Dark Evolution

Dark Evolution (暗黒進化 Ankoku shinka or ダーク進化 Dāku shinka; Dub: Dark Digivolution) is a corrupt form of normal evolution that is typically triggered when a Digimon falls under some sort of negative influence. A Dark Evolved Digimon is typically very powerful, but also dangerous, aggressive, and uncontrollable.
=Overview=
A common theme with Dark Evolutions is the influence of emotion, either the Digimon's own or that of a human partner. Intense negative emotions, such as anger, hatred, hubristic recklessness, or despair, are what generally triggers Dark Evolutions.Digimon Adventure tri.: "Coexistence" In moments where these emotions are so overwhelmingly powerful, a Digimon may undergo Dark Evolution due to their influence. There are also cases where some external force compels a Digimon to undergo Dark Evolution.
Generally, Digimon who are Dark Evolved are totally uncontrollable and unresponsive to their human partner. They are aggressive and indiscriminately destructive, if not genuinely evil.
It is also common for Angel Type Digimon to have demonic Fallen Angel or Demon Lord Type counterparts that they transform or evolve into when they "fall from Heaven" to the Dark Area, which in some cases is the result of them pursuing some negative emotional compulsion, such as anger, resentment, or self-righteous rebellion, that brings them in defiance of God's will. This resembles the basic idea of Dark Evolution.

======
In "Dark Evolution! Skull Greymon", Yagami Taichi is determined to try and make Agumon to evolve into a Perfect Digimon so that they can stand up to Etemon, but he totally neglects what Agumon actually wants and tries to force it to happen. When they are fighting another Greymon under Etemon's control in the Colosseum, Taichi takes advantage of his knowledge of evolution as triggerable by the threat of harm to a Digimon's partner, and tries to bait the enemy Greymon into attacking him. As Gennai later observes, this is "the wrong kind of courage", so this incorrectly activates the Crest of Courage and causes Agumon to Dark Evolve into Skull Greymon. Skull Greymon immediately runs wild, destroys both the enemy Greymon and a section of Etemon's Dark Network with a single , and causes major damage to both the Colosseum and the surrounding architecture. He does not respond to any of Taichi's attempts to communicate with him, and easily overpowers all the Digimon who try to stop him, but he quickly runs out of energy and devolves back into Koromon. Afterwards, when Gennai contacts the Chosen Children, he counsels them that evolving to Perfect requires raising their Digimon correctly.
The experience of causing Agumon to Dark Evolve traumatizes Taichi, and for a while he is afraid to fight or evolve in case he makes another mistake and causes Agumon to Dark Evolve again. In "The Fairy! Piccolomon", Piccolomon puts Taichi and Agumon on a training course that, after an illusory encounter with a younger Taichi, restores their confidence that they can evolve correctly.

In "The Evil Ring's Magic Runs Wild" the Digimon Kaiser abducts Agumon, enslaves him with an Evil Ring, and attempts to forcefully Dark Evolve him into Metal Greymon. At first, his experiments fail, and Agumon evolves into Skull Greymon. The Kaiser is unable to control Skull Greymon at all; when he first deploys Agumon to fight the Chosen Children, Skull Greymon runs wild until it runs out of energy and devolves.
In "The Enemy is Metal Greymon", after further failed laboratory attempts to create Metal Greymon that just result in Skull Greymon again, the Digimon Kaiser concludes that Evil Rings are not powerful enough to process all the data needed to control Perfect Digimon. He then develops the Evil Spirals to overcome this and other shortcomings with the Evil Rings, uses one on Agumon, and successfully Dark Evolves him into a virus Metal Greymon. This time, not only is the Kaiser able to control Metal Greymon, but Agumon stays in the Metal Greymon form indefinitely. He does not devolve until V-mon (as Lighdramon) frees him from the Evil Spiral in "Blue Lightning, Lighdramon".

After being separated from Wallace and Gummymon, Chocomon Dark Evolves into Wendimon out of loneliness and sorrow at losing Wallace, and desperation to see him again and to "go back" to the way things were. Because of this, Yagami Hikari is able to sense its presence as a "crying Digimon" (泣いているデジモン). His anger and despair when Wallace refuses to go with him causes him to Dark Evolve again into Andiramon, and then again into Cherubimon when the Chosen Children's Digimon corner him. Dark Evolving gives Chocomon increasingly potent dark powers, including the ability to abduct Chosen Children and confine them to a dimension within itself, and to reverse aging.
======
In "The Kindhearted Hero, Leomon Dies!", Matsuda Takato is absolutely consumed by rage and a thirst for vengeance against Impmon (as Beelzebumon), after Beelzebumon kills Leomon. His anger and orders to make Beelzebumon pay force Guilmon to evolve into Megalo Growmon and attack Beelzebumon in a mad frenzy, culminating in Takato ordering him to evolve even further than he ever had before into an Ultimate Digimon. In response, Culumon's powers are triggered (causing him great pain and dread) to Dark Evolve Megalo Growmon into Megidramon. Takato's D-Ark breaks as a result.
When he sees Megidramon, Takato is immediately horrified and regretful of what he has caused Guilmon to become. In "The Name's Dukemon! The True Ultimate Evolution", Megidramon runs wild and engages in a furious fight with Beelzebumon, but Beelzebumon eventually overpowers and defeats it. Megidramon does not devolve for some time until Takato reaches through to him.
Megidramon's abnormal evolution triggers a Digital Hazard so severe that it threatens both the Digital World and the Real World; when Hypnos detects it, they recognize it as the worst that they have ever seen. The Digital Hazard subsides once Beelzebumon knocks Megidramon out.

In "The Day of Parting - The Strongest Enemy: Thoma!", Daimon Masaru is overcome with overwhelming rage at the apparent betrayal of Thoma H. Norstein. He manifests a dark Digisoul that triggers a Dark Evolution in Shine Greymon, transforming him into Shine Greymon: Ruin Mode, a dark version of Shine Greymon: Burst Mode.
In "Destructive Power, Shine Greymon Runs Wild", Shine Greymon is unable to control the Ruin Mode state and goes on a rampage, indiscriminately attacking both Mirage Gaogamon and the city around them. At first, Masaru continues to press the point and demand that Shine Greymon make Thoma pay for everyone that he's betrayed, but Daimon Chika and Bancho Leomon snap him out of it and make him realize what he has done to Shine Greymon, but Shine Greymon does not respond to his cries for him to stop. Bancho Leomon tells him that a Burst Mode running wild cannot be stopped, and that they have no choice but to wait for Shine Greymon to burn himself out. When a tear lands on Masaru's Digivice Burst, Shine Greymon's Ruin Mode state ends and he reverts into a Digitama. Bancho Leomon and Lalamon point out that Agumon may no longer have any memories of his life with Masaru after he hatches, if he ever hatches again at all.

This energy forces Tailmon (as Nyaromon) to Dark Evolve into Ofanimon: Falldown Mode. She then fuses with Raguelmon to become Ordinemon, triggering the beginning of the consumption of the Real World by the Digital World and thus fulfilling Yggdrasill's plan.
Some secondary sources, such as the Battle Spirits card game, also describe Meicoomon's evolutions into Meicrackmon: Vicious Mode as Dark Evolutions. However, Meicoomon's transformations are classified by official Digimon Adventure tri. material as mutation (変異 Hen'i), not Dark Evolution, although they do share the similarity of being caused in part by negative emotion.Meicoomon: EVOLUTION | Digimon Adventure tri.

He attacks Done Devimon in a berseker rage, and Tokomon observes that if he is not stopped, he will become just like Done Devimon.

Minase Akiharu theorizes that the evolution of Kemonogami is linked to human children is heavily affected by said children's emotions. As such, an unstable mind, caused by such thing as fear, anger, sadness, or suppression, can cause their Digimon to evolve into uncontrolled forms. This process is referred to as Dark Evolution at certain times during the story.
Minase Haruchika's Huanglongmon dark evolved to Master due to his hatred and desire for revenge against Minase Yukiha for sacrificing him. He then told Master to absorb him, which he did with this having Haruchika control Master's actions. In the truthful route, after Master was defeated, Haruchika was ejected which caused Master to slide evolve into Huanglongmon: Ruin Mode.
At the end of Part 5 (outside of the truthful route, where this doesn't happen), after Kayama Shuuji completely broke down due to Archnemon's manipulations and his own weakness and trauma, he physically attacked his own Partner, Lopmon, after emotionally abusing him during their entire partnership. This caused Lopmon to be covered in a black fog, unlike the golden glow of a normal evolution. Shuuji then kept attacking him to force him to evolve, despite Lopmon's fear, which ultimately caused Lopmon to Dark Evolve into Wendimon and go berserk as a response to Shuuji's rage. As Wendimon, he destroyed Mega Seadramon in one hit, but then he ate Shuuji showing how much he had lost himself. Afterwards, Shuuji yells from within Wendimon that he deserved to die showing he hadn't died yet and is why Wendimon didn't die like Kunemon had when Ryo had died. This spurred Agumon's evolution to Perfect as, realizing Shuuji was still alive, they wanted to beat up Wendimon to revert him back to Lopmon so they could save both in the hopes it would cause Shuuji to be ejected from the much smaller body. This doesn't happen though, as the Kenzoku kill Wendimon before they can save them.

The Digivice Ver.Complete adds Dark Evolutions as special evolution lines for Agumon and Gabumon. If either Digimon loses two battles in the same stage, their usual Perfect and Ultimate evolutions are replaced with, respectively, Skull Greymon and Black War Greymon, and Were Garurumon (Black) and Metal Garurumon (Black), and they lose the ability to access any other Perfect or Ultimate forms other than these ones. They exit their Dark Evolution lines if they lose two more battles in the same stage.
Dark Evolution is only available once the respective Digimon is unlocked and the Omegamon requirement is unlocked.
