Overhaul (Quirk)

Overhaul (オーバーホール) is a Quirk used by Kai Chisaki.

Description
Overhaul gives Kai the ability to disassemble and then reassemble anything he touches with his bare hands.

Once Kai takes a target apart, he has the options of either leaving it destroyed, restoring it to its original form or shaping it into something new. This process happens instantly and affects living and non-living things alike. Overhaul takes just one contact with Kaifinger to activate, with the choice of whether the Quirk should affect only one select part or the entirety of his target being left solely to Kai's wishes.

When Kai decides to Overhaul a person, he can heal any injuries or ailments they once had by reconstructing them to a biologically perfect state. Kai has used this ability on himself and noted that the deconstruction phase is very painful.

Kai can recombine two different objects or beings into a single entity that possesses components of both subjects (including Quirks). He performs this by holding both elements he wants to combine with each separate hand.

Kai is capable of deconstructing matter and reconstructing it into shapes favorable to himself and hostile to his enemies. When overhauling an entire area, the deconstruction and reconstruction phases both happen extremely fast. Kai is able to form holes, walls, spikes, and platforms anywhere in his surroundings from a single point.

Usage
Kai's main usage of Overhaul outside of battle was obtaining DNA samples from Eri, which was realized by destroying her body, collecting some of her remains and reassembling her back to life. Because Eri had access to a Rewind Quirk, Kai was able to experiment on her blood, transforming it into an ingredient for a special drug that could reverse a target's Quirk Factor, turning them Quirkless.

Yakuza's traditionally avoid being convicted for crimes by leaving their trail clean. Chisaki cleaned up his crimes by disassembling his targets first, taking what he needed and then restore them to perfect condition. He also uses this same tactic to recruit members to his organization.

In battle, Chisaki focuses on quickly dissembling his targets to kill them or reshaping his terrain into a barrage of spikes. He can reshape the ground to maneuver himself around and block incoming attacks. The variation of his attacks is great because Chisaki can reshape the ground into any dangerous shape best suited to pierce his foes. This also makes him a threat from both close and long range.

After overhauling himself and Shin Nemoto, Kai Chisaki revamped his own body into a monstrous form, who had access to both this Quirk as well as Shin's. This form granted Chisaki increased power, speed and an extra set of arms for him to activate his Quirk through. He would repeat this tactic with Rikiya Katsukame, taking advantage of his grown body to increase his abilities even further.

As Kai suffers from mysophobia, the resulting gore that's sometimes left by his Quirk's deconstructing process might trigger a nervous reaction from him if it ends up spilling on his body. His Quirk can be restrained if he becomes unable to utilize his arms.
