Overhaul also has a short вЂњcool downвЂќ in which he cannot reassemble or disassemble things in that short time frame. This makes Overhaul useless in the air or where he cannot touch anything. To be able to use Overhaul, Kai must physically touch something. After Atsuhiro Sako and Tomura Shigaraki destroyed his arms, which are also his Quirk Factors, Kai is now unable to activate his Quirk. Overhaul can be restrained if Kai becomes unable to utilize his arms. This grants Kai a way to cure his and his allies' wounds during a battle, although he has noted that the deconstruction phase is very painful. When Kai decides to utilize Overhaul on a person, he can heal any injuries or ailments they once had by reconstructing them to a biologically perfect state. It's possible for a combined entity to further transform as well, as long as Kai merges it with additional objects. He performs this by holding both elements he wants to merge with each separate hand. Kai can recombine two different objects or beings into a single entity that possesses components of both subjects (including Quirks). This tactic, however, loses effectiveness in fractured terrain, where the ground is split into disconnected pieces instead of whole. Kai is able to form holes, walls, spikes, and platforms anywhere in his surroundings from a single point. When activating Overhaul on an entire area, the deconstruction and reconstruction phases both happen extremely fast. Kai is capable of deconstructing matter and reconstructing it into shapes favorable to himself and hostile to his enemies.

Kai just needs one finger to make contact with something for his Quirk to activate, with the choice of whether Overhaul should affect only one select part of his target or its entirety being left solely to Kai's wishes. This process happens instantly and is effective on living and non-living things alike. Once Kai takes a target apart, he has the option of either leaving it destroyed, restoring it to its original form or shaping it into something new. Overhaul gives the user the ability to disassemble and then reassemble matter with their bare hands.
