No. My Solgaleo is not hacked. During the postgame you can obtain a Lvl 5 Cosmog which evolves into Cosmoem and finally the cover legend of whatever game it was evolved on. I obtained the Cosmog on my Moon version then traded it to my Sun version to evolve it into Solgaleo. This also explains why they have the same ID Number. So please, don't accuse me of hacking in the future when its obvious that I'm not.
