The Legend of Zelda: Hyrule Warriors

[E-Man]

EDIT: Oh, and Zant has also been confirmed as an NPC, Bridge of Eldin is a stage, TP Link and TP Zelda are DLC and Lana and Midna fight each other at some point.

Seriously? That's very unfortunate considering how he was portrayed in the game he came from. Not only does his personality brilliantly shifts from acting serious to downright hilariously insane, but also he's no slouch at combat! Also, considering all the wild, over the top attacks the playable characters have, Zant's tendency to mimic the bosses would have been a perfect fit!
