Well since Golden Boy had taken care of the assault rifle guy, MMM immediately used that chance to throw his two shiruken at the boom box. If he could get rid of the weapon before the guy got a chance to use it, that would be most advantageous. Just before impact with the boombox, MMM claps his hands to release his quirk.<br/><br/>After Golden Boy ordered him and Taffy Twister to make sure that the other two did not escape. He lightened himself with his quirk and then ran as quickly as he could around to behind the other two villains. He still had no idea what their quirks were and since all the civilians had fled, there was no immediate danger that would force him to be reckless. Plus this also allowed him to cut down on their avenues of escape.
