Captain "Aarfy" Aardvark is a character in Joseph Heller's magnum opus, Catch-22. A navigator in the Army Air Corps, Aarfy is oblivious to incoming flak near his bomber, and routinely gets lost and routes planes over enemy guns. Punches thrown by the main character Yossarian are absorbed into his belly without apparent effect. The consequences of his encounter with a Roman maid, Michaela , form an emotional center of the novel.
