Diffusion Beam is R.O.B.'s final smash in Super Smash Bros. Brawl. In his final smash, R.O.B. uses his eye lasers and electrocutes opponents. R.O.B. can also do the same as if he was just standing on a course, just that he has a laser beam through his eyes. Robotic Operating Buddy can also sting a big large laser that can also reflect, and can knock opponents off the stage.
