I've tried asking on a few other sites and seem to get mixed responses, so thought I should try asking here:
If you defeat or run from Palkia/Dialga during the story mode, you get another chance to encounter it after defeating the Elite Four. During my playthrough of SP, I defeated Palkia with the intention of shiny hunting Palkia during the post-game second encounter rather than spending probably multiple days putting the game on hold to try and get the shiny encounter during the first encounter. However, I don't know for certain whether or not Palkia can be shiny in the second encounter or if it's just a clone of the one that you defeated/ran from during the story mode, so my question is:
Does anyone know for certain if the post-game/second encounter can be shiny if the story/first encounter was not shiny?
All of the videos that I have seen of people catching shiny Palkia/Dialga have been during the first encounter, which is why I am wondering if it is even possible for it to be shiny during the second encounter. If there is a video of someone getting it during the post-game encounter, I would love to see it!
