Fan:Bronze and Cobalt/Kimeramon

Kimeramon is a Legacy Digimon that was originally created by Ken when he was the Digimon Emperor. Kimeramon is a combination of several different Champion to Ultimate Level Digimon into a single powerful Digimon. Kabuterimon's helmet, MetalGreymon's hair, Greymon's upper body, Angemon's wings, Airdramon's wings, Devimon's arms, Kuwagamon's arm, SkullGreymon's arm, Garurumon's lower body, and Monochromon's tail. Unlike Kimeramon in most other media, it is Mega level in B/C, due to the levels of the Digimon that form it's body.
