4	When a MetamorphosisMonster has multiple defined evolutionary lines.
5
6	It can have a "common" line, where a small beast grows into a larger version of itself and the conditions for what it turns into can be more easily met. Then there are the "rare" or "bonus" evolutionary lines where it becomes a different monster entirely, depending on what it eats or where it lives or if you've gathered the necessary equipment it needs to undergo this special alternate form.
7
8	[[MonsSeries Games where you breed, train, or create monsters]] will have such beasts available to add challenge and busy-work for the player. You [[GottaCatchThemAll want to catch them all]]? Well then you need TwentyBearAsses if you want the shiny-version!
9
10	When the monsters are a product of the villain, the existence of these diverging forms not only add variety to keep TheHero from growing complacent with the GoddamnedBats they have to face, but it raises the stakes by revealing that the person making all of these monsters isn't a one-trick pony and their tactics are evolving just like their beasties.
11
12	And that's not even going into the FanficFuel and FanArt that results from how these monsters could potentially turn out when they control the recipe.

21	* ''Franchise/{{Digimon}}'': While most Digimon have set evolutionary lines, there are times when a Digimon will digivolve into an alternate form. These alternate forms can be achieved using regular digivolution or via an alternate form of digivolving.
22	** "Dark Digivolution" happens when a Digimon is coerced into digivolving while under intense negative emotions (either their own or their human partner's), resulting in the Digimon digivolving into a Virus-type form instead of their usual digivolved form.
23	*** In ''Anime/DigimonAdventure'', Greymon digivolves into [=SkullGreymon=] after Tai tries forcing Agumon into digivolving on command (first by overfeeding him, then by deliberately putting himself in danger). He then later helps Agumon digivolve into his proper Ultimate form, [=MetalGreymon=]. In ''Anime/DigimonAdventure02'', the Digimon Emperor manages to capture Agumon and tries to forcefully digivolve him to [=MetalGreymon=] using his Dark Digivice, but he becomes [=SkullGreymon=] instead. He then later manages to force Agumon to digivolve into [=MetalGreymon's Virus Mode=] while under the effects of a perfected Dark Spiral.
24	*** ''Anime/DigimonTamers'': When Takato is overcome with grief and rage after Beelzemon kills Leomon, Guilmon utilizes Takato's negative energy to warp digivolve into Megidramon, a DraconicAbomination whose very existence destabilizes the Digital World. After reconciling with Guilmon and his own grief, Takato then helps him digivolve to his proper Mega form, Gallantmon.
25	** "Armor Digivolution" is when a Digimon digivolves with the power of a Digi-Egg. This was considered a lost form of digivolution that Digimon used in the past before they eventually learned how to do it without the need of armor. In ''Anime/DigimonAdventure02'', the Digimon Emperor's Dark Spires block Digimons' ability to Digivolve normally; Veemon, Armadillomon, Hawkmon, Patamon, and Gatomon gain the ability to Armor-Digivolve when their Digidestined partners discover the Digi-eggs. Over the course of the season, the Digidestined would end up finding multiple Digi-Eggs that allowed their Digimon partners to achieve multiple Armor forms. The only exceptions are, Patamon and Gatomon, who both only gained one Armor form and SixthRanger, Wormmon, who never gained any Armor forms. Veemon becomes Flamedramon and Raidramon, Hawkmon becomes Halsemon and Shurimon, and Armadillomon becomes Digmon and Submarimon. Veemon is also the only Digimon that was able to utilize the unique Golden Digi-Egg to achieve a third Armor form, Magnamon.
26	** Keep in mind the above applies to the various anime and manga series. The Virtual Pets, video games and trading card games ''are not remotely limited to these.'' The evolution chart for Botamon in ''VideoGame/DigimonStoryCyberSleuth''? It looks like ''[[https://i.imgur.com/wOgpg6g.jpg this.]]'' Notice how Agumon has ''five'' evolution routes, and both versions of Greymon each have ''three'' different possible Digimon they could evolve from. The Virtual Pets can be even more complex. And then [[BeyondTheImpossible there's the TCGs...]] [[https://wikimon.net/Agumon The Wikimon page for Agumon]] lists all the known possible evolutions across various Digimon media, and they number in the ''dozens''. ''Thankfully,'' outside of the card games, most Digimon rarely have more than two to five standard evolution options, most of the time an evolution can be accessed by multiple Digimon species (providing you with a lot of flexibility), and in some games like the ''Digimon Story'' sub-series de-evolution is easily accessible (and actively encouraged in ''Digimon Story'', as de-evolution increases a specific stat that allows for higher levels and often unlock new evolutions), making it easier to acquire every single one.

30	[[folder:Fan Works]]
31	* Basilisks in ''Fanfic/TheAngelOfTheOwlHouse'' are unique in many ways, one of which being that they can undergo a physical change that reflects on what type of magic they typically eat. Subject Zero (the basilisk that attacked Hexside) was a Greater Basilisk, a species that comes about from eating various types of magic throughout its lifetime. Vee winds up becoming a Quetzalcoatl Basilisk after eating enough angelic magic through Luz and Camilla's angelic blessings, allowing her to absorb magic passively through her wings like an angel instead of needing to feed, and even allowing her to cast some basic spells.

34	[[folder:Films -- Live-Action]]
35	* In the ''{{Franchise/Alien}}'' series, the Xenomorphs while in their chestburster stage have the ability to take genetic traits from their hosts and incorporate it into their own biology. While the movies, comic books and video games have mainly shown Xenomorphs born from human hosts, the [[Film/Alien3 third movie]] introduced a Xenomorph born from a canine host while the ''Franchise/AlienVsPredator'' series featured a Xenomorph called the Predalien which shared its host's dreadlocks and mandibles.
36	[[/folder]]

38	[[folder:Literature]]
39	* ''Literature/{{Fragment}}'': The sequel, ''Pandemonium'', reveals that many of [[DeathWorld Hender's Island]]'s organisms are actually different forms of the same species, such as the disk-ants being capable of metamorphosing into several varieties of tree-like {{planimal}}s or the near-microscopic "nano-ants" that crawl over the skin of larger animals as symbionts, and the Hender's rat, which can be induced to transform into the gargantuan spiger by other rats. This, along with the fact they're almost all {{Explosive Breeder}}s, means that just ''one'' Hender's Island organism is needed to turn new land into a self-sustaining ecosystem.
40	* Invoked in ''Literature/SoImASpiderSoWhat''. Being reincarnated as a spider monster, [[Characters/SoImASpiderSoWhatKumoko Kumoko]] discovers that when she reaches a high enough level, she is given options on what kind of different types of spider monsters she can evolve into. She makes various intelligent choices (choosing smaller forms that emphasize speed and resourcefulness so that she can avoid being trapped underground) in the hopes that she will eventually become an [[SpiderPeople Arachne]] to better communicate with humans.

43	[[folder:Live-Action TV]]
44	* ''Series/AlienWorlds2020'': The pentapods are aliens that live on a tidally-locked planet, with one side being perpetually cold and dark, the opposite side being hot and sunlit, and a thin band in-between of temperate perpetual twilight. The pentapods are able to change into forms suited to all three environments depending on where their drifting eggs land, allowing them to dominate the planet. Those on the dark side are woolly and stockily built for conserving heat, those on the light side are spindly and have reflective skin for keeping cool, while the ones in the middle are colourful and have in-between proportions.

47	[[folder:Video Games]]
48	* In ''VideoGame/CassetteBeasts'', several monsters have alternate evolution paths. Some are acquired by having specific stickers equipped to the monster when you remaster it, others involve environmental factors like time of day, and yet others change depending on the player's answer to an abstract question. For example, when you remaster the two [[StarterMon starter monsters]], Candevil and Bansheep, you are asked a mysterious question -- whether you wish to pursue alchemy or metallurgy for Candevil, and whether a restless spirit should be buried or ascended for Bansheep -- which determines its path.
49	* ''VideoGame/ChronoCross'': Pip has up to five possible forms based on the Elements that he uses. Primarily using "dark" Elements (Red, Yellow, or Black) makes him evolve into a devil, and then archdevil form; primarily using "light" Elements (Green, Blue, or White) makes him evolve into an angel, and then archangel form; while switching his Elemental affinity after the first evolution allows Pip to access his Holy Beast form.
50	* ''VideoGame/DoodleWorld:''
51	** Heatza can evolve into either Meltimaw or Gigarlic depending whether it knows the move Fatten Up upon evolution (Gigarlic if it does, Meltimaw if it doesn't).
52	** Seamsquire evolves into either Seamstress or Seamknight depending on gender (Seamstress if female, Seamknight if male).
53	** Flaskit has four separate evolutions depending on the evolutionary item given to it, or if none is given at all (Noxvul if the Strange Catalyst was given, Endovul if the Strange Solution was given, Exovul if the Strange Substance was given, or Vuliable at Level 29.)
54	* In ''VideoGame/FinalFantasyXIV'', all dragon hatchlings have the same basic body shape: four legs, a pair of wings, and a long tail. However, their bodies adapt to their way of living and the environments they grew up in. A dragon with a talent for manipulating wind aether who spends most of their time flying may develop into a wyvern and later an elder wyvern with larger wings fused to their arms to have an easier time soaring among the clouds. By contrast, dragons who spend most of their time on the ground and manipulate earth-aspected aether may lose their wings entirely and become tortoise-like carapace dragons. [[spoiler:Ehll Tou, a dragonling who takes a strong interest in crafting, develops a bipedal form with pronounced and dextrous front limbs to better use crafting tools.]]
55	* ''Franchise/{{Metroid}}'': The eponymous Metroids have a "natural" metamorphosis line introduced in ''VideoGame/MetroidIIReturnOfSamus'', where Metroids left on SR-388 (or a facsimile like the one in ''VideoGame/MetroidFusion'') change from the basic jellyfish-like larval form to more insectoid and later dinosaur-like instars. On different planets, however, they metamorphosize differently. ''VideoGame/SuperMetroid'' shows that the Zebes strain will grow into larger versions of the jellyfish stage rather than change form entirely. The ''VideoGame/MetroidPrimeTrilogy'' also shows how Metroids change in response to consuming Phazon, ranging from the misshapen and long-tentacled Hunter Metroids in ''VideoGame/MetroidPrime'' to the bifurcated and semi-incorporeal Phazon Metroids in ''VideoGame/MetroidPrime3Corruption''.
56	* ''VideoGame/MonsterSanctuary'': Draconov is the only monster in the game with multiple evolutions, known as the Draco family. Each one specializes in a different pair of elements and lives in a different environment.
57	* ''Franchise/{{Pokemon}}'': There are many Pokémon that have different evolved forms that can be achieved when certain conditions are met, whether it involves using a certain Evolution stone, the Pokémon's gender, what time of day it evolves, etc.
58	** Eevee, the "Evolution Pokémon", is the TropeCodifier when it comes to {{Mon}}. Eevee is a Normal-type Pokemon resembling a brown fox that is famous for having a great many different options for what it can evolve into utilizing different methods. Such options include evolution stones ([[MakingASplash Vaporeon]], [[ShockAndAwe Jolteon]], and [[PlayingWithFire Flareon]]), leveling up with high friendship during the day or night ([[PsychicPowers Espeon]] and [[CastingAShadow Umbreon]]), leveling up in a specific location ([[GreenThumb Leafeon]] and [[AnIcePerson Glaceon]]), and leveling up with high friendship while knowing a specific type move ([[OurFairiesAreDifferent Sylveon]]).
59	** Wurmple has two evolutions when it reaches level 7, however, which one it evolves to is dependent on a hidden personality value. It will evolve into either Silcoon or Cascoon, who will then evolve into the butterfly-esque Beautifly and the moth-like Dustox, respectively.
60	** Tyrogue evolves into either Hitmonlee, Hitmonchan, or Hitmontop depending on its Attack and Defense stats at Level 20 (higher attack, higher defense, and equal, respectively).
61	** Slowpoke has two evolutions, one by leveling up and one by trade item. It will evolve into Slowbro once it reaches level 37 or it will evolve into Slowking if traded while holding a King's Rock.
62	** Cosmoem is unique not only for being one of the few Legendary Pokémon that can evolve, but also for being the only Legendary Pokémon with a branching evolution. It's also unique in that it's the only Pokémon whose evolution is dependent on what version of the game it's in. It evolves into Solgaleo in Sun, Ultra Sun, Sword, and Scarlet, while in Moon, Ultra Moon, Shield, and Violet, it evolves into Lunala.
63	** Many Pokémon evolve by being exposed to items, such as evolution stones, or when traded while holding a specific item. Then there are some Pokémon that have multiple branching evolutions depending on which item is given to it and/or what item it has while being traded. Examples include:
64	*** Applin has three item-based evolutions based on what kind of apple its given. It will evolve into Flapple if given a Tart Apple, it will evolve into Appletun if given a Sweet Apple, or it will evolve into Dipplin if given a Syrupy Apple. Dipplin is also unique in being one of the few item evolution Pokémon that can evolve again, as Dipplin evolves into Hydrapple by leveling up while knowing the move Dragon Cheer.
65	*** Poliwhirl has two item-based evolutions. It will evolve into Poliwrath if given a Water Stone or it will evolve into Politoed if traded while holding a King's Rock.
66	*** Clamperl is unique for having two trade evolutions. It will evolve into Huntail if traded while holding a Deep Sea Tooth or it will evolve into Gorebyss if traded while holding a Deep Sea Scale.
67	*** Gloom has two stone-based evolutions. It will evolve into Vileplume if exposed to a Leaf Stone or it will evolve into Bellossom if exposed to a Sun Stone.
68	*** Charcadet has two evolutions based on what kind of armor its given. It will evolve into Armarouge if given Auspicious Armor or it will evolve into Ceruledge if given Malicious Armor.
69	*** Scyther has two item evolutions. It will evolve into Scizor if traded while holding a Metal Coat or it will evolve into Kleavor if given a Black Augurite.
70	** Nincada is unique in that it has a simultaneous evolution into two evolved forms, but with the catch that one of them only appears under specific circumstances when evolving into the other. When Nincada evolves into Ninjask at level 20, its other evolved form, Shedinja, will only appear if there is an empty slot in the player's party and if there is an extra Poké Ball in the player's inventory. If these conditions are not met, then Shedinja will not appear and cannot be obtained, although Nincada will still evolve into Ninjask regardless.
71	** Some Pokémon have final evolutions that are restricted to one gender while still having a regular final evolution available to both sexes. For example, both male and female Kirlia can evolve to Gardevoir, but only male Kirlia can evolve to Gallade. Similarly, only female Snorunt can evolve into Froslass, while both male and female Snorunt are able to evolve into Glalie.
72	*** Burmy is an interesting example in which both genders have an exclusive final evolution that the other cannot evolve to. All female Burmy evolve into Wormadam, while all male Burmy evolve into Mothim. In addition, Wormadam also has a different secondary type depending on the cloak that female Burmy has when she evolves, whereas Mothim always has the same typing regardless of male Burmy's cloak. The plant cloak makes Wormadam Bug/Grass, the Sandy cloak makes her Bug/Ground, and the Trash cloak makes her Bug/Steel.
73	* Chao from ''Franchise/SonicTheHedgehog'' are a race of {{Ridiculously Cute Critter}}s that are capable of changing from their default state (typically called "Normal Chao") and can either turn into "Hero Chao" or "Dark Chao" based on what character care for or mistreats them. They are also capable of taking on the rare "Chaos Chao" form if certain conditions are met.
74	* ''VideoGame/Starcraft'':
75	** In the first game, Mutalisks could permanently metamorphose into Guardians, going from FragileSpeedster flyers with a bouncing attack to a GlassCannon flying siege monster. The expansion added Devourers as an option, anti-air flyers with SplashDamage.
76	** The Zerg-centric ''VideoGame/HeartOfTheSwarm'' gives ''every'' unit a choice of two mutually-exclusive forms (although it's more a choice between which to use for that level), giving each its dedicated mission to test it out in ideal conditions:
77	*** Zerglings now come in Raptor (more damage, can jump cliffs and over enemies) and Swarmling (spawn much faster in threes instead of two).
78	*** Corpser Roaches can gain a SpawnBroodlings attack, while Vile Roach attacks slow enemies.
79	*** Hunter Banelings can jump cliffs and over enemy heads, while Splitter Banelings, well, split into two smaller Banelings on death.
80	*** Hydralisks can turn into Lurkers (a creature that burrows to send lines of underground spikes into enemies) or Impalers (same idea, but trading the line damage for high single-target damage).
81	*** Mutalisks can turn into Brood Lords (similar to Guardians from the first game) or Vipers (anti-air flying SupportUnit that can yoink enemies to themselves).
82	*** Ultralisks come in Torrasque (turns into a coccoon on death that rejuvenates it) or Noxious (constantly spews poison around itself) variants.
83	*** Creeper strain Swarm Hosts can teleport (well, deep-burrow) onto creep anywhere, while the Carrion strain creates flying locusts instead of the ground-based ones.
84	* ''VideoGame/{{Temtem}}'': Tems with multiple evolutions are known as "meta-mimetic".
85	** Tuwai, an {{Expy}} of Eevee, has six evolutions that can be obtained at the shrines on each island.
86	** Male Towly evolve into Owlhe, while females evolve into Barnshe.
87	** Venx with the Parrier trait evolve into Venmet, while ones with Arcane Wrap evolve into Vental.

90	[[folder:Webcomics]]
91	* In ''Webcomic/JustAGoblin'', Nog is given the opportunity to evolve into a more powerful species of goblin after reaching a certain level. He's given the choice between becoming an enormous hobgoblin, a magical winged fay goblin, or the ghost-like onare goblin. He ultimately chooses the latter, gaining the ability to detach and reattach his arms at will, perfect night vision, and strange, dark powers.
92	[[/folder]]
93
94	[[folder:Websites]]
95	* Some adoptable pets in ''Website/ChickenSmoothie'' have branching growths, and some vary wildly in anatomy and appearance. In one instance, a litter of chicken eggs once had a split outcome where some grew into dragons.
96	* As well as the ''Pokémon'' examples listed above, ''Website/PokeFarm'' converts the Nidoran lines into this by [[CompositeCharacter merging them into a single Mon]] that evolves into either Nidorino or Nidorina depending on gender. A few of the site's original Pokémon have branching evolutions as well:
97	** Petripeep evolves into Chirock if male, or Serpitone if female; genderless Petripeep can be evolved into either by giving them a specific evolutionary stone.
98	** Kawotor evolves into either Lutriva or Selutian depending on which evolutionary stone it's holding when it reaches Level 30.
99	** Caprakid evolves into either Saytaries, Taurminos, or Sagidamas depending on its Attack and Speed stats at Level 20.
