|~ Dr. Simon Fessenden to the player before mutate into the final dinosaur form.|
Fessenden is the leader of the Black Merchants, a group of mercenaries who capture and kill dinosaurs for him. It is eventually revealed that Fessenden is creating reptile-human hybrids and is about to spread them over the world so he can create what he believes will be a more improved and better planet. Jack Tenrec and his friends realize that he is insane and must be stopped. They head to the doctor's laboratory which is underground. Eventually, they find Fessenden and prepare to fight him. In the first part of the final battle he transforms himself into a mutant dinosaur hybrid, but is defeated easily. However, he then mutates again, this time into a hideous reptilian creature with two dinosaur heads that breathe fire and his own original head and arms in its chest. After a long and difficult battle, Fessenden is defeated again, this time once for all. Just before dying, he says his last words, and then falls lifeless, but not without triggering his self-destruction device which causes the lab to explode. However, Jack and his friends manage to escape before it's too late.
