>>42582828wasn't he just given the order of making an antagonistic version of an existing legendary for the new game, which obviously already focused on shadow pokemon since colosseum came first? sure he probably could've changed more but I feel like picking a pure white legendary to make an evil shadow version of is a good, inoffensive way to go about it.
plus shiny rayquaza is already black and was probably the best option besides maybe mewtwo which had already been evil-ified before (and its funny cause they made shadow mewtwo for pokken, too)
