>>29535031I don't really have any headcanons yet, I usually make them to coincide with where I catch them or important places in the games.
The only ones I know for sure so far are: 1) Wimpod and Minior being best friends, causing Minior to be a salty fuck when Wimpod evolves into a badass and Minior can't evolve. 2) Decidueye constantly using Spirit Shackle on the others in their sleep. 3) Kommo-o and Crabrawler2 having a friendly rivalry, complete with boxing matches. 4) Spider2 and Wishiwashi go on explorations in the ocean for treasure all the time.
