Dorimon

Dorimon is a Lesser Digimon and a carrier of the X Antibody. It can run very quickly if it is going straight. It is often running wild because it hates to be domesticated, and it is dangerous because it will recklessly charge and perform a ramming attack if approached. Its ears have grown sharp and hard, and because they also act as horns, there is some small damage from its ramming attacks. However, it can't turn when going at speed.[4]
