Alpha-66

Alpha-class ARC trooper A-66, nicknamed Muzzle was a veteran of the Clone Wars.

Bio
After the Clone Wars, all surviving ARCs, save for the Nulls, whose fate as of now is unknown, were offered retirement. Some ARCs did so, and lived out a quiet life for the rest of their days, some trained their successors, the stormtroopers, some defected to the Rebel Alliance, and some went rogue, following in their progenitor's footsteps by becoming bounty hunters and assassins.

Alpha-66, nicknamed Muzzle, selected the latter option, founding the Aurodium Sword mercenary group, taking jobs for criminals and Imperial allies. Muzzle's erstwhile Imperial comrades were rather suspicious of his friendship with Wookies, such as fellow bounty hunter Snoova.

Physical appearance
Muzzle, like all clones, was the spitting image of Jango Fett, though by now his once jet-black hair was now growing white, and one other distinguishing trait: a massive X-shaped scar across his forehead. Muzzle wore a repainted grey and red set of various pieces of clone armor: a Katarn-armor chestplate, standard trooper armor everywhere else, and an ARC's pauldron and kama.
