Zetman (ゼットマン Zettoman ) is a manga series by Masakazu Katsura. The series started as a one-shot in a series of four published in Weekly Shōnen Jump between 1989 and 1994, and collected into a tankōbon released in 1995. A more mature and full-fledged series started in Weekly Young Jump in 2002. Zetman has been adapted into an anime series that premiered on April 2, 2012.
The story starts off with a face-off between two rival heroes, ZET and Alphasz, and then traces their origins – Jin Kanzaki, a young man with the ability to transform into a superhuman being known as ZET, and Kouga Amagi, a young man with a strong sense of justice who uses technology to fight as Alphasz.
The fates of these two men and those around them intertwine as they fight to protect mankind and destroy monstrous abominations known as Players, who ironically are the creations of the Amagi Corporation, the company founded by Kouga's grandfather, Mitsugai Amagi.
Jin's family 
Jin Kanzaki/ZET 
Jin Kanzaki (神崎 人 Kanzaki Jin ). The main protagonist. A mysterious young man bearing a circular lump on the back of his left hand, Jin was a result of the Z.E.T. Project by the Amagi Corporation to create the perfect being to fight and destroy the escaped Players. He was however released by Gorou Kanzaki, who wanted nothing more for Jin than to grow up as a normal human. After the death of his 'grandfather', Kanzaki, Jin stayed with Akemi Kawakami until he witnessed her 'death' under the hands of the Amagi Corp., in an effort to retrieve their creation. He has been living in a slum alone ever since, monitored closely by his creators, especially Mitsugai. One day, he meets Hanako in the slums. After inviting her to live with him and saving her life on two occasions, he begins to have feelings for her; evident when he swears to protect her with all his might, followed by making love to her afterwards. He even starts calling Hanako his girlfriend. After the Amagi mansion is destroyed, he goes into hiding along with Kouga and Konoha, Mei, Shimura, Hanae and the two black suits until Kouga has Seizou clear him of all charges. While on a date with Hanako, he is attacked by the Sweeper, transforms in front of Hanako and blacks out, leading him to believe either he or the Sweeper killed her. Believing that, he thinks his life is now meaningless, and as soon as he gets the enhanced gum, he goes off on a suicide mission against EVOL.
Jin is able to transform a creature known as "ZET", a mutant possessing superhuman abilities, but often mistaken for another Player. The transformation is slow, though it may be accelerated due to extreme rage and conditions. He had lost this ability briefly, but regained it with the use of a special gum (Chapter 67). He later has a ceramic stake put in his heart by Seiji, thus allowing him to transform without the gum into "White" ZET(Chapter 102). It is later revealed by Hanae that the pendant his grandfather gave him has the ability to transform Jin into the "True ZET." The source of his strength appears to be the mysterious lump on his hand. After a Jin clone injected him with a formula that reacts badly with his gum, he has been having blackouts, not remembering what happened after a period of time. After his latest encounter with the Sweeper, he asks Hanae to create a stronger version of the gum, which transforms him into "White" ZET. He then learns of Seiji's plan to attack Amagi Corp., so he and the two black suits go to stop him. While there, they manage to kill the second Chameleon Player and a swarm of Corpse Riders (the latter with the help of Oyama), but he is overpowered by the Knight Player. Jin attempted to get the Knight Player to betray Haitani after the effects of the gum wore off, but failed and became unconscious as Kouga/Alphasz came to the rescue. He gained consciousness in time to stop Kouga from inserting the "Crimson Stake" into Jin's chest (which would turn Jin into the "True ZET"), saying that it was exactly what Haitani wants to happen. Soon afterwards, he blacks out again and finds himself surrounded by destruction, supposedly by his hand.
The design of ZET was based on an anime character created by Amagi Corp.
Gorou Kanzaki 
Voiced by: Mitsuo Senda (Japanese), Adam Nevel (English)
Kanzaki Gorō (神崎 悟郎). A pioneer in both the N.E.T. and Z.E.T. Projects in the Amagi Corporation, Kanzaki escaped with an infant Jin in defiance to turning his 'child' into a killing machine. Later disguised himself as a homeless old man and posed as the grandfather of the growing Jin. Was killed in a bid to protect Jin from an awakened Player.
Kanzaki's head was however retrieved by the Amagi Corp. and hooked up to a computer so as to obtain unknown information about ZET/Jin. Their efforts were in vain however when a crying Jin, unable to bear seeing his grandfather in such a state, pulled off the life support plug, with Kanzaki asking Jin if he had been taking his meals regularly as a final greeting. However, it was revealed that Mitsuagi had the life support plug put back in. His head was then stolen two years later by the second Chameleon Player, with the intentions of cracking the secrets within his head.
He managed to make Jin lose his powers of ZET by tricking Mitsugai, but it was brief when the Amagi Corp. came up with a gum which allowed Jin access to his original abilities.
Akemi Kawakami 
Kawakami Akemi (川上 明美). The foster parent to Jin after Kanzaki. Always addressed as 'Oba-chan/old lady/auntie' by Jin, Akemi was an ex-hostess who had a son she lost custody of to her ex-husband. Her face was slashed by a crazed client, who in turn suffered near fatal injuries by a young Jin, having recalled how his grandfather was killed. She has been selling crepes at a roadside stall ever since.
She was seemingly killed right in front of Jin's eyes in a bid to let Jin return to the Amagi Corp., but was later revealed by Mitsugai to be alive, and was given back custody of her son with the help of Amagi Corp. She received a box of money saved by Jin as a parting gift. Two years later, she came at Jin's request to give him back his grandfather's pendant.
Amagi family 
Kouga Amagi/Alphasz 
Amagi Kōga (天城 高雅, or コウガ Kouga). Konoha's older brother, and grandson of Mitsugai Amagi. Both academically and sports-inclined, especially soccer. However, although he is popular with girls, he doesn't really know how to act around them, and Jin says he is "so honest, it hurts." Due to his attraction to an anime 'Ginga Choujin Alphasz', Kouga has developed a strong sense of justice since young. Urged by his encounter with Jin during a fire accident (caused by a Player) to become a hero of justice. He had been depending on a trio of researchers since middle school for gadgets which could assist him in his escapades. He lost his right forearm during his captivity by Jirou Nakata, together with his sense of justice. After he managed to save Mayu, he is fitted with a smart prosthetic arm (eventually revealed by Hayami to have a tracking system in it), and is required to undergo several months of rehabilitation.
During this time, Kouga regains his composure and is dating Mayu. After learning about the Players and his grandfather's involvement in the project, he initiates the Alphasz Project with the Trio, who created a high-performance combat body suit resembling Kouga's childhood hero, complete with high-tech weaponry and gadgets, to combat his grandfather's creations. However, his Alphasz suit isn't strong enough to help him take on Souya, as he learned the hard way. He is very protective of his family, especially his sister, Konoha. In his first battle as Alphasz, he teams up with Jin/ZET to defeat the Shrimp EVOL, and discovers Jin's identity as ZET. He then tells Jin that he is currently the best hope the world has of defeating the players, and that he will strive to catch up to him. After Hayami attempted to capture Jin, he goes into hiding along with Konoha, Jin, Mei, Shimura, Hanae, and the two black suits until Kouga manages to convince his father to clear Jin of all charges, though Seizou warns Kouga not to trust Jin. During the assault on Amagi Corp., he is captured and detained by Hayami. Hayami then proceeds to inject Kouga with a bug created by the clone of Ichirou, which would bring his body to perform superhuman abilities. However, as soon as the bug wears out, his body will be left in a crippled state, something Hayami is fine with. As soon as he regains consciousness, he enters his Alphasz suit and uses both his newly acquired powers and his weapons to defeat the Knight Player. During his conversation with Haitani afterwards, he reveals that if Jin becomes the monster he swore to destroy, he would kill him himself. In response, Haitani gives him the "Crimson Stake" to place into Jin's chest, in order to become the true ZET and to see if Jin can remain himself. However, before he can place the stake into Jin's chest, Jin stopped him, telling him this is exactly what Haitani wants to happen. It is currently unknown what happened to Kouga after Jin experienced another blackout.
Konoha Amagi 
Amagi Konoha (天城 小葉). Sister to Kouga and granddaughter of Mitsugai. She bears a distinct dislike to her grandfather due to childhood trauma. Konoha first met Jin during her secret volunteer work with her mother when they were still small, and has been harboring feeling for him ever since. Addressed Jin as 'Tenshi-kun/Mr. Angel' after seeing him fall from the sky to her aid when she was bullied by a group of hooligans, and only learns Jin's name after. When she saw Jin emerge from the building destroyed by the Fire Player and see him faint, she picks up his grandfather's pendant, which she continued to hold onto until the Jin clones stole it from her during the assault on Amagi manor.
She is unaware of Jin being ZET, nor of her family's involvement with the Players. She was recently involved in a life-threatening attack by the Ebizou/Shrimp EVOL, an incident that she retains the memories of due to Kouga's refusing of mind-wiping her. After Hayami attempted to capture Jin, she and Kouga went into hiding along with Jin, Shimura, Mei, Hanae, and the two black suits, until Kouga has Jin cleared of all charges. Soon afterwards, she and her mother are kidnapped by Suzuki and used as hostages during Seiji's attack on Amagi Corp.
Mitsugai Amagi 
Amagi Mitsugai (天城 光鎧). Founder of, and ex-CEO of the Amagi Corporation who believed in a distinct divide between the rich and the poor.
In the pursuit of his dream to create the perfect artificial humans, he initiated the N.E.T. Project, but it eventually led to the escape of his creations, named 'Players'. Having a heavy sense of responsibility for the incident, Mitsugai then commenced Project Z.E.T. to set things right, though once again his plans were foiled by the betrayal of Kanzaki. He then became hell-bent on retrieving ZET back after countless failures to create a new one.
Mitsugai's methods were often hard-handed, but after the destruction of his laboratory a second time by Players, he seems to have softened up, now giving Jin a choice of either becoming ZET or living as a normal human, though it is unknown if this is just a facade or not. He has also agreed to help Kouga in any way he can. After he finds Shibaki, he once again attempts to convince Jin to become the "true" ZET. However, during the clone Jin's assault on Mitsuagi's third secret laboratory and the Amagi mansion, he is left injured and is forced to recuperate at Amagi Corp.

Amagi Seizou (天城 清造). Son of Mitsugai, and father to Kouga and Konoha. Current CEO of the Amagi Corporation. Was named to be one of the masterminds of the Player Project by Jirou, but he feigns ignorance to all the various secret Projects under Amagi Corp.. After the Amagi mansion is destroyed, he orders Jin to be arrested, forcing Jin and his friends into hiding. He soon reveals that he knows Hayami was behind the Jirou inciden, and had him put in a vegetative state. When Kouga explained the situation with Jin to him, he had Jin cleared of all charges. However, he warns Kouga not to trust Jin, as he may join EVOL. It is then revealed by Seiji that Seizou is funding EVOL, and during the attack on Amagi Corp., he was also funding human experiments, which took the lives of the wife and son of Suzuki ("Katou").
Youko Amagi 
Voiced by: Aya Hisakawa (Japanese), Cricket Brown (English)
Amagi Yōko (天城 葉子). Seizou's wife, and mother to Kouga and Konoha. Was chastised by Mitsugai for doing volunteer work in secret, resulting in Konoha's childhood trauma. She then ran away from home while continuing her volunteer work, and never returned since. However, she and Seizou are not officially divorced yet. It is eventually revealed that she has been staying at the home of her lover, Suzuki. She and Konoha are soon kidnapped by Seiji and Suzuki, the latter revealing that Seizou funded human experiments of his wife and his son, Katou. Soon afterwards, Amagi Tower starts to be destroyed, and in the chaos, she is seen falling into an inferno, but was saved by Suzuki.
Supporting characters 
The Trio 
A trio of scientists allied with Kouga, they are responsible for making the gadgets he uses in battle. No matter what happens, they fully support Kouga and actions. So far, only one of their names have been given (Shimura). Two years after the incident with Jirou, they create a body suit similar to "Ginga Choujin Alphasz" at Kouga's request, so he could truly become a super hero. After Hayami tried to capture Jin, Shimura went into hiding with Kouga, Konoha, Jin, Mei, the two black suits, and Hanae, until Kouga has Jin cleared of all charges. During the attack on Amagi Corp., one of the trio is shot, but not killed, by Hayami.
Hayami (早見). An executive in Amagi Corp. and assistant to Seizou, he supports Kouga's actions as Alphasz to the fullest, though it was revealed that he only did it to distance Kouga from taking over Amagi Corp.. However, Kouga's way of thinking as Alphasz always tends to give him a headache when they mess up his plans. After the incident with Jirou, he told Seizou that they should allow Mayu to live, as she was the only person Kouga was able to save, serving as a "trophy" of his success. However, he agreed to have her memories of the incident erased. When the Amagi mansion was blown up, he was ordered by Seizou to arrest Jin, to which he agrees to. However, he and the strike force he brought with him were quickly, but non-fatally, dispatched by a semi-transformed Jin. Soon afterwards, it was believed by Seizou that under the alias of "Katou," Hayami plotted the Amagi clan's downfall leading to the incident with Jirou. Seizou then used a machine to search Hayami's memories to prove this, leaving Hayami in a vegetative state. However, he was brought back by an unknown individual, revealing to Kouga that though he isn't "Katou," he was in league with him in a plan to bring down the Amagi clan, which would allow Hayami to take position as the new C.E.O. of Amagi Corp.. Soon after his revelation to Kouga, he injects him with one of the insects made by a clone of Ichirou, in order for Kouga's body to reach superhuman levels and help him achieve his agenda. Afterwards, he, Seiji and Suzuki ("Katou") launched a terrorist attack on a New Year's Eve party that Seizou was hosting, in an attempt to make Seizou confess to all the injustices that he committed on film. However, one of the hostages tries to grab a machine gun from one of the underlings, and in the chaos, Hayami is shot in the chest and seemingly killed.
Jirou Nakata 
(Nakata Jiro). The father of Ichirou, he is a former scientist of Amagi Corp. and an expert in researching the creation of the Players. He admits that the only people he ever cared for were his wife and son, and was devastated when he witnessed his son's murder. When he discovered that the Players were to be used as a means of entertainment, he spoke out against the idea to Kabe, and was sealed inside his underground laboratory soon after, along with the corpse of his son. He soon revived Ichirou by turning him into a Player, and the two survived in the laboratory for sixteen years on nothing but water and medications. When they were set free, he began to plot his revenge against Amagi Corp. along with Ichirou and Katou, a greedy Amagi employee. He then set his sights on vengeance through Kouga, under the pretense of helping him become a better hero through tests meant to make Kouga abandon his emotions and make decisions based on cold, hard logic. However, because Kouga refused to abandon his ideals, he managed to "fail" every single test, ending with innocent people getting killed. When he brought Kouga and many of his fangirls to his base, he proceeded to kill the fans when Kouga failed his tests, until only Mayu remained. After trying to coerce Kouga to join his side by telling him about Mitsuagi's involvement with the Player's creation, a man working for "Katou" arrived and proceeded to shoot him and attempt to use footage obtained throughout the building to ruin the Amagi family's name. When Ichirou set the building to self-destruct, he killed "Katou's" assassin and attempted to kill Mayu and Kouga, but was stopped by Ichirou's powers. Ichirou then used his powers to make his father, to his dismay, shoot him in the head. As Jirou laid dying next to his son, he believes he will go to Hell, but due to images he saw before his death (ex. what would happen if Ichirou wasn't run over) it is believed he went to Heaven with his son, thus dies happy.
Mayu Hashimoto 
(Hashimoto Mayu). A teenage girl who is a fan of Kouga's. She had a history of prostitution. She and many other women were invited to a "party hosted by Kouga," but created by Jirou Nakata as a way of bringing Kouga to his side. During the party, all the other girls were killed, but before she could be killed by the Kouga clones, she was rescued by Ichirou, who couldn't stand by and let his father kill any more innocent people. While trying to escape with Kouga, she was shot by Jirou, though survived due to a makeshift bulletproof vest created by Kouga. After they escaped, her memory of the incident was erased by Amagi Corp.. Two years after the event, she and Kouga are dating, though she considers herself unworthy of him, due to her past of prostitution. When she was on a Christmas Eve date with Kouga, she tried to have sex with him. However, Kouga's memories of the incident with Jirou prevented him from doing so, devastating Mayu.
Black Suits A and B 
(Kuro no soroi A to B). Two of Mitsuagi's bodyguards, they know everything about the Players, EVOL, and ZET. When they first appeared, they escorted Jin to Mitsuagi's second secret laboratory, in an attempt for Mitsuagi to convince Jin to become ZET. Two years later, when Jin decided to become ZET, they escorted him and Mitsuagi back to the lab only to find it completely wrecked by the second Chameleon Player and Saitou/Rhino Player. While in the lab, A had his arm injured, and B lost his right eye protecting Prof. Kishimoto from the second Chameleon Player. They returned in Mitsuagi's third secret laboratory, where they received their nicknames from Jin. After the laboratory and Amagi mansion were attacked and destroyed by clones of Jin, but they managed to escape with Mitsuagi. When confronted by Hayami about Jin, they stood up for him, showing they see Jin as a friend. After Hayami's attempt to arrest Jin, they went into hiding along with Jin, Kouga, Konoha, Mei, Shimura, and Hanae, until Kouga managed to clear Jin's name. Soon afterwards, Jin tells the black suits of Seiji's plan against Amagi Corp., so they join him to stop Seiji and protect a still recovering Mitsuagi. While there, they run into the second Chameleon Player, and after Jin manages to expose the Player's heart, black suit B takes vengeance against the Player's murder of Kishimoto by shooting him in the heart, with Sanae listening over the phone. The two black suits, accompanied by Oyama, then fight their way through a swarm of Seiji' "Corpse Riders", leaving Jin to deal with the Knight Player. They then proceed to rescue the hostages as Haitani starts to destroy Amagi Tower, and start to find a way to escape the building.
Professor Kishimoto 
(Kishimoto Kyokan). A scientist working with Mitsuagi to transform Jin into ZET. When the second Chameleon Player and Saitou/Rhino Player assaulted the second laboratory, the second Chameleon Player attempted to make him open the container of Kanzaki's head, but due to the interference of black suit B and Kishimoto resisting, he ended up getting killed by him. It is later revealed by Hanae that he was engaged to her. During the attack on Amagi Corp., his murder was avenged by black suit B.
(Oyama). The chief of police, he does his best to protect Jin. When Jin was taken in for questioning about his defending of Akemi, he told Jin to keep his head up and move forward, something that has stuck with Jin for years to come. During the assault on Amagi Corp. (where he happened to be at the time), he joined up with Jin and the two black suits and fought through a swarm of Seiji's Corpse Riders. Afterwards, he discovered Jin's identity as ZET when he defended the three from the Knight Player, but he firmly believes that Jin is a true human, something the two black suits respect.
Hanako Tanaka 
(Tanaka Hanako). A tomboyish teenage girl. She has had constant headaches since she was born, leading her to go to the nurse's office quite often as a result. Because of this, students thought she was just slacking off, and was bullied by them, leaving her traumatized and unwilling to go to high school. After this, her parents started becoming apathetic to her, forcing her to run away. She met Jin as he was living in the slum she ran away to. When Jin saved her from the homicidal Crab Player, she was offered to live with him and become a family with him. She then quickly developed romantic feelings for him. She was later nearly raped by the Cockroach Player, but was saved by the combination of a call from the Shrimp Player and a group of Sweepers. When she was asked by Jin if she wanted to live away from him, she broke down crying, but was comforted by Jin telling her that he will protect her if she decides to stay, which she does. Soon after, Jin seems to reciprocate her feelings for him when she has sex with him. However, Jin convinces her to go home the next day, at least until he can get them their own home. Before she leaves, she texts her full name to Jin, and he goes on to call her Hanako, even though she hates being called that. While on a Christmas Eve date with Jin, the Sweeper attacked Jin, causing him to transform in front of her, leaving her terrified. Because he blacked out, Jin believes that either the Sweeper killed her, or he did it himself. It is revealed that after the attack on Jin, she was kidnapped by Seiji and kept as a hostage in the attack on Amagi Corp.. During a conversation with Seiji, she reveals that she still loves Jin, even if he is ZET. In chapter 189, after the full transformation of ZET, we see her kneeling near a G3 waiting to be killed by him.
(Shibaki). One of the scientists working on the Z.E.T. project along with Kanzaki. He was eventaully captured by the second Chameleon Player during the raid on Mitsyuagi's second laboratory. He was soon put to work as a slave at EVOL's headquarters, along with his daughter, Mei, until he learned of EVOL's true intentions. When he arrived at Mitsuagi's third secret laboratory, he tried to tell Jin all he could about his past and about ZET, but was taken over by a small Player insect and forced to commit suicide. After his death, Sanae used a machine to read his brain for information on transforming Jin into the "True" ZET, also finding a final message he had for Jin, a message he has yet to listen to.
(Mei). A unique Player and the daughter of Shibaki. Usually quiet, reserved, and with a childlike personality, she has a strange bodily composition which requires her to take medications every three hours, or else she will dissolve. After her father was forced into committing suicide, Jin decided to protect her, a kindness she repays by saving Jin from an incomplete clone of him. After Hayami tried to capture Jin, she went into hiding with him, along with Kouga, Konoha, Hanae, the two black suits, and Shimura.
Hanae Sanada 
(Sanada Hanae). A female scientist and former fiance to the late Professor Kishimoto. Although they never got the chance to marry, she insists that others address her as Kishimoto. She first appeared in Mitsuagi's third secret laboratory, where she was helping to try to transform Jin into ZET. When Shibaki was forced into suicide, she used a device to read his brain to find out info on EVOL and how to transform Jin into the "True ZET." After the assault on the Amagi mansion, she went to go into hiding along with Jin, Kouga, Konoha, Mei, Shimura, and the two black suits until Kouga has Jin cleared of all charges. She then creates a stronger version of Jin's gum at his own request, which she says will transform him as far as "White" ZET. After Jin/ZET grievously injures the second Chameleon Player, black suit B calls her and lets her listen as he kills the Player, thus avenging Kishimoto.
(Suzuki). A friend of Jin's and Youko's lover. After Youko ran away, she went to live with him, where they continued to help the homeless. After Jin was nearly captured, he offers him and those with him sanctuary. Soon afterwards, it is revealed that he is working with Seiji, and the two of them kidnap Konoha and Youko. During Seiji's planned attack on Amagi Corp., he reveals to Seizou, Youko and Konoha that Seizou's funding of human experiments cost him the lives of his wife and his son, Katou. Thus, he reveals that he was "Katou," the mastermind behind the incident with Jirou.
Creatures that were created as an intent to create perfect artificial humans. The project became more than just to create the perfect artificial human, it became more of a hobby for the rich men to bet on them, gambling as they were pitted against other monsters to fight. It went on until the players finally gained awareness and killed off everyone in sight. Because of this, many players feel that humans mistreated them and that they are far superior and deserve better. It is revealed that Seiji has a formula to produce Corpse Riders, Player-like beings created from the corpses of recently deceased humans. Corpse Riders aren't as strong as Players, but they possess strength in numbers.
Chameleon Player #1 
The first Player introduced in the series, he is modeled after a chameleon. While he was still human, he tried to commit suicide after killing everyone in the shantytown Jin and Gorou were living in, but was rescued by Jin. Afterwards, he reverted and tried to kill him, but died fighting Kanzaki's and slicing off his arm.
Fire Player 
The second Player to appear. Originally a building manager, he became known in the media as an arsonist. As a Player, he can generate, control, and heal wounds from fire. When he fought Jin, he impaled him through the gut, allowing him to begin his first transformation into a preliminary ZET, and was killed by him.
Ichirou Nakata 
The third Player to appear. Originally a human child, Ichiro was the son of Jiro Nakata. He and his mother were the only ones that Jiro has ever cared for. He was murdered in a hit and run, and his corpse was placed in the sealed laboratory with his father for sixteen years. While trapped, Jiro revived him by being turning him into a player. When they were freed, the sudden exposure to sunlight mutated his body into an insect/humanoid form. His father eventually decides to take revenge against Amagi Corp. through Kouga, but after realizing his father is evil, he rebels by using his power to rescue Mayu from the Kouga doubles and setting their laboratory to self-destruct. As the laboratory was falling apart, he used his powers to take control of his father and commit assisted suicide, not wanting his powers to be used to kill any more innocent people. It is implied that he and his father both went to heaven when they died. During the assault on Amagi Corp., Hayami reveals that he created an exact clone of Ichirou, intending to use his power to enhance Kouga's body.
As a player, he is capable of using a special kind of bug to take control of people, and make them say what he wants. This power also allows him to "read" the hearts of those he controls.
Saitou/Rhino Player 
The fourth Player to appear. He is modeled after a rhinoceros, and like his animal counterpart, he has immense strength. He and the Chameleon Player broke into Mitsuagi's secret facility to steal Kanzaki's still-functioning head to unlock its secrets. During his fight with Jin, his horn was impaled into Jin's chest, allowing him to transform into a semi-complete Zet and kill him.
Chameleon Player #2 
The fifth Player to appear. He is also modeled after a chameleon. Like a chameleon, he can blend into the background by turning invisible, and can also use his tongue as a deadly weapon. He and Saitou/Rhino Player broke into Mitsuagi's secret facility to steal Kanzaki's still functioning head to unlock its secrets. He managed to succeed and escape with his life. He appears again during the attack on Amagi Corp., with the intent to kill Jin/ZET and the two black suits. However, Jin/ZET is able to grievously wound the Player, leaving his heart exposed. Black suit B uses this opportunity to kill the Player, thus avenging Kishimoto's murder.
Kanizou/Crab Player 
The sixth Player to appear, he is modeled after a crab. He views humanity as a filth that needs to be washed away. When he tried to kill Tanaka, Jin jumped in and fought him, using his ZET powers to destroy his main body. He was killed for good by the Sweeper. As a Player, he can emit a foam that can dissolve anyone, and can detach himself from his body.
Gokizou/Cockroach Player 
The seventh Player to appear, he is modeled after a cockroach. The twin brother of Ebizou/Shrimp Player, he tends to act without thinking. Under Seiji's orders, he and his brother tried to kill Jin.

As a Player, he can create and switch to a new body if his previous one is killed, as well as create cockroach-like spawn.
Ebizou/Shrimp Player 
The eighth Player to appear, he is modeled after a shrimp. Although he is the twin brother of the Cockroach Player, unlike his brother, he keeps a cool head and thinks things through. He and his brother tried to kill Jin under Seiji's orders. He kidnapped Konoha and her friend in an attempt to kill Jin, but was delayed by the help of Jin's neighbors and Kouga/Alphasz.

While trying to capture him, his left wing was sliced of by Kouga/Alphasz, who had just gained a flight system in his armor. However, he managed to escape with his life when Souya quickly beat Kouga/Alphasz into unconsciousness.
Snake Player 
The tenth Player to appear, he is presumably modeled after a cobra. He appeared while Jin and Kouga were each on a date with Hanako and Mayu, respectively. When Seiji made his declaration of war, he and many other Players went on a murderous rampage, which lasted until Seiji blew up the area, killing all the humans and Players there (except Kouga/Alphasz).
Knight Player 
The eleventh Player to appear, he is modeled after a knight, complete with a sword. He also tends to speak like a knight, using words like "tomfoolery" and "poppycock" in his speech. As a Player, he is able to move at superhuman speed. He serves Seiji, and follows him to his attack on Amagi Corp. During the attack, he challenges Jin/ZET head on, but proves to be stronger than Jin in his "White" ZET form. During the fight, he admits that he wanted an excuse to kill Jin as ZET so Seiji would acknowledge him. However, though he loaly serves Seiji, he states that he won't hesitate to kill him should he turn on the EVOL, even if it kills him. As he is about to finish Jin off, Kouga/Alphasz appears to save Jin, fueled by the power Ichirou's clone gave him. During their sword fight, however, Kouga/Alphasz pulls out his gun and executes the Knight Player, stating his pride and recklessness led to his downfall.
Similar to players but a higher ranked class (G3), they are based in the arena the Players used to fight to the death in. They follow rules and avoid needless killing, and do not meltdown so easily like other players. They would also be known as non-defective players. Most EVOL take pride in their rank and are offended if they are ever called or mistaken as players. EVOL is also the name of a club in the storyline, built specifically for players who disguise themselves as humans within society. EVOL could also mean the player organization. Their control is able to reach as far as the Prime Minister of Japan. It is eventually revealed by Shibaki that EVOL intends to conquer the world and eventually wipe out humanity.
EVOL Leader 
The mysterious leader of EVOL, he intends to conquer the world and wipe out humanity. It is unknown what the extent of his power is, though he has the power to keep players from reverting, and his player form was modeled after a wolf (while he was fully organic). He was one of the original 13 Players that rebelled, and the creator of the G2 and G3 Players. He believes that now they are able to create ZET clones, there is no reason to keep Jin alive. After Seiji's declaration of war, the leader reveals himself to be the owner of the EVOL club. When Seiji threatens to destroy EVOL, Seed beheads and attaches the leader's head to itself, and they proceed to presumably kill Seiji, though he is aware that Seiji survived and orders the Sweeper to keep an eye on him. He soon learns of Seiji launching an attack on Amagi Corp., and orders the Sweeper to kill Seiji.
(Shido). An automatonic, sentient suit of black armor. Not much is known about it, except that it is able to move blindingly fast and can emit deadly laser beams. It also seems to have a "son." After Seiji threatens to destroy EVOL, Seed beheads the leader, then proceeds to attach his head to itself, then seemingly kills Seiji. From then on, he alternates control between itself and the leader.
Seiji Haitani 
(Haitani Seiji). The brains of EVOL, Seiji is considered the first major antagonist of the series. He seems to have an interest in Jin, as he implanted a ceramic spike into Jin's heart in order to allow him to freely become ZET. He is shown to be merciless when it comes to getting what he wants, going as far as to fake the decapitating of Akemi's son in an attempt to get Jin to give him Kanzaki's pendant. While Jin and Kouga are on their respective dates, Seiji delivers a declaration of war to the human race. Afterwards, as he threatens to destroy EVOL if Jin is killed, Seed beheads and attaches the leader's head to itself, and they proceed to presumably kill Seiji. He survives, and soon meets up with Suzuki, the person Youko is staying with. He then delivers a message to Jin, telling him to join forces with him to defeat EVOL, also revealing to him that the Amagi Corp. was funding EVOL and that the black suits were in on it, though that part was a lie. He then launches an attack on Amagi Corp. along with Hayami, the Knight Player, and Suzuki ("Katou"). During the attack, it is revealed that he is holding Hanako hostage, as a means of making Jin do what he wants. After the death of the Knight Player,he starts activating explosives across Amagi Tower, and he confronts Kouga/Alphasz with the opportunity to help Jin achieve his "True ZET" form, in order to see if he can remain his true self or become an ally of EVOL.
The Sweeper 
(Suipā). Little is known about him except for his appearances to kill off defective players, and that there are dozens of him. He also shows some interest in ZET and wishes to fight with him (chapter 70). Jin/ZET is now known as "the Black Sweeper "(Chapter 88). It is later revealed that the Sweeper serves EVOL.
Souya Inzen 
(Inzen Sōya). Another high ranking EVOL, he and Seiji are two of the three main EVOLs, along with their mysterious leader. He is shown to disapprove of the tactics Seiji uses to get what he wants, and is weary of him doing whatever he wants. He is also strong enough to defeat Kouga/Alphasz in an instant. When he first appeared, he and Kosuri/Bat Player kidnapped the creator of the "Ginga Choujin Alphasz" anime series for unknown reasons.
The manga was first a one-shot from a set of four published between 1989 and 1994 in Shueisha's Weekly Shōnen Jump magazine. Other one-shots compiled were "Shin-no-Shin", "Woman in the Man" and "Shadow Lady". Zetman started serialization as a full-fledged series in the seinen magazine Weekly Young Jump from 2002 and is still ongoing. As of October 2011, the serial chapters were collected into 16 tankōbon, the first one released on November 19, 2003, and the 16th one on October 19, 2011.

The Animeland reviewer noted that the author's previous tales were about "teens' trifles", in contrast to Zetman's "brutal adventures with a profound darkness", and that they preferred Zetman to the author's other works. Animeland noted that Zetman was serialised over a period of many years, which Animeland says gave "the advantage of time to refine the script". Mickaël Géreaume felt that the first volume was inspired by the author's great love of Batman, finding it surprising considering the author's other works were romantic comedies.
