The design for Eevee and its evolutions Jolteon and Flareon were provided by Japanese graphic designer Motofumi Fujiwara, while fellow graphic designer Atsuko Nishida designed Vaporeon. Ken Sugimori, an illustrator and friend of the "Pokémon" franchise's creator, Satoshi Tajiri, provided illustrations of Eevee and its evolutions after seeing Fujiwara and Nishida's sprites. According to Fujiwara, he "wanted to create a blank slate Pokémon." Drawing upon his vague childhood memories, including an instance where he became lost in a forest and "encountered an indefiniable creature," Fujiwara would go on to create the early design for Eevee, which he likened to "a fluffy cat or dog-like creature one would see in the country."
