One For All: Full Cowl is a technique developed and used by Izuku Midoriya.


Full Cowling mobility

Izuku's increased maneuverability

To compensate for his body's inability to handle One For All at its full strength, Izuku developed a way to use 5% (and later 8%) of his Quirk's power continuously. This way, he can avoid injuring himself and disregard the need to turn his power on and off by keeping it flowing through his body.[1][2][3] According to Izuku, this technique gives him greater maneuverability,[4] as well as slightly enhanced strength and speed.

His enhanced mobility allows him to scale buildings with ease, clear large jumps,[5][6] as well as navigate quickly through cluttered areas.[7][8] He was able to find Stain and Tenya in time using this technique to run through Hosu City.[6] His mobility even allowed him to outpace Hanta Sero during a race, someone whose Quirk also has great mobility.[7][8]

Due to the fact that the power is spread through his body evenly rather than concentrated on a single point, the overall effects are much weaker, leaving him with only slightly superhuman traits rather than the explosive power offered by 100%. When Izuku activates Full Cowl, red vein like lines course throughout his body that coincide with the energy flowing through him. When fully active, his body and eyes start to glow with a green, electric aura.


One For All: Full Cowl - Shoot Style (ワンフォーオール フルカウル シュートスタイル Wan Fō Ōru Furu Kauru Shūto Sutairu?): While using One For All: Full Cowl, Izuku uses a fighting style that focuses more on kicking.[9] Izuku concentrates One for All: Full Cowl's effects in his torso and legs rather than his arms, enabling him to use their naturally greater power to improve his striking strength and mobility by kicking his opponents, granting him more power and stability and allowing him to step away from the shackles of having to imitate All Might.

One For All: Full Cowl - 100% (ワン・フォー・オール フルカウル 100%パーセント Wan Fō Ōru Furu Kauru 100 Pāsento?): Izuku activates 100% of One For All throughout his whole body while in Full Cowl. This was first used against Chisaki to protect Eri. The power increase seemingly gives him fire like trails coming from his eyes and lighter coloured hair. He can currently only use it infinitely with no damage done to his body while in physical contact with Eri. Since Eri has the ability to rewind the state of a person's body, any damage done to Izuku's body by using One For All at 100% would continually be undone by Eri's quirk.
