Easy win strategy
At the start mash left and right arrows to K.O. him, dont bother trying to push left and right continuously when he's down because it wont work. The knights appear, so hold A and S until it switches to Red (nothing) and mash Left and right arrows.
Then you need to do some quick reactions, preforming moves to hit Tom. Do the right key or nothing will happen. From there its normal brawling.
