All Might starts this attack by folding his arms into an "X" shape and diving toward his target. He uses the momentum from his movement and releases extreme force through a double chop attack.
All Might first used this move against Nomu, but it was able to absorb the impact. Carolina Smash's true power was showcased in All Might's battle with Wolfram, where it obliterated the villain's iron defense. 
- Unlike other attacks Carolina Smash does not directly refer to a single state in the U.S. but rather two: North and South Carolina. Given that this attack is a two-handed chop it can be assumed that one hand represents one Carolina and the other hand represents the other.
