Cosmog The Legendary Pokémon of ultra moon

Name: Cosmog
Pokémon Ultra Moon
Type: Psychic

Description: at the start of the game you see a girl running. Her name is lilly and she will help you through out your journey, however she has the pokémon Cosmog or nebby  why is he so special you ask? Why, he is the legendary pokémon of sun and moon. It  changes into different forms compared to what game you have, eventually when you complete the game you will get it. After you complete the elite four (I think but my sis hasn't gotten it and she's the champions along with me) however I already have this pokémon along with the evolved form in this. That is all the description I can come up with I hope it was enough.
