This morning it was revealed that Darkrai is going to be showing up in the arcade fighting game known as Pokken Tournament. Below is some YouTube footage of Darkrai in the game, along with some footage of Garchomp, Braixen, Shadow Mewtwo, and some various game features and locations. Take a look.
I still don't know a whole lot about this Pokken Tournament game, but Darkrai seems like a total badass in it. Of course I'd expect nothing less from one of my favorite Legendary/Mythical Pokemon.
