|All appearances||(+ to roll forwards)|
Executed by pressing all three punches, Rolento performs a simple backflip, much like one of Vega's. If punch is pressed while Rolento is about to finish the backflip, he will tuck into a ball and roll forward, not unlike a ground-travelling version of Blanka's Rolling Attack.
The followup distance rolled forwards is determined by the punch button pressed. If he rolls into the opponent, he will hit them and rebound a small distance. In Ultra Street Fighter IV, the followup roll has armor breaking properties.
The EX Special version introduced in Street Fighter X Tekken (executed by pressing two punch buttons right before the backflip ends) rolls much faster, grants Super Armor and hits up to four times, dealing more than double the damage.
The rebound occurs even if the hit is blocked, making the attack somewhat safe on block. However, because the backflip may alert the opponent to the possibility of the attack, Rolento is often likely to be hit out of the roll.
A recommended tactic is to mostly use the backflip solely for escape, and the forward roll only when opportunities present themselves, such as when the opponent throws a projectile while Rolento is backflipping.
The attack, like many in Rolento's repertoire, is named for the Mekong River Delta in Vietnam, suggesting that Rolento may be a veteran of that war.
