Being that I was a lucky SOB who found a shiny Bagon by accident instead of that oddly low-leveled Salamence in Sun & Moon's Route 3 today, it got me thinking of all sorts of potential horror situations. It brought me to a trial situation where if you found a shiny, you couldn't catch the darn thing...kinda like that one in Gen 3 we don't even want to think about.
But then I had to ask myself: is that even possible? Can wild Pokemon you encounter in trials even be shiny? Or have they been shiny locked? If they did, I'm sure that would be much appreciated by the players.
I think it's possible to encounter a shiny during the trials. But I would probably smash my 3ds if I did. Shinies from trials are uncatchable so yeah.
