Full Cowl

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

Description
To compensate for his bodies inability to handle One For All at it's full strength, Izuku developed a way to use five percent (and later eight percent) of his Quirks power continuously. This way, he can avoid injuring himself and disregard to turn his power on and off by keeping it on. According to Izuku, this technique gives him greater maneuverability, as well as slightly enhanced strength and speed.

His enhanced mobility allows him to scale buildings with ease, clear large jumps, as well as navigate quickly through cluttered areas. He was able to find Stain and Tenya in time using this technique to run through Hosu City. His mobility even allowed him to out pace Hanta Sero during a race, someone who's Quirk also has great mobility.

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.

Variations
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): While using One For All: Full Cowl, Izuku uses a fighting style that focuses more on kicking. Izuku concentrates One for All: Full Cowl's effects in his torso and legs rather than his arms, allowing him to put out even more power due to the fact that the human leg muscles are naturally stronger than the human arm muscles, granting him more power and stability and allowing him to step away from the shackles of having to imitate All Might.
