Does Omega Ruby and Alpha Sapphire take place at the same time as огонь Red или Leaf Green?

Omega Ruby and Alpha Sapphire take place in a parallel universe/alternative timeline than the original Ruby and Sapphire.

Zinnia from ORAS once сказал(-а) this;
"And about the existence of another world, which we have long observed to be just like this one and yet not the same...That's right. A Hoenn region that's almost exactly like this one we live in. Filled with Покемон and people like us. A world where maybe the evolution of Покемон took a slightly different path, where Mega Evolution is unknown"

The "parallel Hoenn" she's referring to would be the Hoenn region from Ruby and Sapphire, where Mega evolution doesn't exist.

If XY is in the same timeline as the Назад games (Which it most likely is), it doesn't contradict the events in ORAS since they took place in different universes.

I don't think so.

i don't know but i think so
