Nintendo has published a new trailer for Super Mario Maker.

Featured above, the new trailer shows off more of the level-making shenanigans you’d expect, however there is something new in there: a playable Bowser form. The game has already been confirmed to allow players to use amiibo to make Mystery Suit mushrooms (which can transform Mario into the Wii Fit Trainer, Link, etc).

However, the new trailer shows off the Mystery Suit mushroom turning Mario into his very own nemesis, Bowser. You’ll need the Bowser amiibo to make this happen, but you can still play as Bowser even without his amiibo, providing you download a level made by a player with Bowser in it.

Coming from this, you’ll be able to have Bowser-on-Bowser fights, which can result in some interesting scenarios.

Super Mario Maker is launching on September 10th in Japan and on September 11th in both North America and Europe.
