>>46252941>In his universe, Zinnia confirmed <Youtuber headcanon>Zinnia was making a callback to the originals. She and the rest of ORAS are pretty clear in their relation to Mega Evolution and Infinity Energy.
>b-b-but muh Dynamax!Eternatus has an Infinity motif, too. There's YOUR out. Since the Darkest Day didn't actually happen until the Ultimate Weapon was fired there's nothing to say that the two events weren't related. The point is that regardless of whatever timeline headcanon you come up with, ORAS confirmed that Mega Evolution is possible wherever there are Pokemon since Infinity Energy is just regular Pokemon bioenergy.
It's what Rowan was studying, it's what Team Galactic was gathering, and it's the inverse of what Eternatus deals with. The only one trying to overcomplicate it with timeline fuckery is yourself.
