  1. Cyrus has a Dialga in Ultra Sun and a Palkia in Ultra Moon. It really surprised me when he sent out Palkia instead of Dialga while I was playing Ultra Moon. Might want to change that.

  2. Hi I would just like to say that the Cyrus battle was mixed up with the legendary pokemon that I fought. I fought Dialga in Pokemon Ultra Sun instead of Palkia. Thanks for the guide though

  3. Hey,I battled Cyrus on Ultra moon and he was using Palkia and not Dalgia.
    I believe that information was wrong.
    Further nice walkthough guide tho
