Yeah it's possible, just a pain as the odds for shiny Beldum gift are lower than most things in the game.
Thank you mate, ye kinda easy to get shiny starter but i've been soft-reseting for beldum for like 40 minutes.
Has anyone managed to get the Beldum as a shiny yet?
Do we know for sure, the odds for the shiny mons or any extra information would be great to know.
