Eminem's alternate name....kinda, more like the "evil" side of Marshall. He blames Slim for everything that happens, with his family, and work, that happens that is bad. And in one of his most recent songs "When I'm Gone" he "kills" Slim.
The darker, more evil alter ego of the rapper Eminem. In his own words, "what's the difference between Eminem and Slim Shady? well, Eminem would 'fick' you, and Slim Shady would 'fick' you and your mother".
