Gyro

Gyro is R.O.B.'s down special move in Super Smash Bros. Brawl. R.O.B. pulls out a gyromite and launches it forward. It may move differently depending on the stage and gravitational effects. R.O.B. can charge it up to make it launch faster, further and make it spin for longer, this charging technique is similar to Samus' Charge Shot. To use it once charged, the player must press the Down special attack button when they want to fire it. Once R.O.B. shoots it, the gyromite can remain on the stage for a while, depending on how long the attack was charged for. R.O.B. or other characters can pick it up and throw it again. Until a fired gyromite disappears, the player can't shoot another one. The name comes from the game Gyromite, R.O.B's first appearance and his weapon, the Gyromite.
