Aegrus Claustrum was a Moggonite bounty hunter during the Clone Wars and a member of Cad Bane's posse before he was killed by the 1337 N00B5. Though Cad Bane loathed Aegrus, who was naive, he had hired him for his ship, the Improbus, a custom-designed starfighter armed with a diverse arsenal of weapons and boasted more features than any other craft of its class.
