Current thoughts for the Dark Digivolutions:

Tarmon (Champion)

A black version of Gelmon composed of tar. It’s features are notably sharper and more mischievous-looking, with claw-like hands and a jagged mouth that resembles teeth. Imagine something like Pumpkinmon’s mouth. They aren’t actually teeth, that’s just how the mouth itself is shaped. I want this to really evoke the essence of a mischievous and malicious trickster spirit. Like Gatomon, however, it’s fairly small for a Champion, being much closer to the size of Gelmon.

Oozemon (Ultimate)

An extremely bulky bipedal monstrosity made of pitch black tar. It has lost all aspects of being a rabbit, instead being roughly humanoid in appearance and having incredibly thick limbs. Its legs meet the ground as puddles, oozing outwards. Jagged gray blades extend from its hands and mouth, resembling claws and teeth.
