Darth Maul

Darth Maul is a Sith Lord from the Star Wars continuum. He is heavily tattooed in red and black and carries a double-bladed red lightsaber. He appears only in The Phantom Menace and the second Clone Wars cartoon, and says very little in the first appearance; in the second, he hardly ever shuts up.

For some reason, he is a Lust Object for Mary Sues. Several such fics involve BDSM and other sorts of violence.
