Fals Beasts
Fals Beasts is a Cobblemon add-on that adds custom Pokémon-style creatures, with the MissingNo.-inspired pack expanded in this version.
What it does
The mod adds custom Pokémon-based creatures to Cobblemon, several drawing on clear inspirations while others are original concepts. It is presented as an experiment in what Pokémon could be without hard limitations, and the author describes parts of it as fun. The Fals Beasts pack adds an interpretation of Decamark named Unamark, and a MissingNo.-based line that can be obtained through a specific process, and MissingNo. can learn moves of any type through TM or tutoring.
The mod needs Cobblemon and Cobblemon: Mega Showdown to run, so both must be installed alongside it. Files are published for Fabric, Forge, NeoForge and Quilt on 1.21 and 1.21.1, with 1.0.6 as the latest build for 1.21.1. It is released under the MIT License and is not open source. The server must run it, while players may leave it out.
