Hailing from a generic sci-fi setting, Kori is a dry-dock aerospace mechanic working for Dr. Norgad (another character of mine, who I don't have art of yet); Kori's specialty is sub-lightspeed engines, but he'll rise to any task his boss gives him.
In addition to the strength of his mechanical arm, a forearm compartment houses a number of precision tools, any of which can be brought to hand with a thought whenever Kori needs one for more delicate work. The arm was given to him after he lost the original in a freak accident, and although he doesn't talk much about the event, if asked about his feelings on the matter he casually acknowledges that yes, it sucked for a bit, but what are you gonna do? This and the fact that he never misses a chance to show off the capabilities and convenience of his replacement limb have earned him the nickname "Little Tough Guy" among his fellow dock-workers, which he wears with pride.
