Chaosmon is a Unique Digimon. Normally, when a DNA Digivolution occurs, the DigiCores of the two fellow Digimon are completely fused and are reborn as a new Digimon, but Chaosmon retains each of the DigiCores of the Digimon before the DNA Digivolution, and maintains its form in a very incomplete state. Chaosmon is the codename for Digimon who "should not exist," and, according to the "Central Dogma" of the Digital World, are absolutely impossible singularities (bugs). Due to its extremely unstable existence, its lifespan is very brief, and it is conjectured that its lifespan was shortened as a result of running the program that eliminates the bugs released by the Digital World's managing system. This Chaosmon is believed to be one that was DNA digivolved from BanchoLeomon and Darkdramon, and the faces of each Digimon are visible on its arms. The "Ban-Tyo Blade" is equipped to its "Bancho Arm", and the "Gigastick Cannon" is equipped to its "Darkdra Arm".

The idea behind Chaosmon's creation was to create a Digimon strong enough to rival Omnimon X. Originally, the fusion was between Armageddemon and Imperialdramon Dragon Mode. Its early names were BlackOmegamon (ブラックオメガモン?) and Zexmon (ゼクスモン?).

Digimon World: Next Order
Chaosmon is close friends with ShineGreymon. After the Hero defeats Shoma Tsuzuki and the Enforcer, Chaosmon asks ShineGreymon to meet it in the Infinite Cauldron. Chaosmon planned to trap ShineGreymon in an electromagnetic barrier, and manipulate ShineGreymon into digivolving to ShineGreymon BM so it could absorb the Burst Mode energy and use it to take over the Digital World. Chaosmon would trick ShineGreymon into digivolving into its Burst Mode to break free of the barrier to supposedly stop Chaosmon dying to a dark aura due to how close they were as friends. When this happens, Chaosmon attacks ShineGreymon and absorbs some of its Burst Mode energy. Chaosmon attacks the Hero as they were in its way and Chaosmon had not planned for the Hero to come along, though decided they were a fitting enemy for it to try its new powers out on. After being defeated, Chaosmon attempts to kill itself out of the shame of losing to a human, though ShineGreymon stops Chaosmon before it can, by using its remaining energy to destroy the black aura. Defeated, Chaosmon joins the City as its decides that if it cannot defeat its enemy, it will join its enemy. Chaosmon joins the dimensional district, and when talked to gives the Hero a random chip to permanently increase one their partner Digimon's stats.
