The upcoming DLC for Pokémon Legends: Z-A introduces Mega Lucario Z, a new type of Mega Evolution. Obviously, it's only a matter of time before Charizard gets one, but the list shouldn't stop there. If I had my choice, Flygon would get both a Mega and a Z form. It's been waiting long enough to get some love.

This is definitely a pipe dream at this point, but I'm still dreaming of Megas for all the Eeveelutions and meanwhile they're putting out alternate Megas for Pokemon that already have one lol. Otherwise, I think it'd be cool if the original starters got Z forms.
