Vice Principal Petrowski is the brother of Coach Petrowski and his most distinguishing feature is his toupee (which seemed to undergo dramatic changes from episodes 1-4 compared to the rest of them). He doesn't always seem to be a great friend to the students, but when one of them is successful or is willing to help, he has no problem gloating over them or handing a job to them. His relations with Tucker, Becca, Miles, and Christine are scattered and often oppositely complement each other depending on the nemesis and heroes of the particular episode. Is he a Mister Belding?, I don't think so. But, I think it's his distance from the students that he maintains that adds a little bit more realism to his character than other TV administrative figures.
