17. Darth Malek
The uber-creepy, jawless Darth Malek was Darth Revan’s right hand man, and for decades, the two were one of the most reviled and feared duos in the galaxy (even more than Hall & Oates!). Malek was just a lil’ more evil, though, because he ended up double crossing his brother in arms. Hey, maybe with that missing jaw, he felt he had something to compensate for.
