Full Cowl

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

Description
This technique allows Izuku to activate 5%, and later 8% of One For All throughout his body, letting the power course and flow through him instead of concentrating it in one location. According to Izuku, this technique gives him greater maneuverability. Activating this technique gives him enhanced strength, speed, mobility, and agility. It also prevents him from breaking his bones when attacking and negating the need to "turn on" the power every time he needs to use it. However, 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 activating this technique, his body starts to gain red vein-like lines all over and when it is fully active, his body and eyes start to glow and electricity starts to surround his body.

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.

Trivia

 * In the subtitles and dub, the technique is known as "One For All: Full Cowling."
