Principal Wolverine

Principal Wolverine is a recurring villain from the classic Cartoon Network series, My Gym Partner's a Monkey. He is the bossy, loud-mouthed, domineering, and quick-to-anger substitute principal of Principal Pixiefrog. His go-to threat for misbehaving students is "Do you want me to bite you on the buttocks?" He first appeared in "Leaf of Absence". He is voiced by Chris Edgerly.

Biography
In "Leaf of Absence", Principal Pixiefrog quit his job in shame, after losing his first lawsuit, so Principal Wolverine had to step in. Wolverine ran the school like he was a drill sergeant and the students and even the other teachers were his soldiers. He lashed out at Adam and Jake for being late to school and threatened to bite their respective buttocks if they continued to be late and disobeyed his unreasonable, arbitrary rules.

Throughout the school day, Wolverine forbade avian students from flying. He ripped the nose ring off of a bull, which tore her nose open, and Wolverine claimed to have done it in the name of his "no jewelry" policy. He removed the headset of Bull Sharkowski, telling him that he's not allowed to listen to music at school. Bull assured him that his headset dispensed water into his gills, to help him breathe, but Wolverine didn't care, forcing Bull to dive into the Aquatic Wing, just to keep himself alive. Worst of all, he forced his secretary, Mrs. Warthog to actually do her work.

Adam and Jake went to Principal Pixiefrog's pad and begged him to return, but he refused. They turned to Mr. Mandrill for spiritual guidance, which gave Adam the idea to plant elephant grass on the school's front lawn. The grass blocked the students from entering the school, making for a lawsuit-worthy denial on the school's accessibility. Principal Pixiefrog saw this on the news and his lawsuit-avoiding senses kicked in, and he knew he had to spring into action.

Pixiefrog arrived on the scene and gathered together a herd of herbivores, getting them all to eat the elephant grass into oblivion. Wolverine realized that Pixiefrog was a better teacher than he was and agreed that he should go to a school, where the students are more compliant. He then took out his magical Mary Poppins umbrella and flew off to London.
