Jenner
He's my favorite cartoon villain ever, although others such as Ratigan are close. I just wish they had given him more screen time and development, because i think he could've had a lot more added to him. Although he was a magnetic screen presence.
He frightened the bejesus out of me as a kid, thats for sure. although he had help from The Great Owl, Nicodemus, and the Animal Testing sequences.
How does he hold up amongst other cartoon villains?
Here's a slice of pizza for ya
