Robo Burner

Booster it's the up special move of R.O.B.. Is one of the best recoveries in the game. It is a booster that sends him upwards. You can also angle it to the side. But what makes it really good is that you can release the b and start it up again later. And in between you can execute moves. It lasts an incredibly long time. About 5 seconds altogether. If you just tap it he does a short hop and can attack afterwards.
