Onslaught (瞬発百裂キック, Instantaneous Hundred Rending Kicks) is one of the three side special moves usable by Mii Brawlers. When used, the Brawler charges forward with their knee out, similar to Zero Suit Samus' dash attack. If the attack hits, the Mii Brawler will launch into a series of kicks that ends with an uppercut like Captain Falcon's Raptor Boost. The move can be used in midair to recover horizontally, but will cause helplessness that way. Fortunately, the dash won't send the Brawler over the ledge if they are on the ground. If Onslaught catches an opponent in midair, the Brawler will rise up a significant distance while attacking, and may or may not drag the opponent with them.
