What Happens After Pokedex Complete

Hi Everyone . I am just asking what happens after completing the pokedex ?

I want to give try so if you tell (give a hint) It could be great .

First of all, you of course are given the shiny charm. Secondly, youll be given access to a secret fakemon on the mysterious spire (soaring location) that you can catch.

Do I want to Catch Delta Pokemon for completing the pokedex

Yes, you have to collect all the deltas if you want to complete the dex

Yes u have to collect every delta every mon and u will get shiny charm and shines will be no big deal for you, and it took me a week to do

But first I recommend finishing the game and then catching and use wiki for locations.

Yes thats looks great
