Evolution/Video Games

=Appearances=

Digimon evolve after reaching a certain lifespan. Baby I Digimon can only evolve into a single Baby II Digimon, but afterwards, Digimon will have several possibilities for their evolutions. Which Digimon they will evolve into, if any, depends on specific conditions they meet, such as their stats, how many moves they have, how many care mistakes they have, how many attacks they've learned, how many battles they've had, etc.

Beyond the normal evolution lines, some evolutions can be obtained through special means.
 * If a Baby II-level Digimon sleeps in Kunemon's Bed, it'll evolve into Kunemon.
 * If a Digimon poops too much outside of the toilet, they'll evolve into Scumon.
 * If a Child-level Digimon fails to meet any evolution conditions when the evolution time comes, they'll evolve into Numemon.
 * If an Adult-level Digimon is at least 15 days old, has a Discipline below 50%, and is then scolded, it may evolve into Vademon.
 * If the player interacts with the Monzaemon plush in Toy Town with a Numemon as their partner, said Numemon will evolve into Monzaemon. Unlike the previous examples, Numemon can also naturally evolve into Monzaemon.

Evolution is one-way in Digimon World. The only exception is Scumon, who can be returned to its previous form by talking to Great King Scumon in Trash Mountain.

Furthermore, most Adult and Perfect Digimon are associated with a matching evolution item. Using one of these items on a compatible Digimon will automatically evolve it into the item's matching Digimon with no further evolution requirements.

For the most part, evolution is not a mechanic in and of itself. However, there are two related mechanics:


 * Digimon can learn Variable Moves which, according to a Nanimon, temporarily evolve them into the target Digimon long enough to perform one of its attack techniques.
 * Three Digimon&mdash;Numemon, Otamamon and Bakemon&mdash;evolve into, respectively, Scumon, Gekomon and Soulmon when they are traded between players.

Additionally, the main antagonist Millenniumon is the result of a fusion between Mugendramon of the Dark Master and a Chimairamon. In the

In the second phase of each player's turn, the Evolution Phase, players are given a chance to evolve their current Digimon card in play. The standard way of performing an evolution is spend a specified amount of Evolution POW points, which are accumulated in the Evolution Phase by selecting one card per turn to send to the POW Box, to evolve the Digimon card in play into one selected Digimon card of the next Level up. There are many Option Cards that can be played instead to bypass the usual requirements.

Any Digimon card is capable of evolving into any Digimon card that a) is of the next Level up, and b) shares the same Attribute/color.

Evolution cannot usually be undone. The only way of doing so is to use the Option card Devolution, which discards the top card of your Digimon and returns it to its previous stage, with doubled HP.

Digimon can be evolved by talking to the Evolution Operators. A Child Digimon may evolve to Adult Digimon at LV 11, an Adult Digimon may evolve to Perfect Digimon at LV 21, and a Perfect Digimon may evolve to Ultimate Digimon at LV 31. One level after evolving, the Digimon will learn every technique of their level that their current form, as well as the Digimon that were Jogressed into them, can learn. What Digimon will be born from an evolution is decided by both the previous Digimon and their current EP (Evolution Points).

Jogress Evolution is also in the game, and can also be done by talking to the Evolution Operators. Child-level Digimon cannot be Jogressed. Upon Jogress, a new Digimon will be created. The newly-created Digimon will be one evolution level lower than the lowest evolved Digimon that created it (for example, if two Adults are Jogressed, a Child will be born, as well as if an Adult and a Perfect are Jogressed). The newly created Digimon will have a higher max level than its parents, based on their own levels, as well as 1 more EP than the highest EP of both of them. Furthermore, the newly born Digimon will be able to learn every move of its parents once it hits certain levels.

Evolution is completely one-way in Digimon World 2.

Fundamentally, once a Digimon gains enough experience points, it will automatically evolve into the next available Digimon in its evolution line. A Digimon's evolution line is pre-set based on which of the 70 distinct Digitamas, identified by both a name provided by Digitamamon and an unseen number, to which it belongs.

Gaining access to new evolutions revolves around Jogressing Digimon at Digitamamon's Jogress Room. Any two Digimon who are at Child level or higher may be Jogressed together to produce a Digitama, which immediately hatches into a Baby I Digimon. The resulting Digitama is based on which Digitamas the two parents belonged to or, in certain special cases, their Digimon species at the time of Jogressing, and Jogressing certain combinations of Digitamas will yield particular Digitamas.

Digitamas are sorted by a rank system from 1 to 9, and Jogressing will often result in a Digitama of a higher rank than the parents. In addition to having increased stats, higher-ranked Digitamas generally have greater access to more powerful Digimon and/or Digimon of higher Evolution Stages. This also includes better variants of the same evolution lines, which add Digimon of higher Evolution Stages.


 * For example: There are two Digitamas that yield V-mon. The first that they player can encounter is Digitama #1 (rank 2), the "V-mon" Digitama; the furthest that a V-mon of this Digitama line can evolve, assuming it meets all other requirements, is to its Adult form, XV-mon, and the evolution line ends there. The second is Digitama #22 (rank 4), the "Imperialdramon" Digitama&mdash;which is formed by Jogressing an XV-mon from Digitama #1 with a Stingmon from Digitama #2 (rank 2), the "Wormmon" Digitama&mdash;adds, respectively, Paildramon and Imperialdramon as Perfect and Ultimate forms, so a Digimon belonging to the Digitama #22 line, assuming it meets all other requirements, can evolve all the way to Imperialdramon.

Every time that a Jogress is performed, the resulting Digimon will gain Jogress Points (JP). In addition to the EXP requirement, Adult, Perfect and Ultimate Digimon may only be evolved into if the Digimon also meets a minimum JP requirement for each; both EXP and JP requirements get progressively higher for higher-ranked Digitamas.

Additionally, some evolution lines feature two Adult, Perfect and/or Ultimate forms. In these cases, one Digimon of a given level (the "higher" Digimon) can only be evolved into if the Digimon has any Digimental equipped, and otherwise, it will evolve into the other Digimon of that level (the "lower" Digimon). Likewise, in some cases where there is only one Ultimate form in the line, a Digimon cannot evolve into that Ultimate form unless it has a Digimental equipped.

Evolution is one-way and cannot manually be reversed, but once the Digimon reaches the end of its lifespan (i.e. once their lifespan ("Y") stat gets high enough, signified by a cross appearing next to them in menus), it will revert to its Baby I form and lose all EXP and learned techniques, starting its evolution from the very beginning.

Five Digimon species&mdash;V-mon, Hawkmon, Armadimon, Patamon, Tailmon&mdash;may also use Armor Evolution, which works as a special type of attack technique. Having a matching Digimental equipped allows the Digimon to learn the resulting Armor Digimon's attack technique; using this technique in battle will cause it temporarily evolve into that Armor Digimon long enough to perform that attack techniques, before returning to its original form.

In Digimon Adventure 02: D1 Tamers, both natural evolution and Armor Evolution work near-identically to how they did in Digimon Adventure 02: Tag Tamers, save for the following changes.

For natural evolution:
 * There are now a total of 79 Digitamas. Some Digitama evolution lines from Tag Tamers have been altered or moved to a different identifying number.
 * A new rare item, the JogPlus, is introduced. Using it gives the chosen Digimon 5 JP, helping to speed up gaining enough JP to meet evolution requirements. Although it is rare, it can still be infinitely farmed by repeatedly playing through the dungeons in which it can spawn (Plush Tower, Angel Tower, Undead Box, any of the Four Holy Beasts' dungeons).
 * A tenth Digitama rank is added, exclusive to new Digitama evolution lines that yield two bonus Digimon: Archnemon (#21) and Mummymon (#79).
 * In the Jogress Room, Digitamamon now directly tells the player the identifying number of the Digitama of any Digimon in their party.
 * The mechanic of certain Jogresses requiring parents be of particular species within a given Digitama line has been removed entirely. Results are now consistent regardless of parents' current form.
 * A Digimon's lifespan coming to an end may be delayed by equipping a Digimental of Life.

For Armor Evolution:
 * Armor Evolution techniques do not need to be learned by winning a battle like before. Instead, they are made available automatically in the Digimon's sixth technique slot, reserved for techniques provided by the currently equipped Digimental.

Natural evolution works identically to how it works in Digimon World: Digital Card Battle.

Digital Card Arena adds a new mechanic, Armor Evolution, as an alternative to natural evolution. Armor Evolution is available to the six Partner Cards&mdash;V-mon, Hawkmon, Armadimon, Patamon, Tailmon and Wormmon&mdash;but requires that the player obtain the corresponding Digimentals for each Partner Card by progressing through the game. If the player has at least one Digimental for a given Partner Card, then as soon as they play that Partner Card on the field, they are given the option to use the Digimental to evolve the Partner Card into the corresponding Armor Digimon with no further cost. However, Armor Digimon cannot evolve any further, unless they are devolved back to Level III (Child) using certain Option Cards and are re-evolved into Level IV (Adult) or Perfect from there.

NPC Digimon who originate from Digimon Adventure and Digimon Adventure 02 will evolve over the course of the game. Upon evolving, they will have different, stronger decks, and are counted as different characters for wins/losses. The Digimon Adventure 02 partner Digimon specifically have Extra Arenas in which they battle the player using all their evolution stages. Wormmon does not have an Extra Arena, but he can still be fought in all of his stages except Gran Kuwagamon in Dark City's Battle Arena.

&
Playable Digimon can temporarily evolve by touching Culumon, who appears halfway through each match. As long as they are evolved, they are entirely invincible and are able to use much more powerful attacks. Culumon only appears once per battle, thus only one evolution can happen per match.

In the original Digimon Tamers: Battle Spirit, Impmon is unable to evolve, and if he touches Culumon, Culumon is forced to despawn. Ver. 1.5 adds in an evolution for him: Beelzebumon: Blast Mode.

Ten playable Digimon are able to evolve during matches: Agumon, Gabumon, Patamon, Tailmon, V-mon, Wormmon, Guilmon, Renamon, Terriermon, and Impmon. Each of these Digimon has one evolved form, which gives them a new, stronger set of moves. Their evolved forms can also be unlocked as separate playable characters by clearing the 1P Mode with the respective base Digimon.

All playable Digimon possess an Evolution Gauge that fills as they deal damage in a match. Once the gauge is full, Digimon who can evolve undergo evolution. The Evolution Gauge slowly depletes over time while they are evolved. Once the Evolution Gauge empties, the Digimon devolves to its previous form. The evolved Digimon can also expend the gauge at any time to use their most powerful attack technique, but devolve immediately upon the technique's completion or interruption. Digimon who do not evolve can use their most powerful attack technique only when their Evolution gauge is full. This expends their entire Evolution Gauge, but does not devolve them.

Digimon have two different kinds of evolutions in Digimon World 3: their natural evolutions, and optional evolutions. Natural evolutions are obtained by hitting certain levels: LV 5 for Adult, LV 20 for Perfect, and LV 40 for Ultimate. Optional evolutions are obtained by levelling up certain evolutions (for example, levelling up Greymon would give you Metal Greymon if your partner isn't Agumon, who obtains them naturally) or by increasing a Digimon's nature resistances or stats (for example, Agumon will obtain Skull Greymon by increasing its darkness resistance).

A Digimon can equip up to three evolutions that they have learned at a time. They can switch between these and their base form at any time in-battle by using a turn, and one form can be assigned as their "Battle Evolution" so that they will start all battle encounters in that form. Evolutions can be equipped and unequipped by talking to Dr. Kadomatsu in the Asuka City Digimon Lab, or to Piccolomon in other locations.

Certain compatible pairs of Digimon can Jogress Evolve, which in this game just acts as a powerful attack that requires an MP cost from both participating Digimon. It can be activated in the Tag menu, as an alternative to just tagging out, and any Digimon that can be Jogressed with are marked with a red orb icon in that menu. When activated, a cutscene will show the two Digimon Jogressing and performing one technique in their Jogressed form, before switching to the Digimon that was part of the pair that was not in-battle when the Jogress was activated. The majority of Digimon that can be Jogressed are also available as regular evolution options, but there are three who only appear by Jogressing, all of whom are from Digimon Frontier.

In battle, Digimon have a Blast Gauge that fills up as they take damage. Once it is full, they will immediately undergo Blast Evolution: a temporary evolution into a more powerful form that lasts for several turns. While Blast Evolved, they will have automatic access to that form's Special Move, and all techniques (both Special and loaded) can be used without any MP cost. If a Blast Evolved Digimon is switched out or evolved into another form, the Blast Evolution state ends. Most of the time, a Digimon will Blast Evolve into their next natural evolution that they have not yet unlocked until Level 39, when they unlock their Ultimate form; after Level 39, they will Blast Evolve into other Ultimate Digimon.

There are two types of evolution that Digimon can undergo in battle. When their Evolution Gauge is filled, they can enter a state where, whenever they attack, they will temporarily Slide Evolve into their Beast Form Hybrid form and perform a stronger attack. The Evolution Gauge slowly decreases over time, and Slide Evolution ceases once it is empty.

When a Digimon collects five gold crystals, they are able to perform an Ancient Spirit Evolution. If they make contact with the enemy while initiating the evolution, they will evolve into one of the Warrior Ten (or Susanoomon for the Extra Agnimon and Wolfmon) and unleash one immensely powerful attack, at the cost of emptying the crystal gauge.

Fourteen playable Digimon are able to evolve during matches: Agumon, Gabumon, Piyomon, Tentomon, Patamon, Tailmon, Gomamon, Palmon, V-mon, Guilmon, Flamon, Black Agumon, Black Gabumon, and Black Guilmon. Each of these Digimon has two evolved forms, which each give them a new, stronger set of moves.

All playable Digimon have an Evolution Gauge that fills as they collect orbs of energy, that are dropped by all fighters in a match when they are hit. Each time it fills, they are able to evolve to their next form. Their evolution lasts until they are KO'd, at which point they will respawn in their previous form.

When the Evolution Gauge is filled while a Digimon is fully evolved, or if the Digimon cannot evolve (like the rest of the playable fighters), they become able to use an "Ultra" finishing move.

Digimon can evolve by filling their evolution gauge, which can be done by driving over data patches. Evolution is automatic whenever the gauge reaches particular thresholds. All Digimon begin races in their Child forms (or as Agnimon), with their evolution gauge half-full (1 1/2 bars). If the gauge reaches 2 bars full, they evolve into their Adult forms (or Vritramon, in Agnimon's case); if it reaches a full state (3 bars), they can spend part of their gauge to use their Special Move. Every time a Digimon takes damage, their evolution gauge is depleted. If it falls below one full bar, they devolve to their Baby II form (or Flamon, in Agnimon's case).

Evolution can be managed from a Digimon's stats profile, under the Evolution Route option. Because of this, Digimon in the player's party may be evolved or devolved at any time the player chooses outside of battles. Evolution in Digimon Story is based around pre-set evolution lines, where each individual Digimon species has a short list of Digimon that it can evolve into (usually one, occasionally two or three). To evolve into a particular Digimon, a Digimon must first meet that Digimon's minimum evolution requirements such as level, attribute EXP, stats, Friendship, and Stress all meeting certain thresholds (in the case of Stress and, in some rare cases like Devimon, Friendship, it must not exceed a maximum threshold).

In some special cases (like Dot Agumon), the Digimon may only be evolved into if the player has previously owned a Digimon of the same species, or if they presently have 100% scan data for it.

Some Digimon, such as Armor Digimon, also require that the player obtain a matching item (e.g. a Digimental for Armor Digimon) before they can evolve any Digimon into them. These items are not consumed by the evolution process, so once they have been obtained, the Digimon can be evolved into as many times as the player wants.

Every time a Digimon devolves, its Aptitude stat increases. This increases the Digimon's maximum level cap.

Each of the six playable partner Digimon's evolutions are sorted into unique series of branching paths called Galaxies. To unlock an evolution, the player and Digimon must meet its evolution requirements (usually listed in the Evolution Map menu), which can include:


 * minimum stat thresholds, like Digimon Story
 * the Digimon's current emotional state
 * gameplay performance statistics/records, both in general and for the Digimon specifically
 * amounts of currency owned
 * story events

Additionally, every other evolution that precedes a given evolution on its branch of the Galaxy must also have already been unlocked.

Once the criteria are met, a cutscene plays in battle in which the Digimon's Tamer performs a Digisoul Charge and evolves the Digimon into the unlocked form for the first time; in Agumon's case, Daimon Masaru will also punch an enemy Digimon to invoke his Digisoul, inflicting some damage on it. Once said battle ends, the new evolution becomes available to be freely equipped and unequipped as the Digimon's form in battle in the Evolution Map menu.

The mechanics of evolution in Sunburst and Moonlight are mostly identical to those of Digimon Story. While evolving can still be accessed from Digimon's stat screens, the DigiLab PC at the player's Tamer Home also allows for easy access to managing evolution for all Digimon in the player's possession (in the party, bank, or Farm Islands alike). Evolution options are also somewhat expanded, and it is more common for Digimon to not only have more evolution options, but for those evolution options to have multiple evolution options themselves.

Sunburst and Moonlight also introduce Jogress Evolution, which is available under the "Special Evolution" menu of the DigiLab PC. There are many Digimon, including Digimon who are available through natural evolution, who can be formed by Jogress using specific combinations of Digimon (often, there are multiple viable combinations for Jogressing into the same Digimon). Like natural evolution, however, Jogress Evolution also requires that the new Digimon's minimum evolution requirements be met by the first Digimon selected to be used for the Jogress.

Unlike Digimon Story, Armor Evolution is now managed separately under the "Special Evolution" menu. Otherwise, it functions the same, with both the Digimental item requirement and the minimum evolution requirements.

Digimon can evolve by reaching certain levels: level 11 for Adult, level 25 for Perfect and level 41 for Ultimate. Evolution is temporary, and consumes the player's Digisoul. Some Digimon have stronger stages known as Burst Modes, these need specific items to be unlocked. Other Digimon have alternate Ultimate levels that also require specific items to be unlocked. Jogress Evolution is also possible between specific Digimon.

&
Evolution in Re:Digitize is similar to how it is in the original Digimon World, but the Ultimate level has been added.

Evolutions are unlocked as the player proceeds through the game and reaches the points in which they were obtained in the Digimon Adventure anime. During the first appearance of each evolution (including Skull Greymon), a cutscene will play, adapting their evolution sequence from the anime with in-game graphics, and afterwards, they'll remain evolved for free for the battle. Afterwards, the Digimon can evolve in-battle by paying an SP cost (except Skull Greymon, which is fully unplayable), which is 5 SP for the Adult level and 15 SP for the Perfect level, and will remain evolved for the rest of the battle afterwards, triggering a short scene where they spin around before changing to the next stage and chanting its name. If a Digimon is already at a higher level, the cost of that evolution is removed from the overall cost of their next evolution. Evolving increases stats, resets lowered stats, removes status effects, and changes the Digimon's moves for stronger ones with a higher SP cost. Digimon may also begin fights evolved by equipping the EVO Boost DigiPiece line, which let them start battles in higher levels depending on the level of the DigiPiece itself.

Digimon start at the Child level. While the Baby II to Child evolution of the first episode of Adventure, "Adrift? Island of Adventure!" does happen in the game, it is purely a cutscene, and the Baby II-level Partner Digimon are not playable. Other moments when the Chosen Children's Digimon dip below Child also do happen in the game as they do in the anime, but they just become non-playable during these segments.

During Episode 23, "The Fairy! Piccolomon", Agumon is incapable of evolving, due to Yagami Taichi's worries that Agumon would evolve into Skull Greymon again. As such, the Evolution command is unusable and the EVO Boost I DigiPiece will have no effects. This is solved by the end of the chapter, allowing Agumon to evolve normally again. Also, even after Tokomon evolves back into Patamon and becomes playable again in Episode 26, "The Whispering Imp, Pico Devimon", he is unable to become Angemon again until Episode 44, "Pump and Gottsu are Shibuya-type Digimon", much like in the anime.

Digimon other than the playable ones are shown evolving during the story:
 * A Piyomon, envolved in a dark aura, serves as the final boss of Sub-Episode 2, "Piyomon Runs Amok!". This Piyomon evolved from a Pyocomon of the Pyocomon Village due to eating a DigiTomato, and returns to its previous form after being beaten in battle and exhausting its energy.

Every playable Digimon has two evolutions. Obtaining enough EP will allow a Digimon to evolve into their next stage. While the first and second stage are unique for each character, some of the thirds are shared between two characters (for example, Agumon and Gabumon both evolve into Omegamon).

&
Evolutions are managed at Mikagura Mirei's DigiLab. The mechanics of evolution in the Cyber Sleuth games are similar to those of the earlier Digimon Story games. Almost every Digimon has a list of Digimon that it can evolve from and evolve into. To evolve into a particular Digimon, a Digimon must first meet that Digimon's minimum evolution requirements such as level, stats, Ability, and Camaraderie all meeting certain thresholds. The only requirement to devolve is that the player has previously encountered the Digimon to be devolved into. Every time a Digimon evolves or devolves, its Ability stat increases, which makes it easier to evolve into forms that require higher minimum Ability.

Jogress Evolution can be performed between certain pairs of Digimon. This works the same way as regular evolution, except that the the player must also have the other component Digimon for the Jogress and both Digimon must have maximum Camaraderie. Once the Jogress has been performed, the Jogressed Digimon is treated like any other Digimon in terms of further evolution or devolution: that is, the Jogress cannot be "undone" to get both component Digimon back, and instead, the Jogressed Digimon can only be devolved into either one of the component Digimon forms.

Some Digimon, specifically Armor Digimon and Hybrid Digimon (although the latter are treated as regular levels in this game) also require that the player obtain a matching Digimental or Legendary Spirit item before they can evolve any Digimon into them. These items are not consumed by the evolution process, so once they have been obtained, the Digimon can be evolved into as many times as the player wants.

In the original version of Digimon Story: Cyber Sleuth, Digimon can only evolve into members of the Royal Knights after completing specific late-game quests that each unlock the ability to evolve into one to three of these Digimon. Additionally, in both the regular release of Digimon Story: Cyber Sleuth Hacker's Memory and the Digimon Story: Cyber Sleuth Complete Edition release, there are some Digimon who can only be evolved into once Hacker's Memory has been completed.

Several NPC Digimon characters evolve during the course of the stories.
 * Shiramine Nokia's Agumon and Gabumon become capable of temporarily evolving as Nokia's adventures with them continue. They are depicted as evolving into Greymon and Garurumon, then War Greymon and Metal Garurumon. In Cyber Sleuth Chapter 10, during the fight at Under Zero, Nokia gains the ability to fuse them into their original form: Omegamon of the Royal Knights.
 * When Sanada Arata accompanies Aiba Takumi/Ami or Amazawa Keisuke as a partner, his Keramon is seen in higher evolved forms as the games progress: Chrysalimon, Infermon, and Diablomon.
 * In Cyber Sleuth Chapter 15, Kamishiro Yuuko's Rize Greymon evolves into Gaioumon when she asks it whether it will stay with her, even though she is no longer using the Kamishiro Yuugo avatar.
 * In Hacker's Memory Chapter 16, Date Makiko's Lopmon evolves into Andiramon when she confronts Mysterious Digital Face.
 * In Hacker's Memory Chapter 17, Imai Chitose's Ankylomon fuses with the Angemon that Yuri left with him to form Shakkoumon.
 * In Hacker's Memory Chapter 18, Mishima Ryuji's Cyberdramon evolves into Justimon in response to Ryuji's determination to make amends.

&
Evolution in -next 0rder- is similar to how it is in Re:Digitize, but streamlined. Less time is required for each stage, and it is easier to evolve. Furthermore, Paildramon's dojo allows the player to block certain evolution paths, which helps to evolve a Digimon to the specific one the player wants, and can allow a Digimon to evolve into forms it does not properly fulfill the requirements of. Furthermore, Jogress Evolution is possible in Paildramon's dojo, which will evolve one of Takuto/Shiki's Digimon to the Jogressed stage while devolving the other one one stage.

A new form of evolution added to the game is ExE, short for Extra Cross Evolution. ExE allows the player's Digimon to fuse together in-battle, getting them a major power boost. ExE can be triggered by the player by spending 150 Order Points from both Digimon when they have max friendship with each other, or after both of their Digimon fall in battle randomly. However, ExE can only be used once per day.

Several NPC Digimon characters evolve during the course of the story.


 * Yukimura and Rikka, the partner Digimon of Takuto/Shiki's friends Hirose Kouta and Oofuchi Himari, evolve from their Child-levels to their further levels, all the way to Ultimate. Yukimura also evolves incorrectly into Skull Greymon at one point, due to Kouta forcing the evolution, expecting him to become Mugendramon instead and thinking he could control said Digimon, only for Yukimura to lose control and having to be taken down instead.
 * Several other Digimon also undergo alterations to become Mugendramon during the story, much like how it happened in the postgame of the original Digimon World.
 * During the final part of the story, Analogman possessing Tsuzuki Shoma evolves Omegamon Zwart D into Omegamon Alter-B, a process he calls Altered Super Evolution (変性超進化 Hensei chō shinka; Dub: Ultimate Altered Digivolution). As he explains, he accomplished this by breaking Omegamon Zwart D's mind, as he realized such a process could bring forth altered forms of Digimon other than Mugendramon by watching Kouta's Yukimura evolve into Skull Greymon.
 * Meicoomon evolves to Meicrackmon: Vicious Mode after the White Fang uses a machine to evolve her into said form, then banishes her back to the Next Order universe (having already been there once before). Takuto/Shiki helps her to return to her original World for the second time, where Meicrackmon defeats White Fang.
 * In the International Edition only, Kurorin and Kurocchi evolve throughout the game. In MOD Ship Cave, they fight as Gabumon (Black) and Agumon (Black). In Great Fault Ex Machina, they've evolved to Garurumon (Black) and Greymon (Blue), and then they evolve even further into Were Garurumon (Black) and Metal Greymon (Virus). Their final encounter is in Infinity Cauldron, where they've become Metal Garurumon (Black) and Black War Greymon. After losing, they Jogress into Omegamon Zwart for a moment, only for them to immediately separate.
 * In the International Edition only, Rosemon angrily evolves to Rosemon: Burst Mode after returning to her Palace and seeing that her former minions had pooped everywhere. Takuto/Shiki have to defeat her to calm her down.
 * In the International Edition only, Shine Greymon evolves to Shine Greymon: Burst Mode to help defeat Chaosmon.
 * In the International Edition only, Piemon and Vamdemon are forced to Jogress into Voltobautamon by the Grudgeful Hand who then possesses it so it could try and destroy the World. After it is defeated, it clones the body, reverts the duo back to their prior forms, and then has friendly rematches with Takuto/Shiki.

Natural evolution seems to be unheard of in the Digimon Survive setting. Evolution is only attainable through the power of human children, which makes them desirable to enemies. However, negative feelings in a human can lead to a Dark Evolution instead, where the Digimon goes berserk, magnifying said human's negative side.

In gameplay, how evolution works differs depending on whether a Digimon is a Partner or Free. In either case, evolution increases stats and changes both the normal and special attacks of the evolved Digimon.
 * For Partner Digimon, evolutions are unlocked at certain points in the story. Afterwards, they can evolve through the Evolution menu in-battle. While Digimon normally regain SP once a round is over, an evolved Digimon will instead lose SP (5 SP per turn for an Adult evolution, 10 SP for a Perfect one, 15 SP for an Ultimate one), and they need to pay the same amount to evolve. Evolution can also be undone through the Evolution menu. Partner Digimon will always start a battle in the Child level, which they also have throughout the story. Most Partner Digimon have specific evolution paths with very few deviations, though Agumon has three different choices for every level but Super Ultimate, which instead has two. Which he gets depends on which emotion is highest on Momotsuka Takuma's Karma meter: Harmony will make Agumon evolve into Data-type Digimon, Moral will make him evolve into Vaccine-type Digimon, and Wrathful will make him evolve into Virus-type Digimon.
 * Agumon's evolution into Omegamon works in a slightly different way than the rest, as it is a Fusion with Gabumon. It costs 20 SP to evolve and maintain, and requires Gabumon (in any of his forms) to be deployed as well. Despite being a fusion of both Agumon and Gabumon, only Agumon can initiate it, it causes Gabumon to vanish from the field upon evolving, and Omegamon is considered to only be Agumon in-game. If Agumon then reverts to any previous form, Gabumon will reappear on the field in the exact same place and state he was in before the evolution.
 * For Free Digimon, evolution requires the use of specific items (Mature Enlightenment Slabs for Adult-level evolutions, Perfect Enlightenment Slabs for Perfect-level ones, Ultimate Enlightenment Slabs for Ultimate-level ones), must be triggered from the Status menu outside of combat, and is permanent. Unlike Partner Digimon, Free Digimon have complex evolution trees, although they can only ever get one evolution per level as their evolutions cannot be undone. The DLC Digimon, Guilmon, only has one choice for each level.

Story-wise, evolutions occur as follows:
