Our notes on Cobblemon Expanded (by Jonathan)

What sets it apart

This pack layers a large set of add-ons on Cobblemon to make it feel closer to the main Pokemon games. The project page lists towns, more than 700 trainers, Mega Evolution, Z-Moves and Terastallization, rideable Pokemon with stamina, TM and TR move teaching, breeding, GBA-style furniture and legendary encounters in structures.

Named mods include CobbleTowns, Radical Cobblemon Trainers, Mega Showdown, CobblemonRider, Fight or Flight Reborn, SimpleTMs, Cobbreeding and PokeLoot. A classic pixel grass pack gives the world a retro look. Waystones and Nature’s Compass help with travel.

Our local list for the latest build counts 124 projects. It adds Iris with Complementary Unbound for shaders, Carry On, ReplayMod and Sophisticated Backpacks.

Who it suits

Players who want a deeper Pokemon adventure than the base mod gives. The page does not tag it Challenging, but the trainer and gym content points to goals beyond catching.

Before you install

The pack is Fabric on Minecraft 1.21.1, with a 1.20.1 line also listed. The latest file in our data is 1.1.8-hotfix from June 18, 2025, and the project has not been updated since.

The page recommends at least 4096 MB of RAM. It also asks for manual steps: lowering the CobbleSounds volume by replacing files with ones from the author, and placing PokemonRideConfig.json in the root of the world folder.

The page lists no known issues apart from the sound level. The license is all rights reserved. Shaders are not mentioned on the page.

Playing with friends

Modrinth lists client and server support, and our data marks both sides as required. The mods need to match on every machine.

The version list shows a separate server pack zip attached to some releases, including the latest 1.1.8-hotfix, and its changelog says “Added server pack”. The page itself does not spell out server steps and links an author FAQ, which we did not read.

The page also promotes a BisectHosting discount using a creator code.
