Onslaught

Onslaught (, Instantaneous Hundred Rending Kicks) is one of the three side special moves usable by Mii Brawlers.

In Super Smash Bros. 4


Onslaught is the 's default side special move in Smash 4. 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.

In Super Smash Bros. Ultimate


In Ultimate, the move has an altered animation, with the Mii Brawler throwing in a mixed barrage of punches and kicks, with the final blow being a backflip kick. It now does high, weight independent knockback and damage when fresh, dealing 20.5% total and being capable of KOing as early as 95%. It has also received a new mechanic: Onslaught deals increased knockback as the Mii Brawler's damage accumulates, similarly to and separate from the effects of rage, but this multiplier lowers to 1x when the move is successfully used. The maximum knockback multiplier is 1.12x, reached when the Brawler is at 150% damage or higher. It takes approximately 8 seconds until Onslaught's knockback multiplier returns to its increased value after being reset. A purple sparkle briefly appears on the Mii Brawler's shoes to signify when Onslaught's power returns to normal. When used on the ground, the penultimate strike has a meteor smash effect.

Customization
Special Move customization was added in Super Smash Bros. 4 and returns in Super Smash Bros. Ultimate for the s. These are the variations:

Trivia

 * The original in-game description of Onslaught in the move list was notably misleading, as it stated that Onslaught does more damage as more damage is taken instead of stating that it deals more knockback; Onslaught's base damage doesn't increase beyond 16% even after taking damage. The description was reworded in patch 7.0.0.
 * Onslaught’s appearance resembles a typical “Ranbu” Super Special Move as they appear in various SNK fighting games. Named after Ryo Sakazaki’s Ryuuko Ranbu, these attacks consist of a dash followed by a barrage of attacks, usually ending in a special move finisher. In the case of Onslaught, its Ultimate version strongly resembles the Houou Kyaku as performed by Kim Kaphwan, starting with a rushing knee strike and ending with a somersault kick.
