* AmnesiaMissedASpot: Played straight ''and'' inverted. After the Ikebukuro mission, Kei chose to be freed of the memories, which has the unfortunate side effect of erasing all of his time with Tae... but the physical evidence left ends up triggering his feelings anyway. Then [[spoiler:he's KilledOffForReal by the vampires, and Kato uses his 100 points to revive him... but this Kurono's memories ''end after the Ikebukuro mission,'' meaning that all the time he spent as a free man is lost to him.]]
* AntiHero: ClassicalAntihero
* BadassNormal: Even without the suit, Kurono is a capable fighter.
%%* BackFromTheDead
* BecomingTheMask: The whole reason he originally went out with Tae was because of a penalty game.
* {{Bishonen}}: Especially in comparison to the generally very ugly rest of the cast, Kurono is small and slim with a boyish face.
* ButtMonkey: Outside of missions.
* CharacterDevelopment: Goes from a man who's only really concerned about himself and sex. To a Badass, risking life and limb for someone he loves.
* CharacterRerailment: Possible in-universe example- when Kurono and Kato first arrive at the Gantz room, Kato reminisces about the way that, when they ran together as kids, Kurono was a fearless, unstoppable badass that Kato admired and wanted to be like, and indeed he tries to model his heroic character on how he perceived the old Kurono would have acted. Kurono, meanwhile, has become a bitter, self-centered JerkAss as he grew up, but his time with Kato (and the experiences he goes through) eventually bring back his old badass self (ironically by him recursively trying to model himself on Kato).
* ChickMagnet: A good amount of girls fall for him. Such examples include Sei, Tae, Reika, as well as some others.
* DeathByAdaptation: In ''Gantz: O,'' he dies before Kato even joins the group.
* DesignatedHero: Starts off as one, a selfish and mean-spirited teenager obsessed with sex and not much else. His experiences with Gantz (as well as positive influence from Kato) set him on the path to becoming a more mature, heroic person.
* TheDeterminator: He's horribly outclassed, but his will to survive is strong enough that it doesn't matter.
* DrivenToSuicide: Averted, but it was a very near case. After [[spoiler:Tae was killed,]] Kurono spent some time just shooting himself with the gun until his suit started oozing.
* HopelessSuitor: To Kishimoto, who is firmly attracted to Kato and ignores his advances.
* JerkWithAHeartOfGold: 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.
* KidHero: He's fifteen at the beginning of the manga.
* TheLancer --> TheHero: Begins the series completely dependent on Kato's leadership, but grows into a capable leader himself over time.
* LovableSexManiac: Though, the 'loveable' is disputed among fans.
* LoveHurts: His crush on Kishimoto ends badly for all involved on multiple levels.
* MagneticHero: 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.
* MaleFrontalNudity: There's a very graphic closeup of his erect penis in chapter 168.
* MrFanservice: Probably the only male Seinen protagonist seen nude this frequently.
* OfficialCouple: With Tae.
* OurHeroIsDead: [[spoiler:Kurono gets killed in a fight with vampires, although it doesn't take that much (in story) time to get him revived.]]
* OrdinaryHighSchoolStudent
* TheProtagonist: ''Gantz'' is focused on his (un-)life as he gets sucked into the world of alien hunting.
* PlayingAgainstType: Creator/ChrisAyres 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?
%%* SurvivalMantra
* TechnicianVsPerformer: The Performer to Kato and Izumi's Technician.
* TookALevelInBadass: In the beginning, Kurono is just a selfish and pervert teenage boy, but the [[spoiler:death of all his friends]] and the constant danger eventually turns him into a survival especialist and a competent leader for the tokyo team.
* TookALevelInKindness: Along with TookALevelInBadass.
* TheUnfavorite: 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.
* WantsAPrizeForBasicDecency: Before CharacterDevelopment, Kurono was very much like this, shelthering and taking care of Kishimoto with hopes of potential sexual favors in return.

%%* BadassNormal
%%* BackFromTheDead
* BewareTheNiceOnes / GoodIsNotSoft: 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.
* BerserkButton: Never pratice violence against weak and/or undefended people or he will beat the crap out of you.
* BigBrotherInstinct: He is very protective of his little brother.
* CartwrightCurse: 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.
* ChronicHeroSyndrome: 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.
* CombatPragmatist: In spite of being a very NiceGuy, Kato will fight dirty to prevent loss of life.
%%* TheDeterminator
%%* {{Deuteragonist}}
* GoodIsNotDumb: 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.
* GuileHero: While he at first comes off as a delinquent turned WideEyedIdealist, Kato is shown to be a particularly good liar when he has to be and is even skilled at manipulating fights to his advantage.
%%* TheHeart
* HeroWorshipper: He had a big admiration for Kurono back when they were kids, which lasted after many years of being apart, to Kurono's surprise.

* IdealHero: The character that is closer to this trope in the series as a whole.
%%* TheLancer --> TheHero
* MrFanservice: A tall, well-toned guy with a great personality who of course frequently wears the skin tight Gantz suit.
* HonorBeforeReason: More often than not.
* ReluctantWarrior: 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 HeroicBlueScreenOfDeath and break down crying every time, though he still personally tends to almost always at least ''try'' to use the capture/TeleportGun whenever possible as opposed to one of the "ludicrous gibs" type, and risking himself to save others is one of his defining character traits.
* TokenGoodTeamMate: 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.
%%* OrdinaryHighSchoolStudent
* PromotionToParent: 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.

* AdaptationalHeroism: While he's still an asshole in ''Gantz: O,'' the only person he actually kills is a thug who threatened him. Granted, Nishi provoked the argument that led to the incident in the first place.
* AxCrazy: After his classmates [[BullyingADragon throw him out the window of their classroom]] (on the second story of the school), he comes back [[spoiler:and slaughters the entire class except for one girl because she was nice to him]].
* BackFromTheDead: He gets killed in the second arc and much later Kurono revives him in hopes he can provide more information about Gantz.
* ConflictBall: At the end of the first mission, it gets revealed that Nishi is the most experienced of the team, having been taking part in the missions for a year now. By extension, he has the most knowledge on how the missions work, but intentionally holds back on relaying anything to his teammates since [[IWorkAlone he only cares about getting points for himself.]]
* DirtyCoward: His recurring strategy is to stay invisible for most of the game and kill the alien once it's done with the rest of the party.
* EvilGloating: [[spoiler:[[http://www.mangareader.net/gantz/365/5 He sure seems proud of trying to off Tae in front of Kei's eyes.]]]]

* EyeScream: [[spoiler: Nishi, when he is killed by Suzuki Seiji]]
* FreudianExcuse: It's never explicitly stated, but considering he was [[spoiler: thrown out of several-storey window by bullies he refused to back down against in an attempt to kill him. (Notably, when the bullies try to cover things up]] ""his entire class goes along with it.""), it's fairly freaking unlikely that his life is rosy, by any definitions of the term.
* ImprobableAge: Already a sociopathic murderer at ''14''.
%%* IneffectualLoner
%%* {{Jerkass}}
* JerkWithAHeartOfJerk: 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.
* JerkAssHasAPoint 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 [[spoiler: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.]]
* KilledOffForReal: [[spoiler: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.]]
* LackOfEmpathy: Doesn't hesitate to kill anyone or feel sorry for the frequent massacres at the missions.
* NotSoDifferent: He does that with Kei in the fourth episode.
%%* OrdinaryHighSchoolStudent
%%* PsychoForHire
* {{Sadist}}: He tortured small animals when she was a child.
* SerialKiller: 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.
* SlasherSmile: [[spoiler:Boy howdy, does he ever sport one in chapters 364 and 365.]]
%%* TheSocialDarwinist
* TheSociopath: 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.
* SociopathicHero: Nishi is a sadistic teenager that doesn't give a damn about who will survive or who die during the missions and was no problems with killing living beings, be it animals, humans or aliens. However, he does help the good guys, at least most of the time.
* VillainousBreakdown: 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.
* TokenEvilTeamMate: Aside from Izumi and the ocassional rapists or {{jerkass}}es recruited by Gantz, he is the most notably evil.
* TroublingUnchildlikeBehavior: ''He's only in eighth grade!''
* TeensAreMonsters: an AxCrazy {{Sociopath}} by 14 years of age.
* {{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.
** This is especially amusing as he appears to consider himself to be a BloodKnight with NervesOfSteel.
* YoungerThanTheyLook: 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.

* AntiHero: ClassicalAntihero
* BadassNormal: Even without the suit, Kurono is a capable fighter.
%%* BackFromTheDead
* BecomingTheMask: The whole reason he originally went out with Tae was because of a penalty game.
* {{Bishonen}}: Especially in comparison to the generally very ugly rest of the cast, Kurono is small and slim with a boyish face.
* ButtMonkey: Outside of missions.
* CharacterDevelopment: Goes from a man who's only really concerned about himself and sex. To a Badass, risking life and limb for someone he loves.
* CharacterRerailment: Possible in-universe example- when Kurono and Kato first arrive at the Gantz room, Kato reminisces about the way that, when they ran together as kids, Kurono was a fearless, unstoppable badass that Kato admired and wanted to be like, and indeed he tries to model his heroic character on how he perceived the old Kurono would have acted. Kurono, meanwhile, has become a bitter, self-centered JerkAss as he grew up, but his time with Kato (and the experiences he goes through) eventually bring back his old badass self (ironically by him recursively trying to model himself on Kato).
* ChickMagnet: A good amount of girls fall for him. Such examples include Sei, Tae, Reika, as well as some others.
* DeathByAdaptation: In ''Gantz: O,'' he dies before Kato even joins the group.
* DesignatedHero: Starts off as one, a selfish and mean-spirited teenager obsessed with sex and not much else. His experiences with Gantz (as well as positive influence from Kato) set him on the path to becoming a more mature, heroic person.
* TheDeterminator: He's horribly outclassed, but his will to survive is strong enough that it doesn't matter.
* DrivenToSuicide: Averted, but it was a very near case. After [[spoiler:Tae was killed,]] Kurono spent some time just shooting himself with the gun until his suit started oozing.
* HopelessSuitor: To Kishimoto, who is firmly attracted to Kato and ignores his advances.
* JerkWithAHeartOfGold: 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.
* KidHero: He's fifteen at the beginning of the manga.
* TheLancer --> TheHero: Begins the series completely dependent on Kato's leadership, but grows into a capable leader himself over time.
* LovableSexManiac: Though, the 'loveable' is disputed among fans.
* LoveHurts: His crush on Kishimoto ends badly for all involved on multiple levels.
* MagneticHero: 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.

* TheUnfavorite: 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.
* WantsAPrizeForBasicDecency: Before CharacterDevelopment, Kurono was very much like this, shelthering and taking care of Kishimoto with hopes of potential sexual favors in return.

* GuileHero: While he at first comes off as a delinquent turned WideEyedIdealist, Kato is shown to be a particularly good liar when he has to be and is even skilled at manipulating fights to his advantage.
%%* TheHeart
* HeroWorshipper: 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.
* IdealHero: The character that is closer to this trope in the series as a whole.
%%* TheLancer --> TheHero
* MrFanservice: A tall, well-toned guy with a great personality who of course frequently wears the skin tight Gantz suit.
* HonorBeforeReason: More often than not.
* ReluctantWarrior: 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 HeroicBlueScreenOfDeath and break down crying every time, though he still personally tends to almost always at least ''try'' to use the capture/TeleportGun whenever possible as opposed to one of the "ludicrous gibs" type, and risking himself to save others is one of his defining character traits.
* TokenGoodTeamMate: 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.
%%* OrdinaryHighSchoolStudent
* PromotionToParent: 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.

* PrettyFreeloaders: Deconstructed, since Kurono's {{UST}} and feelings of EntitledToHaveYou (Type B) soon drives her back out onto the streets.
%%* SacrificialLion
* SoBeautifulItsACurse: If she had a point for every time she was sexually assaulted she'd have been free a long time ago.
* StupidSacrifice: 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.
* TheUnfairSex: Kishimoto chastises Kurono for his more cowardly traits, including hiding behind her when Nishi pulls a gun on her. He internally snarks that [[{{Hypocrite}} she does the same when it comes to looking for Kato to protect her]].
* {{UST}}: Kishimoto is the source of this for [[HopelessSuitor Kurono]] and in turn pines for Kato.
* WhatHappenedToTheMouse: The Kishimoto who Kurono and Kato loved and lost was a clone. The real Kishimoto survived her suicide attempt [[spoiler: and later, the alien invasion, living to the end of the series.]]

->'''Voiced by:''' Masahito Yabe (series), Tomohiro Kaku (movie) (Japanese), Creator/ChrisPatton (series), Creator/KyleMcCarley (movie) (English)
----
* AdaptationalAttractiveness: Quite creepy looking in the manga, but a more conventionally attractive (yet still creepy) {{Bishonen}} in the anime. He becomes better looking later on in the manga as well, making this a case of ProgressivelyPrettier. Also the movie casted Hongo Kanata to play him.
* AdaptationalHeroism: While he's still an asshole in ''Gantz: O,'' the only person he actually kills is a thug who threatened him. Granted, Nishi provoked the argument that led to the incident in the first place.
* AxCrazy: After his classmates [[BullyingADragon throw him out the window of their classroom]] (on the second story of the school), he comes back [[spoiler:and slaughters the entire class except for one girl because she was nice to him]].
* BackFromTheDead: He gets killed in the second arc and much later Kurono revives him in hopes he can provide more information about Gantz.
* ConflictBall: At the end of the first mission, it gets revealed that Nishi is the most experienced of the team, having been taking part in the missions for a year now. By extension, he has the most knowledge on how the missions work, but intentionally holds back on relaying anything to his teammates since [[IWorkAlone he only cares about getting points for himself.]]
* DirtyCoward: His recurring strategy is to stay invisible for most of the game and kill the alien once it's done with the rest of the party.
* EvilGloating: [[spoiler:[[http://www.mangareader.net/gantz/365/5 He sure seems proud of trying to off Tae in front of Kei's eyes.]]]]
* EvilLaughter: [[spoiler:[[http://www.mangareader.net/gantz/365/3 Sweet Jesus, does he find Kei's Heroic BSOD hilarious.]]]]
* EyeScream: [[spoiler: Nishi, when he is killed by Suzuki Seiji]]
* FreudianExcuse: It's never explicitly stated, but considering he was [[spoiler: thrown out of several-storey window by bullies he refused to back down against in an attempt to kill him. (Notably, when the bullies try to cover things up]] ""his entire class goes along with it.""), it's fairly freaking unlikely that his life is rosy, by any definitions of the term.
* ImprobableAge: Already a sociopathic murderer at ''14''.
%%* IneffectualLoner
%%* {{Jerkass}}
* JerkWithAHeartOfJerk: 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.
* JerkAssHasAPoint 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 [[spoiler: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.]]
* KilledOffForReal: [[spoiler: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.]]
* LackOfEmpathy: Doesn't hesitate to kill anyone or feel sorry for the frequent massacres at the missions.
* NotSoDifferent: He does that with Kei in the fourth episode.
%%* OrdinaryHighSchoolStudent
%%* PsychoForHire
* {{Sadist}}: He tortured small animals when she was a child.
* SerialKiller: 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.
* SlasherSmile: [[spoiler:Boy howdy, does he ever sport one in chapters 364 and 365.]]
%%* TheSocialDarwinist
* TheSociopath: 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.
* SociopathicHero: Nishi is a sadistic teenager that doesn't give a damn about who will survive or who die during the missions and was no problems with killing living beings, be it animals, humans or aliens. However, he does help the good guys, at least most of the time.
* VillainousBreakdown: 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.
* TokenEvilTeamMate: Aside from Izumi and the ocassional rapists or {{jerkass}}es recruited by Gantz, he is the most notably evil.
* TroublingUnchildlikeBehavior: ''He's only in eighth grade!''
* TeensAreMonsters: an AxCrazy {{Sociopath}} by 14 years of age.
* {{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.
** This is especially amusing as he appears to consider himself to be a BloodKnight with NervesOfSteel.
* YoungerThanTheyLook: 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.

--> ''Izumi'': [[spoiler: (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."
* AxCrazy: 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'' '''''[[CrossesTheLineTwice dressed as a Black Man]]'''''.
