Evolution/Video Games

======
Evolution generally follows the same rules, mechanics, and paths as in the Digital Monster Vers. 1–4 virtual pets, from which Ver. S is adapted. All evolutions are one-way, and occur as in-game time elapses depending on how the Digimon is raised.
Unlike the original virtual pets, training has no influence at all on how a Digimon evolves. Instead, the Digimon's affection for the player — i.e. how much the player has interacted with the Digimon on the home screen, and how the Digimon reacts to the player's interactions — affects what the Digimon will evolve into in the same way that the number of times the Digimon undertakes training does in the original virtual pets.
As in the original virtual pets, evolution to the Perfect generation is not guaranteed. Once a Digimon has fought the required minimum of 15 battles to qualify to evolve to Perfect, this is marked on its stat screen by the "Win Rate" label turning red instead of blue.
The game introduces fourteen "Ver. S" Digimon who are created by using the NEW Digitama item to fuse two other Digimon. Unlike the Adult Digimon from the pre-existing virtual pets, each "Ver. S" Adult Digimon (except Gokimon) is able to evolve into two different Perfect Digimon, depending on how it is raised.
Additionally, all Adult and Perfect Digimon from Vers. 1–4 are associated with a "Digimon Fragment" item. Using a Fragment on a compatible Digimon guarantees that when the time comes for the Digimon to evolve, it will evolve into the species corresponding to the Fragment, regardless of any evolution requirements. There are no Digimon Fragments for any of the "Ver. S" Digimon.

======
Digimon evolve after reaching a certain lifespan:
*Baby I > Baby II: 6 hours.
*Baby II > Child: 1 day.
*Child > Adult: 3 days.
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 has a 50% chance to evolve into Kunemon.
*If a Digimon poops too much outside of the toilet, filling its Virus gauge, it'll evolve into Scumon. 
*If a Child-level Digimon is scolded while having its Happiness at its minimum, it'll evolve into Nanimon.
*If a Child-level Digimon fails to meet any evolution conditions when the evolution time comes, it'll evolve into Numemon. 
*If a Birdramon or a Seadramon has max Happiness and Discipline, then goes to sleep with no Tiredness, it has a 30% chance to evolve into Airdramon.
*If a Drimogemon has max Discipline and Defense, then goes to sleep, it has a 30% chance to evolve into Monochromon.
*If a Shellmon or Whamon has lived exactly 200 hours and gets praised or scolded, it has a 30% chance to evolve into Coelamon.
*If a Vegimon has max Discipline and fights 50 times, then goes to sleep, it has a 30% chance to evolve into Igamon.
*If an Adult-level Digimon is at least 15 days old, has a Discipline below 50%, and is then scolded, it has a 50% chance to 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.
*If the player brings a Mamemon to the Guardromon who offers to remodel for 2000 bits, there are three possible outcomes:
**"It didn't work": nothing happens.
**"It was successful!": 0,45% chance. Mamemon evolves into Metal Mamemon.
**"It didn't work, but...": 0,11% chance. Mamemon evolves into Giromon.
*Death Evolutions (10% chance of triggering after being defeated in battle):
**Any Child-level Digimon > Bakemon
**Angemon > Devimon
**Birdramon or Cockatrimon > Hououmon
**Metal Greymon or Megadramon > Skull Greymon
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—Numemon, Otamamon and Bakemon—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 Masters and a Chimairamon. In the final dungeon, Millenniumon is fought first in the form of either Chimairamon or Mugendramon, before returning to its true Milleniumon form to be fought again.
======
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, which is formed by Jogressing an XV-mon from Digitama #1 with a Stingmon from Digitama #2 (rank 2), the "Wormmon" Digitama. This line adds Paildramon and Imperialdramon as, respectively, 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—V-mon, Hawkmon, Armadimon, Patamon, Tailmon—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 that 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, as long as the appropriate Digimental is equipped, the Armor Evolution technique is automatically available in the Digimon's sixth technique slot (reserved for techniques bestowed by equippped Digimentals).
======
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—V-mon, Hawkmon, Armadimon, Patamon, Tailmon and Wormmon—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) and not every Digimon has any possible evolutions. 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.
Upon evolving, a Digimon's stats increase, while upon devolving, they decrease. Level may increase or decrease depending on the Digimon's current level and the base level of the Digimon it's becoming. In both cases, it gains a new Trait if it's the first time it's taken its current form, and its techniques change to those of its current form. Every time a Digimon devolves, its Aptitude stat increases, and evolution may also increase Aptitude. This increases the Digimon's maximum level cap. However, the player can't devolve Digimon until obtaining Phil's Devolve Chip, and how high they can evolve is limited by their current Tamer Rank.
Several evolutions and devolutions happen during the story:
*Black Agumon evolves into Dark Tyranomon off-screen after being defeated by the Player. As he explains later as Pagumon, this was a Dark Evolution born from the lack of a good Tamer. Later on, after being reborn as Pagumon, he retakes his true form of Andiramon (Deva) by using the Core Shard.
*Mugendramon devolves into Skull Greymon after using Phil's Devolve Chip, weakening him enough for the Player to fight him.
*Kain uses the Data Core on his Atlur Kabuterimon (Red) to evolve it into Gran Kuwagamon. However, the overwhelming energy of the Data Core causes it to go out of control, then self-destruct.
*After the Player defeats Chronomon Destroy Mode, he's cleaned of the darkness and becomes Chronomon Holy Mode.
*Daimon Masaru's Agumon evolves into Geo Greymon to fight King Etemon. Off-screen, Thoma H. Norstein's Gaomon evolves into Mach Gaogamon for the same reason.
======
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 Lost Evolution is similar to how it was in Sunburst/Moonlight. The main difference is the introduction of Evolution Trees, which group Digimon in them and show what they can evolve into, with some Digimon being able to move into other trees. Furthermore, not all evolutions are usable at first, with several of them being locked until the player finds and revives their Evolution Plates, which either drop from random encounters or are found as part of the story. Successfully reviving them and reinserting them into their corresponding evolution trees will allow the player to evolve into that Digimon, as well as unlocking other Digimon that may require that specific evolution (such as Geo Greymon requiring Greymon to be revived).
Digimon other than the playable ones are shown evolving during the story:
* A Pico Devimon Shū/Kizuna and Asuka met while looking for the Black Box evolved into Devimon off-screen after Shū/Kizuna revived the Devimon Evolution Plate. Later, it is shown to have evolved into a Venom Vamdemon, and later still it returns as a Belial Vamdemon.

====Player-related====
Evolution in Re:Digitize is similar to how it is in the original Digimon World, but the Ultimate level has been added. 
*Baby I to Baby II evolution will always happen after a few hours and there's only one choice for each Digimon. 
*Baby II to Child evolution will always happen after a day. There are five possibilities for each Digimon, which they evolve into depends on their highest stat and their current weight.
*From Child onwards, evolution is not guaranteed and Digimon need to meet at least some of these criteria to evolve, the amount depends on the level (3 for Adult, 5 for Perfect, 6 for Ultimate) while the criteria depend on the evolution itself: battle stats (HP, MP, Attack, Defense, Speed, Intelligence), Weight, Mistakes (both can be above or below a certain number), Happiness, Discipline, Battles fought, learned Techniques, Tamer/Decode level.
While evolution is completely one-way in gameplay, in-story, Digimon can devolve if they use too much energy and can't evolve again at will afterwards, which happens to both V.V. (from Aero V-dramon to V-mon, then from Ulforce V-dramon to V-dramon) and Tyranomon (from Rust Tyranomon to Tyranomon) during the Scheme of the Demon Lords chapter. The crossover characters from the different anime series use their own rules and methods, with Izumi Koshiro realizing the difference in their evolution lies in their different Digivices.
Certain evolutions require specific criteria to be fulfilled before they can be accessed. These include:
*Story progression: Beelzebumon, Rust Tyranomon, Alphamon, Mugendramon.
*Digimon to be returned to the Village of Beginnings: Monzaemon.
*Victories in the Colosseum: War Greymon ("Taichi and Agumon's Evolution!"), Metal Garurumon ("Yamato and Gabumon's Friendship!"), Garudamon ("Sora and Piyomon's Love!"), Magnamon ("Radiance of Miracles"), Dukemon ("Takato and Guilmon"), Lilithmon and Seraphimon ("Angels and Demons")
*Death of a previous Digimon: Victory Greymon (Dukemon), Z'd Garurumon (Metal Garurumon)
If Taiga talks to Great King Scumon in the Underground Waterway Labyrinth, he can turn Digimaru into a Scumon or return him to his previous form if he's currently one.
Furthermore, most Digimon above the Child-level 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. They're implied to be left-behind data of dead Digimon, as Lili obtains Lilithmon's from her corpse and several of them are found behind Bolt Unlocker doors, prisons, in the Digitower 70th floor.

====NPC-related====
Several NPC Digimon characters evolve during the course of the story:
*During the story, Vitium evolves twice. It starts as Vitium Baby, becomes Vitium Adult before the party meets it again in Signpost Woods, and reaches its ultimate state as Vitium Ultimate for the final battle.
*After being defeated by Vitium Adult, Nicolai Petrov and Sashenka trained for six hours in the Village of Beginnings' Gym. This made Sashenka evolve from Gaomon into Gaogamon. Later on, at some point before the team battle against Rindou Akiho and Kuga Yuuya, he evolved into Mach Gaogamon. For the 40th floor Free Battle: "Let's have a Showdown", he evolves into Mirage Gaogamon.
*Thanks to the Colosseum 20th floor Tournament: "Fighting Spirit!", Akiho regains her fighting spirit, which lets Digitorin evolve from Piyomon into Birdramon. Later on, at some point before the team battle against Nico and Mikagura Mirei, she evolved into Garudamon. For the 40th floor Free Battle: "I'm the Nyanko Tamer", she evolves into Hououmon.
*Yagami Taichi evolves his Partner Digimon, Agumon, into War Greymon for the Colosseum 1st floor Free Battle: "Taichi and Agumon's Evolution!".
*Ishida Yamato evolves his Partner Digimon, Gabumon, into Metal Garurumon for the Colosseum 1st floor Free Battle: "Yamato and Gabumon's Friendship!".
**During the Heavenly Hall Free Battle: "The Final Test", Taichi and Yamato fuse War Greymon and Metal Garurumon into Omegamon.

*Lili and Sebastian evolve their Partner Digimon, Catherine the Numemon and Angemon, into Monzaemon and Holy Angemon, respectively, for the Colosseum 30th floor Free Battle: "Lili and Sebastian". They evolve again into Lilithmon and Seraphimon, the former using Lilithmon's evolution item, for the 40th floor Free Battle: "Angels and Demons".
*Professor Petrov's Rize Greymon evolves into Shine Greymon for the Colosseum 40th floor Tournament: "The strongest is...".
*According to Greymon, the master of Night Canyon, Were Garurumon, became the strongest after evolving from Garurumon sometime before Taiga talked to him.
The following evolutions are exclusive to Digimon World Re:Digitize Decode:
*Shinomiya Rina's V.V. evolves from V-mon into V-dramon for the Colosseum 20th floor Free Battle: "No longer a V-mon", then Aero V-dramon for the 40th floor Free Battle: "The Final Showdown!". He returns to V-mon after exhausting his power saving Rina, but recovers his V-dramon form after Rina's Digivice absorbs Lilithmon's power. He evolves into Ulforce V-dramon for the final fight against Barbamon, only to devolve into V-dramon soon after when Demon starts taking Rina's Demon Lord powers.
*Yamato's Gabumon evolves into Were Garurumon for the Colosseum 30th floor Free Battle: "I'm not a kid!".

*Beelzebumon appears on the 60th floor of Infinity Mountain X-Evolved into Beelzebumon (X-Antibody).
*After activating the first Memorial Stella, Jijimon sends Taiga a mail, telling him the Digimon at the Village of Beginnings were changing, as if they wanted to evolve, and asks him to help them. These include:
**A Botamon in the Restaurant at night who loves the night so much it evolves into Sakuyamon.
**A Bubbmon who wanted to go to the Submerged Ruins gets so excited to do so, it evolves into Metal Mamemon
**A Budmon who asks Taiga to stop Tyranomon, who was charring the meat at the Meat Farm, later evolves into Agumon thanks to the meat Taiga saved.
**A Budmon who wanted to see its grandpa, but couldn't because it went to the Ancient Bone Swamp and a Baby II was too weak to go there. Taiga tells it to evolve but Budmon says it can't, then asks for a Digimushroom. It then evolves into Woodmon.
**A Budmon at the item shop adores Ice-Water Digimon. Upon seeing Taiga's Ice-Water Partner Digimon, it evolves into Yuki Agumon.
**A Bubbmon at the Angel Clinic hates low-discipline Digimon. Being shown one disgusts it, but also attracts it, causing it to evolve into Lady Devimon.
**A Dodomon is exhausted after training and asks Taiga for a vegetable that can help it. Taiga gives it a Super Carrot, which energizes it enough to make it evolve into Gaomon.
**A Dodomon wanted to open its own shop but had nowhere to do it. After Taiga tells it of the Drill Tunnel in the Night Canyon, it evolves into Master Tyranomon to make it its own.
**A Dodomon at the Restaurant wants to stop feeling hungry. Taiga convinces it it's proof that it's alive, so it asks him for three Well Done Meats instead. These make it so full that it evolves into Megalo Growmon (Orange).
**A Dodomon who felt energized thanks to how lively the Village of Beginnings was, which let it evolve into Wanyamon.
**A Gigimon picked up trash for Tonosama Gekomon outside DoReMiFa Mansion for money to buy a Meat Field, then left the job after getting tired of it. However, it hadn't accrued enough money and didn't know how to get more. It then evolved into Gekomon.
**A Jyarimon in terrible pain. Taiga gives it a bandage, curing it and evolving it into Boltmon.
**A Jyarimon wants to see a Digimon that's very strong. If Digimaru is strong, Jyarimon evolves into Death Meramon.
**A Jyarimon asks Taiga to bring Parrotmon back. After Taiga does so, Jyarimon is filled with courage and evolves into Gigimon.
**A Jyarimon wanted to see a Digimon from a Tamer with a high Decode level. It thought Digimaru, who met that criteria, was so amazing it was unfair, then used that as reference to evolve into Metal Garurumon.
**A Mochimon was scared of a life of fighting. After learning Taiga had fought over 200 times, it realized everyone was pushing themselves to their limits and decides to fight like Taiga and the Royal Knights, evolving into Metal Greymon (Virus).
**A Mochimon wanted a cherry-coloured vegetable. Taiga gives it a Cherry Radish which evolves it into Vegimon.

**A Poyomon in the Item Shop evolves into Ikkakumon a few days after Taiga teaches it how to fish. After mastering fishing, it evolves into Zudomon.
**A Tokomon who was training in the Gym to evolve but was too fatigued to do the last push. With Taiga's help, it trains in the Punch Blocking machine once, then evolves into Grappu Leomon.
**A Tokomon who thought it could hear God's voice. After Taiga agrees with it, it evolves into Holy Angemon. After Taiga shows it the Light Fragment from Lucemon, it evolves again into Seraphimon.
**A Tokomon who wanted to evolve into a Beast Knight Digimon becomes Mirage Gaogamon after seeing Taiga's Full Moon Claws.
**A Tunomon couldn't get the hang of a training and wanted a Training Manual to help it. Through merely training in its mind with it, it evolved into Mach Gaogamon.
**A Tunomon who wanted to see heroic battles at the Colosseum and become a Digimon who could fight them got frustrated at seeing Taiga and Digimaru, who got to the 40th floor, then evolved into Saber Leomon.
**A Wanyamon at the Angel Clinic wanted something wild and woody as food. Taiga gave it a Digipine which made it evolve into Gaogamon.
**A Wanyamon at the Gym wanted some Scratchy Grass to recover from its training fatigue. After getting it, it evolved into Renamon. After it loses to Taiga in a hide-and-seek game in the Train Garage, it evolves again into Kyubimon.
**A Yuramon who was amazed at Guilmon's statue and wanted to make one itself. After Taiga convinced it it could, it evolved into Budmon and left on a journey, where it evolved once again into Gomamon (shown through a Digitter message). When Taiga meets it again in Powdery Cliff, it had evolved again into Vikemon.
**A Yuramon who wanted to become the biggest and strongest Digimon asked Taiga for money to buy food. The next day after Taiga gave it 1000 bits, it evolved into Whamon thanks to eating and drinking like crazy.
**A Yuramon really loved cannons. If Digimaru has a cannon, it gets excited and jealous, then evolves into Z'd Garurumon.
======
Evolution is a fairly long process, but becomes easier as you get further into the game. Most Digimon require other Digimon of a certain type and level to be used as evolution material. The Digimon you wish to evolve must be temporarily replaced in your party with another Digimon. When you select the Digimon you want to evolve, you are given 1 or more choices of Digimon to choose from, each with a different requirement.
The evolution requirements are: Your Digimon to be at its maximum level, at least 1 or more Digimon at a certain level, a number of Data dropped by a Digimon of a matching type, and a large number of Bits.
For example, in order to evolve Greymon to Metal Greymon your Greymon needs to be Level 20, you must have 10 Red Perfect Level pieces of Data, A Red Digimon at level 8, a Blue Digimon at level 3, and a Purple Digimon at level 3. The Bits charged will depend on the Digimon.
======
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 Brave Heart playing, 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, 15 SP for the Perfect level, and 30 SP for the Ultimate 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. Some fights will allow the Digimon to start at their evolved forms, in some cases replaying the stock footage cutscenes, most notably before the second Apocalymon fight, where all the Adult and Perfect footage plays in a row, except for Agumon and Gabumon who use their warp evolution footage instead. 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, from 1 to 3.
The evolution into Omegamon works somewhat differently from the rest. It can only be used in New Game +, requires both Agumon and Gabumon to be in the party and evolved into their Ultimate forms, costs 0 SP, and fuses them together, though the evolution animation only shows the Digimon that initiated it. Upon starting the fusion, War Greymon and Metal Garurumon's remaining HP% and SP% are averaged out, with Omegamon keeping that percentage of his own HP and SP. Omegamon inherits only the DigiPieces from the Digimon that initiated the fusion.
Digimon start at the Child level, except for Tailmon who starts at the Adult level and cannot go below it. 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. The same applies to Tailmon's Child form, Plotmon.
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. While this only affects the story as he isn't playable during this part, in Episode 53, "The Dangerous Game! Pinochimon!", Ishida Yamato's anger and doubts cause Gabumon to be unable to evolve to face Kiwimon. After the first fight against Apocalymon in Episode 62, "The Final Dark Digimon", they use their to return all Digimon to their base forms, though this only affects the story and they are incapable of using this move in-battle.
Unique to the game, after the first fight with Apocalymon, the player can unlock optional battles for every Chosen Child but Taichi and Yamato if they got their individual bond rankings to at least 35. Starting each of these battles unlocks the Ultimate Evolution for the respective Chosen Child, with cutscenes showing Warp Evolution sequences created for the game.
Due to spending a while separated from their Chosen Children, Agumon and Tentomon can only evolve as far as their Adult forms in Episode 64, "Our War Game, Beginning". During their fight against Infermon in the same chapter, they attempt to super evolve into their Perfect stages, but Infermon attacks them during the evolution and stops it. Parts of Metal Greymon's footage are played during this cutscene, though without Brave Heart playing. This restriction is lifted in Episode 65, "Our War Game, Middle", allowing them to evolve all the way to Ultimate once again. However, EVO Boost pieces beyond EVO Boost I will have no effect on Agumon and Tentomon, but they will on Gabumon and Patamon.
During the crossover episode, all the guests will have their Digimon take the highest level they could in their own series without fusing. While their base forms appear in the game as well (with the exception of Gumdramon), they exist only in the story. Their unique evolution methods (Armor Evolution, Matrix Evolution, Spirit Evolution, Super Evolution) are neither named nor commented on, other than Kanbara Takuya evolving into a Digimon, though even in this case no more detail is given.
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.
*A Botamon that hatched from a Digitama in the Village of Beginnings evolved into Koromon in Episode 17, "Adventure! Patamon and I".
*After Nanomon caused Etemon to sink into the power of darkness in Episode 24, "Perfect Evolution! Metal Greymon", the latter fused with the Dark Network, becoming Etemon Chaos. He reappears in Episode 54, "Metal Etemon's Counterattack", having evovled into Metal Etemon after surviving in a hellish world with the purpouse of being reborn and taking revenge on the Chosen Children.
*In Episode 34, "Mammon, the Great Clash at Hikarigaoka!", Taichi remembered how he met a Koromon in the past, before the events of the game, and how that Koromon then evolved into Agumon and Greymon.
*With the prophecy fulfilled, Vamdemon returned to life as Venom Vamdemon in Episode 48, "The Resurrected Venom Vamdemon".
*In Episode 54, "Metal Etemon's Counterattack", Leomon explained that after being bathed in the light of the Digivices, he became capable of warp evolving into Saber Leomon. However, he couldn't control the evolution well and soon returned to his usual form.
*A Digitama hatched into Kuramon in Episode 64, "Our War Game, Beginning". It then quickly evolved into Tsumemon and Keramon. After facing the Chosen Children, it evolved into the Perfect-level Infermon, skipping the Adult level entirely. After fighting War Greymon and Metal Garurumon in Episode 65, "Our War Game, Middle", it evolved one last time into Diablomon.
======
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 (depicted only in Hacker's Memory), 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 14, a Numemon successfully tricks Takumi/Ami into defeating multiple Shakomon for their shells. It then absorbs them, causing it to evolve to Karatuki Numemon. Now that the Tamer had done their job, it attempts to kill them as they had supposedly outlived their usefulness but this instead resulted in its death via self defence. 
* 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 the same chapter, Mikagura Mirei has her Angewomon & Lady Devimon fuse together to become Mastemon.
* In Cyber Sleuth Chapter 19, Lucemon of the Seven Great Demon Lords evolves to Lucemon: Falldown Mode then Lucemon: Satan Mode but is defeated in all three battles with its third defeat resulting in its death. Belphemon: Sleep Mode evolves to Belphemon: Rage Mode with its second defeat also resulting in its death. In the same chapter, Etemon angrily evolves to Metal Etemon and tries to save his best friend Tawa Reiko after she was kidnapped by Jimmy KEN. It teams up with Keisuke and is able to defeat the Hacker, only for Reiko to appear and state that she hadn't been kidnapped and was friends with Jimmy and had been invited to the concert - not kidnapped.
* In Hacker's Memory Chapter 7, Sistermon Blanc and Sistermon Noir (Sistermon Ciel in some versions) evolve to their Awakened forms to fight Nokia and Amasawa Keisuke.
* In Hacker's Memory Chapter 11, a Togemon evolves to Lilimon after drinking Nanomon's potion that was intended to cure its illness. It had a side effect however, causing Togemon to go on a rampage. After Keisuke defeats it, it comes back to its senses then evolves to Lilimon with Nanomon figuring that must've been a side effect of the medicine it had created. Whether that is actually the case is unknown. Regardless, it decides it will create more of it and give it to other Digimon so they become super powerful for its own amusement. 
* In Hacker's Memory Chapter 13, Douguchi Lily's Kyubimon evolves to Taomon to fight Dagomon. In the same chapter, Yasu's Gaomon evolves to Gaogamon as a result of his happiness at being praised by Shiramine Nokia (who he had a crush on) after he and Amasawa Keisuke defeat a group of evil hackers.
* Mishima Ryuji's Arkadimon evolves multiple times by absorbing other Digimon.
* 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 the same chapter, a Megalo Growmon angrily evolves to Megidramon due to a powerful desire to get revenge against Ryuji and Arkadimon who had killed and absorbed its friends with the exception of Leomon. It was unable to control the power though, and after being defeated by Leomon and Keisuke was able to revert back to Megalo Growmon...though it had to be talked down and told that its now deceased friends wouldn't want to see it in its current state first.
* In Hacker's Memory Chapter 18, Mishima Ryuji's Cyberdramon evolves into Justimon in response to Ryuji's determination to make amends. In the same chapter, Mishima Erika and Wormmon fuse together to become Hudiemon.
* In Hacker's Memory, after Keisuke defeats Volcamon in the Master Cup it evolves to Pile Volcamon. Keisuke then defeats it again.
* In Hacker's Memory, the Matadrmon that trolled Nogi Yuu by pretending to be a mask for years is defeated by Keisuke and reverts back to its mask form, which Yu throws away. At some point after that it evolved to Grand Dracumon and tries to take over the World via the Abyss Server but is killed by Keisuke and his friends. As it was a vampire though it was quickly reborn and tries again. This happens infinitely, though after the first time is just the game allowing the player to fight it as much as they want.
* Most characters evolve their Digimon offscreen as part of Domination Battles.
=== & ===
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.
* After being defeated by Takuto/Shiki, Imperialdramon: Dragon Mode evolves to Imperialdramon: Fighter Mode. After being defeated again, it evolves once again to Imperialdramon: Paladin Mode. It is then defeated a third time.
* Lucemon of the Seven Great Demon Lords evolves to Lucemon: Falldown Mode and Lucemon: Satan Mode to fight Takuto/Shiki.
* A Keramon evolves multiple times all the way to Armagemon in an attempt to destroy the World but is defeated. It then hangs out in the City and frequently switches between all of its forms whilst there.
* 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. 
* 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.
In either case, evolution increases stats and changes both the normal and special attacks of the evolved Digimon.
Story-wise, evolutions occur as follows:
Story evolutions in Digimon Survive 	Story evolutions in Digimon Survive	Story evolutions in Digimon Survive	Story evolutions in Digimon Survive 	Story evolutions in Digimon Survive 	Story evolutions in Digimon Survive
Human/Digimon Pair 	Part 	Route 	New Evolution 	Description 	
Momotsuka Takuma & Koromon 	Prologue 	N/A 	Agumon 	After meeting Koromon for the first time, Takuma is attacked by a Gottsumon. Koromon tries to protect him, which makes Takuma protect Koromon in turn. Realizing they were allies, Koromon evolves into Agumon. 	
Momotsuka Takuma & Agumon 	Part 1 	N/A 	Greymon, Tyranomon or Tuskmon 	During the fight against, Takuma wishes to run away in fear as they're overpowered by the powered-up Digimon, who had also called allies to the fight. However, Agumon convinces him not to give up, which gives Takuma the courage to continue. Agumon is then filled with power, evolving into his Adult form (Greymon, Tyranomon or Tuskmon, depending on Takuma's Karma Meter). 	
Hinata Minoru & Falcomon 	Part 2 	N/A 	Diatrymon 	After the party meets back with the Professor, Hinata Minoru wants to be a hero and protect him, but is too scared to do so. Falcomon convinces him that he can, which gives Minoru the courage to pursue his dream. This allows Falcomon to evolve into Diatrymon. 	
Shibuya Aoi & Labramon 	Part 2 	N/A 	Dobermon 	During the fight against Fangmon, Shibuya Aoi's underconfidence makes her scared. Labramon convinces her she is far more courageous than she realized, since she had not ran away yet. Aoi regains her courage thanks to that, whichs let Labramon evolve into Dobermon. 	
Kimishima Saki & Floramon 	Part 3 	N/A 	Vegimon 	During the fight against Cyclomon, it calls out Kimishima Saki for not doing her best in combat and not genuinely caring about rescuing Tominaga Ryo, who he had hurt before. Saki is affected heavily by this, as she realizes he is right, and she only did what she did because she wanted to be seen as a good girl who did the right thing. Floramon tells her that she had an amazing heart and just needed to listen to it, which makes Saki realize that she truly did want to save Ryo. This allows Floramon to evolve into Vegimon. 	
Tominaga Ryo & Kunemon 	Part 4 	Truth 	Flymon 	When Kunemon is wounded protecting Ryo from Palmon, Piyomon and Patamon, Ryo wonders why Kunemon cares so much about protecting him, and why the other three were so stubborn since they didn't look serious; he realizes that made them like himself, never giving up even if it was pitiful. He acknowledges Kunemon's determination, and shows his own, emulating Takuma. This allows Kunemon to evolve into Flymon. 	
Shinonome Miu & Shakomon 	Part 4 	N/A 	Shellmon 	After Shinonome Kaito, Piyomon and Patamon are hurt protecting Shinonome Miu from Garurumon, in tears, she asks Shakomon what she should do, to which Shakomon asks her what she wanted to do. Realizing she does not want Kaito to die after fighting with him, nor Piyomon and Patamon after lying to them about being a sorceress, and she wants to protect them instead, she asks Shakomon to protect Kaito. Shakomon starts glowing, proclaiming how happy she is that Miu has been honest with her feelings, because her whole-hearted wish will make Shakomon as strong as Miu needs her to be. Shakomon then evolves into Shellmon.
