Gizamon

Gizamon is a Champion Level Amphibian Digimon.

Digimon Adventure
A bunch of Gizamon were henchmen of Myotismon until his bats later absorbed them so that he can be reborn as VenomMyotismon.

Digimon 02
In the frozen part of the Digital World, the Digimon Emperor had a bunch of Gizamon build a prison there and offered a reward if they do one thing: defeat Gomamon. Unfortunately, the reward was a bunch of Dark Rings. Later on, two Gizamon were partners to two unnamed Australian Digi-Destined. A Gizamon appeared during the final battle against MaloMyotismon.

Digimon Tamers
A Gizamon was among the shadowed Digimon that wanted Rika Nonaka to tame one of them. Another one appeared in Ice Devimon's collection.
