Anyone think they're gonna retcon Greninjash as Mega-Greninja due to it's popularity?
Wouldn't be hard to I imagine.
"Professor, how was Ash able to achieve mega evolution without a Keystone and Megastone?"
"My theory is that Ash's bond and synchronization with Greninja is so great that they actually managed to achieve mega evolution without the use of a Mega-Stone."
"But why does Ash feel Greninja's pain when it Mega-Evolves?"
"That's probably a drawback of the 'Stoneless Mega-Evolution'"
"Stoneless Mega-Evolution?"
"Yes. As you can see it's more powerful than normal Mega-Evolution but it becomes a risk to the trainer whenever it's used."
"So having a Mega-Stone limits the synchronization between the trainer and Pokémon?"
"Precisely, the Pokémon still gets a gigantic boost in power but the trainers life isn't put in danger when it's used."
Done, retconned and gay.
The Greninjash lovers get to use it in their games and Ash now has a reason to receive a Keystone.
And the 'limiter' thing works in game as well since Mega-Evolution adds exactly 100 BST iirc.
