No words, but they've been consistent with the shiny locks so I have no reason to doubt any difference.I assume the 3 new legendary are shiny locked, but what about the Galarian forms of the birds? I also assume shiny locked. Any word on the other legendary that you can catch? Not shiny locked like Ultra Sun/Moon?
ORAS and USUM all shared same locks:
Native legendaries shiny locked
Non-native non shiny locked
SM/USUM tecnically have the discrepancy of UBs shiny locked in SM but not in USUM, but that's about it.
Considering Dogs, Urshifu and Eternatus are shiny locked, I would expect Calyrex, Horses, Birds and the new Regis to also be, with everything else not.
