CC-5052, nicknamed Bly, was the asshole idiot douchebag jerk wanker dickhead prick asshat who killed Aayla Secura. Hey, Bly, while you're at it, why don't you give me a nice paper cut and pour lemon juice on it? Ya jerk!
Okay, okay, there was more to this jerk's life than just killing Aayla Secura. Like the time he fought Quinlan Vos, or the time he was commanding the HMS Bounty on a voyage to some Outer Rim world and his crew mutinied, setting him adrift for months, or the time he was appointed Governor of Caprioril. He later become part of the Empire as a Commander. He began to regret killing Ayala And cried about it one night with only his lieutenant, Gallie, for mental support.
Bly ran, lost and alone until the Fan Club captured him and sent him to their leader. He had Bly beat and then cut off his head. He then burned the clones corpse and threw the charred remains into a volcano. Ouch.
