Nintendo has revealed a surprise new stage for Super Smash Bros. for Wii U and 3DS based on the just-released Super Mario Maker.

The brand new stage leverages the endless creative potential seen in Super Mario Maker by forming the stage before your very eyes at the start of the fight. The layout will change every time you play.

The 'hand' from Super Mario Maker will even repair blocks which are destroyed in the fighting.

Check out the stage in action below.

The Super Mario Maker stage will be available to purchase and download from September 30th.
