By the way, it just occurred to me that Charizard has two mega evolutions, so why not allow multiple different custom mega evolutions?

I have a passage about that at the bottom of the first post.

[center][h3]Regarding Mega Evolutions[/h3][/center]
If there is a new Mega Evolution you want to bring in, it must first come to me, and we will talk about the details surrounding it, such as Ability and so on. They are allowed to gain new abilities, but this will be rare, as there are so many good abilities in the game already. If said Mega Evolution is already added to the RP, then you must use that version, or not at all. [i][b][color=ed1c24]X and Y Charizard and Mewtwo were a very unique case, so having more than one Mega Evolution for a Pokemon is not acceptable here.[/color][/b][/i]

Mega Evolutions can be checked in the Characters tab.

They're unique and Game Freak is basically milking them for all it's worth.

But unfortunately no one's getting held items. Only exception is mega stones.
