New Hampshire Smash is an Ultimate Move performed by All Might and Deku using the One For All Quirk.
Description#
While airborne, the user throws a powerful punch to propel themselves backwards through the air towards their target at high speeds. This technique weaponizes the user's mass and body weight, as they blast themselves into their opponent as an attack.
All Might is first shown using this technique against Izuku during the First Term Final Exam.[1]
Deku used this technique when he launched a barrage of smashes during his second fight with Dark Might.[2]
