Quickjaws is an unproduced toy of the LJN Toyline. This "Berserker" never appeared in any episode of the ThunderCats (original series) cartoons. The toy would have featured a Snapping jaw action whereby pressing a trigger at the back of the toy would cause its jaws to extend and bite. The jaws would then automatically return to hidden position. However, since the toy never went into production, it is difficult to know how it functioned exactly.
