Rollout is the neutral special move of Jigglypuff in the Super Smash Bros. series starting with Super Smash Bros. Melee, replacing Pound, which is now its side special move, in Super Smash Bros. and based upon the move in the Pokémon series. By holding down the special attack button, Jigglypuff charges the move by rolling in place, and starts to roll forward in the direction it was facing before charging, the roll lasting as long as the move was charged. The move deals the most damage and knockback at maximum charge, while it does not have any effect on opponents at minimum charge. The player can also turn around while rolling. If Jigglypuff hits an opponent while rolling, it automatically stops, bouncing into the air before returning to its normal position.
Starting with Super Smash Bros. Brawl, the move has a "super charge" which does not increase its damage output but increases its distance both on the ground and in the air. The player can also angle the roll back when used in the air in Super Smash Bros. Brawl, and it also no longer leaves Jigglypuff helpless when used in the air.
In Super Smash Bros. for Nintendo 3DS / Wii U, this move has two custom variants that can be unlocked. The first custom is Relentless Rollout, which charges faster, moves faster, and deals multiple hits, never stopping after hitting an opponent, though it cannot be controlled as easily. The second is Raging Rollout, which is faster and deals more damage, but takes longer to charge and cannot be turned around.
