Super Diffusion Beam

Super Diffusion Beam (, Super Diffusion Robo Beam) is 's Final Smash in Super Smash Bros. 4.

Overview
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. Like Samus's Final Smash,, the beam can be aimed at a slightly vertical angle. The attack ends with a final burst that sends opponents trapped in the large beam flying.

Origin
Super Diffusion Beam is a complete Smash original, having no equivalent in ' or ', the only two games that are compatible with R.O.B. The Beam aspect of the move is very loosely adapted from the technology used by R.O.B. and the  to communicate with games.
