Jackknife is a mini-con in Universes: ut Jackknife is a member of the Aerial Extermination Mini-Con Team, and a personal attendant to Nemesis Prime. Like an inordinately vicious magpie, he'll swipe anything that catches his eye, and he doesn't care if he has to beat the owner to an Energon-spewing pulp to get it. This puts him at odds with the stealthy Maverick, but Jackknife either doesn't notice or care how his teammate feels, so long as he gets his swag.
