Robo Burner is R.O.B.'s up special move in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U R.O.B. flies into the air using the jets under its base. Unlike other up special moves, this move can be stopped at any point and does not leave R.O.B. helpless afterward. However, the move has a limited amount of fuel, which only recharges while R.O.B. is on the ground.
Super Smash Bros. for Nintendo 3DS / Wii U introduces two customizable variants for this move. The first is Robo Rocket, which turns the move into a jump rather than flight that cannot go as high and leaves R.O.B. helpless afterward, but can damage opponents. The second is High-Speed Burner, which allows R.O.B. to fly faster but has less total fuel.
