History Characters / GANTZ

* CloningBlues: 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.

* [[Characters/GantzOthers Others]][[note]]Civilians, Vampires[[/note]]

* AmbiguouslyHuman: Their origin is not explained, except for the fact that it was something to do with nano-machines. The fact that they see the Gantz's hunter as enemies indicates that these machines may have alien origin.
* TheAnticipator: Downplayed. They have technology which allow them to see the Gantz's hunters even when they are invisible, it doesn't change the fact they are caught by surprise a few times.
* DaywalkingVampire: It's not the sunlight that is lethal to them, so they have some appearences during daytime.

* OurVampiresAreDifferent: They gain vampirism through an infection with nano-machines which creates a strange sing in their backs, sunlight doesn't affect them but artificial light does and there's no mention of they needing to drink blood to survive, although some vampires are shown found of [[IAmAHumanitarian cannibalism]].

* VillainDecay: They stop being a treat after the Nurarihyon Mission and are almost completely forgetten during the Katastrophe arc. Justified considering that both Izumi and Kei Kurono killed a lot of them and Host Samurai and Kill Bill are probably the last of their kind.

[[folder:Aliens]]

!Green Onion Aliens

* AlienBlood: Green alien blood.
* BadassLongcoat: Onion Alien's father.
* BaitAndSwitchBoss: The Onion Alien is the only one listed as a target. His father arrives ''right'' after the team kills him, and turns out to be a significantly worse threat.
* BenevolentAlienInvasion: The Onion Alien and his father don't seem to be hurting or planning to hurt anyone until the Gantz Hunters find them. Though, the father is capable of serious damage if provoked.
* TheBerserker: The father after [[spoiler: his son is brutally executed.]]
* BerserkerTears: A haunting villainous example.
%%* BloodSplatteredWarrior
* DescriptivelyNamedSpecies: They're green aliens who love green onions.
* FirstContact: The first aliens encountered in the series.
* HumanoidAlien: Their heads are about the only thing not standard-human-shaped.
* InnocentAliens: Appear to be living peacefully apart from humanity.
* InscrutableAliens: It's hard for Kato to explain himself to the enraged alien with a heavy language barrier between them.
%%* {{Invisibility}}
* LightningBruiser: Onion Alien's father.
* LittleGreenMen: 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.
* NighInvulnerability: 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.
* PapaWolf: The Onion Alien's father is understandably enraged when the team kills his son, and proceeds to make his anger known in great detail.
%%* RevengeBeforeReason
* ShootTheDog: 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.
* StarfishLanguage: Whatever the father alien is speaking, it's nowhere near a human language. Oddly, his son can speak Japanese just fine.
* StarterVillain: Despite the terror Kurono, Kato, and Kishimoto endured during this mission, the Onion Aliens are nothing compared to what they face later.
* SuperStrength: The father quite literally tears several of the team apart with his bare hands.
%%* SympathyForTheDevil
%%* WolverineClaws

!Tanaka Aliens

* AlienAnimals: Giant birds.
%%* AliensAreBastards
%%* FeatheredFiend
%%* {{Flight}}
* HumanOutsideAlienInside: Fails at the "human outside" part so bad that they must remain invisible even in disguise.
* InnocentAliens: 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.
%%* {{Invisibility}}
* MakeMeWannaShout: Their primary attack.
* NoCelebritiesWereHarmed: They all wear cyborg disguises resembling a popular Japanese celebrity.
%%* RazorWings
%%* StarterVillain
%%* WingedHumanoid
* TheWorfEffect: This mission proved that AnyoneCanDie 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

* AbsurdlySharpBlade: The swords which 1000 Arms possesses are capable of cutting through flesh, bone, the Gantz suits, and even stone.
* BewareMyStingerTail: Which allows 1000 Arms to finish off [[spoiler:Kato even after it has been mortally wounded.]]
%%* BizarreAlienBiology
* BlingOfWar: All of their statue disguises can count as this, especially 1000 Arms.
* BloodKnight: 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.
* BrainFood: A couple of these aliens eat the brains of their victims.
* BreakTheHaughty: 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 AnArmAndALeg, and finally he finds out that he is the mission's SoleSurvivor.
* DefiantToTheEnd: 1000 Arms kills Kato during its last moments... after it has already been decapitated
* DiscOneFinalBoss: 1000 Arms is this for Kato.
* DualWielding: The 1000 Arms statue carries two swords.
* EnergyWeapon: 1000 Arms has an ornament which can project deadly lasers.
* {{Foreshadowing}}: [[spoiler: 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.]]
* HealingFactor: 1000 Arms has one, via an ornament it possesses which seems to [[TimeMaster reverse any damage done to it]] so long as the ornament remains in tact.
* HeroKiller: 1000 Arms kills [[spoiler:Kato]].
* HoistByHisOwnPetard: When Sei kicks the acid vial out of 1000 Arms' hand, melting half of its statue disguise and its TimeMaster ornament.
* HollywoodAcid: 1000 Arms makes use of acid to fight, which viciously melts Kurono's arm and leg when he gets too close while attacking it.
* HumanOutsideAlienInside: Buddhist statue outside, lizard alien inside.
* InnocentAliens: 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.
%%* {{Invisibility}}
%%* LightningBruiser
* MultiArmedAndDangerous: 1000 Arms' statue disguise, and possibly all of them in their true form.
* OneWingedAngel: 1000 Arms
* PyrrhicVictory: 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.
* RoaringRampageOfRevenge: 1000 Arms does not respond well to the puny humans who eradicated its companions.
* ShockwaveClap: The larger statues can do this.
* ShootTheDog: The entire mission is one long Shoot the Dog. Becomes a literal example, when one of the statues smashes the TeamPet dog's head without any warning.
%%* SuperSpeed
%%* SuperStrength
* StarterVillain: The most traumatizing starter villains yet.
* SymbioticPossession: 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.
%%* SympathyForTheDevil: Though, we sympathize a lot more with the Tokyo Team, of course, since they are severely disadvantaged and out of their depth at this point.
* TheWorfEffect: 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.
%%* ThisIsUnforgivable

!Shorty Aliens

%%* AlasPoorVillain
* AlienBlood: In the video game adaptation they have purple blood.
* ArrogantKungFuGuy: All of them. Except they all can back up their arrogance.
* AwesomenessByAnalysis: One of their key weapons.
** "I know your fighting style. I will not fall for any of your tricks."
* BadassBoast: "First, I will defeat you. Then, I will kill you. I will never forgive you for what you have done."
* BreakTheHaughty: They finish what The Buddhist Temple Aliens started as far as convincing Kurono that he isn't as cool as he thinks.
* CharlesAtlasSuperPower: Gantz describing them as "Strong" doesn't quite cut it.
* ClimaxBoss: The SoleSurvivor Shorty Alien ultimately winds up as this to Kurono. It ends up tacking Kurono into the real world and slaughters most of his classmates in retribution for Kurono killing his comrades. This ends up being a major catalyst towards Kurono's CharacterDevelopment of legitimate heroism.
%%* {{Determinator}}: "Strong will."
* FaceDeathWithDignity: The last one only stands up straight and glowers at Kurono before it explodes.
* HumanOutsideAlienInside: 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.
%%* HumanoidAliens
* HyperAwareness: "I can see in to your heart." It's true in more ways than one.
%%* InASingleBound
* LittleGreenMen: But exotic-looking and highly lethal.
* MesACrowd: They all look exactly alike, though they may not be clones.
* NoHoldsBarredBeatdown: Their specialty.
%%* SmugSuper
* RoaringRampageOfRevenge: In the mission which they were supossed to be slain, Kurono left one alive because the time was up and he was the only hunter sent to that mission. The surviving one tracked down Kurono and killed all of his classmates (except Tae and Izumi) in retaliation.
* SuperStrength: Can tear normal humans to pieces with just their hands, and are all skilled fighters.
* SympathyForTheDevil
%%* {{Telepathy}}
* ThisIsUnforgivable: A group reaction when Kurono kills the first one.
* WingsDoNothing: If those even are wings on their backs, they never seem to use them.

!Kappe Aliens

* AlienAnimals: Well, dinosaurs.
%%* AliensAreBastards
* TheBigGuy: The Kappe Alien, though it started out as a little guy.
* EliteMooks: The Velociraptors and smaller Brachiosaurus.
* EvilVersusEvil: The T-Rexes and Triceratops' don't get along and end up fighting over who kills Izumi.
* ExtraEyes: The Horned Brachiosaurus spontaneously grows hundreds of eyes on its underbelly when Kurono tries to sneak attack it from below.
* GiantMook: The T-Rexes and Triceratops.
* GentleGiantSauropod: Averted with the Brachiosaurus.
* HumanoidAliens: The Kappe Alien.
* IntelligentGerbil: Many are disguised as prehistoric dinosaurs, despite the fact that they can shift sizes, stand upright, develop fists, and breathe fireballs.
* NightmareFuelStationAttendant: The Kappe Alien looks kind of cute and harmless at first, until you realize it controls the dinosaur aliens, has SuperStrength, and can turn into a hideous giant.
* OutrunTheFireball: Kurono literally has to do this when he's being chased by the T-Rexes, who shoot fireballs out of their mouths.
* PsychopathicManchild: 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.
* RaptorAttack: The Velociraptors, of course.
* ShrinkingViolet / TheBerserker: The Kappe Alien is pretty timid normally, but is insatiable when pissed off.
* SizeShifter: The angrier these aliens get, the bigger they get.
* ThisIsUnforgivable: The Horned Brachiosaurus, who is apparently the mother of the other dinosaurs, reacts this way when it is the only one left.
* TheWorfEffect: Just as The Kappe Alien grows to an enormous size, becoming a OneWingedAngel, it is easily cut in half from behind by Izumi.
* WouldHitAGirl: 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

* AbsurdlySharpBlade: Their massive scythes.
%%* AliensAreBastards
* AntiClimax: Despite their enormous size, powerful weapons, and menacing appearance, they are taken down quite easily.
%%* AttackOfThe50FootWhatever
%%* EldritchAbomination
* {{Expy}}: Of The Ringwraiths from The Lord of The Rings.
* {{Jerkass}}: Not particularly subtle, they are seen trying to kill any humans they find.
* LargeAndInCharge: Giant demon knights on equally giant horses.
* SinisterScythe: Their WeaponOfChoice.

!Oni Aliens

%%* AliensAreBastards
* BoldlyComing: 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.
* DemonLordsAndArchDevils: The leaders seem to be these.
* EldritchAbomination: 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.
* HornyDevils: Rape is as commonplace as murder for these guys.
* HumanAliens: They look like regular humans... [[SubvertedTrope at first]].

* LargeHam: Just about all of them.
* LightningBruiser: The main demon, who actually has a lightning based power as well.
%%* LovecraftianSuperPower
%%* NightmareFetishist: All of them.
%%* OurDemonsAreDifferent
* {{Petrification}}: The leader that fights Kaze can turn others into stone and can armor himself in stone as well.
* {{Shapeshifter}}: All of them, but one of the leaders is especially... gifted.
* ShockAndAwe: The Lightning demon.
* SmallNameBigEgo: The lesser demons.
%%* SmugSmiler
%%* SmugSuper
* VoluntaryShapeshifting: Leads to many {{Squick}} moments.
* WellIntentionedExtremist: Though they are far from being Noble Demons, their motivation seems to be, in part, to eliminate the threat to aliens hiding out on earth.

!Nurarihyon[=/=]Osaka Aliens

%%* AliensAreBastards
* AttackOfTheFiftyFootWhatever: Gyuuki, the ginormous minotaur-lobster thing that ''isn't even the final boss.''
* AttackItsWeakPoint: The only known way to kill Nurarihyon is to hit him when his back is turned. Easier said then done...
%%* BizarreAlienBiology
* CloudCuckoolander[=/=]PsychopathicManchild: Nurarihyon observes attacks made against it as if it were observing someone challenging it at chess.
* EldritchAbomination: A whole city district full of them, led by one of the biggest ones ever.
* EvilCounterpart: The samurai alien couple to Host Samurai and Kill Bill. Or rather alien counterparts to the vampires.
* EyeBeams: 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.
* FromASingleCell: Nurarihyon's HealingFactor is ''off the chain.'' It doesn't matter how many pieces you bash it into because even the pieces are dangerous.
%%* HeroKiller: Nurarihyon.
* IntelligentGerbil: More than a few are these.
* KnightOfCerebus: Despite the number of atrociously difficult aliens seen throughout, Nurarihyon takes things to a whole new level of fear and hopelessness.
* LightningBruiser: Nurarihyon lives and breaths this trope. To give you a sense of how powerful this alien is, after he assumes his final form he incapacitates 3 members of the Tokyo Gantz team in the blink of an eye and proceeds to kill the strongest member of the Osaka Gantz team offscreen. Hell, It takes Sakata's overloaded psychic abilities to temporarily '''hold him back '''.
%%* LovecraftianSuperpower
* MaleGaze: Whether Nurarihyon has this himself or merely shapeshifts into mutated buxom women to distract his enemies is debatable.
* ManOfWealthAndTaste: Though they are bizarre monstrosities, Nurarihyon, its two powerful friends, and the samurai alien couple see themselves as this.
%%* MonsterLord
* NighInvulnerability: Nurarihyon.
* NightmareFuelStationAttendant: Nurarihyon and its two companions are this to the rest of the chaotic monsters in Osaka.
%%* OneWingedAngel[=/=]PhysicalGod: Nurarihyon itself.
* OurMonstersAreWeird
* SherlockScan: 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.
* SmugSuper: Nurarihyon, and the rest take after it.
* SoftSpokenSadist: 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.
* SympathyForTheDevil: Though most are violent and predatory, a few are simply defending themselves from or at the mercy of the malicious Osaka Team.
* VoluntaryShapeshifting: Nurarihyon is perhaps the most disturbing example of this trope.
* WretchedHive: Osaka is this thanks to these aliens.
* {{Yokai}}: A deliberate running theme with this lot.

!Renaissance Statue Aliens

%%* AliensAreBastards
* BloodKnight: They all appear to just love destroying humans, especially humans who try to fight like the Gantz teams.
* ColdBloodedTorture: Poor Suzuki and Inaba.
* CurbStompBattle: The biggest one yet.
%%* DeathFromAbove
* DiscOneFinalBoss: [[spoiler:An extended vacation would have been much appreciated after this mission. Instead, they get TheEndOfTheWorldAsWeKnowIt.]]
* FlyingBrick: An extreme villainous example. These statues manage to be more destructive than almost any other aliens encountered thus far.
%%* ForTheEvulz
%%* FragileSpeedster
* HalfTheManHeUsedToBe: Half of Kurono's torso is shredded as he kills this round's KnightOfCerebus. Luckily, he is tranferred out in time.
* HeroKiller: Practically a sport.
* {{Jerkass}}: Sadistic pricks, every one of them.
* OurMonstersAreWeird
* PintSizedPowerhouse: The smiling cupids flying around kicking people's heads off. And snapping the Gantz swords between their toes.
%%* SuperSpeed
%%* SuperStrength
* WorldsStrongestMan: 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

* TheAce: Eeva Gund, the God of War appears to be this among the Giant Alien Army...
** BrokenAce: ...But is probably this after the Giants have been defeated and his brother Oltra was killed by Kei.
* AliensAreBastards: 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.
* AttackOfThe50FootWhatever: Gigantic as their name implies.
* {{Bishonen}}: The God of War is a bishonen giant.
* BizarreAlienBiology: Subverted somewhat. They look very much like humans, but are gigantic in comparison, have four eyes, and the males apparently have multiple penises.
* BoomHeadshot: [[spoiler: How Kurono manages to finally kill the God of War.]]
* ButForMeItWasTuesday: Earth is definitely not the first planet they've invaded and it shows. [[spoiler: Though, it may be the last.]]
* CallBack: [[spoiler: This was a callback to when Kurono killed a giant Buddhist Temple alien in the same manner earlier in the series.]]
* CharlesAtlasSuperPower: They have it, and their size surely helps.
* ColonyDrop: Eeva Gund threatens to do this to the whole world with the mothership if Kurono doesn't come to fight him in a duel.
* CrazyPrepared: 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. [[spoiler: Not that it helps them win in the end.]]
* EliteMooks: Their exploding, armored lizard minions.
* TheEndOfTheWorldAsWeKnowIt: What they bring about.
* GeniusBruiser: They are smart as well as strong.
* HumanoidAliens: Despite their gigantic average size, the two extra small eyes (one in each of their head's temples) and somewhat bizarre genitals, they look very much like humans. Also, besides their appearances, their society (at least the one inside the spaceship) is almost exactly like the modern human societies in urban areas. But, ironically, most of them just see the humans as exotic animals and nothing more.
* HumongousMecha: They have them as part of their technology.
* {{Jerkass}}: Many, though not all of them, so AlwaysChaoticEvil is averted.
* KilledOffForReal: [[spoiler:Their entire population by the end of the series, bad and good.]]
* LackOfEmpathy: To parallel humanity's own lack of empathy towards species we view as being beneath us.
* LightningBruiser: They're all capable of this, but The God of War especially.
* NamesToRunAwayFromReallyFast: The strongest Giant is called the God of War by his people.
* RapePillageAndBurn: What they do to most of Earth.
* TheRemnant: [[spoiler:Their numbers are severely depleted after their apparent defeat.]]
* ToServeMan: They collect and slaughter humans like cattle and serve them as delicacies.
* SmugSuper: They're not very modest about their power.
* SophisticatedAsHell: Able to speak like this, which somewhat emphasizes their similar nature.
* SufficientlyAdvancedAliens: They're powerful and technologically advanced enough to qualify as this.
* WorthyOpponent: The God of War and Giants in general, seem to see Kurono as this.

!Mothership Aliens

%%* AliensAreBastards
* AlienAnimals: Kurono and Tei happen upon a literal zoo full of them.
* BizarreAlienBiology: With extra emphasis on the word "bizarre."
* BodyHorror: Some of these aliens can explode into a cloud of floating light spores. [[spoiler: 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.]]
%%* EldritchAbomination
%%* InsectoidAliens: Lots.
* MightyGlacier: 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.
%%* OurMonstersAreWeird
%%* ViralTransformation: Pandora's Box.
* WretchedHive: What they inhabit on The Mothership.

!Room of Truth Aliens

* AbusivePrecursors: They most definitely came into being before humanity, and they aren't very kind beings to say the least.
* AFormYouAreComfortableWith: 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.
* AliensAreBastards: Fitting that the most powerful ones would also be the biggest bastards.
* ButForMeItWasTuesday: Their reaction to pretty much the entire series and everything the characters have been through.
* BrownNote: When humans see them for the first time, they [[TearsOfBlood cry blood]]. However, this effect doesn't last longer and doesn't seem to be too harmful.
* EldritchAbomination: They are insanely powerful (and in a Lovecraftian way), [[ThePowersThatBe Powers That Be-style]] non-humanoid (despite the form they take) aliens.
* {{Expy}}: They seem to be a freaky combination of the aliens from Contact, the Engineers/Space Jockeys, and the Monolith.
* GoodIsNotNice: Technically, [[spoiler: 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 LetsYouAndHimFight."
* GreaterScopeVillain: They are responsible for humanity's discovery and utilization of the Gantz technology.
* {{Jerkass}}: They don't care ''at all'' about "lesser" lifeforms, and they only helped humanity because they felt like it. If they'd wanted to, they would've simply let the Giants destroy the Earth.
* KarmaHoudini: They get away with all the havoc and misery they are responsible for, because there is apparently no one powerful enough to stop them. As they created the technology used by Gantz and the Hunters, and the fact they can make people explode if angered, it would be impossible to fight them.
* KickTheDog: When they [[spoiler: resurrect Kishimoto, Sei, Suzuki, and Reika and then immediately destroy them]] just to prove to Clone!Kei that human life has no value. They later [[spoiler:kill him when he attacks them, horrifying Masaru and outright making him cry.]]
* LackOfEmpathy: They tell the disheartened, battle-scarred Gantz Hunters that humans are no different from ants and that everything they do is totally meaningless.
* LovecraftianSuperpower: It seems that every power of theirs is this kind of power.
* LudicrousGibs: Their favorite method of execution [[spoiler: as Clone!Kei found out personally.]]
* MrExposition: Their sole purpose in the story is to wrap up the loose ends, mainly concerning the origins of Gantz and the reason why the Giant Aliens attacked Earth.
* NayTheist: They outright say that God doesn't exist, and though they acknowledge the existence of souls, they don't see anything special about it.
* TheOmniscient: Their knowledge doesn't seem to have bounds.
* PhysicalGod: Powerful enough to be considered this.
* ThePowersThatBe: A bad version of this. They pull the strings.
* TheReasonYouSuckSpeech: They deliver a cold one to humanity as a whole. Even Masaru is left in tears.
* StrawNihilist: They make it their goal to prove that human life has no real value when they KickTheDog, and justify it through being omniscient.
* SufficientlyAdvancedAlien: Perhaps the most sufficiently advanced aliens in the universe.
[[/folder]]


[[folder:Vampires]]

!In General
* AmbiguouslyHuman: Their origin is not explained, except for the fact that it was something to do with nano-machines. The fact that they see the Gantz's hunter as enemies indicates that these machines may have alien origin.
* TheAnticipator: Downplayed. They have technology which allow them to see the Gantz's hunters even when they are invisible, it doesn't change the fact they are caught by surprise a few times.
* DaywalkingVampire: It's not the sunlight that is lethal to them, so they have some appearences during daytime.
* LeftHanging: Not much about them is explained, even through they are the antagonists of an arc.
* OurVampiresAreDifferent: They gain vampirism through an infection with nano-machines which creates a strange sing in their backs, sunlight doesn't affect them but artificial light does and there's no mention of they needing to drink blood to survive, although some vampires are shown found of [[IAmAHumanitarian cannibalism]].
* SharpDressedMan: All of them wear suits.
* TreasureChestCavity: They can store pistols and even ''katanas'' in a hole in the palm of their hands.
* VillainDecay: They stop being a treat after the Nurarihyon Mission and are almost completely forgetten during the Katastrophe arc. Justified considering that both Izumi and Kei Kurono killed a lot of them and Host Samurai and Kill Bill are probably the last of their kind.

!Host Samurai/Hikawa

* AuthorityEqualsAsskicking: 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.
* BadassInANiceSuit: He's practically invincible on the battlefield. And, a well dressed one. He wears a black suit and tie.
* CombatPragmatist: He has no problem with fighting dirty if it means winning a fight.
* EmbarrassingNickname: "Host Samurai" is how Gantz refers to him, which "Kill Bill" finds amusing.
* EvilIsPetty: 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, [[EvenEvilHasStandards he loses interest in wiping them out.]]
* HeroKiller: [[spoiler: Kills Izumi, the series definitive AntiHero, and Kei, TheHero. Kei got better, and also a clone.]]
%%* {{Jerkass}}

* [[Characters/GantzOthers Others]]

[[folder:Osaka Team]]

!Tsuneo Nikaido, "Virgin-kun/The Nerd"

* ADayInTheLimelight: 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.
%%* BackFromTheDead
%%* BadassBystander
%%* BerserkerTears
%%* CrouchingMoronHiddenBadass
* DidYouJustPunchOutCthulhu: Using the Nurarihyon Alien's severed head to disintegrate several of monsters in its own brood.
* FishOutOfWater: 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.
* HeroWorshipper: Towards Masaru Kato.
* KilledOffForReal: [[spoiler:Decapitated by the God of War.]]
** [[spoiler: Except not because those killed in the final fight are revived although we never see them again. Why this is suddenly possible when it'd been established that Gantz can no longer revive people is never explained.]]
* TheLoad: More often than not, until he got used to the missions.
* NoNameGiven: The others never refer to him by name.

%%* DarkActionGirl: Tries to come off this way at first. It doesn't last long.
* HeroWorshipper: 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.
%%* HeroicSacrifice
* {{Irony}}: Of all the Osaka members, Anzu lives possibly the most morally ambiguous normal life. While most of the PsychoForHire 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.
* MoralityPet: Love for her son compels her to survive. Love for Kato compels her to be heroic.
* TheOathbreaker: [[spoiler: 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.]]

* BloodKnight: A subtle version.
* CombatPragmatist: 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.
* CruelAndUnusualDeath: [[spoiler:Apparently ripped apart by Nurarihyon. We only see that he's missing everything below his chest.]]
* CurbStompBattle: 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.
%%* DroppedABridgeOnHim
* TheGhost: 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.

* HumongousMecha: Pilots one when he first appears.
%%* InHarmsWay
%%* KilledOffForReal
* KnowWhenToFoldEm: 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? [[spoiler:(It doesn't save him this time, because the alien is a BloodKnight who wants to keep fighting him, but it's almost certainly how he survived so long in the first place.)]]

%%* UnflinchingWalk
* TheWorfEffect: [[spoiler: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.]]
* WorthyOpponent: Nurarihyon considers him to be something like this, claiming "he was fun" when confronted with Kaze's "predictable" martial arts. [[spoiler: It even abandons its fight with the Tokyo Team to hunt Oka throughout Osaka, and destroys several buildings in the process of killing him.]]

* LittleGreenMen: 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.
* NighInvulnerability: 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.
* PapaWolf: The Onion Alien's father is understandably enraged when the team kills his son, and proceeds to make his anger known in great detail.
%%* RevengeBeforeReason
* ShootTheDog: 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.
* StarfishLanguage: Whatever the father alien is speaking, it's nowhere near a human language. Oddly, his son can speak Japanese just fine.
* StarterVillain: Despite the terror Kurono, Kato, and Kishimoto endured during this mission, the Onion Aliens are nothing compared to what they face later.

%%* AliensAreBastards
%%* FeatheredFiend
%%* {{Flight}}
* HumanOutsideAlienInside: Fails at the "human outside" part so bad that they must remain invisible even in disguise.
* InnocentAliens: 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.

%%* BizarreAlienBiology
* BlingOfWar: All of their statue disguises can count as this, especially 1000 Arms.

* BrainFood: A couple of these aliens eat the brains of their victims.
* BreakTheHaughty: 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 AnArmAndALeg, and finally he finds out that he is the mission's SoleSurvivor.
* DefiantToTheEnd: 1000 Arms kills Kato during its last moments... after it has already been decapitated

* HumanOutsideAlienInside: Buddhist statue outside, lizard alien inside.
* InnocentAliens: 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.

* OneWingedAngel: 1000 Arms
* PyrrhicVictory: 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.
* RoaringRampageOfRevenge: 1000 Arms does not respond well to the puny humans who eradicated its companions.
* ShockwaveClap: The larger statues can do this.

* StarterVillain: The most traumatizing starter villains yet.
* SymbioticPossession: 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.
%%* SympathyForTheDevil: Though, we sympathize a lot more with the Tokyo Team, of course, since they are severely disadvantaged and out of their depth at this point.

* BreakTheHaughty: They finish what The Buddhist Temple Aliens started as far as convincing Kurono that he isn't as cool as he thinks.
* CharlesAtlasSuperPower: Gantz describing them as "Strong" doesn't quite cut it.
* ClimaxBoss: The SoleSurvivor Shorty Alien ultimately winds up as this to Kurono. It ends up tacking Kurono into the real world and slaughters most of his classmates in retribution for Kurono killing his comrades. This ends up being a major catalyst towards Kurono's CharacterDevelopment of legitimate heroism.
%%* {{Determinator}}: "Strong will."
* FaceDeathWithDignity: The last one only stands up straight and glowers at Kurono before it explodes.

* GiantMook: The T-Rexes and Triceratops.
* GentleGiantSauropod: Averted with the Brachiosaurus.
* HumanoidAliens: The Kappe Alien.
* IntelligentGerbil: Many are disguised as prehistoric dinosaurs, despite the fact that they can shift sizes, stand upright, develop fists, and breathe fireballs.
* NightmareFuelStationAttendant: The Kappe Alien looks kind of cute and harmless at first, until you realize it controls the dinosaur aliens, has SuperStrength, and can turn into a hideous giant.
* OutrunTheFireball: Kurono literally has to do this when he's being chased by the T-Rexes, who shoot fireballs out of their mouths.
* PsychopathicManchild: 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.
* RaptorAttack: The Velociraptors, of course.
* ShrinkingViolet / TheBerserker: The Kappe Alien is pretty timid normally, but is insatiable when pissed off.
* SizeShifter: The angrier these aliens get, the bigger they get.
* ThisIsUnforgivable: The Horned Brachiosaurus, who is apparently the mother of the other dinosaurs, reacts this way when it is the only one left.
* TheWorfEffect: Just as The Kappe Alien grows to an enormous size, becoming a OneWingedAngel, it is easily cut in half from behind by Izumi.
* WouldHitAGirl: 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.

* FromASingleCell: Nurarihyon's HealingFactor is ''off the chain.'' It doesn't matter how many pieces you bash it into because even the pieces are dangerous.
%%* HeroKiller: Nurarihyon.
* IntelligentGerbil: More than a few are these.
* KnightOfCerebus: Despite the number of atrociously difficult aliens seen throughout, Nurarihyon takes things to a whole new level of fear and hopelessness.
* LightningBruiser: Nurarihyon lives and breaths this trope. To give you a sense of how powerful this alien is, after he assumes his final form he incapacitates 3 members of the Tokyo Gantz team in the blink of an eye and proceeds to kill the strongest member of the Osaka Gantz team offscreen. Hell, It takes Sakata's overloaded psychic abilities to temporarily '''hold him back '''.
%%* LovecraftianSuperpower
* MaleGaze: Whether Nurarihyon has this himself or merely shapeshifts into mutated buxom women to distract his enemies is debatable.
* ManOfWealthAndTaste: Though they are bizarre monstrosities, Nurarihyon, its two powerful friends, and the samurai alien couple see themselves as this.
%%* MonsterLord
* NighInvulnerability: Nurarihyon.
* NightmareFuelStationAttendant: Nurarihyon and its two companions are this to the rest of the chaotic monsters in Osaka.
%%* OneWingedAngel[=/=]PhysicalGod: Nurarihyon itself.
* OurMonstersAreWeird
* SherlockScan: 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.
* SmugSuper: Nurarihyon, and the rest take after it.
* SoftSpokenSadist: 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.
* SympathyForTheDevil: Though most are violent and predatory, a few are simply defending themselves from or at the mercy of the malicious Osaka Team.
* VoluntaryShapeshifting: Nurarihyon is perhaps the most disturbing example of this trope.
* WretchedHive: Osaka is this thanks to these aliens.
* {{Yokai}}: A deliberate running theme with this lot.

!Renaissance Statue Aliens

%%* AliensAreBastards
* BloodKnight: They all appear to just love destroying humans, especially humans who try to fight like the Gantz teams.
* ColdBloodedTorture: Poor Suzuki and Inaba.
* CurbStompBattle: The biggest one yet.
%%* DeathFromAbove
* DiscOneFinalBoss: [[spoiler:An extended vacation would have been much appreciated after this mission. Instead, they get TheEndOfTheWorldAsWeKnowIt.]]
* FlyingBrick: An extreme villainous example. These statues manage to be more destructive than almost any other aliens encountered thus far.
%%* ForTheEvulz
%%* FragileSpeedster
* HalfTheManHeUsedToBe: Half of Kurono's torso is shredded as he kills this round's KnightOfCerebus. Luckily, he is tranferred out in time.
* HeroKiller: Practically a sport.
* {{Jerkass}}: Sadistic pricks, every one of them.
* OurMonstersAreWeird
* PintSizedPowerhouse: The smiling cupids flying around kicking people's heads off. And snapping the Gantz swords between their toes.
%%* SuperSpeed
%%* SuperStrength
* WorldsStrongestMan: 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

* TheAce: Eeva Gund, the God of War appears to be this among the Giant Alien Army...
** BrokenAce: ...But is probably this after the Giants have been defeated and his brother Oltra was killed by Kei.
* AliensAreBastards: 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.
* AttackOfThe50FootWhatever: Gigantic as their name implies.
* {{Bishonen}}: The God of War is a bishonen giant.
* BizarreAlienBiology: Subverted somewhat. They look very much like humans, but are gigantic in comparison, have four eyes, and the males apparently have multiple penises.
* BoomHeadshot: [[spoiler: How Kurono manages to finally kill the God of War.]]
* ButForMeItWasTuesday: Earth is definitely not the first planet they've invaded and it shows. [[spoiler: Though, it may be the last.]]
* CallBack: [[spoiler: This was a callback to when Kurono killed a giant Buddhist Temple alien in the same manner earlier in the series.]]
* CharlesAtlasSuperPower: They have it, and their size surely helps.
* ColonyDrop: Eeva Gund threatens to do this to the whole world with the mothership if Kurono doesn't come to fight him in a duel.
* CrazyPrepared: 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. [[spoiler: Not that it helps them win in the end.]]
* EliteMooks: Their exploding, armored lizard minions.
* TheEndOfTheWorldAsWeKnowIt: What they bring about.
* GeniusBruiser: They are smart as well as strong.
* HumanoidAliens: Despite their gigantic average size, the two extra small eyes (one in each of their head's temples) and somewhat bizarre genitals, they look very much like humans. Also, besides their appearances, their society (at least the one inside the spaceship) is almost exactly like the modern human societies in urban areas. But, ironically, most of them just see the humans as exotic animals and nothing more.
* HumongousMecha: They have them as part of their technology.
* {{Jerkass}}: Many, though not all of them, so AlwaysChaoticEvil is averted.
* KilledOffForReal: [[spoiler:Their entire population by the end of the series, bad and good.]]
* LackOfEmpathy: To parallel humanity's own lack of empathy towards species we view as being beneath us.
* LightningBruiser: They're all capable of this, but The God of War especially.
* NamesToRunAwayFromReallyFast: The strongest Giant is called the God of War by his people.
* RapePillageAndBurn: What they do to most of Earth.
* TheRemnant: [[spoiler:Their numbers are severely depleted after their apparent defeat.]]
* ToServeMan: They collect and slaughter humans like cattle and serve them as delicacies.
* SmugSuper: They're not very modest about their power.
* SophisticatedAsHell: Able to speak like this, which somewhat emphasizes their similar nature.
* SufficientlyAdvancedAliens: They're powerful and technologically advanced enough to qualify as this.
* WorthyOpponent: The God of War and Giants in general, seem to see Kurono as this.

!Mothership Aliens

%%* AliensAreBastards
* AlienAnimals: Kurono and Tei happen upon a literal zoo full of them.
* BizarreAlienBiology: With extra emphasis on the word "bizarre."
* BodyHorror: Some of these aliens can explode into a cloud of floating light spores. [[spoiler: 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.]]
%%* EldritchAbomination
%%* InsectoidAliens: Lots.
* MightyGlacier: 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.
%%* OurMonstersAreWeird
%%* ViralTransformation: Pandora's Box.
* WretchedHive: What they inhabit on The Mothership.

!Room of Truth Aliens

* AbusivePrecursors: They most definitely came into being before humanity, and they aren't very kind beings to say the least.
* AFormYouAreComfortableWith: 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.
* AliensAreBastards: Fitting that the most powerful ones would also be the biggest bastards.
* ButForMeItWasTuesday: Their reaction to pretty much the entire series and everything the characters have been through.
* BrownNote: When humans see them for the first time, they [[TearsOfBlood cry blood]]. However, this effect doesn't last longer and doesn't seem to be too harmful.
* EldritchAbomination: They are insanely powerful (and in a Lovecraftian way), [[ThePowersThatBe Powers That Be-style]] non-humanoid (despite the form they take) aliens.
* {{Expy}}: They seem to be a freaky combination of the aliens from Contact, the Engineers/Space Jockeys, and the Monolith.
* GoodIsNotNice: Technically, [[spoiler: 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 LetsYouAndHimFight."
* GreaterScopeVillain: They are responsible for humanity's discovery and utilization of the Gantz technology.
* {{Jerkass}}: They don't care ''at all'' about "lesser" lifeforms, and they only helped humanity because they felt like it. If they'd wanted to, they would've simply let the Giants destroy the Earth.
* KarmaHoudini: They get away with all the havoc and misery they are responsible for, because there is apparently no one powerful enough to stop them. As they created the technology used by Gantz and the Hunters, and the fact they can make people explode if angered, it would be impossible to fight them.
* KickTheDog: When they [[spoiler: resurrect Kishimoto, Sei, Suzuki, and Reika and then immediately destroy them]] just to prove to Clone!Kei that human life has no value. They later [[spoiler:kill him when he attacks them, horrifying Masaru and outright making him cry.]]
* LackOfEmpathy: They tell the disheartened, battle-scarred Gantz Hunters that humans are no different from ants and that everything they do is totally meaningless.
* LovecraftianSuperpower: It seems that every power of theirs is this kind of power.
* LudicrousGibs: Their favorite method of execution [[spoiler: as Clone!Kei found out personally.]]
* MrExposition: Their sole purpose in the story is to wrap up the loose ends, mainly concerning the origins of Gantz and the reason why the Giant Aliens attacked Earth.
* NayTheist: They outright say that God doesn't exist, and though they acknowledge the existence of souls, they don't see anything special about it.
* TheOmniscient: Their knowledge doesn't seem to have bounds.
* PhysicalGod: Powerful enough to be considered this.
* ThePowersThatBe: A bad version of this. They pull the strings.
* TheReasonYouSuckSpeech: They deliver a cold one to humanity as a whole. Even Masaru is left in tears.
* StrawNihilist: They make it their goal to prove that human life has no real value when they KickTheDog, and justify it through being omniscient.
* SufficientlyAdvancedAlien: Perhaps the most sufficiently advanced aliens in the universe.
[[/folder]]


[[folder:Vampires]]

!In General
* AmbiguouslyHuman: Their origin is not explained, except for the fact that it was something to do with nano-machines. The fact that they see the Gantz's hunter as enemies indicates that these machines may have alien origin.
* TheAnticipator: Downplayed. They have technology which allow them to see the Gantz's hunters even when they are invisible, it doesn't change the fact they are caught by surprise a few times.
* DaywalkingVampire: It's not the sunlight that is lethal to them, so they have some appearences during daytime.
* LeftHanging: Not much about them is explained, even through they are the antagonists of an arc.
* OurVampiresAreDifferent: They gain vampirism through an infection with nano-machines which creates a strange sing in their backs, sunlight doesn't affect them but artificial light does and there's no mention of they needing to drink blood to survive, although some vampires are shown found of [[IAmAHumanitarian cannibalism]].
* SharpDressedMan: All of them wear suits.
* TreasureChestCavity: They can store pistols and even ''katanas'' in a hole in the palm of their hands.
* VillainDecay: They stop being a treat after the Nurarihyon Mission and are almost completely forgetten during the Katastrophe arc. Justified considering that both Izumi and Kei Kurono killed a lot of them and Host Samurai and Kill Bill are probably the last of their kind.

!Host Samurai/Hikawa

* AuthorityEqualsAsskicking: 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.
* BadassInANiceSuit: He's practically invincible on the battlefield. And, a well dressed one. He wears a black suit and tie.
* CombatPragmatist: He has no problem with fighting dirty if it means winning a fight.
* EmbarrassingNickname: "Host Samurai" is how Gantz refers to him, which "Kill Bill" finds amusing.
* EvilIsPetty: 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, [[EvenEvilHasStandards he loses interest in wiping them out.]]
* HeroKiller: [[spoiler: Kills Izumi, the series definitive AntiHero, and Kei, TheHero. Kei got better, and also a clone.]]
%%* {{Jerkass}}
* KatanasAreJustBetter: His main weapon, it's also surprisingly sharp. [[spoiler:He beheads Kei with it.]]
* LackOfEmpathy: Though how much he lacks is debatable.
* LastOfHisKind: Seems he and Kill Bill are the only vampires left alive after their massive battles with Izumi and Kurono. In Tokyo, at least.
* LeanAndMean: He's quite thin, but very strong.
* LightningBruiser: He hits hard, moves quickly and dodges most attacks.
* MasterSwordsman: Possibly THE Master Swordsman.
* NobleDemon: He displays some sense of honor regarding his comerades. He also cares for Chiaki far more than he lets on.
* OurVampiresAreDifferent
* PetTheDog: When she is mortally wounded, Host Samurai defends "Kill Bill" and carries her on his back to safety, despite claiming to feel nothing for her.
%%* ProfessionalKiller
* RecruitingTheCriminal: Gantz recruits him and Chiaki after they enter his room.
* RuleOfCool: Seems to be what he lives by.
* SeinfeldianConversation: Often gets into these with his vampire comrades on their way to cause some trouble.
* SmokingIsCool: Rarely seen without a cigarette between his lips.
%%* SmugSnake
* TheStoic: Not particularly emotive.
* WhatHappenedToTheMouse: After the Osaka arc, they vanish from the story completely. Gantz doesn't even use them in the final battle against the giants.
* WhiteHairBlackHeart: White-haired evil guy.
* WorthyOpponent: Izumi, Kurono, and Kato. But Izumi especially.
* YouHaveFailedMe: [[spoiler: Kills Akira when he interferes with his plan to assassinate Kurono.]]

!Kill Bill/Chiaki

* AnArmAndALeg: Gets her sword arm sliced off during the Osaka mission. She survives and gets it back.
%%* DarkActionGirl
* EmbarrassingNickname: Either because she is a female wielding a katana or because she vaguely resembles Go-Go Yubari from the movie. Or both.
%%* EmotionlessGirl: Supposedly.
%%* KatanasAreJustBetter
* LastOfHerKind: Along with Hikawa.
%%* OurVampiresAreDifferent
* OutOfCharacterMoment: Hikawa is astonished to hear her giggle at the nickname Kei gave to him.
* NotSoStoic: 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.
* RecruitingTheCriminal: Gantz recruits her and Hikawa after they enter his room.
* StartOfDarkness: As a human, she 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.
%%* UnresolvedSexualTension: With Host Samurai.

!Akira Kurono
Kei's younger brother.
%%* TheAce
* AloofBigBrother: Thinks of Kei as this, despite the fact that he is the younger brother and far more aloof.
* AnnoyingYoungerSibling: Averted. Akira is conventionally successful in life as opposed to his older brother. Kei finds this fact annoying in its own way at times.
* BadassLongcoat: Before and after he becomes a vampire.
* BigLittleBrother: 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.
%%* {{Bishonen}}
* BrokenAce: When he discovers he is a vampire.
%%* DroppedABridgeOnHim
%%* HeroicSacrifice
%%* JerkWithAHeartOfGold
%%* {{Jerkass}}
%%* KilledOffForReal
%%* OurVampiresAreDifferent
* RedemptionEqualsDeath: [[spoiler: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.]]
* SmugSnake: Makes sense when he turns out to be a vampire as well. Even when he [[spoiler: warns his brother of his impending death]] Akira appears only vaguely interested.
%%* WalkingSpoiler
* WhatYouAreInTheDark: [[spoiler:Cares more about the safety of his estranged older brother than his cool new vampire friends.]]

''Others''

* [[Characters/GantzTokyoTeam Tokyo Team]]

!Tsuneo Nikaido, "The Nerd"

* NotSoDifferent: Falls in love with Kaze when she realizes they are this.

* NotSoDifferent: They are an alien, futuristic version of earthly humans.

* SophisticatedAsHell: Able to speak like this, which somewhat emphasizes their NotSoDifferent nature.
