>Customisation allows you to "Cosplay" as other characters, with access to things like Roxies guitar and Lance's Cape as accessories>White hair>Pokemon follow you>Next Gen should NOT be backwards compatible, Game Freak stamps out all ties to Poke'Gen, ect.>Eviolite & Evertone are the same item>MegaEeveelution Idea;Everyone loves Eeveelutions, so this would be an obviously popular idea, but I came up with "Eeveeolite". It would act as a Megastone for every single Eeveelution, including Eevee itself.
What's more, if you chose to not evolve your Eevee, MegaEevee (Which will remain normal type), will get a Eviolite-style Defense boost ON TOP of the boosts it gets from the Mega Evolution.
Everyone has a favourite Eeveelution, so this way, everyone wins, even people who just love Eevee.
