My Hero Academia's fourth season continues through the Shie Hassaikai arc, and at the center of it all is the newly introduced threat to the heroes, Overhaul. Not only does this new villain have a powerful yakuza organization at his command, but his bloody debut in which he killed Magne and wounded Mr. Compress with a single touch teased just how much power he had at his fingertips. But now as his quirk is being revealed, it turns out it's a lot more complicated...and a lot more deadly than initially feared.
