About this Mod

What is Cosmetic Megas?

Lots of people always wanted permanent Megas and well, that would be incredibly unbalanced - so I talked to some the supporters and what y'all seem to want is to look at the mega models instead. Well the compromise I made will allow you to do just that!
With Cosmetic Megas you can equip a Pokémons Mega Stone in its cosmetic slot which will visually change it into the mega.

Addons that support Cosmetic Megas:

Lost Lore - Version 2.2.0+

  • Equip Slowbrogonite for Galarian Mega Slowbro
  • Equip Crystalline Steelixite for Crystal Mega Steelix
  • Equip Shadow Mewtwonite X for Shadow Mega Mewtwo X
  • Equip Shadow Mewtwonite Y for Shadow Mega Mewtwo Y

Your own Mega addon!?

  • If you have a Mega addon you would like to work with Cosmetic Megas hit me up!
  • Adding support for it (for addons) is as simple as making a resolver and telling me to include the code to make it work with this!

How it works:

  1. Equip your Pokémon's specific Mega Stone in its cosmetic item slot
  2. Done - it's that easy!

Notes:

  • Full support for MSD and Navas ZA Megas
  • Rayquaza requires a regular - Raw Mega Stone
  • No stat nor ability changes - it's 100% cosmetic
  • You're able to use any gimmicks and form changes but your Pokémon will always keep the mega look until you remove the stone from the cosmetic slot

How to and what version to install:

For most of you - just download the mod version. Do it manually, via the launcher or however you want
For the few of you that prefer to keep things server-sided I added a resource & datapack version - y'all will know how to install that.
