St. Louis Smash Air Force

St. Louis Smash Air Force (セントルイス スマッシュエアフォース) is a long-range version of the St. Louis Smash Ultimate Move utilized by Izuku Midoriya using his One For All Quirk.

Description
Izuku draws out 45% of his power. He then arches his leg back and performs a strong vertical roundhouse kick, firing a large blast of compressed air.

St. Louis Smash Air Force is first used by Izuku during the mission against Humarise, where he blew away a helicopter with his air pressure.

He then later used this technique to intercept a massive wave of crumbling debris created by Tomura Shigaraki's Decay Quirk.
