Happy J8K is an early model of the J8K series hunter droids. Programmed with a strange sense of humor designed to distract and disarm his target, there is nothing humorous about him once his blasters start firing. Like many of his model series, Happy J8K like wearing human clothing, though the oversized servos in his legs prevent most normal sized pairs of trousers.

Head is SW Pit Droid, torso, arms & hands are GI Joe Cobra Commander, and the legs are GI Joe Duke Accelerator Suit. The Jacket is from a SW Rebel Trooper.
