TK- 99 is part of the experimental line of "Hunter Killer" droids known as "Target Killers". With so many models having been in production since their inception, many modifications and adjustments have been made. Mostly being ranged assassination droids made to blend in to protocol droids, this model was a Frontline fighter. The Remnant took a liking to this but quickly swapped them for the Mechalorians. Discarded, these droids were scrapped or sold off. Sold off to a cartel, the restraining bolt was tampered with, as it was removed, he murdered most of the cartel and fled. Since then, he's been hunted by them, but continuing to find jobs and bounties to fulfill his protocol. He ran into Tzar'rae, seeing their styles as opposites, he decided to stick with her as she can kill the things he can't reach...yet.

5 Debt - the cartel wants their money back for the droid and the damages, they hunt him to get him back, one way or another. He doesn't run, just expects them to show their faces.
2 Rival - Gutrippa, first job on Sorgon, beat him up in front of the whole guild, broke his fingers, ran off humiliated.
3 - Axe to Grind - Lost to a meatbag in his final fight in the arena. He was bested and vowed to improve and initiate a rematch.
3 - reputation - won many fights in a gladiatorial arena, bested a wookie in 1 on 1 combat, did not look happy about it. Won a Butchery round.
