Cobblemon : Mega Trainers
by rerebleue
Cobblemon: Mega Trainers is a Fabric datapack that gives Cobblemon trainers Mega Evolution, so battles against them can drop mega stones.
What it does
The datapack includes one trainer for each Mega Evolution supported in Cobblemon, arranged in two categories of 81 trainers in total. Each trainer's team has a mega-capable Pokemon, and a trainer hands over the matching mega stone when the player defeats them. A specialist such as the Charizard X trainer drops Charizardite X on defeat. The trainers are built on top of the Cobblemon Trainers datapack, which must be installed alongside it.
The trainers are grouped in a folder by category. Deleting the folder for the megas Z-A content removes its 34 trainers and leaves everything else intact. Trainers still ship with their team, and the dialogue, level, difficulty, gimmick and reward for each one are already written into the datapack. Files are published for Fabric only, for 1.21.1, with v0.2.0 as the latest build, released in beta.
The mod is an add-on for servers and single-player worlds that already run Cobblemon. Only the server needs the datapack, so players join without installing anything, and it is released under the MIT License but is not open source. The author notes that the rest of the content is in place and that the set will be filled in a future update.
