During Victory Pose hile your character is doing their victory pose, press and hold the B button and use either control pad to rotate the camera around them. 10ft away from you. If you do this correctly, you will then watch the fireball cut-scene from the intro movie. The camera should spin around the fighters who are stuck in mid-combat.
