Characters: Gantz

    open/close all folders 



"Your lives have ended. How you use your new lives is entirely up to me. That's the theory, anyway"

  • Adaptational Villainy: It's the real bad guy in the anime, where the manga's eventual plot is absent, making the hunt simply something Gantz does for its own sick amusement.
  • Arson, Murder, and Jaywalking: Harbinger of death, damnation, and dirty nicknames.
  • Big Bad: So it first. Played straight in the anime.
  • Blue and Orange Morality: Assuming it has any morals, they're completely alien to anything resembling human morals.
  • Cloning Blues: Since it basically copies people the moment before they are killed (or at least, not fatally injured), Hunters who think on it end up with this.
  • Cosmic Plaything: This is essentially what it has in store for the people it collects.
  • Dissonant Serenity: "8 Points! Total 46 Points! 54 to Go!" After Kurono returns as the Sole Survivor of the nightmarishly intense third mission.
  • Humanoid Abomination: It is a hairless comatose man wired inside of an indestructible black ball that carries weapons, power suits, teleportation capabilities, and poor instructions on finding and killing deadly alien invaders.
  • Hunting the Most Dangerous Game: Clueless humans with high tech weaponry hunting sneaky alien invaders.
  • In Love with Your Carnage: Toward the particularly Badass or Blood Knight characters.
  • Jerkass: Deliberately spites, insults, and degrades the players, even when they are at their lowest.
  • Killed Off for Real: You know shit has gotten real when the Giant Aliens attack the Gantz room, blowing the black ball out of the building and into the street, crushing the head of the man inside. Though, there's more where that one came from.
  • Lack of Empathy: Life, death, sacrifice, loss, even The End of the World as We Know It. It's all a fun game to Gantz.
  • Manipulative Bastard: Seems to be part of its programming.
  • Meaningful Name: Averted, no one really knows what "gantz" means. It's possibly just a slang term used to address the black ball that got around amongst the Hunters.
    • Given the spheres' origins, it's likely a misspelling of the German adjective/adverb ganz ("complete" or "completely"). Still meaningless in context, though.
  • Me's a Crowd: At first one Gantz seems bad. Then you find out there are thousands, if not, millions of Gantz balls on assembly lines and an endless supply of carbon copied men to "pilot" them.
  • More Dakka: Gantz supplies its participants with the best in alien engineered weaponry, all of which can be incredibly destructive if used correctly.
  • The Nicknamer: Gantz gives all the players nicknames based on appearance or behavior.
  • Nightmare Fetishist: It picks the sickest, nastiest, most lethal aliens and monsters for the Gantz teams to kill.
  • An Offer You Can't Refuse: Gantz implants bombs in the heads of those whom it recruits; if you turn it down, your head goes boom.
  • Psychopathic Manchild: The fact that Gantz has the sense of humor of a twelve year old Call of Duty troll makes the fact that it sends random humans on horrifying suicide missions even scarier.
  • Troll: Like no other. Disrespects and inconveniences the players at every turn, delays the firing mechanism on all of the guns, alters the rules of the game on a whim, and targets aliens that are either a) worth next to no points, or b) the least dangerous out of several that are extremely dangerous. Worst of all, it doesn't do it because of programming or anything, it just likes fucking with the poor souls it traps.
  • Unwitting Pawn: As much a slave to forces beyond its control as the players it plagues. Although its powers are still near godlike and can be used to deadly effect no matter whose hand is controlling it.
  • We Have Reserves: Not just the endless supply of potential Hunters, but there are literally thousands of Gantz balls in production, waiting to make life hell for humans and aliens by the score.
  • Well-Intentioned Extremist: While it can't be denied that many of the creatures Gantz targets need to be stopped, the methods it uses to achieve these goals are cruel and unusual.
  • You Have Outlived Your Usefulness: Gantz doesn't really play favorites. Everyone is expendable.
  • Your Days Are Numbered: As part of its recruiting speech, it explicitly tells its new hunters that their lives are its to decide.

     Tokyo Team 

Kei Kurono

"At least my world views don't come from comic books and video games! You're living in a fantasy!"

  • Becoming the Mask: The whole reason he originally went out with Tae was because of a penalty game.
  • Bishōnen: Especially in comparison to the generally very ugly rest of the cast, Kurono is small and slim with a boyish face.
  • Butt Monkey: Outside of missions.
  • Character Development: Goes from a man who's only really concerned about himself and sex. To a Badass, risking life and limb for someone he loves.
  • Designated Hero: Starts off as one, a selfish and mean-spirited teenager obsessed with sex and not much else. His experiences with Gantz (as well as postive influence from Kato) set him on the path to becoming a more mature, heroic person.
  • The Determinator: He's horribly outclassed, but his will to survive is strong enough that it doesn't matter.
  • Hopeless Suitor: To Kishimoto, who is firmly attracted to Kato and ignores his advances.
  • Jerk with a Heart of Gold: Grows into a legitimately kind person whose still rough around the edges by the later parts of the story.
  • Jerkass: He begins the story as a very self-centered young man, seen when a homeless man falls on subway tracks at the beginning of the story and he hopes that the more heroic Kato won't call him over to help.
  • The Lancer —> The Hero: Begins the series completely dependent on Kato's leadership, but grows into a capable leader himself over time.
  • Lovable Sex Maniac: Though, the 'loveable' is disputed among fans.
  • Love Hurts: His crush on Kishimoto ends badly for all involved on multiple levels.
  • Magnetic Hero: Inspires loyalty, courage, and determination in his teammates. These traits and how he embodies them often lead to women wanting him and men wanting to be him.
  • Male Frontal Nudity: There's a very graphic closeup of his erect penis in chapter 168.
  • Mr. Fanservice: Probably the only male Seinen protagonist seen nude this frequently.
  • Official Couple: With Tae.
  • Our Hero Is Dead: Kurono gets killed in a fight with vampires, although it doesn't take that much (in story) time to get him revived.
  • Ordinary High-School Student
  • The Protagonist: Gantz is focused on his (un-)life as he gets sucked into the world of alien hunting.
  • Playing Against Type: Chris Ayres normally plays deep-voiced characters, so it's surprising he'd play a young teenager. Plus, where else have you seen Chris play a lead character?
  • The Unfavorite: His parents could give a rat's ass about him, preferring his outgoing younger brother Akira. His teachers don't respect him. And the only friends he has at school are disloyal and superficial.
  • World's Strongest Man: Can sometimes give off this impression. Since he is essentially the one who defeated The Giants and championed humanity, he may truly be this at the end.

Masaru Kato

  • Beware the Nice Ones: Despite his large stature and troubled background, Kato is probably the most sensitive and caring male character in this series. In spite of his large stature and troubled background, he is a force to be reckoned with when forced to defend himself or others.
  • Big Brother Instinct: He is very protective of his little brother.
  • Cartwright Curse: When he finally acknowledges Kishimoto's feelings for him, she dies protecting him. Then happens the same with Anzu after she planned to move and merge their families. Fortunately for her, she gets revived.
  • Chronic Hero Syndrome: What gets him killed in the first episode, when he tried to save a bum at the subway. This also appoints him as the first leader of the team, because he is the only one willing to save others.
  • Good Is Not Dumb: He is about as morally upstanding as they come, but he'll still pre-emptively ambush a guy on the toilet in order to defend himself and head off further violence.
  • Guile Hero: While he at first comes off as a delinquent turned Wide-Eyed Idealist, Kato is shown to be a particularly good liar when he has to be and is even skilled at manipulating fights to his advantage.
  • Hero-Worshipper: He had a big admiration for Kurono back when they were kids, which lasted after many years of being apart, to Kurono's surprise.
  • Hunk: Kato is one of the bigger guys in the series, but is still quite easy on the eyes.
  • Reluctant Warrior: Several of the Gantz team members (most of whom didn't exactly volunteer) aren't real gung-ho about the idea of hunting and killing aliens, but Kato is probably the purest example. Most notable in the initial hunt, where he tries to stop the others from killing the first Onion Alien and then tries to talk to the second one (after watching it slaughter several people). Later on he gets more accustomed to his teammates' use of lethal force to the point where it doesn't make him suffer a Heroic Blue Screen of Death and break down crying every time, though he still personally tends to almost always at least try to use the capture/Teleport Gun whenever possible as opposed to one of the "ludicrous gibs" type, and risking himself to save others is one of his defining character traits.
  • Token Good Team Mate: Compared to many of the players (and even back then Kurono was as selfish as the others), he was the only decent and selfless person there.
  • Promotion to Parent: Just as he got fed up with his aunt's mean treatment of him and Ayumu, Kato decides to move out after saving up enough for an apartment.
  • The Strategist: Often embodies this.

Kei Kishimoto

  • Stupid Sacrifice: An alien throws a highly corrosive acid at Katou. Instead of, say, pushing him out of the way, Kishimoto runs around him, blocks him with her body, and takes the blast.
  • UST: With Kurono and Kato.
  • What Happened to the Mouse?: The Kishimoto who Kurono and Kato loved and lost was a clone. The real Kishimoto survived her suicide attempt and later, the alien invasion, living to the end of the series.

Joichiro Nishi

"Remember how I said you had a little bit of potential last time? I was wrong. You should be the first one to die!"

  • Jerk with a Heart of Jerk: Just after saving Takeshi from the Alien Invasion and leading the readers to think he had any redemption arc ahead, he confronts Kurono and tries to murder Tae in front of him.
  • Jerk Ass Has A Point particularly in episode 9 during his trolling rant.
    • Also, near the end of the manga, Nishi acts like everyone is insane when they decide to use the teleportation ability of the Gantz spheres to rescue captured humans on the enemy mothership rather than immediately striking its weak point to destroy it. He's right, and humanity almost loses because of the delay.
  • Killed Off for Real: He bites the dust in Chapter 366. It's interesting to note that Nishi, of all people, cries out for his mother as the alien ship disintegrates.
  • Lack of Empathy: Doesn't hesitate to kill anyone or feel sorry for the frequent massacres at the missions.
  • Not So Different: He does that with Kei in the fourth episode.
  • Sadist: He tortured small animals when she was a child! What the hell!?!?
  • Serial Killer: Before Gatnz, many of the other students noted that he killed animals. Becomes fully this when the entire classroom (sans the only girl who had a crush on him) tossed him out of the window and left him for dead without feeling sorry. In response, Nishi returned and slaughtered them.
  • Slasher Smile: Boy howdy, does he ever sport one in chapters 364 and 365.
  • The Sociopath: Kills animals for fun, constantly plays mind games and regularly lets random people (who he sees as bait) get slaughtered by aliens he knows how to fight.
  • Token Evil Team Mate: Aside from Izumi and the ocassional rapists or jerkasses recruited by Gantz, he is the most notably evil.
  • Troubling Unchildlike Behavior: He's only in eighth grade!
  • Tsundere: In the Gantz PS2 game if you follow his route. He even says something along the lines of "Don't get the wrong idea; I didn't come here to help you" during one event. This is mind-meltingly weird for anyone who's familiar with the Jerkass Nishi from the manga and anime, to say the least.
  • Villainous Breakdown: Basically every time he finds himself at a disadvantage, he starts losing his shit and whining for the people he ruthlessly antagonized earlier to help or spare him.
  • Younger Than They Look: He looks like he's 18 at the youngest. He's in middle school. Most likely done to save the audience the horror of seeing someone barely into puberty committing the atrocities he does.

Sei Sakuraoka

  • Expy: Sei Sakuraoka of Lara Croft
  • Horrible Judge of Character: Sei finds Kurono way more impressive than he actually was at the time they met, leading her to die defending his life against the 1000 Arms alien.
  • Romantic False Lead: She has sex with Kurono right after meeting him and already thought of herself as his girlfriend, while Kurono was still trying to move on from his failed attempts to woo Kishimoto. She dies on that very same mission and Kurono doesn't revive her.

Shion Izumi

  • Alas, Poor Villain: The first time he dies, his last thoughts are of his intense fear of death. The second, he looks back on his actions with shock and regret.
    Izumi: (Seeing the army of vampires he just massacred as he dies) Did I really do all this?
    • YMMV on that one; it's possible to read it not so much as shock and regret as "damn, even I didn't know I was that awesome."
  • Anti-Hero: Type V-> Type IV.
  • Ax-Crazy: Enjoys the thrills of the missions so much that he considers his decision of leaving a mistake... So he decides to kill a lot of people at Shinjuku dressed as a Black Man.
  • Morality Pet: Hoi Hoi is his literal morality pet. Also his girlfriend, who he was at first indifferent toward but ended up dying for. He even tells her he's going to take her to Disneyland in his last moments.
  • Nominal Hero: He initially appears as a model student that everyone admires and Kurono envies, later to be revealed that he is a sociopath and Serial Killer.
  • Omnicidal Maniac: He goes on a shooting rampage just so he can get killed and return to the game. This also bulks up the team's roster.
  • One-Man Army: As The Vampires quickly discovered.
  • Pet the Dog: Cold-blooded killer Izumi will not hesitate to murder dozens of innocent Tokyo citizens, including Kurono's girlfriend, but he will save Hoi Hoi when escaping a bunch of dinosaurs.

Tae Kojima

  • Rescue Romance: She initially agreed to date Kurono and was implied to be aware of the bet. Then they grow closer after Kurono went out of his way to save her from the alien that massacred the entire classroom.
  • Second Love: While it started as a bet and a Rescue Romance, Kurono grew to love her genuinely.

Yoshikazu Suzuki

  • Back for the Dead: Brought back by advance aliens only to kill him again to prove a point.
  • Cool Old Guy: Instantly becomes Kurono's friend and also offers his house to both Kaze and Takeshi once he discovers the two are homeless.
  • Cruel and Unusual Death: Each death, but particularly when he is beaten and torn apart by the Renaissance Statue Aliens.
  • Dying Moment of Awesome: In that case he went guns blazing, trying to defend Inaba.
  • The Lancer: To Kurono, since he and Reika are the first ones Kurono directly helps to survive.
  • Nice Guy: He gives advice to Kurono, has good interactions with the rest of the team and offers his house to Kaze and Takeshi.
  • Nominal Importance: Subverted. When he's first introduced, we don't learn his name for ages, and as an unassuming middle-aged guy with an aversion to violence and no immediately distinguishing character traits beyond general geniality, he seems like he's certain to die without lasting one fight... but he becomes one of the main cast and survives longer than almost anyone.
  • Only Known by Their Nickname: The others only call him "The Old Man"

Daizemon Kaze

  • Badass Longcoat: Sports a sleeveless one in his civilian life.
  • Badass Normal: Doesn't wear a suit during his first mission. He ends up beating to death a few alien velociraptors and briefly defeats Gantz's superhuman target in a fistfight.
  • Bruiser With A Soft Centre: After stablishing himself as the tough guy from the group, he starts to open up to Takeshi's worshipping him as Muscle Rider, and cries when he tells his backstory.
  • Doesn't Like Guns: Fights every alien hand to hand, regardless of how powerful they are or if they even have hands.
  • The Drifter: He travels around a lot, basically looking for someone who can beat him. Stays put when he finds that person in Kurono.
  • Evil Laugh: When facing a particularly challenging foe, he howls with laughter, sinisterly implying that he fears nothing. This might be a defense mechanism, actual joy or both.
  • Gentle Giant: Towards Takeshi.
  • In-Series Nickname: "Muscle Rider"
  • Knight of Cerebus: It is quite a devastating display when he decides to really cut loose on an enemy. The rest of his team would agree.
  • Made of Iron: The first time he dies, Kaze is riddled with bullets at point blank range by Izumi while he himself is crushing Izumi's throat. He doesn't go down until the gunfire cuts his legs apart, leaving him crippled and vulnerable.
  • A Man Is Not a Virgin: Subverted. He's one of the most competent fighters in the series...he's still a virgin though.
  • Manly Tears: After finding out Takeshi's 'stepfather' beat him to death over a pudding cup, while his mother did nothing to stop it.
  • No-Holds-Barred Beatdown: A master of these.
  • Papa Wolf: Kaze to Takeshi. When one of the Nura alien's attacks hurt Takeshi, Kaze went apeshit and attacked it, dealing more damage than Oka Hachirou did even with his Power Armor.
  • Promotion to Parent: for Takeshi.
  • Sarashi: He likes to wear this, along with old fashioned geta.

Hiroto Sakurai

  • An Arm and a Leg: Turns out to be fatal
  • The Atoner: Sakurai has a guilty conscience from murdering his classmates who abused him and tries to make up for it by saving lives during Izumi's massacre.
  • Back from the Dead: Sakata uses his points to revive him.
  • Heroic Sacrifice: As the building collapses, he uses his remaining strength to divert the rubble from falling onto two alien children mourning their dead mother.
  • Killed Off for Real: The explosion removes all of his limbs. As if that wasn't enough, the building's roof collapses on him.
  • Morality Chain: His was his girlfriend Tonkotsu, who made him use his powers to save people. When she gets killed during the invasion, Sakurai goes on an alien-killing rampage.
  • My God, What Have I Done?: Sakurai experiences this after realizing that his massacre of giant aliens involved taking the life of an infant and an elderly giant woman in Chapter 340.

Kenzo Sakata

  • Cool Shades: Always wearing them.
  • The Fatalist: After a few missions, Sakata, tired of the life and death situations Gantz puts he and others through, tells his teammates not to resurrect him if he dies. These are even his last thoughts, which he conveys to Sakurai telepathically.
  • Heroic Sacrifice: [spoiler:Dies in order to buy his team time to escape.]]
  • Killed Off for Real: Overloads his psychic abilities trying to stall the Nuraryhon Alien.
  • Nerves of Steel: When he confronts the fire demon during their duel, after Sakurai has been killed.
  • Punch Clock Hero: He has a very nonchalant, indifferent attitude towards others, despite his heroic actions.

Reika Shimohira

  • I Want My Beloved to Be Happy: Reika uses her 100 points to resurrect Kurono's girlfriend...and then later subverts the trope by resurrecting another Kurono for herself.
  • Killed Off for Real: She saves Kei-2 at the cost of her own life between chapters 356 and 357.
  • The Lancer: In the Osaka arc.
  • Love Makes You Crazy: It seems like Reika is starting to head down this road after being rejected by Kurono. She resurrected a second copy of him after getting 100 points in Italy.
    • She feels guilty about it imediately afterwards though and when the Alien Invasion begins she seems more eager than usual to sacrifice her life in the defence of other as some sort of atonement
  • Rescue Romance: She falls in love with Kurono after he advised her to use the suit to survive and seeing him in action to save the group.

Takeshi Koumoto

  • Apologetic Attacker: He does this to the first alien he kills, despite the fact that it was trying to eat him just moments earlier.
  • Children Are Innocent: Even with his abusive childhood and all the violence around him, he is still a good kid.
  • Hero-Worshipper: To Kaze, who he literally thinks of as a superhero, since before his death he used to draw an imaginary hero named "Muscle Rider", who looked just like him.
  • Morality Pet: To Kaze and the rest of the team... even Nishi.
  • Pint-Sized Powerhouse: In the Gantz suit.
  • What Happened to the Mouse?: The last we see of Takeshi is when Nishi teleports away and leaves him in some random room during the alien invasion. It's assumed he will be reunited with Kaze, though.

Kouki Inaba

  • Made of Iron: He is tortured and made a multiple amputee by the Renaissance Statues, and is still able to take down dozens of them before getting killed by their Knight of Cerebus.
  • Mauve Shirt: Interestingly, he was perfectly fine as long as he kept a Red Shirt status, and got killed off right after receiving his Character Development.
  • Redemption Equals Death: Though more of an Usefulness Equals Death or Action Equals Death, as he'd stopped being a Jerkass a bit earlier.
  • The Resenter: He really can't stand Kurono for all the attention he gets for his actions, especially from his crush, Reika.

Hoi Hoi

Second Kei Kurono

     Osaka Team 

The Nerd

  • A Day in the Limelight: A whole chapter is dedicated to him, which covers everything he went throught after his first battle, how he became the only remaining team member (the others chose to leave) and we also discover that he was also at the Italy mission, which granted him the points to revive Anzu.
  • Did You Just Punch Out Cthulhu?: Using the Nurarihyon Alien's severed head to disintegrate several of monsters in its own brood.
  • Fish out of Water: The Osaka Arc is his first time as a Gantz player. The only reason he survives is because he and his friend were smart enough to wear the suits, and because more than a few people take the time to save him.
  • Hero-Worshipper: Towards Masaru Kato.
  • Killed Off for Real: Decapitated by The God of War Giant.
  • The Load: More often than not, until he got used to the missions.
  • No Name Given: The others never refer to him by name.
  • Took a Level in Badass: When he managed to survive the Italian mission with only a frightened little girl as a teammate and still earn enough points to resurrect Anzu.
  • Undying Loyalty: Went out of his way to gather enough points to revive Anzu, so she can be reunited with Kato again.

Anzu Yamasaki

  • Hero-Worshipper: Like The Nerd, Anzu is so astounded by Kato's bravery that she not only joins his cause, but falls in love with him on the same night that they meet.
  • Irony: Of all the Osaka members, Anzu lives possibly the most morally ambiguous normal life. While most of the Psycho for Hire types you read about earlier are shown to be mild mannered members of the workforce in their normal lives, the sweet and attractive little Camper Anzu is shown to be passively neglectful toward her son so she can focus on earning money. By illustrating porn. In her living room.
  • Morality Pet: Love for her son compels her to survive. Love for Kato compels her to be heroic.
  • The Oathbreaker: Dies to prevent Kato's death, even though she made him swear earlier not to die so that they and their families could all live together. They each tragically lampshade this as she is being killed.

Hachirou Oka

  • Blood Knight: A subtle version.
  • Combat Pragmatist: Uses the most powerful weapons and armor Gantz has to offer not to protect the weak innocent, but to increase his odds in battle despite the fact that he is plenty dangerous without all of it.
  • Cruel and Unusual Death: Apparently ripped apart by Nurarihyon. We only see that he's missing everything below his chest.
  • Curb-Stomp Battle: He's cleared seven missions with 100 points. At the time, it was considered next to impossible to get more than a few points each mission.
  • The Ghost: Remains invisible for most of the game, letting the rest of his team eliminate the lesser aliens and draw out the greater ones so that he can collect on the points.
  • Foreshadowing: All of the technology he collected as achievement awards for the missions he completed are later revealed to be Gantz's war arsenal against the Giant Aliens.
  • Humongous Mecha: Pilots one when he first appears.
  • Know When to Fold 'Em: It turns out that the secret to surviving a long time in Gantz is to back off when an alien is obviously too powerful for you, and just run out the clock or hope someone else kills it. Who knew? (It doesn't save him this time, because the alien is a Blood Knight who wants to keep fighting him, but it's almost certainly how he survived so long in the first place.)
  • Lack of Empathy: Does not feel the least bit bad about leaving the scared and uncertain Tokyo Team to deal with the monster even he can't kill.
  • Large Ham: Has his moments.
    • "Despite this look, in grade school I PLAYED PING PONG!"
  • Lightning Bruiser: Outside of the armor.
  • Powered Armor: Oka is the first player seen wearing the Gantz version, as well as piloting its towering mechanized war machine.
  • Straight Edge Evil: In the Osaka spinoffs, Oka appears to be a well-adjusted office worker by day, quiet and efficient. Though, he is clearly bored, and even more clearly exhilarated when he receives the signal for his next and last mission.
  • The Worf Effect: It appears that Oka (who has already taken down a Godzilla level monster) can be the only one capable of defeating the Nurarihyon Alien that has so far eliminated three of his best teammates, dominated half of the Tokyo Team, and proven itself unkillable. Even with all his wonderful toys, this turns out to not be the case. Since both got a lot of buildup, this avertings it for the monster, but plays it straight for Oka himself.
  • Worthy Opponent: Nurarihyon considers him to be something like this, claiming "he was fun" when confronted with Kaze's "predictable" martial arts. It even abandons its fight with the Tokyo Team to hunt Oka throughout Osaka, and destroys several buildings in the process of killing him.

Kyou Hanaki

Kazuo Kuwabara

  • Laser-Guided Karma: After using his considerable abilities to violate extraterrestrial species, he loses his arms, legs, and, possibly, his genitals in his fight with The Nurarihyon Alien.
  • Lovable Sex Maniac: To the Osaka Team. The Tokyo Team would disagree about the "lovable" part. And the aliens would strongly disagree.
  • Lack of Empathy: His reaction to The Nerd now left alone in the Osaka Team: "Oh, right. Guess you're kinda fucked next time, huh?"
  • Large Ham: Very, very expressive during his rapes.
  • Nightmare Fetishist: Legitimately finds the aliens he rapes to be hot, especially Nurarihyon's blob of beautiful women.

Nobou "Knob" Muroya

  • The Leader: Describes himself as such, though, Oka is the most dangerous and experienced member of the team.


  • Cruel and Unusual Death: He gets caught and consumed by Nurarihyon's form (a giant and bizarre mass of naked women). Though, it does spit out his head.
  • Heterosexual Life-Partners: With Knob. They are even revealed to work together as polite fast-food workers by day.
  • Pride: Seems to think he's invincible.

Three Sadists

  • Dirty Coward: Just as the last one is given the chance to run away and live, he tries to stab the infinitely more powerful alien in the back. And fails miserably.
  • Laser-Guided Karma: Given their title, the manner of their deaths, i.e. being chopped apart, was very fitting.
  • Master Swordsman: Proven otherwise when they encounter a couple of aliens who actually are.

Sumiko Yamada

  • Crouching Moron, Hidden Badass: Despite the fact that we see her do nothing but stand around and run away, she is still able to earn enough points to buy her freedom after she survives.
  • Dirty Coward: Like Miho, Sumiko is perfectly fine with letting the tough guys do the work while she watches, and abandoning the fight when it looks like they will lose.
  • Gag Boobs: Which her team's Gantz very much appreciates.
  • Heterosexual Life-Partners: With Miho.

Miho Yamanaka

  • Crouching Moron, Hidden Badass: Miho is also seen doing nothing but standing, screaming, and running, and still has enough points to buy her freedom after she survives.
  • Dirty Coward: Like Sumiko, Miho is perfectly fine with letting the tough guys do the work while she watches, and abandoning the fight when it looks like they will lose.

     Katastrophe Team 

Takeda Hyouma

  • BFG: Carries two.
  • Dogged Nice Guy: Towards Reika.
  • Fanboy: He is ecstatic to find out Reika is also on the team and says he was a devoted fan of her during her Idol career.
  • Heroic BSOD: Suffers one briefly after he finds out Reika died.

Maeshima Ryuuji

  • A Man Is Not a Virgin: Averted. He passionlessly admits to manly Yazawa that he is a virgin. Doesn't matter since he's ten times as manly.
  • Killed Off for Real: Seems to have happened to him when he fights The God of War Giant to defend Kurono.
  • Loners Are Freaks: He rarely talks to anyone, shows next to emotion, and is, overall, a very scary-looking person even though he is one of the heroes.
  • OOC Is Serious Business: As he dies, Ryuuji is happy and smiling for the first time.

Mary Mcclane

Sekine Mokoto

  • Cruel and Unusual Death: Suffers one of the cruelest and most unusual deaths when he is hit by one of the Pandora's Box spores, turning him into a violent mutating mass of his own extremities, clothing, and weapons.

Yoshikawa Kaiji

  • Badass: Probably the most badass out of the Katastrophe team members.
  • Dying Moment of Awesome: Killed immediately after delivering some serious blows to the nigh invincible God of War Giant, including cutting off some of his fingers, and letting everyone know that they can beat him.
  • The Strategist: From time to time.
  • Wham Line: "Gantz can't bring people back to life anymore. It can't heal injuries either. Nothing like that."

Yazawa Toshio

  • Badass Bystander: Is rendered to this position when he is tasked with carrying around The Nerd when the latter's foot gets crushed.


Green Onion Aliens

  • Innocent Aliens: Appear to be living peacefully apart from humanity.
  • Inscrutable Aliens: It's hard for Kato to explain himself to the enraged alien with a heavy language barrier between them.
  • Knight of Cerebus: The Onion Alien's father.
  • Lightning Bruiser: Onion Alien's father.
  • Little Green Men: At first the Onion Alien appears to be a scared, odd-looking little green-skinned boy. Then his dad shows up. He is green, but he is by no means little.
  • Nigh-Invulnerability: The Onion Alien's father is shot several times, hit by a car, beaten to a pulp, and ensnared in unbreakable wires, and is still standing when he is transferred away.
  • Shoot the Dog: The son is hunted down and shot to pieces by a group of ignorant and/or violent new Gantzers. Just when it looks like the father has turned the tables on all of them, he is taken down by Nishi.
  • Starter Villain: Despite the terror Kurono, Kato, and Kishimoto endured during this mission, the Onion Aliens are nothing compared to what they face later.

Tanaka Aliens

  • Human Outside, Alien Inside: Fails at the "human outside" part so bad that they must remain invisible even in disguise.
  • Innocent Aliens: Allegedly. They pay for food they take from the store while invisible and they don't attack anyone until they are provoked. However, accidentally stepping on one of their baby chick siblings is usually enough to provoke them. And if so, there are likely many innocent bystanders who stepped on them while they were invisible and got killed as a result.
  • The Worf Effect: This mission proved that Anyone Can Die when Nishi, the know-it-all veteran hunter, was beaten and violently killed by the first Tanaka alien the team came across.

Buddhist Temple Aliens

  • Absurdly Sharp Blade: The swords which 1000 Arms possesses are capable of cutting through flesh, bone, the Gantz suits, and even stone.
  • Bling of War: All of their statue disguises can count as this, especially 1000 Arms.
  • Blood Knight: Innocent or not, these aliens are talented, destructive fighters. When it can speak english, 1000 Arms is almost psychotic in its enthusiasm about beating Kato to a pulp.
  • Break the Haughty: What this mission symbolizes for Kurono. His over-inflated ego is quickly demolished when the girl he loves is melted in front of him, he loses An Arm and a Leg, and finally he finds out that he is the mission's Sole Survivor.
  • Defiant to the End: 100 Arms kills Kato during its last moments... after it has already been decapitated
  • Disc One Final Boss: 1000 Arms is this for Kato.
  • Dual Wielding: The 1000 Arms statue carries two swords.
  • Foreshadowing: Kurono kills the largest statue by skyrocketing his whole body straight into its head... which is also how he ends up killing his final enemy in the series, also a giant.
  • Frickin' Laser Beams: 1000 Arms has an ornament which can project deadly ones.
  • Healing Factor: 1000 Arms has one, via an ornament it possesses which seems to reverse any damage done to it so long as the ornament remains in tact.
  • Hero Killer: 1000 Arms kilsl Kato.
  • Hoist by His Own Petard: When Sei kicks the acid vial out of 1000 Arms' hand, melting half of its statue disguise and its Time Master ornament.
  • Hollywood Acid: 1000 Arms makes use of acid to fight, which viciously melts Kurono's arm and leg when he gets too close while attacking it.
  • Human Outside, Alien Inside: Buddhist statue outside, lizard alien inside.
  • I'm a Humanitarian: A couple of these aliens eat the brains of their victims.
  • Innocent Aliens: 1000 Arms claims they never did anything to hurt humans and have no idea why they are being attacked. Since they are specifically in disguise as peaceful statues, it probably was not lying.
  • Knight of Cerebus: Played with. The Rowdy and Grumpy Aliens seem like this compared to the aliens in the first two hunts. Then the towering (and by far the largest) Buddhist statue breaks out of the temple... and is unceremoniously killed by Kurono. Once these titans have been taken down, it looks like easy street for the team. Then they find The 1000 Arms Alien.
  • Multi-Armed and Dangerous: 1000 Arms' statue disguise, and possibly all of them in their true form.
  • One-Winged Angel: 1000 Arms
  • Pyrrhic Victory: Kato fights to the bitter end, finally slaying 1000 Arms and rejoicing that he will get to go home to his brother. Then he's killed by the alien's final attack, seconds before he would have been sent back.
  • The Reptilians: Out of the statue.
  • Roaring Rampage of Revenge: 1000 Arms does not respond well to the puny humans who eradicated its companions.
  • Shockwave Clap: The larger statues can do this.
  • Shoot the Dog: The entire mission is one long Shoot the Dog. Becomes a literal example, when one of the statues smashes the Team Pet dog's head without any warning.
  • Starter Villain: The most traumatizing starter villains yet.
  • Symbiotic Possession: 1000 Arms consumes a nerdy Gantzer's brains and adopts his personality to communicate with humans. The guy realizes this, but then he begins to like how powerful he feels in the alien's body.
  • The Worf Effect: Just when it looks as if Kurono has accepted his role as the series definitive badass, 1000 Arms crushes him and slowly slaughters the rest of the team.

Shorty Aliens

  • Badass Boast: "First, I will defeat you. Then, I will kill you. I will never forgive you for what you have done."
  • Break the Haughty: They finish what The Buddhist Temple Aliens started as far as convincing Kurono that he isn't as cool as he thinks.
  • Charles Atlas Super Power: Gantz describing them as "Strong" doesn't quite cut it.
  • Face Death with Dignity: The last one only stands up straight and glowers at Kurono before it explodes.
  • Human Outside, Alien Inside: The last one somehow perfectly disguises itself as a student at Kurono's school, and continues to wear it even as it massacres his classmates.
  • Hyper Awareness: "I can see in to your heart." It's true in more ways than one.

Kappe Aliens

  • The Big Guy: The Kappe Alien, though it started out as a little guy.
  • Elite Mooks: The Velociraptors and smaller Brachiosaurus.
  • Evil Versus Evil: The T-Rexes and Triceratops' don't get along and end up fighting over who kills Izumi.
  • Extra Eyes: The Horned Brachiosaurus spontaneously grows hundreds of eyes on its underbelly when Kurono tries to sneak attack it from below.
  • Giant Mook: The T-Rexes and Triceratops.
  • Humanoid Aliens: The Kappe Alien.
  • Intelligent Gerbil: Many are disguised as prehistoric dinosaurs, despite the fact that they can shift sizes, stand upright, develop fists, and breathe fireballs.
  • Knight of Cerebus: The Horned Brachiosaurus.
  • Nightmare Fuel Station Attendant: The Kappe Alien looks kind of cute and harmless at first, until you realize it controls the dinosaur aliens, has Super Strength, and can turn into a hideous giant.
  • Outrun the Fireball: Kurono literally has to do this when he's being chased by the T-Rexes, who shoot fireballs out of their mouths.
  • Psychopathic Manchild: The Kappe Alien is very insecure, thinking it's being attacked because it is "looked down upon" by others, and retaliating by using the dinosaurs as weapons.
  • Shrinking Violet / The Berserker: The Kappe Alien is pretty timid normally, but is insatiable when pissed off.
  • Size Shifter: The angrier these aliens get, the bigger they get.
  • This Is Unforgivable!: The Horned Brachiosaurus, who is apparently the mother of the other dinosaurs, reacts this way when it is the only one left.
  • The Worf Effect: Just as The Kappe Alien grows to an enormous size, becoming a One-Winged Angel, it is easily cut in half from behind by Izumi.
  • Would Hit a Girl: It's pretty amusing when the Kappe Alien gets jumped and beaten up by an angry shopaholic girl. Then it starts fighting back and sics its pet velociraptors on her.

Ring Aliens

  • Anti-Climax: Despite their enormous size, powerful weapons, and menacing appearance, they are taken down quite easily.

Oni Aliens

  • Boldly Coming: A truly horrific example when Inaba and Reika start having sex in the middle of the blood soaked mall. The real Reika shows up and the one on top of Inaba begins transforming and attacking the others while he is still inside of it.
  • Dangerously Genre Savvy: They've been working with the vampires to set up an ambush for the Gantz Hunters.
  • Demon Lords And Arch Devils: The leaders seem to be these.
  • Eldritch Abomination: If they aren't aliens or demons, they are this.
  • Expy: Many of their abilities make them appear reminiscent of the alien in John Carpenter's The Thing.
  • Hellfire: One of the leaders uses this to kill several members of the Tokyo Team, including Sakurai.
  • Horny Devils: Rape is as commonplace as murder for these guys.

Nurarihyon Aliens

  • Attack Its Weak Point: The only known way to kill Nurarihyon is to hit him when his back is turned. Easier said then done...
  • Cloud Cuckoolander/Psychopathic Manchild: Nurarihyon observes attacks made against it as if it were observing someone challenging it at chess.
  • Eldritch Abomination: A whole city district full of them, led by one of the biggest ones ever.
  • Evil Counterpart: The samurai alien couple to Host Samurai and Kill Bill. Or rather alien counterparts to the vampires.
  • Eye Beams: Nurarihyon's are devastating. At it's most basic form it disintegrates individuals exposed to his glare for too long. When he's pissed off, the eyes blows up multiple building in just mere seconds.
  • Intelligent Gerbil: More than a few are these.
  • Knight of Cerebus: Despite the number of atrociously difficult aliens seen throughout, Nurarihyon takes things to a whole new level of fear and hopelessness.
  • Male Gaze: Whether Nurarihyon has this himself or merely shapeshifts into mutated buxom women to distract his enemies is debatable.
  • Man of Wealth and Taste: Though they are bizarre monstrosities, Nurarihyon, its two powerful friends, and the samurai alien couple see themselves as this.
  • Our Monsters Are Weird
  • Sherlock Scan: If Nurarihyon sees and understands how an opponent is beating it, it will simply shapeshift into a form that can't be beaten in that way.
  • Smug Super: Nurarihyon, and the rest take after it.
  • Soft-Spoken Sadist: Nurarihyon is prone to making witty little remarks whilst shrugging off his enemies' desperate efforts to defeat him.
    • "I see... mm... yes, I see... I see..."
    • "Observe..." copies Oka's Gantz power armor.
  • Sympathy for the Devil: Though most are violent and predatory, a few are simply defending themselves from or at the mercy of the malicious Osaka Team.
  • Voluntary Shapeshifting: Nurarihyon is perhaps the most disturbing example of this trope.
  • Wretched Hive: Osaka is this thanks to these aliens.

Renaissance Statue Aliens

  • Badass: The Gantz weapons arsenal, which is ordinarily somewhere between sufficient to dangerously efficient, is rendered nearly useless by the speed and power of these aliens.
  • Blood Knight: They all appear to just love destroying humans, especially humans who try to fight like the Gantz teams.
  • Cold-Blooded Torture: Poor Suzuki and Inaba.
  • Curb-Stomp Battle: The biggest one yet.
  • World's Strongest Man: Or aliens. Hundreds, possibly thousands of Gantz teams from all over the world are sent to fight these guys. Those hundreds of thousands end up barely having any time to breathe, let alone fight back.

Giant Aliens

  • The Ace: The God of War appears to be this among the Giant Alien Army...
  • Amazonian Beauty: Most of the female giants, complete with the series standard Gag Boobs.
  • Aliens Are Bastards: See nothing wrong with sacking an entire planet, harvesting the human species for food, and televising the Gantz teams fighting for their lives like football games.
  • Attack of the 50-Foot Whatever
  • Badass: Their army is not composed of lightweights. The God of War is capable of curb-stomping some of the most dangerous Gantz hunters from all over earth.
  • Bishōnen: The God of War is a bishonen giant.
  • Bizarre Alien Biology: Subverted somewhat. They look very much like humans, but are gigantic in comparison, have four eyes, and the males apparently have multiple penises.
  • Boom, Headshot: How Kurono manages to finally kill the God of War.
  • Broken Ace: But is probably this after the Giants have been defeated and his brother has been killed.
  • But for Me, It Was Tuesday: Earth is definitely not the first planet they've invaded and it shows. Though, it may be the last.
  • Call Back: This was a callback to when Kurono killed a giant Buddhist Temple alien in the same manner earlier in the series.
  • Crazy-Prepared: They come totally ready to cripple the secret countermeasures of Gantz, as well as military and governments, and devise several devious ways of putting the Hunters through hell. Not that it helps them win in the end.
  • Elite Mooks: Their exploding, armored lizard minions.
  • The End of the World as We Know It: What they bring about.
  • I'm a Humanitarian: They collect and slaughter humans like cattle and serve them as delicacies.
  • Worthy Opponent: The God of War, and Giants in general, seem to see Kurono as this.

Mothership Aliens

  • Alien Animals: Kurono and Tei happen upon a literal zoo full of them.
  • Bizarre Alien Biology: With extra emphasis on the word "bizarre."
  • Body Horror: Some of these aliens can explode into a cloud of floating light spores. When the light spores touch humans, they enter their bodies and mutate them from the inside out, appendages multiplying like tumors, turning the victims into violent freaks of nature.
  • Knight of Cerebus: The largest of these aliens is some sort of deformed giant with a scowling human face and mysterious abilities. It's so terrifying that the whole team finally decides to run, save Kurono's Clone who wants to prove himself by killing it, and Reika who doesn't want to leave him. After the creature beats Kurono into submission, it fights Reika, and the two kill each other.
  • Mighty Glacier: The largest and most powerful of these aliens hovers over the battle and watches mostly. After it drops to the ground, its movements are very ponderous. However, its telekinetic powers and ability to summon an entire new brood of creepy-crawly aliens makes up for it.

Room of Truth Aliens

  • A Form You Are Comfortable With: Every other panel features them projecting some new random face. It can be Gandhi, one of the aliens that have been defeated, a litter of kittens, etc.
  • Aliens Are Bastards: Fitting that the most powerful ones would also be the biggest bastards.
  • But for Me, It Was Tuesday: Their reaction to pretty much the entire series and everything the characters have been through.
  • Expy: They seem to be a freaky combination of the aliens from Contact, the Engineers from Prometheus, and the monolith from 2001: A Space Odyssey.
  • Good Is Not Nice: Technically, they gave humanity the means to defend itself from dangerous alien invaders. However, the information was given to the mentally challenged daughter of a ruthless German businessman, who used the Gantz technology the way seen throughout the series: enslaving resurrected humans to a sadistic artificial intelligence and pitting them against bizarre, horrifying, highly lethal creatures. The Room of Truth Aliens did not do any of this out of the kindness of their hearts, nor out of any other great concern of theirs. More likely, they just want to maintain some sort of balance in the universe, which was likely being screwed up by the world destroying Giant Aliens.
    • They more or less state that they did what they did in retaliation for the Giant Aliens trying the same crap on them. Basically, "They pissed us off, so Let's You and Him Fight."
  • Greater Scope Villain: They are responsible for humanity's discovery and utilization of the Gantz technology.
  • Karma Houdini: They get away with all the havoc and misery they are responsible for, because there is apparently no one powerful enough to stop them.
  • Kick the Dog: When they resurrect Kishimoto, Sei, Suzuki, and Reika and then immediately destroy them just to prove to Kurono that human life has no value.
  • Lack of Empathy: They tell the disheartened, battle-scarred Gantz Hunters that humans are no different from ants and that everything they do is totally meaningless.


Host Samurai

  • Authority Equals Asskicking: While it isn't clear if he is the leader of the vampires, he is definitely the most badass and has seniority because of it.
  • Embarrassing Nickname: "Host Samurai" is how Gantz refers to him, which "Kill Bill" finds amusing.
  • Evil Is Petty: Acts this way, but not quite. It seems like killing The Hunters started out as business to him, then it became personal, but after he ends up a member of the Tokyo Team and witnesses what they have to go through from their perspective he loses interest in wiping them out.

Kill Bill

  • An Arm and a Leg: Gets her sword arm sliced off during the Osaka mission. She survives and gets it back.
  • Embarrassing Nickname: Either because she is a female wielding a katana or because she vaguely resembles Go-Go Yubari from the movie. Or both.
  • Out-of-Character Moment: Host Samurai is astonished to hear her giggle at his name.
  • Not So Stoic: Has very human thoughts and emotions. For example, when Host Samurai incredulously asks if he just heard her laugh, she appears embarrassed and claims she didn't.
  • Start of Darkness: As a human, her and her friends were led to a club by handsome men in black clothes. These men were vampires who killed her friends and turned her into one of them.

Akira Kurono

  • Aloof Big Brother: Thinks of Kei as this, despite the fact that he is the younger brother and far more aloof.
  • Annoying Younger Sibling: Averted. Akira is conventionally successful in life as opposed to his older brother. Kei finds this fact annoying in its own way at times.
  • Badass Longcoat: Before and after he becomes a vampire.
  • Big Little Brother: Is taller, smarter, more handsome, more confident, and more popular than his older brother Kei. It even leads some to believe he is the older brother.
  • Redemption Equals Death: He warns Kei that the vampires are coming for him, putting his own life in danger. A few panels later Host Samurai is holding his head in the air for Kei to see.
  • Smug Snake: Makes sense when he turns out to be a vampire as well. Even when he warns his brother of his impending death Akira appears only vaguely interested.
  • What You Are in the Dark: Cares more about the safety of his estranged older brother than his cool new vampire friends.
