CobblemonStarlightFusion
CobblemonStarlightFusion is a Cobblemon add-on for 1.21.1 that lets a player fuse two Pokémon into new designs.
What it does
The add-on works through a fusion splicer: a player uses it to absorb material from a donor Pokémon, then fuses and evolves the main Pokémon to reach a new form. Each fusion is a separate splicer item. At this point only Gardevoir fusions exist, combined with several Eevee-line donors and Reshiram, and the author says more models will come in later updates.
The mod needs Cobblemon and Cobblemon: Mega Showdown. It is published for Fabric and NeoForge, with the same 1.8.0 file for 1.21.1 on both loaders, and it is not open source: it is released under All rights reserved. Fusions are a server-side feature, so the server requires the mod and players may install it to see the new forms on their client.
