>>40975999You got something confused here.
First mega evolution in Kalos was Lucario. First ever mega evolution was Rayquaza.
Mega evolution only happens because Az fired his weapon into space creating megastones. XY and ORAS are part of the same timeline.
>>40976453ORAS only retconned that Mega's are Kalos exclusive but it's not really a retcon since it's just Professor Skymore thinking so.
In Oras there exist two worlds one where the weapon exist XY, Oras, SM where mega evolution is a thing and one without the weapons. Game boy games till DS.
