>>23560750anon please... I've been telling you for a decade now. If they already were elemental evolutions of Eevee from the beginning, the whole "making them embody the 3 elements of the three events that got them killed" makes no fucking sense.
They were Eeves.
Eevee can evolve via elemental stones of those 3 types.
What Ho-oh did was give them an overdose of said elements, making their transformation extreme.
