Chewbacca vs Harvey Birdman, Attorney at Law?
Teen Girl Squad vs Teen Titans?
The Punisher vs France?
Albert Einstein vs Bambi?
This is the world of CBUB, Comic Book Universe Battles. People set up “battles” between various, mostly fictional characters and the world votes on them. Obviously, the matchups have now ranged well outside the world of comics (unless Albert Einstein has his own comic book, which would be a very sorry thing, indeed).
Looks like one of those “could easily spend a couple hours hopping from link to link” site.
(UPDATE: a very sorry thing, indeed.)
