Full Cowl - 100% (フルカウル 100
Description
Izuku completely outclassing Overhaul with overwhelming strength and speed.
By using Full Cowl to spread 100% of his power throughout his body, Izuku's abilities are dramatically increased, granting him strength and speed that rival that of All Might, and the ability to move through mid-air using wind pressure. In this form, Izuku's hair stands up, gaining a spiky appearance, while glowing a brighter shade of green than normal, and yellow (blue in the anime) energy flows from his eyes with his electricity becoming blue instead of the usual green. His skin also adopts a reddish hue, and his pupils and irises become distorted. In the form's debut in the anime, Izuku's eyes lacked any distortion.
During the final battle against Overhaul, Izuku unknowingly went over his personal strength limit because Eri's Rewind Quirk undid the damage to his body before he ever felt any pain. This allowed Izuku to get a feel for how quickly his body gets rewound by Eri.[1] At 100%, Izuku completely outmatched Overhaul, who had fused with Rikiya Katsukame into a giant monstrous form, launching him into the sky with a single kick before beating him down with continuous punches that prevented the Villain from healing himself.[2]
Katsuki using Full Cowl - 100% against Nine, alongside Izuku.
When Katsuki temporarily received One For All, he gained the same level of physically altered feats as Izuku, albeit with a few differences: his hair became spikier, while glowing a brighter shade of yellow, and the emitted electricity was orange. While using One For All at 100%, Katsuki not only gained similarly enhanced physical strength and speed as Izuku, but his Explosion Quirk became potent enough to create large craters with standard blasts, and melt through solid rock at point-blank range. Using this technique along with Izuku, he was able to defeat Nine in his powered-up state, who ended up being completely incapacitated after the fight.[3]
During Izuku's battle against Flect Turn, he once again unleashed the power of Full Cowl - 100% to move faster than the eye can see, pounding the Villain with a barrage of punches overloading his seemingly unstoppable Reflect Quirk, and finally knocking him out with United States of World Smash.[4]
Using Overdrive, Izuku overwhelms "Tomura" at 120%.
Izuku later uses this form during the Final War in his confrontation with "Tomura" after utilizing the Second and Third's Gearshift and Fa Jin Quirks on himself. The rapidly increased speed thanks to the former and the stockpiled energy accumulated by the latter allows him to reach feats that are described as unleashing the equivalent of 120% of One For All's power, completely overwhelming "Tomura" in battle, and without inflicting damage upon his body like his previous uses of the technique.[5]
Weaknesses
When Izuku first used this technique, the major drawback was that Eri was still unable to control Rewind, and therefore, her ability to maintain Izuku's form became unstable. It is likely Izuku could have been killed had it not been for the intervention of Eraser Head.[6]
During the final battle with Nine, Izuku and Katsuki were able to access this technique unaided, despite Izuku only being able to normally handle 10-15% of One For All's power at the time. Their bodies were not blown apart; however, they still received major damage to their arms and legs during the battle. This resistance to the blowback may have been due to their exposure to Katsuma Shimano's Cell Activation Quirk, which boosts the body's physical condition.[3]
Izuku once again faced heavy damage to his arms after using the technique against Flect Turn; however, in comparison to the fight against Nine, Izuku activated it for a much shorter amount of time, and his body had reached 30-45% capability of One For All.[4]
While he was able to avoid his body sustaining any injuries in this form while using Overdrive, Gearshift's backlash resulted in Izuku being incapacitated and left vulnerable for several minutes until he recovered.[5]
