The also attack lifts R.O.B. into the air slightly, allowing it to be used to aid R.O.B.'s recovery slightly. It deals minor damage (normally 4%), hits multiple times, and has decent stun and knockback. This attack can also reflect any incoming projectiles that hit the outstretched arms. The move can be bit difficult to use as a reflector, as there is bit of delay before R.O.B. starts to spin his arms, thus requiring more accurate timing than the other faster reflectors. Finally, it can be extended by rapidly tapping the Special Move button. If R.O.B. moves left or right while performing this move, his torso will also bend.
In Super Smash Bros. for Nintendo 3DS and Wii U, it now ends with an uppercut that does increased damage and knockback.
Reflector Arm is one of R.O.B.'s Side Special Moves that can be used via customizations. R.O.B. does a spin that lasts longer and with increased damage and knockback. The move can easily reflect projectiles, however, it can score only one hit.
