The Chainsaw Nomu (
The Nomu has a very large, muscular build similar to the first, but with mint green skin. He wears black trousers ripped just above his kneecaps, and a brown belt. Like the previous Nomu his brain is exposed, but most of it is protected by a shiny, purple helmet with two red visors and a metal gag. The most defining feature about him is the six retractable arms that protrude from its back, each having a construction tool coming out of it.
Like the other Nomu, this one has no personality, and can only follow orders carried out by its superior.
Once the attack on the students of U.A. High School during their training camp, Chainsaw Nomu was given its orders by Dabi, which was to kill any student or staff member it comes across. It starts its attack Momo Yaoyorozu and Yosetsu Awase.
After a brief scuffle, it chases both students throughout the training camp, with Yosetsu welding a semi-unconscious Momo to his arm. Before the Nomu eviscerated them both with his weapons, he was recalled by Dabi. After retracting its Arms and started walking towards its master, Momo created a tracking device, which was then welded onto his lower back by Yosetsu. 
The Chainsaw Nomu is present at the League of Villains hideout with all of the other Nomu waiting in storage. When the Hideout Raid Team invade the premises, Mt. Lady apprehends the Chainsaw Nomu by simply holding it in her hand while her Gigantification Quirk is active.
All For One arrives and defeats Mt. Lady along with the other members of the Hideout Raid Team that are present. The fate of the Chainsaw Nomu is unknown after this.
Tool Arms: The Nomu's Quirk allows him to generate six arms from its body that end in artificial tools. Four of the arms have chainsaws, while the other two have a drill and a claw hammer.
