Because it does warn people of disaster just like a dark kind of angel of some religions. I mainly ask this because of the white wings it grows in its mega evolution.
Well from what I heard, mega absol is supposed to look like an angel. It warns people of approaching disasters. Mega Absol is meant to be a guardian angel with the wings on its back.
Hope this helps anwser your question.
Those "wings" are just fur. If they were real wings, Mega Absol would be able to use Fly. I don't think Mega Absol is meant to look like an angel, he's meant to look like he's emitting so much power that his fur stands on end.
