The Mii Brawler performs an uppercut directly in front of them, dealing 5% to any opponent who they hit and knocking them upwards to the center of the stage at the highest point. The Mii Brawler will then proceed to assault them with a barrage of punches and kicks, each dealing 0.8%. The Mii Brawler then proceeds to knock them downward into the stage, dealing 15% and bouncing the opponents off the stage.
While Omega Blitz may be weak in comparison to other trapping Final Smashes such as Great Aether or Secret Ninja Attack, its damage output does make it easy to rack up damage, and its fast startup makes it a good surprise move and combo extender. However, the uppercut has a short range, and requires the Mii Brawler to remain close to opponents to connect.
