The Shadow Master is a mysterious cloaked figure who is the true antagonist of The Wrath of Shadows, the successor to Brawl's Subspace Emissary. He doesn't appear until the final battle of the mode. Little is known about him aside from the fact that he wants to take over the Smash Universe for an unknown reason.
Much like Tabuu, the Shadow Master comes from an unknown dimension. His motives are unclear of why he wants to take over the Smash Bros. Universe. It appears that his motives may be to start a war between the residents of the universe, as he manipulates deceased family members or friends of the protagonists such as transforming himself into James McCloud, the deceased father of Fox McCloud in order to cause chaos and to mess with various characters emotions. His role as the true antagonist goes unknown throughout the story as he has most of the objectives done through villains such as Bowser, Ganondorf, Ridley, and Black Shadow. His lack of concern or care for even his lackeys and the beings under his control ends up leading to his demise after the heroes and villains team up to destroy him once and for all.
