A character from
Dave Sims comic
Cerebus with a serious
multiple personality disorder and a
superhero complex.
Starts his career as Captain Cockroach (a parody of Captain America), then goes on during later issues to become (among others) Moonroach (Moon Knight), Sacred Super Wars Roach (Spiderman in his black dress), Punisherroach (Punisher) and Swoon (Sandman) with Elrod The Albino as his sidekick Snuff (Death).
In short, almost all episodes where The Cockroach appears are hilarious. Sim knows the business and he certainly knows how to make fun of the superhero industry.
