Jump Glitch is Knuckles' Up Special in Super Fighting World. In this move, Knuckles double jumps, freezes, jumps, freezes and jumps again. The first double jump deals damage, but the later jumps are just for recovery or to reach a higher platform. It is based off a glitch in Sonic Boom, where after double jumping as Knuckles, if the game is paused at the correct moment, Knuckles can jump again. The glitch has since been patched out.
