Just noticed after mega evolving the Christmas-themed Lopunny I received from the crates that it does not have a texture for its mega form. I'm not sure if it's just for the Lopunny, or if the Lucario from the same box also doesn't have a texture, but I think it'd be cool if the mega forms had corresponding alternate forms. Thanks for reading!
Unfortunately, this is nothing we, as a server, can do. Instead, if you want to suggest stuff like this you should suggest it to Pixelmon Generations themselves, as they're the only one with the actual ability to do this.
