I did NOT expect this.
So a while back, I made this theory on Mega Gardevoir and how she achieves the "on par" requirement with her trainer to evolve further.
Of course, while it was a nice theory I was certain it was BS and that they'd never release any lore behind specific mega evolution.
Little did I know that not only was I wrong about the lore part...
But my theory was essentially CORRECT!
"The red plate in Mega Gardevoir's chest is said to be a physical manifestation of its heart. Mega Evolving enhances Gardevoir's Sp. Atk significantly."
"By opening its heart, Mega Gardevoir becomes able to use tremendous psychic power"
