Nightmare Wizard--the evil villain who brought nightmares to Kirby's Dream Land--will now be able to use his powers to help players defeat opponents as an assist trophy in the new Super Smash Bros. for Wii U and 3DS.

On Monday morning, Masahiro Sakurai, the game's director, took to the Nintendo Miiverse to announce the addition of the terrifying Kirby boss and to elaborate on his ability to plunge the entire arena into darkness for a brief period. During the blackout, players (and even CPUs) are more susceptible to falling mid-battle, but a truly skilled player will most certainly be able to use Nightmare Wizard's power to his or her advantage. Here's what Sakurai had to say about the new addition:

Nightmare Wizard appears as an Assist Trophy! He will engulf the stage in darkness, and fighters will need to brawl blindly for a while. Look out for the effect before it goes dark, and play it to your advantage. Blinding and reversal effects even make the computer players mess up.

Super Smash Bros. will be released on 3DS in North America on October 3rd. An official release date for the Wii U version has not yet been confirmed.
