Rolling

Rolling is a maneuver in the Super Smash Bros. series and Super Smash Flash 2 that moves the character left or right and renders them invincible for a short period of time. It is performed by pressing the control stick left or right while holding a shield button. Rolling was not possible in Super Smash Flash, as shielding also was not.

Characters gain invincibility frames when they roll which makes it a safe option. Currently the majority of characters have the same amount of frames that the roll lasts. However, the speed of the rolls vary from character to character. The animation of the roll vary for each character also. Some characters will just roll, some will perform acrobatics and others have rolls that pay homage to their home series. will curl up into her morph ball, will encase himself in his egg,  will perform Shunpō, and  will perform the Body Replacement Technique.

Characters when rolling will always end up facing the opposite direction they rolled into. That is, characters that roll backwards will remain facing the same way, while characters that roll forwards will turn around. This allows rolling through a character to then execute attacks with more ease, but can disrupt them when trying to dodge projectiles and approach the opponent at the same time. Interestingly, a character cannot roll off the stage if a player performs this move near an edge; the character will instead perform the remainder of the rolling animation in a stationary location right next to the ledge.
