Flo's OPM | One Punch Man Mod
by ramenmanflo
Flo's OPM | One Punch Man Mod brings Saitama's abilities and a set of playable forms from the One Punch Man series to Minecraft on Forge 1.20.1.
What it does
Players can take on the abilities of characters from the series, including combat modes with heavy punches and a set of signature attacks used to finish opponents. Becoming Boros gives access to restraining armour, several forms and their own abilities, and a number of further forms grant different stats and powers. Right-clicking during combat mode triggers a character's special ability.
The mod covers a range of characters from the series, each with a distinct play style. Black S splits into three forms that keep dividing, Zombie Man regenerates without limit, Metal Bat trades health for strength, Empty Void teleports out of dimensions by cutting through the world, and Homeless Emperor fires endless energy blasts while its body grows weaker. Playable characters, armour, biomes and foods are part of the content, and more abilities are listed as planned for future updates. The mod requires Colorful Hearts, Entity Culling, Geckolib and playerAnimator. Installation covers the server and each player's game.

How it compares
One Punch Hero is a Forge 1.20.1 mod that runs on client and server and is released under All rights reserved, not open source. One Punch Man Addonpack takes a different approach: it is available for Fabric and Forge, and either side can run it with neither needing it. Combat Man, Croaker and Mean Man are also Forge 1.20.1 mods that need both client and server, all under All rights reserved and not open source.
