Darth Mixmaster

Darth Mixmaster was useless, except that he formed Devastator's head. The other Mixmaster was his bitch...sex slave apprentice. I know this is short, but it's cuz this guy did nothing anyway. If any Wikipedia dorks get on my case about this, they'll get the other Mixmaster who did more. Recently, this guy went with Darth Bay to attack Grievous and possibly discover the secret of the Sarths.
