Radical Gyms & Structures [Cobblemon]
by JayOnline
Radical Gyms & Structures places naturally generating gym buildings in the world for the Kanto gym leaders, Elite Four and Champion from the Radical Cobblemon Trainers mod.
What it does
Trainers from the Radical Cobblemon Trainers mod stay in fixed buildings that generate as the world is explored. Eight Kanto gyms are included, each with its leader: Brock in Pewter, Misty in Cerulean, Lt. Surge in Vermilion, Erika in Celadon, Koga in Fuchsia, Sabrina in Saffron, Blaine in Cinnabar and Claire in Blackthorn. The Kanto league is also present, and the author plans further structures.
The package is a data pack, so it installs on a server rather than in the player's client. Command blocks must be enabled on the server for it to work. Structures for the BDSP series are not planned.
It requires Cobblemon, Radical Cobblemon Trainers, Radical Cobblemon Trainers API and CobbleFurnies. It is published for Fabric and NeoForge under the MIT License, with files for 1.21.1 only. The latest Fabric and NeoForge files, version 0.7, date from 2026-09-06.
