Mewtwo will be available as a free character in Super Smash Bros. if you own the WiiU and 3DS versions
Now Mewtwo
If you register both the WiiU and 3DS versions of Super Smash Bros. during a special promotional period, you'll be able to download Mewtwo as a free character next year.
And as everyone knows, Mewtwo is a Pokémon that looks a bit like a really annoyed cat that can kill you with its brain.
So there you go. We're not sure when the promotional period actually is, which is a bit rubbish, but we'll let you know when we hear.
