>>45892949My favorite theory is that the Ralts-Gardevoir line was made by Arceus or Mew (Whichever one in the Cosmology of the world creates Pokemon) as a tool for two things: 1: Guard the Planet, Pokemon, and Humanity from getting destroyed from one another through the use of future vision (Thus being able to see the passage of fate and change it), telepathy, and its later ability to conjure black holes as a last resort to end a conflict before it goes any further. 2: IF the Creator Deity decides its time to reset the world before the eventual heat death of the universe, Gardevoir's will be the one's to start that process in a mass faerie/psychic black hole ritual.
They are your guardian angels and one day your devils.
Gallade is a bit different. Its not 'natural' to this whole fate order business. Its something that's been mutated off the original design by something on the planet (Dawn Stones), but its 1st Goal of protecting the planet and its people still is at the front of its mind. Its why its so gallant and heroic. So Gallade's are just your angels! Good boys!
