Vincent Stegron (Earth-1600)

Vincent Stegron was an Oscorp scientist when he studied Dr. Connors' research on cross-species genetics. After finding illegally traded dinosaur embryos from the Savage Land, he thought he could take Dr. Connors' research a little further. This results in him transforming into a hybrid between a stegosaurus, a velociraptor, and a triceratops, becoming a monstrous dinosaur.
