Chesnaught (Japanese: ブリガロン Burigaron) is a Grass/Fighting Pokémon. It evolves from Quilladin starting at level 36. It is the final form of Chespin.
Chesnaught are bipedal, mammalian Pokemon with some plant-like features. They possess a prominent domed, armor-like shell similar to that of a chestnut. The armor is pale beige in coloration with four large spines jutting out of the back. It has a trim around the edge consisting of red and green bands, with the green on the outermost edge. There is an additional spine protruding from the armor over each of Chesnaught's shoulders, which are connected by a green breastplate. Their bodies are colored similarly to the shell, and their long limbs and tail are banded with plates of armor. The top surfaces of the tail and arms are protected by green armor, and the arms have two small spines. They have three brown, clawed digits on their hands and feet. Chesnaught have fluffy white fur on their bellies and fringing their faces like a beard. They have a small, pink nose with a three-pointed patch of brown fur extending up their short snouts. They also have four pointed teeth and a plate of beige armor atop their heads, similar to a helmet.
