Overdrive

Overdrive, full name Gearshift: Overdrive (・), is an Ultimate Move performed by Izuku Midoriya using the Gearshift and Fa Jin Quirks.

Description
By activating Gearshift on himself, Izuku is able to propel himself at great speeds toward his opponents, in order to land powerful counterattacks. This boost in speed and power is able to be applied to existing Ultimate Moves. Fa Jin is also used to give the move greater speed.

This move is first used against "Tomura Shigaraki" during the Final War, in which he performed an Overdrive-enhanced Detroit Smash againt the villain. Soon after, Izuku uses Overdrive to perform the powerful Detroit Smash: Quintuple against "Tomura".
