It doesn’t allow its emotions to be easily seen. Earning its trust takes time. It prefers solitude.

Litten is the fire starter of gen 7. It’s kinda cute, I like its tsundere personality. I’m not too fond of its evolutions though.
In the anime, there was a wild Litten that lived with an old Stoutland, before befriending Ash and going along his journey.
