Role in the Movie
Kozak and the whole corporation were being charged because of unauthorized mutations with animal genes. He kidnapped a dog from Tibet who is believed to be 300 years old, trying to use his genes to develop a potion for immortality. His many attempts to capture "Shaggy" (the dog's name given by the Douglas family) resulted in the "accidental" capture of Dave Douglas, that was bitten by Shaggy and became a dog himself. Dave bites Kozak while in capture, and runs to the courthouse along with his family to get Kozak in the act. He is finally defeated when Dave trows him a nightstick like a common stick, alerting his dog senses to get it, thus causing him to grow a tail. Kozak is immeadiatly arrested soon after.
