Fauna Fight

Ever since he can remember, Karl E. Vorr has loved animals. However, due to his father being a zoologist, and neglecting his son in favor of his animals, this love slowly turned into hatred. After losing horribly in a fight against his father, Karl declares war: he will fight every last animal species on Earth to grow his strength and challenge his father yet again. Who will reach the top of the food chain in this nonstop battle gauntlet of feral fighters?!

This all spawned from a "Which animals could you beat in a fight?" tierlist I made. Enjoy.
