Infermon

Infermon is a Digimon whose type is unidentified. It is the Ultimate stage of Diaboromon. Its name is derived from the word inferno.

Digivolved from the 6-tentacled Chrysalimon, Infermon resembles a 6-legged ground spider with even higher speed. Both Diaboromon and Armageddemon are its Mega form, and the latter one's design is more related to Infermon, having the same 6 legs. When charging at an eneny, it withdraws its legs inside its body and launches itself at the foe, but as a result, it can only travel in a straight line.
