Transmission

Transmission (トランスミッション) is an Ultimate Move performed by Izuku Midoriya using the Gearshift Quirk.

Description
Izuku rushes toward his opponent and delivers several punches, with each successive punch increasing the speed of Gearshift, before sending his opponent flying. The increase in speed is labelled as "gears", with the gears being First Gear, the base speed that is activated upon using Transmission, Second Gear, Third Gear, and Top Gear, the final and fastest speed. Each punch of Tranmission is so fast, that the sound barrier is broken numerous times, causing the punch to be seen before it is heard.

This Ultimate Move is first used against "Tomura Shigaraki" during the Final War.

Trivia

 * Izuku shifting this Ultimate Move like gears may be a reference to One Piece's character Monkey D. Luffy's abilities to shift gears thanks to the Devil Fruit.
