Super Shadow only appears and is playable in: Shadow the Hedgehog and Sonic 06 I believe.
You have to get to the last story to become Super Shadow.
You cannot become shadow in Super Smash Bros. Brawl.
In Sonic Adventure 2: Battle you become super shadow in the final level.
The only time you can become Super Shadow in Shadow the Hedgehog is at the true final boss, at the end of "The Last Story", when you fight Devil Doom, the super form of Black Doom.
You cannot do so.
Maybe if Shadow multiplies into three he might win ,but if sonic goes super, Shadow will too ,so it wood be three super Shadows against one super sonic but if all three Shadows unite shadow wood become Eco Shadow and eliminate sonic and half of the galaxy.Shadow wins:) shadow fan Joe
