One Punch Man transforms the player into Saitama and grants the abilities of the strongest hero: overwhelming strength, extreme speed, massive jumps, fast mining and near-complete invincibility.
The player does not lose hunger and can keep fighting without exhaustion. Powerful landings release a wind burst that launches nearby mobs away.
Punch modes
- Weak Punch: light damage and knockback for weaker enemies.
- Normal Punch: defeats most mobs in one hit; use a hit while sneaking.
- Serious Punch: maximum damage and devastating force; use a hit while jumping and sneaking.

The addon works well for fighting large groups of mobs and bosses or quickly exploring the world.
