**Kai Chisaki** (in Japanese: 治崎 廻 *Chisaki Kai*), also known by his villain name "**Overhaul**", is a major antagonist in the anime and manga series, *My Hero Academia*. He served as the main antagonist of the Shie Hassaikai Arc and is Eri's adoptive father and arch-nemesis. He is also a rival of the protagonist, Izuku Midoriya.

He is the leader of the Shie Hassaikai, who believes he is destined to become the next ruler of the criminal underworld and plans to destroy the current Quirk society and return the Yakuza to its former glory after the defeat of All For One.

He is voiced by Kenjiro Tsuda in the Japanese version of the anime. In the English dub, he is voiced by Kellen Goff. As a child, he was voiced by Caitlin Glass in the anime series, and Terri Doty as a child in video games.

## What Makes Him Pure Evil?

* While he did lose his entire family and was homeless before being taken in, he destroyed any tragedy he had with his actions and the fact the boss tried to raise him benevolently and guide him on a better path, yet Kai chose to use drugs and do things against the Boss's will.
* Even as a child he had violent tendencies and would kill people for disrespecting the Yakuza, causing fights with rival gangs.
* He willingly made his boss ill in order to take control over the Yakuza after he found out about what he planned to do towards Eri.
* He brutally tortured Eri (a child and his boss’s granddaughter), putting her through a childhood of abuse by cutting her arms and legs open to collect her blood cells. Once she ran out of blood he would deconstruct her (which kills her and is noted by Chisaki to be a very painful process) and then reconstruct her, which happened presumably hundreds of times. He also put constant blame on her to make Eri feel as though she deserved her punishment, calling her cursed and putting the deaths of those killed by him on Eri's hands.
	+ While he would occasionally give her gifts, it was only to manipulate her and gain her loyalty so she wouldn't run away.
* He killed off and horrifically fused the Reservoir Dogs with wreckage (although he did bring them back afterwards).
* When Eri escaped and stumbled upon Lemillion and Deku, Kai attempted to lure them back in an alley and murder them both, only stopping when Eri comes back to him.
* He will kill anyone who touches him or calls him by his first name.
* He takes in suicidal people just to use them as human shields.
* He killed Magne and blew off Mr. Compress's arm simply for touching him.
	+ And after the fact, he sarcastically apologized and proceeded to misgendered Magne, showing some level of transphobia.
	+ As revealed in the manga, although he could easily heal the scar Magne gave him, he chooses not to for no reason other than to serve as a wordless, threatening reminder both his side and the League suffered loses.
* He is brutal toward his minions, killing them without remorse if they happen to fail him or using them if he needs a human shield. Even Tomura Shigaraki was appalled by his lack of regard for his henchmen.
* One of his minions, Rappa, tried to defeat Overhaul several times, but every time, Overhaul would kill him off with his quirk and reconstruct him.
* He murdered Sir Nighteye (making him the first villain in the series to kill a major hero) and tried to kill Deku and Lemillion. He also severely injured Lemillion by impaling him with his spiked rocks and destroyed Lemillion's Quirk for a bit by shooting him with a quirk destroying bullet, even taunting him about this.
* He threatened to kill his minions unless they fought the heroes with him, leading to them all being arrested.
* He fused with Shin Nemoto and later Rikiya Katsukame against their will, allowing him to take complete control over their bodies.
* He attempted to destroy all Quirks via his Quirk-destroying bullets so that the Yakuza (a criminal organization) could rule the criminal underworld.
* Although Tomura Shigaraki severed his arm which made Chisaki unable to heal his boss from his coma, it was not played for sympathy as Chisaki deserved it due to his actions and his abuse towards Eri.
* He assisted Lady Nagant and All For One in trying to capture Deku.
* He angrily calls Deku a "diseased maggot" when he tries to speak despite Deku having saved his life moments earlier.
* When reminded of Eri after being rescued by Deku, he only focused on how he could use her powers to wake up his boss, showing no remorse for his treatment of her, something Deku calls him out on.
* While he did express some form of sentiment to the League of Villains, intending to bring out their full potential, he still was only using them for his goals and demonstrated no genuine care for them.
* Although he claims he was only acting on the best of intentions for the Yakuza, his "good intentions" are far too warped to be a genuine extremist, in which his good intentions are to crash down society so the Yakuza can take over the world with him as its head, showcasing himself to be just a simply power-hungry mobster.
* While he saw his boss as a father figure and was willing to bring the Yakuza back to power in order to pay him back his “debt” due to his boss taking him in as a child, Chisaki put his boss through a coma which lasted for a very long time and only felt sympathy for himself when he met his boss again.
