Dan who was in TRANSCEND state moved just a single step and a sonic boom happened. Dan's movement had surpassed the speed of sound, which made it difficult for him to control his body. Even when he was creating the TRANSCEND technique, he found controlling his body in this state to be quite hard. Still, he could somehow control it to an extent that it could be used in battle. He could no longer do fancy moves, but simple moves that even a kid could do was doable.
Still, the feeling of going beyond the very limits was exhilarating. Dan was now affected by the rush of adrenaline when he uses TRANSCEND. He couldn't help himself and started laughing a bit as he got behind Leon. He was about to smack Leon to the ground, but even with his speed that surpassed the speed of sound, Leon was still able to react.
