It's totaly fake Nintendo would never create a game that stupid, the characters were customized and the graphics a long with the movements were terrible. Funny though
You're not serious are you? It's faker than a Pokemon Rainbow Topaz for GBC that comes boxed with a see-through Lt. Surges' Dark Rocket's Medicham* EX d that's actually a sticker.
Someone just spent a lot of time customizing characters and then put the video together.
