Nomu (U.S.J.)

Scars cover the muscle of this towering black humanoid, which stands taller than All Might himself. Nothing caps its skull: the brain sits open at the top with oversized eyes ringed around it, and the jaw below narrows into a beak crowded with sharp teeth. Its clothing amounts to beige trousers and metal knee guards shaped to resemble skulls, leaving the torso and feet bare. The man it was made from looked ordinary by comparison, marked only by thick lips and hair of a light olive green.

The experiments that reshaped its body left nothing behind capable of speech or of independent thought. What remains carries out instructions and nothing else, which is why Tomura Shigaraki's orders are obeyed at once and without question. Against an opponent it is savage and grants no quarter, wrecking Eraser Head and caving in part of All Might's ribcage. Take away the voice giving orders, though, and the creature simply stops. Captured with no villain nearby to direct it, it went along quietly and never resisted arrest.

Before the alterations it was a petty thug. DNA drawn from four separate people was injected into its body under circumstances that remain unrecorded, stacking several Quirks into one frame and finishing the process as an artificial human. Its unfinished body first appears inside a stasis chamber in one of Kyudai Garaki's laboratories, months after The Crawler's last clash with Number 6 in Naruhata. Struck by how much an ordinary citizen had managed, All For One resolves to answer with something capable of driving All Might himself onto his knees, and credits Number 6's actions with the idea.

Kurogiri warps the creature into the Unforeseen Simulation Joint alongside the rest of the villains. It flattens Eraser Head, then blocks a One For All punch from Izuku Midoriya without taking a scratch. Shock Absorption blunts All Might's Carolina Smash, and a backdrop slam is dodged through one of Kurogiri's gates, after which the Nomu seizes hold of All Might until Shoto Todoroki freezes half of it solid. Ordered to deal with Katsuki Bakugo and recover Kurogiri, it tears loose, loses its frozen half, and grows the limbs back within seconds. The two then trade blows until All Might pushes past his own hundred percent and drives it out of the facility, four hundred metres into a forest, where the authorities collect it without a struggle. Tomura had noted that the absorption has a ceiling and that slow lacerations could get through it; All Might, no longer in his prime, needed roughly three hundred punches to finish work he reckoned five would once have done.

In custody it sits in a straitjacket, answering nothing the Police Force puts to it, so they run a DNA analysis instead. A year on, it and every Nomu seized since are moved into Central Hospital, where restorative research begins in the hope of understanding the process well enough to pull Oboro Shirakumo back out of Kurogiri.
