Back on Nebulos, Nightstick was a master criminal. For some reason, he gave that up to undergo binary-bonding to Cyclonus. The loyal and honorable Decepticon warrior often finds himself at odds with the very dishonorable Nightstick and generally considers him an irritating pest. Nightstick transforms into a black beam gun that fires a corrosive beam of blinding darkness (and no, that doesn't make a lot of sense).
