Transforming Arms

Transforming Arms is a Transformation Quirk rated at mid-range. Its original owner is never identified, since All For One stole it and eventually passed it on to Hood. The ability debuts in Chapter 186 and Episode 87, and picks up its name two chapters later.

The user's arms stop behaving like fixed limbs. They can stretch far past their normal span, delivering rubbery strikes from well outside conventional reach, and they can swell in size so a fist lands with far more mass behind it. The arms can also divide into multiple strands, wrapping around a target from several angles so a barrage arrives at once instead of a single blow.

The catch is compatibility. A fighter whose instincts do not suit shape-shifting gains little from it. Hood built his style on close-quarters martial arts, and the Quirk pulled against that habit: winding up a stretched attack introduced a slight delay, and O'Clock spotted the lag during their fight and exploited it.

Hood is the ability's showcase. Before his High-End conversion, the Underground Masquerade pitted him against Rumi Usagiyama, Kendo Rappa, and O'Clock, a brawl in which he extended his arms and legs to snatch at opponents or drag them out of position, enlarging his fists for heavier hits, and grabbing nearby objects to swing as improvised weapons. All For One had only recently gifted him the power, expecting it to round out his arsenal, and openly regretted how poorly it fit the way Hood liked to fight.

Once he was rebuilt into a High-End Nomu, the power found a use its original owner may never have imagined. He reshapes his arms into wings and pairs them with his Shoulder-Mounted Jets, letting the boosters drive him through the air at high speed. All For One himself is listed as a former holder before the transfer.
