New Order

New Order, read as Nyū Ōdā, was a contact-range Emitter Quirk belonging to Cathleen Bate, America's top Pro Hero, better known as Star and Stripe. It enters the story in Chapter 330 and Episode 139. Tomura Shigaraki later tore it away from her, and after the ability destroyed itself, no one holds it any longer.

Details about it were treated as classified material by the U.S. government. All For One rated Star and Stripe the single largest obstacle between the League of Villains and control of Japan, and told his followers that seizing New Order would reduce the rest of their ambitions to paperwork. Tomura, for his part, doubted the power even deserved to be called a Quirk and wanted it badly.

The user made physical contact with something, spoke its name aloud, and imposed a rule on it. That rule could be a flat statement of fact or a conditional built on cause and effect, and it granted new properties to the target, to the surroundings, or to the user herself. Star could stack abilities onto her own body or dictate the state of an enemy's. Solid matter was not the boundary either: she set rules on the air, on laser beams, and on Quirks themselves. Tomura called it a power that rewrote what a Quirk was allowed to be, and the assessment was fair, since Star could aim New Order at New Order and change the rules governing the ability itself. Anything declared that way persisted even after the Quirk changed owners.

Its restrictions were specific and, in the end, decisive. Touch and name were both mandatory. Against anything with a sense of self, her mental picture of who the target was had to match their own, which is why Tomura's heart kept beating when she ordered it stopped: he himself could not settle on whether the answer was Tenko Shimura, the man called All For One, or Tomura Shigaraki. Objects, having no self-conception to contradict her, were far easier to bind. The results were never limitless; she could not make herself invincible, all-powerful, or the physical equal of All Might, and her fellow soldiers suspected her real ceiling was psychological, that she kept measuring herself against All Might when she genuinely had a shot at reaching him. She could also hold no more than two rules at once, so adding one meant dropping one, and no amount of clever phrasing let a rule reach a target she had not touched.

Star and Stripe kept one rule permanently running that stocked her with superhuman strength, speed, and durability, landing her in the neighborhood of a prime All Might without quite arriving. Fighting Tomura, she pulled every trace of air out of a hundred-meter stretch in front of her to force him to hold his breath, and she caught a reflected laser out of the sky. When she needed her Ultimate Moves, she shut off her standing physical rule to free a slot, which made her frailer in exchange. Her named techniques were Fist Bump to the Earth, an air construct of herself a thousand times her size that copied her motions and hit accordingly; Keraunos, in which that construct harvested the beams of her escorting X-66 jets into an enormous energy lance and drove it through her target; and the State-of-the-Art Hypersonic Intercontinental Cruise Punch, where she seized the Tiamat missiles and swung them around with the construct into a punch that detonated on a supermassive scale.

Tomura Shigaraki succeeded in stealing it, making it the first power he ever managed to steal while wielding All For One, since his earlier grab at One For All had failed with his body still unfinished. It gained him nothing. Dying, Star spent one rule slowing his Decay from finishing her, buying only moments, then quietly declared a second rule on New Order itself: that it would turn on other Quirks. The ability behaved like a virus inside him, and a Vestige of Star went through his mental landscape shredding everything in it, Tomura included, along with All For One himself and every Vestige of the Quirks he had taken. Several were destroyed outright while his body ruptured from within. New Order consumed itself in the process, leaving Tomura gravely wounded with his Quirk Factors damaged.
