Prosucon

Prosucon is the main antagonist of Mutant Dinosaur. He is a (sort of) mutated shunosaurus.

Pre-mutate
There is not much information on what Prosucon looked like before he got mutated, although he probably didn't have the claws on his legs and the spikes on his back. The dinosaurs don't know his original colouration, but he was blue with green swirls. His eyes were black circles.

Post-mutate
After being mutated, Prosucon was changed completely. He has gained spikes on his back and claws on 2 of his legs. His blue changed into green and his green swirls turned into black ones. His eyes turned red with a black slit pupil.

First Appearance (Debut)
Prosucon is shown emerging from the trees. He chases the other dinosaurs and lures Mutant Dinosaur. He scratches Mutant Dinosaur and makes him a true mutant.
