Full Cowl

Full Cowl (フルカウル), full name One For All: Full Cowl (ワン・フォー・オール フルカウル), is an Ultimate Move performed by Izuku Midoriya using the One For All Quirk.

Description
During his internship with Gran Torino, Izuku developed a way to stop relying on One For All as a special move and damaging his body in the process. He learns to spread the power across his body evenly, rather than focusing his Quirk on one section at a time.

In addition to reducing the strain caused by One For All, the technique gives Izuku a much wider variety of options in combat. Since the power is spread throughout his whole body, he doesn't need to waste time re-channeling the power from one body part to another.

Full Cowl gives Izuku much greater reflexes, maneuverability, and enhanced strength. His increased mobility allows him to scale buildings with ease and clear large jumps. By studying Gran Torino and Katsuki Bakugo, Izuku learned how to propel himself through the air using the same style of movement. This allowed him to locate Tenya Ida in Hosu City by searching throughout the area very quickly. His mobility even allowed him to outpace Hanta Sero during a race, someone whose Quirk also provides great mobility. His new capabilities left his other classmates in awe.

Izuku displays increased reflexes during a sparring match with Gran Torino where he was able to read and evade his teacher's movements. Before developing Full Cowl, Izuku was completely incapable of matching Gran Torino's speed.

When Izuku activates Full Cowl, red, vein-like lines course throughout his body that coincides with the energy flowing through him. When fully active, his body and eyes start to glow with a green, bio-electric aura.

Izuku began using Full Cowl at 5% of One For All to prevent injuring himself. His overall limit increased to 8% after inventing Full Cowl - Shoot Style and fighting with Katsuki. Izuku can freely adjust the percentage of One For All at any time, but going over his limit will cause damage to his body.

Izuku has also combine Full Cowl with Tenya's Recipro Burst and Eijiro Kirishima's Hardening to break through a wall and launch themselves on Shoto Todoroki's ice ramp to fly across the battle field while rescuing Katsuki.

Izuku was able to draw out 20% of One For All without breaking any bones during his fight against Kai Chisaki. However, was only able to maintain 20% for a limited time, as it caused great strain on his body. By training with All Might, Izuku learned to draw out between 15-20% momentarily in order to utilize wind pressure for long-ranged attacks. Later on, Izuku managed to increase his limit to 10-15% without any extraneous load on his body.

By the start of the Paranormal Liberation War, Izuku improved this limit to 30% with the extraneous usage limit of 45% of his full power.
