Nomu (Chainsaw)

Six arms fan out of its back on retractable mounts, each capped with a construction tool, and they are what anyone remembers. Under them sits a huge muscular frame much like the first Nomu's, though the skin here is mint green. It wears black trousers torn off above the kneecaps and a brown belt. The brain is exposed as usual, mostly shielded by a glossy purple helmet fitted with a metal gag and twin red visors.

There is nothing there. Like the rest of its kind it has no personality at all and does only what a superior tells it to do.

When the attack on the U.A. training camp begins, Dabi orders it to kill anyone from the school it encounters, and it opens by going after Momo Yaoyorozu and Yosetsu Awase. A short scuffle turns into a chase, Yosetsu hauling a half-conscious Momo along by welding her to his own arm, and it is a moment from carving through both of them when Dabi recalls it. It retracts its arms and walks back to its master with a tracking device on its lower back, created by Momo and welded on by Yosetsu as it left.

That device leads the Heroes to the League of Villains hideout, where the Chainsaw Nomu waits in storage with the rest of the stock, and Mt. Lady simply picks it up and holds it in one hand with Gigantification active. All For One then arrives and defeats her along with the other Hideout Raid Team members present, and what became of the Nomu has never been established. Its Quirk, Tool Arms, grows the six limbs with hardware in place of hands: four chainsaws, one drill, one claw hammer.
