Hulk vs...

The Incredible Hulk is a character who often walks a fine between good and evil, which makes his enemies all the more interesting.

Which non-superhero/supervillain character would you like to see fight against the Hulk, in a one-on-one battle?

Please, pay attention to the question - it doesn't ask which character could beat the Hulk, but which fight would you like to see.
