How do you unlock tabuu in ssbb?
Tabuu is a boss and you cannot “unlock” it as a playable character. However, to unlock it as a boss, you have to get to the final stage of the Subspace Emissary, The Great Maze. You must then complete it by defeating all of the fake characters and bosses that are scattered around it. You then proceed to aquire Sonic and battle Tabuu. After this, you can fight Tabuu again by either playing The Great Maze again or playing Boss Battles mode.
