That explains the whole Bearstien Bears thing . <| sep |> You could also have saved right before you complete Zygarde and see what nature resulted and simply SR . Another thing that you may not actually know is if you have a Synchronizer with a certain nature in the front of your party before completing Zygarde , you will 100 % get the nature that said Synchronizer has on Zygarde as well . It is actually stated in the book , not that I would expect you to read a guide book , it isn ' t absolutely necessary . Remember to save a lot . <| sep |> I definitely really enjoyed how difficult this game was , at least compared to XY Which may be due to the fact that I turned EXP share off this time around . For me , it was the Totem Lurantis that drove me insane .
