Tool Arms
CharacterThe Chainsaw Nomu fights with a body that doubles as a hardware store. Tool Arms, a conjectural label for a power the story never formally names, grows limbs with machinery fused directly into them, from spinning saw blades to a drill and a hammer.
Overview
This Quirk has no canonical title. Fans and archivists call it Tool Arms out of convenience, since the manga and anime present the ability without ever labeling it. It is a Transformation type with a close-range profile, and it belongs to the artificial creature identified only as the Chainsaw Nomu.
Mechanics
The power grows extra limbs out of the user's frame, each one carrying a piece of equipment embedded in the flesh rather than held in a hand. Chainsaws that genuinely cut have emerged this way, along with a drill and a hammer of the claw variety, and every one of them functions as the real implement would. The limbs are not permanent additions either: the Chainsaw Nomu could pull them back inside its own body once they had served their purpose.
