Clarissa's Chesnaught

Clarissa's Chesnaught is a Pokemon she obtained in Kalos.

As a Wild Pokémon
Chespin is revealed to belong to a trainer who wanted a Froakie and not a Chespin. The trainer abandoned Chespin on Kalos Route 2 leading the Grass-Type's bitter opinion of humans. Later he was injured by a Fletchling which resulted in his capture by Clarissa so he can be healed. Nurse Joy healed the Intertwining Pokémon and revealed Chespin's story.

Sparks: XYZ
Chespin refused to battle against Viola because of his lost against her with his old trainer. Clarissa was okay with his decision, much to Chespin's surpise, and watched Fennekin battle and evolve in the process. He later was shown to resent Professor Scyamore after he let his fromer trainer take him. Chespin later went with Clarissa to save the Professor. Chespin evolved into Quilladin during the battle and forgave Scyamore. Quilladin was used in Clarissa's battle with Grant where he defeated both Aurorus and Tyrunt after Aromatisse failed to defeat Tyrunt. Quilladin evolved into Chesnaught in Geosenge Town.

Personality
Chesnaught has a strong distrust towards humans other than Clarissa and Nurse Joy. He is very protective over any Pokémon and especially Clarissa's Glaceon, whom reminds him of himself when he was younger.
