|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. How far he rolls is determined by the punch button pressed. If he rolls into the opponent, he will hit them and rebound a small distance.
The EX Special version introduced in Street Fighter X Tekken (executed by pressing two punch buttons right before the backflip ends) has the followup roll travel much faster, grant Super Armor, and hit 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 for escape only, and to only use the forward roll 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.
