G0-KU is a humanoid custom modified fighting droid that has spent a great deal of time fighting in various underground fight clubs/rings. Droid, sentient, non-sentient; he's fought them in some capacity with his bare hands. How he started this career is unknown to him, it's all he's ever known. The fight organizers have relayed stories to him of his creator: a talented Verpine mechanic by the name of Bardock. From all accounts, Bardock memory wiped G0-KU and then disappeared; leaving him to wander from fight to fight. As memory wipes are typically done when a droid develops aberrant personality traits, it can logically be assumed G0-KU had developed some problematic trait and had to be reset. Why he was subsequently abandoned is not clear. As G0-KU travelled from fight to fight and experienced more of the galaxy, aspects of a personality have begun to form on top of his fighting and training programming, leading him to develop new motivations and curiosities. As such, he has requested one of the fight organizers familiar with the criminal underworld to setup a job for him so that he may explore the galaxy beyond the fight rings. The contract: protection of a Bothan trader who has gotten on the wrong side of the Hutts.

G0-KU's core motivations are still driven by his core fighting and combat programming: he seeks excellence and supremacy in hand-to-hand combat. When provided the opportunity to test himself against a strong foe, it will take a great deal to prevent him from engaging in combat. Related to this, G0-KU will not use ranged weapons, as he sees them as a dishonorable method of combat and do not provide additional experience to his hand-to-hand training. (Ambition: Expertise)
Years of organized fighting has also led G0-KU to develop a a simple moral code as it pertains to combat and approaching a situation: direct and honorable. He does not believe in stealth or taking advantage of the weak simply because they are weak. Aggression will be met in kind, but G0-KU is not prone to violent assaults of innocent or weak individuals who have not harmed him. (Philosophy: Honor)

(Contract: 10) First and foremost on G0-KU's processor is his contract to protect Kik, the Bothan trader run afoul of the Hutts on Tattooine. As his first job not inside a fighting ring, it's vital he be successful should he want to find future work of the same kind.
(Favor: 5) The fight organizer who set G0-KU up with this job was a friend of his creator. The Duros, by the name of Roche, made use of his contacts to setup this opportunity and burned through a number of favors on G0-KU's behalf. G0-KU will likely owe Roche back at some point, but how has yet to be determined.
(Family: 5) An underlying but pervasive curiosity with the whereabouts of his creator bothers G0-KU. Why was he wiped? Why was he abandoned on the fighting circuit? Answers to these questions elude G0-KU... for now.

Standing 6'5", G0-KU is a an imposing humanoid droid with plates mainly colored factory standard brown with tell-tale black and red parts from modifications. A single ocular light takes up the vast majority of his head, which is otherwise surrounded with layers of extra thick plating. His digits are not overly dexterous, possessing hands and feet with fairly simple designs. These present the most obvious site of major upgrades to G0-KU, as well as improved armor beyond his stock plating.
