New Super Mario Bros. 2

[Mutsukki]

But um. I don't think any game (not considering spin-offs, of course) has Mario and DK on good terms with each other. Same with Mario and Wario (Super Mario 64 DS doesn't count, there's no character interaction), so why would it be weird? While DK is not an anti-hero, he does whatever he wants. And well, Wario is an anti-hero, so he would be a good villain, I don't see why not.
