R.O.B Robotic Operating Buddy The R.O.B was released in Japan as an accessory for the NES in 1985. It supported only two games for the NES: Stack-Up and Gyromite. Unfortunately, the accessory was short-lived and it never sold again. Unusually, R.O.B somehow appeared in Super Smash Bros Brawl, as an unlockable character and a major role in the Subspace Emissary!
