Compress

An Emitter Quirk that works on contact, Compress is used by Atsuhiro Sako, the villain who fights under the name Mr. Compress. It shrinks whatever sits inside a spherical zone down to a small marble while leaving it intact. The Quirk debuts in Chapter 55 and in Episode 44.

Activation runs through the hand. Atsuhiro touches his target, and the target collapses into a tiny sphere resembling a marble. The effect takes everything within a set radius of the intended object, fire and chunks of ground included, sparing only his own arm. Compressed matter weighs dramatically less, so he can carry or conceal it with ease. Release is deliberate: a wish frees one marble, a finger snap frees all of them at once, and whatever was caught alongside a target returns with it.

Against people the Quirk ends a fight instantly and hands him an easy abduction, which proves especially valuable on opponents who shrug off ordinary attacks, as Snatch did. He can catch himself in the field as well, provided he stands inside the area being compressed. Narrowing his focus to a portion of a body rather than the whole compresses only that portion and tears it free; the process seems painless, judging by his removal of one of Overhaul's arms and the mutilation he inflicted on his own lower half, since neither case appeared to hurt much.

One hard limit applies. His Quirk Factor sits in his arms, so once Overhaul took his left arm, only the right one can trigger Compress.

Atsuhiro Sako is the only user, and his background as a stage magician shapes how he fights. Stealth and agility let him seal people into marbles quietly, before a victim can alert anyone nearby, and the same trick ferries downed allies out of danger. He guards captives with illusionist habits, producing decoy marbles and shuffling them around so that anyone trying to steal from him grabs the wrong one.

His creativity widens the Quirk's range of uses. Marbles thrown toward enemies and released mid-flight block their path with restored objects; a marble holding a large rock, slipped beneath a car, launches the vehicle skyward as it expands. He can also trap a person together with an environmental hazard, which is how Snatch died inside Dabi's Blueflame. Compress chews through solid material besides, making Atsuhiro useful for breaking out of enclosed spaces and into them.
