover in "Food of the Giants" that Van Rook hired her not long after Doyle quit. She admits her feelings for Doyle were real, but still intends to finish the Saturdays off. In "Kur Pt. 1", Leonidas Van Rook mentioned to Doyle that Abbey Grey took over his business. Later it's revealed that she is much better the field of mercenary work then Van Rook not only does she make more money but also is able to buy higher grade equipment due to her not being as much of a cheap skate as her former teacher. Also it's shown that she like her teacher has come under the employment of Argost.

Rani Nagi (Hindi for "queen of the Nagas") is a four-armed Naga and the queen of her race. She can control any type of snake (even Kumari Kandam's city-moving serpent) and speak through them. Her species is able to speak and breathe underwater.
When V.V. Argost captures Fiskerton, he calls her in to see if Fiskerton is Kur. She uses a relic forged from Kur's own essence which is said to glow in the presence of its master. When the artifact fails to glow, Argost asks her why the picture of Fiskerton was in Kur's tomb. She identifies him as a Lemurian, saying he can lead Argost to Kur. She then leaves before Doc charges in to face Argost. She later follows Zak, Doyle, Fiskerton, and Abby to Shangri-La in order to learn where Kur is located. After a brutal battle in which she mostly holds her own against the family, she is finally defeated by Fiskerton. She is seen later in "The Atlas Pin", where she is using her Kur-sensing relic around Kur's tomb, only for it to be stolen by Argost so he can use it to find Kur. She enlists the Saturdays' aid in retrieving her stolen relic, threatening to remove the Atlas Pin should they refuse to comply. Drew, Zak, and Komodo manage to stop her with help from Kumari Kandam, though she and her followers escapes capture. Doc, Doyle, Fiskerton, and Zon recovered the artifact. However, when Drew learned that the Nagas were dark mystics, she says the relic must be destroyed which Fiskerton does. However, Doyle covertly recovers the pieces and repairs it. The relic plays a big part in the 1st-season finale as it identifies Zak as Kur.
Rani Nagi and her fellow Nagas returned in the season two premiere "Kur" as the main villains. After it was revealed that Zak is Kur, the Nagas sought him out calling him their master. Rani attempted to convince Zak to tap into his inner nature and lead cryptids in a war against humanity. Her attempt was interrupted by the timely arrival of the rest of the family and after a rough battle, they saved Zak and escaped. However, the Nagas had already succeeded in having Zak's power summon the most vicious cryptids from around the planet in a battle against humans. She and the other Nagas lead it in the name of Kur. During the attack upon Manhattan, Rani Nagi was knocked away by V.V. Argost. Rani Nagi and her Nagas had possession of the Flute of Gilgamesh which Zak and Fiskerton stole. When Zak's life was threatened by Gokul using the Flute of Gilgamesh on him, she and her fellow Nagas helped the Saturdays and the scientists that were after Zak stop Gokul. In "War of the Cryptids," Rani Nagi and her Nagas side with V.V. Argost after he claims the Anti-Kur powers from Zak Monday. She was responsible for using Drew's sword to attack her only for Leonidas to sacrifice his life to block the attack. She was later knocked out by the Saturdays after V.V. Argost imploded.

He has above-average strength and durability, able to knock out Fiskerton with a single punch and survive a direct blast from Drew's fire sword (coupled with smashing through a wall from the impact) without injury. He attacks the Saturday household in order to devour Fiskerton, but is repelled by Zak using his mother's fire sword. In "Target: Fiskerton", he is hired by V.V. Argost to help Leonidas Van Rook capture Fiskerton. Pietro instead tries to eat Fiskerton during the conflict on the train, so Argost uses a neuroparasite to knock him unconscious.

Baron Finster is a half man/half robotic scorpion villain that Doyle once claimed to have fought. In his story, Doyle rescued a Ngani-vatu from him then rode the beast to safety. Doc calls the plausibility of the story into question and it seems likely that Doyle was exaggerating to entertain Zak. In "Cryptid vs Cryptid," Doyle later fought Baron Finster in the arctic and managed to defeat him and his henchmen, showing the villain at least exists. On the Viral website Ten Hero Tusk, there is an egg that was provided by Baron that shows that he is a Cryptozoologist like Van Rook. In "Into the Mouth of Darkness" Doyle and van Rook capture him to get information about Argost, but he is taken away by Munya. They did manage to find out Argost designed Baron Finster's robotic scorpion body in exchange for funding for Weird World as well as the fact that Argost was once a very poor man.
Jay Stephens has confirmed that V.V. Argost had Finster killed after Munya got Baron Finster away from Doyle and Van Rook.
The Mondays are the Saturdays' evil antimatter duplicates from a parallel universe, summoned by the Smoke Mirror of Tezcatlipoca. They are not well liked in their reality, most likely being criminals. Each Monday has a distinguishing characteristic that sets them apart from the Saturdays and cause reality to warp when in the presence of their duplicates. The name Monday was given to them by Zak Saturday, since according to him his double is a "less fun version of a Saturday", hence a Monday.
The Mondays accidentally banish themselves back to their own universe while fighting over the mirror. The Saturdays leave and fail to notice that Zak Monday and Komodo Monday escape from the mirror, leaving the others behind, even when Drew Monday purposely threatened her son even though he's out of sight and can't hear her. In "Paris is Melting", the evil Zak and Komodo attempt to threaten Zak into retrieving their airship from the antimatter universe following their attack on Dr. Cheechoo, Dr. Lawhorn, and Dr. Grimes. Zak recovers it for them, but makes a deal with the rest of the Monday family while doing so. Zak drains the ship's power with their help before returning, causing it to crash back into the repaired Smoke Mirror of Tezcatlipoca (which was on display in the Louvre) when the evil Zak and Komodo attempt to fly it. They are about to get beaten up by the family they left in the mirror. It is not known if whether or not Doyle has an evil counterpart like the rest of the Saturdays. It's most likely that Monday isn't really their last names, as Zak Monday had asked "Is that what you call us?" in "Paris is Melting", since technically, Zak (Saturday) made up the name. Zak Monday returned in 'And Your Enemies Closer', where Argost tricked him so he could steal his power with the Flute of Gilgamesh. Afterwards, Argost smashed both the flute and Smoke Mirror, trapping the other Mondays in their reality forever.

His hair color reversed from Zak Saturday's along with his eyes glowing green when using his power with his Fang weapon, Zak Monday possesses the Anti-Kur power and uses it to drive cryptids insane rather than calming them. While Zak Saturday respects life, Zak Monday disregards it and has shown to be sadistic. Out of the Monday's Zak Monday was the most reoccurring alongside Komodo Monday before they are sent back to their universe. However, in 'And Your Enemies Closer' when summoned back to his counterpart's reality in what he later learned was a trap, Zak Monday is killed off when Argost uses the Flute of Gilgamesh to absorb the Anti-Kur spirit from him.

Solomon "Doc" Monday's scarred eye is on the opposite side and he wears an eye patch over it. He usually speaks in incoherent babbling and has a much lower intellect than his counterpart. As shown in "Paris Is Melting", he has a power glove like Doc's, but it is gray and black, as well as fingerless and left-handed.
- Voice Actor: Nicole Sullivan
Drew Monday has a long, prehensile tongue, but is otherwise similar to her counterpart. She is more rationally scientific than her counterpart. Whereas Drew Saturday comes off as rough but loves Zak, Drew Monday acts sweetly and hates Zak (both of them). Her sword shoots ice instead of fire like her counterpart.
- Voice Actor: Diedrich Bader
Fiskerton Monday has horns in place of ears and is much more vicious than his counterpart. It is unknown if Fiskerton Monday is a Lemurian like his counterpart.
Komodo Monday is curiously capable of human speech and seems to be the leader of the group, when they're not fighting amongst themselves. He possesses black spots on his back which he can expand to cover his entire body and harden his skin.
- Voice Actor: Fred Tatasciore
Zon Monday has eye-like patterns on her wings, but otherwise behaves almost exactly like Zon Saturday.
Kur is an ancient Sumerian cryptid said to be a source of unlimited power and immortality for whoever can find and capture it, the first season focusing on it due to its ability to control all other cryptids which makes it a devastating threat in the wrong hands. The Saturdays and Argost are eventually led to Antarctica by Fiskerton, where they discover an ancient behemoth frozen in the ice. It has six snake-like heads and a total of twelve mouths (one on his face, one on each forearm, one for each of the snake-like heads and three on his chest). The creature also has two types of cryptids living in its body: large, ball-shaped furry cryptids and Dimetrodon-like cryptids that can attach to the monster's back and enable flight. Believing this was the creature he sought, Argost took control of the cryptid from the inside and commanded its army of cryptid parasites, forcing Zak and Fiskerton to follow him into it. While inside, Zak's powers seemed to be stronger than ever and after a lengthy battle, he used his supercharged powers to bring down the behemoth that was believed to be Kur.
However, the actual Kur is revealed to be Zak as a result of the mystic energies infused in Zak while he was in the womb. With added revelation that any attempt to remove the Kur spirit would kill him, Zak became targeted by various parties who would use his powers to their ends. One among them was Argost before he learned of Zak Monday and absorbed the Anti-Kur spirit, though Argost's greed got the better of them when he absorb the Kur spirit from Zak. Because the two Kur spirits are within one body, Argost implodes from the strain with the both spirits seemingly destroyed. However, as revealed in the Ben 10: Omniverse series, Argost was revealed to have been actually thrown into a state of anti-matter flux with Kur's powers eventually returning to Zak once the flux ends.

Eterno is the Salt Man that appears in "Eterno". He was once an ancient warrior king, whose thirst for conquest could not be quenched. He also attempts to find the Methuselah Tree (a tree that makes all the water on Earth). He, however, failed and was instead entombed in salt by the tree's protectors (which resemble giant purple centipedes and they cause an earthquake). After time passed, he became pure salt, but was awakened by water that touched him. After his awakening, he begins to turn the oceans into salt. Touching anything or anyone with his right hand will turn them to salt, but his left hand doesn't appear to have an effect. The Methuselah Tree is the only thing that is immune to his touch.
He turns the river of Middle East into salt and has trapped all of the villagers (which are the Hassi which are guardians of the Mother River, the supposed source of all the water on Earth) in shells of salt, including their Chief (Maboul). He also trapped Drew in a likewise salt shell. He makes a deal for Zak to get the sap from the tree and bring it to him and he'll turn everyone back to the way they were. He also tried to attack Zak, Wadi, and Fiskerton when they were searching for the tree, but left. Doc fought him for turning his wife into salt and Eterno turned his left leg into salt. Even when smashing Eterno into pieces, he forms himself back (saying he is eternal and Doc saying that nobody lives forever).
The tree's protectors arrived (with Zak controlling them) and he accidentally dropped a bottle that had the sap in it. Wadi also took one of the flowers from the tree and it made the protectors angry. Wadi throws it to Zak and he tries to get all of the victims turn back to normal, but Eterno turns the protectors to salt and snatches the flower from Zak and drinks the sap. Zak and Doc try to stop him, but it was too late. Eterno lets out a satisfied "Ah!" as his body crumbles into pieces of salt, his thirst finally quenched.

Ron Bantington is the head of Bantington Industrial who is seen in "Kur: Part 1". He was the biggest corporate sponsor of TV's Weird World, while also being involved in many illegal activities. Doyle tracked him down to a restaurant in London, England to see if Bantington knew any evidence of Argost. Bantington tells Doyle that he's a sponsor and apparently doesn't make the show. Doyle asked Baintington if he's trying to tell him that bad guys never really 'pal' around together. Ron said that he doesn't know where Argost has disappeared to, but wished he knew because Argost is his 'biggest money-maker' and said he knew one thing: his kind of people do like to 'pal' around together. He and his gang all tried to stop Doyle, but he and Zon managed to defeat him and his minions.

A magician from India who appears in "Legion of Garuda". He is possibly the leader of the Legion of Garuda. He can create illusions and summon images into the minds of his enemies. His group of people, long ago, performed a ritual that would defeat Kur. He lured the Saturdays by using an illusion of a young girl. He involves to help the Saturdays to destroy Kur if they could get the Flute of Gilgamesh from the Nagas. Once they got the flute and head to the ceremony, Gokul uses it and the flute begins to drain Zak's powers. However, it was revealed midway that driving Kur's spirit out of Zak will kill him, since he is Kur himself rather than someone possessed. Gokul tells them that Kur's powers were too great, angering the Saturdays (especially Drew). The Secret Scientists and the Nagas arrive to save him from being killed.
Gokul makes illusions of stone walls, but the Saturdays and the Scientists knew it was illusions, but it is mixed with both reality and illusion, but Deadbolt can tell the difference. Once Deadbolt makes through the maze, he tries to save Zak, but Gokul destroys him by throwing a large spear. Gokul then creates an illusion of a gigantic hawk that scares the Nagas away, but Rani Nagi doesn't flee away. Gokul then creates an illusion of fire, but the Saturdays, the Scientists, and Rani Nagi save Zak from being killed. Gokul then gives up and escapes.

An overweight man, who is the biggest illegal cryptid trader on the Earth. He just appears in "The Return of Tsul Kalu". Baron Finster told Doyle, Van Rook, and Zon to follow the cryptids. Doyle, Van Rook, and Zon tracked him at Black Market, Morocco to see if he knows anything about Argost's past. Once the guards were defeated, they find several cryptids in cages and tanks (Zon was interested to eating the aquatic sea scorpion-like cryptids).
Grosshomme was in his office (with three cryptids) and having some "exquisite" dumplings. Van Rook and Doyle caught him. Once Doyle tried one of the dumplings, he said it tasted good and asked what it was made of. Abbey arrived and tells him that the dumplings were made out of a panda bear. Doyle spat the dumpling out and yells at Grosshomme for eating something made out of an endangered animal. While Grosshomme was eating more his dumplings, Argost and Munya arrived and Grosshomme becomes terrified (even when Abbey said she could deliver him). Zon arrives and attacks Argost, Munya, and Abbey and Doyle creates a cloud of smoke from his jetpack.
Doyle and Van Rook tell Grosshomme to come with them if he wants to live and tells them if he knows about Argost's past. However, three cryptids escaped and Grosshomme forced Doyle to take them with him because they're apparently worth a fortune. While they were hiding, Grosshomme was eating a kabob and the fish cryptid escaped. Once Doyle defeats Abbey and gets the fish cryptid back, he sees Zon and Van Rook fighting Munya and Grosshomme was on a roof of a building with the two primate cryptids and Argost was about to take one of them, but Doyle kicks Argost off the roof. Doyle tells Grosshomme to quit playing "zookeeper" and tells him to set the cryptids loose if he wants to eat another kabob. Grosshomme then releases them. Doyle then tells Van Rook and Zon to fly Grosshomme to safety and he hold off Argost. As Zon and Van Rook quickly fly Grosshomme to safety, Argost's actual target is the orange primate cryptid.

A villainous scientist, who is a colleague of Basil Lancaster and young Doc Saturday in a project to create cryptids within Honey Island Swamp. When the project went out of control, Dr. Lancaster betrayed him and the other three scientists by destroying enough of their research to cripple the project, saved the cryptids and fled to the bayou. Years later, they use a technology to create a ghost of the late Basil Lancaster to lure the Saturdays to Honey Island Swamp and use "Basil's ghost" to make Doc restart the project. Dr. Lee and his men knock out Zak, Fiskerton, and Komodo with sleeping gas and abduct them. They place them in a machine to mutate them. Once the machine was activated, the three Saturdays morph together into a monstrous cryptid, the Zakermodo/Saturday Hybrid.
When Doc and Drew confronted Dr. Lee and his men, they revealed that they turned their boys into a cryptid. Drew tried to get their attention, but Dr. Lee explained that there are three brains in one head, trying to work together and it makes them confused. Doc grabs Dr. Lee and threatens him with his glove and tells him to fix his dirty work. Dr. Lee said he would if Doc will agree to continue the project. However, the two refused and Drew said that they will figure out the machine, but Doc told Drew if the machine gets damaged, the boys could be stuck that way forever. Soon, the 13 cryptids, that were created by the machine years ago, arrive when they hear the Zakermodo screaming and destroy the machine. Dr. Lee becomes frightened and ordered the cryptids to stay away, since he and the other scientists made them and told them to obey him. However, the cryptids would not listen and the Zakermodo breaks free. When Doc and Drew head to the swamp to catch him, four of the cryptids pull the two away as the Lake Worth Monster grabs the Saturday Hybrid, believing he's one of them. However, when the cryptid heard Drew calling out her son's name, he releases him, heads to one of the cabins and reveals a photo of young Doc and Dr. Lancaster and a message recorded in a radio.
When the Saturdays and the cryptids head back to the lab, the machine wasn't damaged. Dr. Lee was forced to turn the Saturday Hybrid back to normal. After the boys returned to normal and hearing the message from Lancaster, the Saturdays and the cryptids destroy the machine and all that remain of the project. Dr. Lee and the three scientists were sent to prison by the US Army.
