Fa Jin ( (はっ) (けい) Hakkei?) was the Meta Ability used by Bruce and later inherited by Izuku Midoriya,[1] before forcibly transferring it via blood transference to Tomura Shigaraki.[2]

Description[]

Fa Jin allows the user to build up kinetic energy by performing repetitive movements, emitting red colored glowing energy and store it for later use. When the user chooses to release the energy, they gain an explosive burst of speed and power. The user can use the energy with any part of their body.

The user can choose to use only some of the stored energy at a time, allowing them to achieve multiple bursts of speed and power.

Fa Jin can also be applied to other Quirks, increasing the power behind them as well as diversifying his moveset. Examples of this are Blackwhip, to create a chain that capture powerful opponents,[3] and Float, which Fa Jin can be used in combination with to boost flight speed and facilitate directional mobility.[4]

The addition of the already stockpiled energy that makes up One For All greatly increases the power of Fa Jin to the point that just 45% of One For All's power, in conjunction with energy stored up by Fa Jin and slinging with Blackwhip, is enough to reach comparable 100% levels, and without the backlash to the body.[5]

Weaknesses[]

Not much of Fa Jin is known, but it is suggested that the Quirk takes a long time to build up the kinetic energy, and if released prematurely, then the efficiency of power output may be significantly lower than expected.

Usage[]

Izuku uses this Quirk for the first time while fighting Lady Nagant. He uses Smokescreen to hinder her vision so he can jump from building to building, gathering kinetic energy before jumping out of a skyscraper and grabbing her. He then proceeds to store up even more energy, demonstrating the Quirk's synergy with One For All, to become faster than a bullet to rescue Kai Chisaki, and then uses it to execute a Faux 100 Percent: Manchester Smash to finally defeat Lady Nagant.

He would later combine Fa Jin with Float and his Air Force technique, allowing him to fly across the ocean;[4] with Blackwhip in his battle with "Tomura Shigaraki", creating Blackchain to restrain "Tomura";[3] and with Gearshift to create Overdrive, boosting his speed and power at a force described as 120% of One For All.[6]

Izuku later uses Fa Jin in combination with One For All to unleash a massive Delaware Smash that is capable of destroying the ground to halt Tomura's Decay.[7]

Ultimate Moves[]

Izuku uses Faux 100% Faux 100 Percent ( () () 100% (パーセント) Giji 100 Pāsento?): Izuku uses One For All at 45%, Blackwhip and Fa Jin to move at speeds comparable to One For All at 100%.[5]

    • Horikoshi roughly describes the concept as "all about aligning the body in such a way as to emit explosive force (jin) through minimal movement."
