Nebby (anime)

This Cosmog, nicknamed Nebby, is a -type Legendary Pokémon in the anime.

Personality
Much like Ash's Noivern when it was a Noibat, Nebby unleashes a high pitch scream when it gets upset. Nebby is also very friendly to those around it and is very playful when using Teleport on its friends with a smile on its face. It is also very picky about food and only eats star-shaped candies.

Nebby has a close bond with Ash seeing him as a parental figure and their closeness is seen when Nebby uses it's powers to teleport back to Ash on it's own. It even has a close friendship with Pikachu and Rowlet as it spends the most time with them, especially Rowlet due to both of them liking to rest in Ash's backpack.

It is also very curious when reading the thoughts of others teleporting Ash and his friends to various places wishing to see the outside world even though if it's aim is off. In the end of SM045, Nebby was revealed to be mischievous as it cries and teleports everyone at the top pillar of the Pokémon school to make them horrified on Nebby's reading from their thoughts.

Biography
Nebby first appeared in Ash's dream where he witnessed it being created by Solgaleo and Lunala. Then, on his way to the Pokémon School Ash and Pikachu see Tapu Koko who led them to Cosmog and they found it sleeping. Once Ash arrived at the Pokémon School, he showed his classmates the little Pokémon and they are amazed at the discovery. However, when it woke up, it let out a high-pitched scream whenever it cried. After calming it down, Lillie decided to name it Nebby while Ash decided to take care of it as he made a promise to Solgaleo and Lunala to take care of it.

Nebby was revealed to have learned Teleport and teleported Ash and his friends to various places. But also causes mischief in the end when it cries and teleports them into the top pillar of the Pokémon school much to their scare.
