Tbh, I really only have two requests for Fennekin, keep it quadrupedal and please not Fire/Fighting type, lol. Idc if it’s Fire/Psychic (my preferred choice), Fire/Ghost, Fire/Dark, Fire/Ground or pure Fire as long as my two requests are met, lol. I also love the idea of the ear fur (a feature that scares me when it comes to it’s evolutions) will turn into fire, playing off of Fennec foxes dispersing heat from their ears. Hopefully kitsunes (not kyuubi) will play a role in it’s evolutions inspiration.
For Froakie, this one’s a hard one, I could see pure Water, Water/Fighting, Water/Electric, Water/Ice, Water/Psychic or Water/Flying from him. I also could see his evolutions going the Frog Prince route, Superhero route, Benjamin Franklin route, Thor route, Frog on floating cloud route, Gentlemanly toad route, Toad sage route, Wizard route, Sumo route or the Journey to the West Monk route and those things on his face could be a nose, “spectacles” or a budding mustache, I honestly have no clue where he’s going.
As for Chespin, I see his inspiration coming from (on the fauna side) Hedgehogs, Chipmunks, Moles, Gophers, Groundhogs, Woodchucks, Ferrets, etc… and his flora side from the horse chesnut. As for typing I could see Grass/Dark, Grass/Fighting, pure Grass, Grass/Steel or Grass/Ground. I see spikes being emphasized in his design and maybe even having Badgers, Wolverines, Pangolin or Armadillos contribute into his evolutions, maybe a kind of armor with that chestnut shell, he could be the Grass type Typhlosion.
