You were running away from the Midair Stadium, as you went to a odd field where you see False Yoyo, the Subspace's sheer imitation of Yoyo, it was about to shoot Hoops with the trophie ray before you stopped and spliced it in half, completely destroying it, he looked angry and looked like he wanted to fight staring with his dead Yellow eyes.

...

the only way to turn him to a Trophie, is to defeat him...He goes into a fighting stance, What do you do?
