R.O.B. using his Final Smash: Diffusion Beam.

Diffusion Beam is R.O.B.'s Final Smash in Super Smash Bros. Brawl. When ROB gets a Smash Ball, laser beams will come out of his eyes until his time using his Brawl ends. He will be able to also use his regular attacks and move around while using this move as well. In Super Smash Bros. for Nintendo 3DS/Wii U, the attack is replaced by the attack Super Diffusion Beam.

Trophy Description

R.O.B.'s Final Smash. He emits a beam from his eyes that spreads across the spectrum and undulates in great variety as it travels. What makes this technique different is R.O.B.'s ability to move while using it. This allows him to use it in combination with his other moves to increase his Final Smash's effectiveness.
