@Digifiend: He is referred to, far as my ears can tell, Tsu Shogun, so I'd honestly assume General Tsu to be the most appropriate translation without literally translating it and losing its double meaning.

@Woodboy:  Personally I recommend General Tsu for the page name with say a trivia thing at the bottom to explain the double meaning joke to his name, as well as the "General Pain" thing.
