Donald. And I know that wasn't an option.

*Launches you out of the airlock*

Next...

Dude. Mickey has a Keyblade.

NOT KH Mickey...

Ah... well, I guess if your meant that version the answer would be obvious.

No... Keyblade or not, Bugs wins... He can bend Physics a lot better than Mickey, after all...

Just because he can pull a giant mallet out of his back doesn't mean he's all-powerful! C'moooon!

Looney Tunes are masters of Hammerspace! HA HA HA!

Plus, Mickey has never been shown to survive a massive boulder dropping on him... Mickey will LOSE!

How do you think people summon Keyblades?! Hammerspace, yo!

Oh, come on, Sora beat Groundshaker, and Mickey is of comparable power, he could beat Bugs Bunny in a moment! Mickey is just being suppressed by the man, man, to appear more family friendlyyy! You see him on, like "Disney Christmas" or something, and then you think about he destroyed HORDES or Heartless and Nobodies!

And Bugs Bunny isn't above the use of firearms, Trickery, getting OTHERS to do his dirty work... BUGS WINS!

...When has he done this?

Firearms, I don't remember specifically, but Trickery, oh yeah. He dresses in costume to fool people all the time, and the Whole "Duck Season, Wabbit Season" Thing proves my other point...

Don't forget when he tricked the mobsters into the oven and blew them up TWICE...

...But Daffy's a moron. He's a duck.

Well, yeah, that one is good... but Mickey would... I dunno, cast Curaga or somethin'.

NOT KH MICKEY... KH IS NOT THE ANSWER TO ALL...

THIS... IS... SPAAARTAAAAA!!!*Kicks random person into spaaaartaaaahole*
