>>49467151>iirc mega stones were created by dying pokemon in X and Y until ORAS made it's own explanationORAS didn't make its own explanation, ORAS used the same one. Retards just keep making their own headcanon about it.
Pic related is from ORAS. The weapon was powered by Pokemon bioenergy, (aka Infinity Energy) which after firing, radiated into the meteorites that Rayquaza happens to eat-- allowing it to Mega Evolve.
The fanon completely misinterprets the Delta Episode to the point where it's no wonder they stopped trying with decent lore after Gen 6-- retards will claim it's a retcon anyway.
