UltimateKhaosmon

UltimateKhaosmon is a Unique Digimon whose name and design are derived from "Ultimate" and the mythological Khaos. It is a Digimon born from the fusion of the four bodies of BanchoLeomon, Darkdramon, Varodurumon, and Kentaurosmon. Due to the strain from fusing four mighty powers all at once, most of the strength which had retained a balance of power collected in its arms, which took on a gigantic size as a result. Also, it is unable to store its DigiCores within its body, so the two of them manifest bare on its shoulders. Its power, which it is unable to suppress, flows from its whole body as if it was leaking out, and it's said that Rookie Digimon and below aren't even able to approach it just due to that power. UltimateKhaosmon wears a Holy Ring on its left wrist.
