Dammit, I keep saying this, but I really intend on using Dean Clobber a lot more. I like the idea of a "Thing-like" character stomping around the halls and coming down hard on the students acting out. I also like the idea of him being like the Dean in Animal House, and getting pranks pulled on him and shouting in fury while shaking a fist in the air "TEEEEAM DICKPUUUUNCH!!" But he's not necessarily an antagonist; Dean Clobber's got a level head, and unlike the wisecrack-making, fun-loving character he parodies, he's more of the no-nonsense, take-no-crap type.
While SuperDude is technically in charge of Super U., being University President, he can't be bothered with the actual running of the school. So all that seems to fall on Dean Clobber's shoulders, in addition to his role as disciplinary enforcer.
