Now you made me want to use a Savage Reign Character for SEASON IX, and it should be obvious who if you are familiar. :P

Anyways...

If it's not Bizarro, could it be... (And yes, you can tell me if I guessed this already.)

Phoenix Ikki vs Goku?

The Boomerang vs Captain Boomerang (DC Comics)? Just wanted to make a bad pun.

Actually, A Wonderful World character should be enough to dispatch The Boomerang... Disregard my Savage Reign comment.
