Tuskmon

Tuskmon is a Champion Level Dinosaur Digimon. He appears as a fanged giant green dinosaur with spikes growing from his nose down to his tail and wears a danger symbol on each shoulder. Its most distinguishing features are its red-and-black ringed tusks which grow out of its back.

Digimon Adventure
A Tuskmon was first seen as a henchman of Myotismon. Phantomon brought him and Snimon to Aqua City where Matt and Sora were at and attacked them, punching Garurumon over a building. Kari surrendered to Phantomon, making a deal that she would go with him if Tuskmon ended his rampage and Phantomon left Sora and Matt alone. Tuskmon was later knocked out by Zudomon and was absorbed by Myotismon's bats so that he could be revived as VenomMyotismon.

Digimon Adventure 02
The Digimon Emperor had a Tuskmon under his control as he rode him to chase an Elecmon. A bunch of them were attacked by a bunch of DarkTyrannomon under the controls of the Dark Ring and a bunch of Kuwagamon under the control of the Dark Spiral. Some Tuskmon were seen on the India/China border and showed up during the final battle against MaloMyotismon.

Digimon Tamers
A Tuskmon was among the shadowed Digimon that wanted Rika to be their tamer.
