With Transformation-type Final Smashes being removed entirely from Super Smash Bros. Ultimate, Rocketbarrel Barrage needed a reworking. Renaming it Hyper Rocket Barrel, Diddy Kong dons the Rocket Barrels and flies all across the stage, giving targets few places to hide. After roughly three seconds of carpet bombing, Diddy Kong homes in on a single target, colliding solidly and sometimes being an OHKO on smaller stages. Dodging Diddy's flight path is almost impossible, because it covers the entirety of most stages, including bigger ones. Additionally, the rocket barrel goes through walls, and goes for the player with the most damage taken.
