Diffusion Beam

R.O.B. can still use items while Diffusion Beam is in effect.

The Diffusion Beam is R.O.B.'s Final Smash. It is basically his Standard Special Move with some twists. R.O.B. shoots short-ranged whirling lasers out of his eyes, followed by some hard-hitting short lasers. Similar to the Superspicy Curry. R.O.B. can move freely during the Final Smash. Being in the general area in front of R.O.B. causes damage that rises at a 2% damage rate and as long as R.O.B. is in front of an enemy, he will continue doing damage. The short-ranged laser has decent knockback. However, as the move has such a short range, it is one of the most easily avoided Final Smashes. However, it lasts for a decent time and renders R.O.B. invincible for the duration, resulting in somewhat of a chaos as he chases opponents around the stage, trying to catch them in the deadly vortex of his eye beams. He can also use his entire moveset (minus a few special moves) during the Final Smash.

Trivia

• For some strange reason, this Final Smash is the only one that was not described on the DOJO.
• R.O.B. is the only character besides Jigglypuff who can benefit from the Bridge of Eldin Final Smash glitch, giving him a never ending Diffusion Beam (Jigglypuff's makes it remain huge). Although, in order to make this happen, the player must have R.O.B. get caught in the re-materialization of the Bridge during the close-up animation that starts the beam. If the player does it at any other time, R.O.B. will merely take damage, and waste the time of the Final Smash. Strangely, if you use it right as the bridge becomes solid, R.O.B. will be invincible and will make the noise of the Diffusion Beam, although he is not using it.
• If R.O.B. uses his side taunt during his final smash, the Diffusion Beam will travel in an arc over him as he moves his head.
• Even though R.O.B. can use items during this state, he cannot use items that require the character to "pass through" them. (i.e. Starman)
• Because of the way the beam works, it can become possible to cause damage with his taunts because they follow the direction his head moves in. Luigi and Snake share this quality, albeit being more convenient for them.
