By day, Mike Nes is a member of the Prairee Chikens. By, night, he's a novice mad scientist that is bent on turning a limited portion of the worlds population of humans into anthros and a few anthros into bulky towering monsters. Here we see Paul McGear's first successful transformation from anthro into beast. He agreed to become this creature to bring down another hulking beast from killing all the townspeople and to stop the beast from killing herself.
Mike combined the DNA of a gorilla, saber-tooth cat, and grizzly bear to Paul's dog DNA to create a giant saber-toothed beast. You can see his tooth in the top-right corner.
