One For All: Full Cowl (ワン・フォー・オール フルカウル Wan Fō Ōru Furu Kauru?, localized as: "One For All: Full Cowling") is a technique developed and used by Izuku Midoriya.


In order to stop relying on One For All at its full strength, Izuku developed a way to use 20% (previously 5% which was then improved to 8%) of his Quirk's power throughout his whole body. This also prevents Izuku from wasting time spreading One For All from one part of his body to the next, instead having every part of his body ready simultaneously.[1] According to Izuku, this technique gives him greater reflexes and maneuverability,[2] as well as enhanced strength all around.

Full Cowl's increased mobility

Izuku's increased maneuverability

Izuku first demonstrates his newfound reflexes with Gran Torino, effortlessly avoiding his attack from behind,[3] and then by dodging countless attacks from different students in the first half of the Provisional License Exam.[4]

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

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.

Despite the belief that Izuku's individual body parts become weaker by spreading One For All evenly, Izuku himself states that by spreading the 'heat' of One For All throughout himself his whole body is at his upper limit of 5% (at the time of his internship),[7] not a fraction per section.


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?, localized as: One For All: Full Cowling - Shoot Style): While using One For All: Full Cowl, Izuku uses a fighting style that focuses more on kicking.[8] 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%

One For All: Full Cowl - 100%

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?, Viz as: One For All: Full Cowling - 100 Percent): Izuku activates One For All to its fullest extent throughout in Full Cowl, granting him a tremendous boost in speed and strength that allowed him to easily overwhelm the likes of Overhaul. This was first used against Overhaul to protect Eri. Using this power in combination with Eri’s quirk makes yellow fire-like trails come out of his eyes. The power increase also brightens the color of his hair to a light green. 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.[9] In terms of function, this variation of Full Cowl is similar to how All Might regularly used One For All.
