Template:Infobox Final Smash SSB4R.O.B.'s Final Smash in Super Smash Bros. 4 does not have a currently known official name, though it is referred to as Super Diffusion Beam in Prima's guide for Super Smash Bros. for Nintendo 3DS. When activated, R.O.B. transforms into a laser cannon and fires an intense beam of energy at the opponent. The attack starts off as a large beam that can trap opponents in place. The large beam then splits into four smaller ones, each at a different angle. The attack ends with a final burst that sends opponents trapped in the large beam flying.
