Kai Chisaki is probably better known as “Overhaul,” the (now former) leader of the Shie Hassaikai Yakuza. This villainโs arc felt like it came out of nowhere, hit readers (or viewers) where it hurts, and then faded away into nothingness. Perhaps itโs the sudden arrival followed by disappearance, but Overhaul is easily the most overlooked villain from the world of MHA. This villain hit the nail on the head when it comes to menacing, and we still canโt get over the potential this villain brought to the table.
The Villain Known as Overhaul

Overhaul is a terrifying villain who wants to obliterate quirks from the world. While some fans still love arguing about point (more on that in a moment), itโs his method that gives most people pause. He figured out a way to manufacture a quirk-erasing drug, and all he had to do was torture one child to get what he needed. If that isnโt a villainโs move, we donโt know what is.
Another thing that proves Kai Chisaki is a villain is his slightly hypocritical mentality. He hates quirks and wants to rid the world of them, so that makes it acceptable for him to use one. His quirk (Overhaul) lets him disassemble and reassemble anything he makes contact with. That includes living beings, as evidenced by what he does to Eri and his minions.
Since Overhaul was at the forefront of the Shie Hassaikai Arc, we canโt pretend that this villain didnโt get the center of attention. His villainous plan brought dozens of heroes together for the same project; thatโs not something you get to see every day, though Shigaraki makes one think otherwise.
Foil to Shigaraki

On the subject of Shigaraki, he and Overhaul couldnโt be more different, and thatโs by design. Overhaul is Shigarakiโs foil; heโs meant to stand in stark contrast to Shigarakiโs ideals. Shigaraki wants to embrace his quirks and become stronger, leaving his mark on the world. Naturally, Overhaul wants to do the exact opposite. Ironically, both want to make their goals the worldโs problem, and thatโs probably the biggest thing they have in common.
To put this into perspective, Shigaraki is seeking to obtain freedom (his) through destruction (the world). Conversely, Overhaul is striving for order through control. Two very different approaches to villainy, and that shines through in every detail and aspect of their lives. Chisaki canโt handle even the implication of something being unclean, hence his breaking out in hives while fighting.
