One Piece Bosses - Mine Piece X Mine Mine no Mi Addon
by Iandrex1
With One Piece Bosses installed, Mine Piece bosses spawn across the islands of One Piece World Like, so exploring the Grand Line brings encounters with famous enemies.
What it does
The addon places iconic Mine Piece bosses into the world generation of One Piece World Like. Bosses appear naturally as players travel between islands, which ties boss progression to exploration and sailing rather than to a separate arena or command. Encounters follow the Mine Piece game mechanics, so the existing combat and drop systems keep working as they do in that mod.
It requires Mine Mine no Mi, Mine Piece and One Piece World Like - Mine mine no mi, and HakminePiece is optional. The addon is compatible with the island generation of Red Line, Calm Belts and Reverse Mountain. It is a Forge mod for 1.20.1 only, first published 2026-06-09 and last updated 2026-09-04, and the client needs it while the server may leave it out. The code is not open source; it is released under All rights reserved.
Key features
Bosses on the islands
Iconic Mine Piece bosses generate across the One Piece World Like islands and wait for players to find them.
Progression by travel
Stronger enemies appear farther along the route, so the boss challenge grows with the distance a player covers.
Mine Piece mechanics kept
Bosses use the existing Mine Piece game mechanics, so the addon adds encounters without replacing that gameplay.
Lightweight install
The addon is added alongside the required mods without changing their setup or world type.

How it compares
HakminePiece is a Forge client and server mod for 1.20.1 under All rights reserved, and it is not open source. Mine Piece NPC Spawn Control is also a Forge client and server mod under All rights reserved, with files for 1.20.1 – 1.20.6, so it covers a wider version range than One Piece Bosses. Alternate End is a Forge client and server mod for 1.20.1 released under the MIT License, so its code differs in license from this addon.
