Darth Scourge

"Ignore the Mynock and go straight for the Rancor."

- Master Garrus' lesson to Scourge

Darth Scourge was the Dark Lord of the Sith after Darth Caedus was killed. He was often times very sarcastic and had somewhat of a sick and twisted sense of humor. He was also unbelievably powerful (Being able to cut down the entire Sith Order at the time single handedly).
