In mymind, when J. Flaherty launchs an attack, he kinda makes an OK sign with his right hand, and spreads the other fingers, like forming a claw. Then, an energy ball forms, he makes a move like the pitcher at a baseball game, and he throws it. If his target was acquired enough, it's 'STRIKE THREE! TAKE A SEAT!'.
