History Main / AdaptiveAbility

** In ''Anime/DragonBallSuperBroly'', Broly is a mutant with a more advanced version of the Saiyan adaptability. He can make himself become more powerful ''during battle'' if he is being overwhelmed by his current opponent, though there is a limit on how powerful he can become this way.

* The enemy in the 2001 film ''Film/{{Evolution}}'' and its AnimatedAdaptation, ''WesternAnimation/{{Alienators|EvolutionContinues}}''.

* In Creator/GregEgan's ''Teranesia'', an evolving organism is apparently able to anticipate future challenges and develop appropriately.

* This trope is played for tragedy and to kill all remaining hope in Creator/JackWilliamson's sci-fi novella ''With Folded Hands...''. A man creates a perfect race of robots to cater to humanity and stop them from killing each other after his home planet was wiped out by civil war. It works too well and the robots begin stripping humanity of its freedom, planet by planet. A man uses rhodomagnetics, the force discovered by the creator and what allows the robots their highly advanced functions, to slip under their radar and attempts to assassinate the creator for dooming mankind. He's stopped, and the creator [[MyGodWhatHaveIDone only then realizes what the robots are doing]]. He jumps from colony to colony, staying ahead of his creation while attempting to create a weapon that will destroy his lifeless homeworld, where the central network is located. He finishes and fires the weapon, only for it to fail. Robots arrive at his residence and inform him that after the assassin, they engineered a way to detect and neutralize rhodomagnetics applied against them, effectively shielding the planet from the weapon. [[DownerEnding This dashes mankind's only hope to free itself from the robots.]]

ElementalRockPaperScissors means that the type it changes to is randomly chosen from the types that resist the last attack.

* Cubia from the first four ''[[Franchise/DotHack .hack//]]'' [=PS2=] games.

** The Tetramorph in ''VideoGame/FinalFantasyX''.
** At least one monster in every other ''Franchise/FinalFantasy'' game as well.
** ''VideoGame/BreathOfFireIII'' has a lot of these as well.
** The Golem in ''VideoGame/ChronoTrigger'' not only defends against the attack type used on it, but begins attacking using that type. This trait makes it very dangerous to the unprepared, and also makes it one of the easiest bosses to beat. With the right equipment and the right attacks, it's very easy to force the Golem to use attacks that are very inefficient against you. In a NewGamePlus, it's stupidly easy to force Golem to use attacks that ''heal'' you. Alternatively, if you have a full range of elemental attacks, the Golem can simply be forced into an endless pattern of elemental charging so long as you never use the same element in succession (assuming you can keep up with the MP cost).
* ''Franchise/{{Pokemon}}'' has two: the Porygon series and Kecleon.
** More specifically, [=Porygon2=]'s [=Conversion2=] move and Kecleon's Color Change ability. [=Conversion2=] is rather more limited, since the nature of Pokémon's ElementalRockPaperScissors means that the type it changes to is randomly chosen from the types that resist the last attack. Color Change is a more typical example.
** Ironically, since Ghost and Dragon-types are weak against themselves, using such a move on Kecleon actually makes it weaker to these attacks then it was before (It starts off respectively immune and neutral to them). Oops.
** Variations of the glitch [[GlitchEntity MissingNo.]] had no [[ElementalRockPaperScissors type]] themselves, and therefore took the type of the last Pokemon loaded.
** There's also an ability called Adaptability, but it only powers up move of the same type (more than usual).

** Sometimes invoked by players in the more random battle facilities in the series - Battle Tower, Battle Frontier, Battle Subway and Battle Maison - as part of the AI. Jossed by RNG-researching hackers who assert that opponents' sets do not take player Pokémon into account. Some players go well beyond streaks of 50, 100 or 200 victories to attain 1,000 or more wins in a row.

** Mayuri Kurotsuchi reveals in the Vandenreich arc that he modified his Bankai to give it this ability. After gathering information on an enemy, it "gives birth" to a creature most suited to fighting it.

** Lots of [[CapeBusters anti-super]] robots: later models of the mutant-hunting Sentinels (especially in the BadFuture of ''ComicBook/DaysOfFuturePast''), the Fury (from ComicBook/CaptainBritain's adventures), and the Shiva series.

** There is a robot appropriately called the Super-Adaptoid who does this by way of PowerCopying. In a ''ComicBook/FantasticFour'' comic, it's defeated by Ben Grimm a.k.a. the Thing, who is his normal human self at the time, but wearing a [[PoweredArmor suit]] that still gives him SuperStrength. Ben Grimm tricks the Adaptoid into copying his normal human self, then uses the suit's power to punch the Adaptoid out in one blow.

* Taken to an annoying degree with Naraku from ''Manga/InuYasha''. He rarely shows up, preferring to attack through subordinates, but when he does, he's always too powerful to take down with whatever attack was effective against him last time. One has to wonder why Sango and Miroku even bothered to come along with Inuyasha, as their attacks eventually became utterly useless against Naraku and they were pointlessly risking their lives.
* Byakuran in ''Manga/Reborn2004'' used this to an extend. He just didn't wait until someone used a certain tactic against him, he simply communicated with himself in alternate dimensions and linked their minds together to make himself crazy prepared for anything.

* In ''Webcomic/OnePunchMan'', Garou has the ability to heal and grow stronger every time he is defeated. By fighting [[OneHitKill Saitama]], he eventually becomes a nigh PhysicalGod. [[spoiler:Spoofed when Saitama continues to crush him, and his body decides he can't evolve any further, so he starts ''devolving'' with each attack until he returns to ordinary human levels.]]

* [[ComicBook/TheDeathOfSuperman Doomsday]] and (in UsefulNotes/{{the Silver Age|OfComicBooks}}) the Calculator and the Shaggy Man from Franchise/TheDCU. Doomsday is a notable example because his Adaptive Ability allows him to literally [[ResurrectiveImmortality come back from the dead]] immune to whatever killed him in the first place on top of his HealingFactor. It says something when Franchise/TheDCU heroes, after exhausting just about every option available to hurt/kill him, eventually had to send him to [[AfterTheEnd the end of time]] just to stop his rampage. In some stories, Doomsday becomes able to adapt offensive abilities to counter his opponents. For example, when fighting ComicBook/MartianManhunter, he becomes able to hit intangible beings and breathe fire as fire is a Martian's weakness. When Superman tries fighting him at a distance, he becomes able to fire his spikes like harpoons.
* Lots of anti-super robots in the Franchise/MarvelUniverse: later models of the mutant-hunting Sentinels (especially in the BadFuture of ''ComicBook/DaysOfFuturePast'', the Fury (from ComicBook/CaptainBritain's adventures), and the Shiva series.
* ''ComicBook/XMen'':
** The [[MeaningfulName appropriately-named]] Darwin has this as his mutant power -- he will immediately mutate whatever he needs to survive. Immerse him in water and he'll grow gills, burn him and he becomes fireproof, poison him and his body chemistry shifts to neutralize it, etc. It's really too bad that it only happens as an unconscious survival mechanism; with control over that power he'd be damn near omnipotent. It should be noted that his powers don't always give him the ability needed to ''win'' a fight, only to survive. When faced with [[ComicBook/TheIncredibleHulk the Hulk]], he gained the ability to [[ScrewThisImOuttaHere teleport several states away]].
*** An ''ComicBook/XFactor2006'' tie-in to ''ComicBook/SecretInvasion'' had a Skrull describe his race's VoluntaryShapeshifting as an adaptive ability similar to Darwin's.
** Random, another Marvel mutant, whose other power was [[ArmCannon turning his hands into guns]].
** Another X-Men mutant, Lifeguard, gets whatever power is needed to save ''someone else'' and [[ExactWords only “someone else”]]. The power does nothing to help if Lifeguard’s own life is the one in danger.
* There was a robot called appropriately the Super Adaptoid that did this. In one comic, it was defeated by [[ComicBook/FantasticFour Ben Grimm]] who was his normal human self at the time, but wearing a [[PoweredArmor suit]] that still gave him SuperStrength. Ben Grimm tricked the Adaptoid into copying his normal human self, then used the suit's power to punch the Adaptoid out in one blow.
** An early X-Men comic during the Mimic's brief tenure as a hero pitted him against the Super Adaptoid, that had already perfected the abilities of ComicBook/TheAvengers. After beating everyone else, including Professor Xavier, the Adaptoid fought the Mimic to a standstill until the Mimic threw the match and psychically convinced the Super Adaptoid to copy his powers. The Mimic's own power was to copy other people's powers, just like the Super-Adaptoid. The attempt to copy that power exceeded the Super-Adaptoid's capacity to duplicate. The feedback also temporarily shut down the Mimic's powers.
* Lobo has this, as a side-effect of his HealingFactor. As with most of his powers, how effective or what it works ''on'' varies wildly between stories and writers. One notable problem arose when a magic spell de-aged him, and also resulted in him become immune to that kind of magic. Unfortunately, the traditional ''cure'' for his condition was from the same type of magic... And Marvel's even-further-over-the-top Lobo parody [[http://www.marvunapp.com/Appendix2/lunatikmerc.htm Lunatik]] has been adapting for six hundred million years, having started as a microbe and eventually eating all life on his homeworld.
* ComicBook/UltimateMarvel:
** This version of ComicBook/TheIncredibleHulk has this to a degree-- he has adapted to environments as extreme as the (simulated) surface of [[DeathWorld Venus]]. This is also the reason why his condition can't be cured -- his body adapts to whatever agent is used to prevent the change. Mainstream Hulk has this too, but to a lesser degree and with less consistency since it's one of his lesser known/used/liked powers. He's been shown adapting the ability to breathe under water and survive the vacuum of space for extended periods.
** ComicBook/{{Wolverine}} in this universe is implied to be the same; in addition to regenerating damaged tissue, his HealingFactor can modify his physiology to compensate for life-threatening injuries. [[spoiler: For example, decapitating him resulted in him developing the ability to directly oxygenate the blood for his brain through his skin. When his severed head was put in a total vacuum, he went into stasis until brought out.]] Ultimate Nick Fury theorizes that Wolverine's mutant power is less "HealingFactor" and more "survive anything". [[spoiler: Well, that worked until Magneto killed him by simultaneously destroying every cell in his body.]]
* Marvel's alien Kree were stuck in an evolutionary dead end, unable to adapt or mutate; so after trying a number of less-than-ideal solutions ([[NoBiochemicalBarriers breeding hybrids with other species]] led to [[AllOfTheOtherReindeer social stratification and prejudice]], setting off a mutagenic bomb led to-- well, a huge frikkin' ''bomb'' that killed half their population and left most of the rest sick and dying) they eventually turned themselves into the Ruul, who can self-adapt to any condition. Later writers seem to have [[RetCon undone most of this]] for no apparent reason.
* One of ComicBook/SpiderWoman Jessica Drew's original powers was that she became immune to any poison after being affected by it once.
* ComicBook/LegionOfSuperHeroes member [[spoiler:and eventual traitor]] Nemesis Kid had the power to gain whatever abilities were needed to defeat any single opponent. [[spoiler:This backfired when he faced Projectra, after murdering her husband ComicBook/KarateKid. His powers gave him the ability to see through her illusions, but when he tried to gloat over her helplessness, she snapped his neck with her bare hands.]]
* Whenever DC's ComicBook/ResurrectionMan is killed by something, he is reborn immune to the way he died. In fact, when he was killed by extreme pain, [[GenderBender he came back as a woman]], because women are [[ScienceMarchesOn supposedly]] more resistant to pain.
* The short-lived villain Freak from [[Franchise/SpiderMan Spider-Man's]] ''ComicBook/BrandNewDay'' storyline became horribly deformed after an accidental chemical bath, but as a result was able to form a cocoon around himself when he died and regenerate with an adaptation against whatever killed him. Such deaths included being set on fire (resulting in a leathery hide), getting shot (armour plating) and strangulation (thicker musculature, particularly around the neck), but he was always just as hideous as before, and all he did with his powers was try to find more drugs to snort up.
* The original run of the ComicBook/NewWarriors had a character with this ability, Helix. He would grow spikes, blades, armor plates, whatever he needed against whatever was being used against him, but the adaptations would quickly fade if he wasn't being attacked. He was initially an antagonist, then was found to only be afraid and lashing out, and started staying with the team. However, he only lasted a few issues before leaving, probably because he would almost inevitably win any fight he got into, making the Warriors ''too'' strong.

[[folder:Films — Live-Action]]

* In ''Literature/LastAndFirstMen'', the Martians do this while fighting the Second Men. [[SciFiWritersHaveNoSenseOfScale Over the course of several thousand years, naturally]]. The shorter timescale is partly down to the Martians' very unusual biology and partly due to the fact that [[ScienceMarchesOn genetics was very poorly understood when the novel was written.]] The structure of DNA wouldn't be identified for another quarter century, for example.

* This trope is played for tragedy and to kill all remaining hope in the sci-fi novella ''With Folded Hands...''. A man creates a perfect race of robots to cater to humanity and stop them from killing each other after his home planet was wiped out by civil war. It works too well and the robots begin stripping humanity of its freedom, planet by planet. A man uses rhodomagnetics, the force discovered by the creator and what allows the robots their highly advanced functions, to slip under their radar and attempts to assassinate the creator for dooming mankind. He's stopped, and the creator [[MyGodWhatHaveIDone only then realizes what the robots are doing]]. He jumps from colony to colony, staying ahead of his creation while attempting to create a weapon that will destroy his lifeless homeworld, where the central network is located. He finishes and fires the weapon, only for it to fail. Robots arrive at his residence and inform him that after the assassin, they engineered a way to detect and neutralize rhodomagnetics applied against them, effectively shielding the planet from the weapon. [[DownerEnding This dashes mankind's only hope to free itself from the robots.]]

* In ''VideoGame/{{Nethack}}'', you. If you manage to kill a red dragon, eat his corpse, and you're immune to fire. The next red dragon's fire breath might damage your equipment, but will not do much damage to you. Same goes for several immunities.
* This is pretty much the point of the Zerg in ''VideoGame/StarCraft''. Notably, their upgrade building is called the "Evolution Chamber," in which the Overmind pits hundreds of zerg warriors against each other and only keeps the strong, and is also the fluff explanation for the origin of Banelings.
** In the campaign of ''VideoGame/StarcraftIIHeartOfTheSwarm'' approximately half the evolution missions involve zerg exposed to various environmental hazards (acid pools, lava, experimental nukes...) in order to grant them new abilities. In the other half the zerg absorb DNA from creatures they [[CannibalismSuperpower consume]].

* In ''Videogame/{{Spore}}'' you edit your creature throughout the cell and creature stages to give them the highest chance of survival.

* This trope is the true source of VideoGame/MegaManX's "Limitless Potential"; he was revolutionary in robotics as he had the ability to learn and grow in strength when [[VideoGame/MegaManClassic previous robots]] had their minds and power levels pre-determined by their creators. [[BigBad Sigma]] takes interest in his potential, and decides to instigate a reploid revolution in order to [[EvilutionaryBiologist evolve reploids to their fullest potential]].

* Syndrome's Omnidroid in ''WesternAnimation/TheIncredibles'' is a much more mundane version of this, insomuch as anything involving a giant robot can be mundane. The Omnidroid's A.I. is programmed to analyze and understand anything used against it, and then adapt its tactics accordingly. The Omnidroid was tested against supers, and whenever a version was destroyed, [[XanatosGambit Syndrome just built a new version based on that data and tested it against the same super]] (invariably defeating them). Throw rocks at it? It'll throw boulders back. Toss it in lava? It's {{Nigh Invulnerab|ility}}le and then will bathe its claws in lava to turn them red-hot. Outspeed, outmaneuver, or outthink it? The next version is faster, more agile, and smarter. [[spoiler:Control it using a remote? It will realize what's going on and attack the remote, removing it from your access. [[GoneHorriblyRight Syndrome finds this out to his own detriment when he attempts to stage a fight with the final version]].]]

* In the ''TabletopGame/MutantsAndMasterminds'' fanfic ''Fanfic/HowAStreetThugKilledAGod'', one of the {{Nominal Hero}}es the main character fights is Adept, who can change his body to gain new physical traits, automatically going for the simplest solution to the problem at hand. [[spoiler:It gets turned against him when he falls into a trap that causes him excrutiating pain via psychic damage. He tries to adapt an immunity to psychic damage, and the GM asks him if he is ''[[PressXToDie absolutely sure]]'' he wants to do that. He says yes, and his power grants him the desired immunity by lobotomizing him into a drooling vegetable. Since he now lacks the brain function to tell his body to change back, he's stuck that way permanently.]]

* [[Comicbook/TheDeathOfSuperman Doomsday]] and (in UsefulNotes/{{the Silver Age|OfComicBooks}}) the Calculator and the Shaggy Man from Franchise/TheDCU. Doomsday is a notable example because his Adaptive Ability allows him to literally [[ResurrectiveImmortality come back from the dead]] immune to whatever killed him in the first place on top of his HealingFactor. It says something when Franchise/TheDCU heroes, after exhausting just about every option available to hurt/kill him, eventually had to send him to [[AfterTheEnd the end of time]] just to stop his rampage.

For example, when fighting ComicBook/MartianManhunter, he becomes able to hit intangible beings and breathe fire as fire is a Martian's weakness. When Superman tries fighting him at a distance, he becomes able to fire his spikes like harpoons.
* Lots of anti-super robots in the Franchise/MarvelUniverse: later models of the mutant-hunting Sentinels (especially in the BadFuture of ''Comicbook/DaysOfFuturePast'', the Fury (from ComicBook/CaptainBritain's adventures), and the Shiva series.
* ''Comicbook/XMen'':

** This version of Comicbook/TheIncredibleHulk has this to a degree-- he has adapted to environments as extreme as the (simulated) surface of [[DeathWorld Venus]].

* One of Comicbook/SpiderWoman Jessica Drew's original powers was that she became immune to any poison after being affected by it once.

* ''Comicbook/{{Spawn}}'''s living symbiotic costume had this ability. After getting whupped by some angels, Spawn retreats to lick his wounds. His costume regenerates from tatters into a new form with bigger spikes and gauntlets, and the next time he meets the angels the fight goes more his way. It had the unfortunate side effect of making the suit more powerful until it almost ate him, though.

* In the AlternateUniverse ''Literature/{{Worm}}'' fanfic ''FanFic/{{Intrepid}}'', Anne's power set basically allows her to fully understand someone's power with a touch and then use a power to counter it. Such as using a cold wave to get rid of Lung's pyrokinesis and a teleportation power to get rid of Lung far enough to where he'll cool down.

* Parodied by the Haggunenons in ''Radio/TheHitchhikersGuideToTheGalaxy'', who would shapeshift into seemingly random "adaptations" because they have "the most impatient chromosomes in the Galaxy".

* In ''Videogame/{{Nethack}}'', you. If you manage to kill a red dragon, eat his corpse, and you're immune to fire. The next red dragon's fire breath might damage your equipment, but will not do much damage to you. Same goes for several immunities.

* ''Videogame/{{Warframe}}'':

The Adaptive Ability is a power to [[EvolutionPowerUp adapt]] to any power used against it. Hit this enemy with a fireball? Next time it's immune to fire. Same with any ElementalRockPaperScissors attack. Cut it, it now has armor. Psychic powers, it now has mindshields. A long fall might [[WingPull give it wings]]. Try to TeleFrag it? Now warping into where it is will redistribute ''[[RussianReversal you]]''.

* Yggdrasil in ''LightNovel/UndefeatedBahamutChronicle'' can not only gain resistance to attacks used against it, but also grows stronger and faster the more it's attacked. This does have limits, as it will eventually run out of life force if attacked enough, but in its first appearance it has eaten and absorbed the life force of hundreds of other Abyss

* ''LightNovel/FateApocrypha'': Berserker of Red's Noble Phantasm, Crying Warmonger: Howl of the Wounded Beast, makes him [[FeedItWithFire become stronger every time he takes damage]]. [[AllThereInTheManual Supplimental material]] states that if he was summoned as a Saber, Crying Warmonger would also make him immune to or even reflect attacks back after getting hit with them once.

** Since Cell was partially cloned from Saiyan cells, he has this ability as well. In fact, the combined abilities to Self-Destruct + Survive so long as one cell remains + come back stronger from a near-death experience is quite dangerous.

* In ''LightNovel/ACertainMagicalIndex'', Fraulein Kreutune has a brain that rapidly absorbs information from her surrounding environment, causing her body to change in response.

* An episode of ''Series/TheOuterLimits1995'', "The New Breed", had a man infested with {{Nanomachines}} programmed to heal and protect his body, which they did [[LiteralGenie mindlessly and efficiently]]-- he nearly drowns and grows gills, he gets beaten up and grows extra layers of bone, and his skin develops poison glands like a jellyfish, so ''no one can touch him''. They also, for some reason, decide that having a limited field of view is a flaw, so they grow an extra pair of eyes on the back of his head.

* Reidak from the ''Toys/{{Bionicle}}'' series. Specifically, any power used to defeat him will be ineffective for the next go around (i.e. he gets knocked down by a giant fist of earth and won't feel a thing if it happens again, even if the fist of earth is twice as big). However, the power seems to have a "reset" function after a battle, and unlike [[Creator/DCComics Doomsday]], he won't be coming back from something that actually ''kills'' him.

* Many of the enemies in ''Manga/SaintSeiya'' are fond of declaring that they could not be hit by a technique once they have already seen it. Given our heroes' reliance on StockFootage {{finishing move}}s, this seems like it would be a downright crippling handicap for them ...
* Shishioh from ''Manga/RurouniKenshin'' has a non-supernatural version of this. One of his skills is that he just innately knows how to counter any attack he sees once.

** In the campaign of ''VideoGame/StarcraftIIHeartOfTheSwarm'' approximately half the evolution missions involve zerg exposed to various environmental hazards (acid pools, lava, [[NuclearNasty experimental nukes]]...) in order to grant them new abilities. In the other half the zerg absorb DNA from creatures they [[CannibalismSuperpower consume]].

* In the ''TabletopGame/MutantsAndMasterminds'' fanfic ''Fanfic/HowAStreetThugKilledAGod'', one of the {{Nominal Hero}}es the main character fights is Adept, who can change his body to gain new physical traits, taking the shortest path to his goal. [[spoiler:Gets deconstructed when Adept falls into a trap that causes him incapacitating pain, and his power renders him a vegetable as part of him becoming immune to pain.]]

* In ''Literature/{{Dune}}'', the Bene Gesserit (and those trained in their methods like Paul Atreides) have the ability to change their internal chemistry. This makes them immune to poisoning, as they will simply change the composition of the poison to something that is not lethal.

* ''Wiki/TaerelSetting'': The kin'toni "adapt to the land around them" with mutations, such as the blind, albino Minemi Kin'toni Clan (adapted to caves), the albino Phuis Kin'toni Clan (another cave clan), and the deep sea water-adapted Tiess Kin'toni Clan, who have gills and are (again) blind.

** And to make matters worse, they're [[AbsoluteXenophobe obsessively xenophobic]], want to TakeOverTheWorld, aren't fussed about whether they do it by [[AssimilationPlot assimilating us]], [[KillEmAll slaughtering us]], or [[ToServeMan sticking us in wax to digest to death]], and are [[HiveMind controlled]] by a Queen who's the [[UncannyValley stuff of]] nightmares [[PsychopathicManChild all by herself]].

* ''Wiki/SCPFoundation''

* In ''VideoGame/{{XCOM 2}}: War of the Chosen'', the eponymous villains gain new abilities in response to what XCOM uses against them.

* ''Webcomic/GrrlPower'' has minor villain "[[AtrociousAlias For Whom The Death Tolls]]", who dresses like a comic-book villain (skull mask, cowl, cape, and garish coloring) in part because [[https://grrlpowercomic.com/archives/comic/grrl-power-246/ this is his power set]]. Any attack made against him grants him a power to counter that attack perfectly - sapping [[EnergyAbsorption Anvil's]] strength, absorbing [[ShockAndAwe Jiggawatt]] entirely, pushing her electric-form ''through'' [[MightyGlacier Stalwart]], etc. However, this has the limitation in that he can only manifest counters to a certain number of attacks at once, and only when he's attacked - too many powers to counter will result in at least one blow making it through, and not attacking him at all renders his power useless.
-->'''Sydney''': Nemesis made it look like he had ''every'' power, but he only had ''any'' power. [[https://grrlpowercomic.com/archives/comic/grrl-power-246/ Big difference]].

* In ''Literature/{{Twig}}'', the protagonist, Sylvester, is regularly injected with a cocktail of venoms and toxins which have this effect on his brain by boosting his brain plasticity, effectively enabling him to rapidly increase his skills in an area he focuses on at the cost of long-term memory loss and deterioration in areas he doesn't focus on. He uses it to adapt his skillset to fill the role he needs to fill in his team, most frequently as TheSocialExpert.
In Wiki/{{Taerel Setting}}, the vampires "kin'toni" "adapt to the land around them" with mutations, such as the blind, albino Minemi Kin'toni Clan (adapted to caves) and the albino Phuis Kin'toni Clan (another cave clan) and the deep sea water-adapted Tiess Kin'toni Clan who have gills and are again, blind.

** The [[MeaningfulName appropriately-named]] Darwin has this as his mutant power -- he will immediately mutate whatever he needs to survive. Immerse him in water and he'll grow gills, burn him and he becomes fireproof, poison him and his body chemistry shifts to neutralize it, etc. It's really too bad that it only happens as an unconscious survival mechanism; with control over that power he'd be damn near omnipotent. It should be noted that his powers don't always give him the ability needed to ''win'' a fight, only to survive.
