Zombieman

The regenerating S-Rank hero has a healing factor that allows him to bounce back from any attack, as the manga has highlighted Zombieman taking serious damage during his battle.

Chapter 99 picks up around the time of that confrontation, focusing instead on Zombieman, an incredibly durable S-Class hero capable of regeneration.

Zombieman survives Homeless Emperor's initial onslaught, but the monster blasts the hero with a beam from his finger, brutally dismembering him in the process.
