Looks like that alt costumes for the Miis was indeed hinting towards Meta Knight.

Glad he's back, OP or not, he's fun as hell to play.

Wow this got buried quickly...

I wonder how much they've adjusted his move-set. Surely he's not going to be the same as in Brawl.

Not sure whether to be happy or sad on this one. Happy because MetaKnight is the coolest character fro the Kirby franchise but sad because of how annoying he was in Brawl. Hope he got some adjustments in this game.

I don't mind him being back on the roster. I am curious to see how much worse he got, though. I feel like everyone thinks he's gonna get nerfed hard, but I think he'll still be one of the better players.

Good to see, but i hope they fixed him!

Only confirmed change is as follows:

"Meta Knight's Up Special Move, Shuttle Loop, changed quite a bit in this game. The glide is gone, and the attack slashes opponents twice while spinning in a large loop. This has turned into a highly technical and effective move."

Looks like Halberd will be a returning stage then?

Lets all hope they nerfed him.

It was already confirmed at E3 that old stages would be returning.

In fact I think it was the first shown off.
