Sugimori: "Then we do another division of roles for the evolved forms. This time around — because the Unova region has a racially diverse human population — we decided to make the starter Pokémon's evolutions symbolize the cultures of Japan, the West, and China. Snivy's final evolution, Serperior, was designed with the concept of a European knight in mind, kind of like Lady Oscar from The Rose of Versailles. Tepig's final evolution, Emboar, stands up on two legs and becomes humanoid, so we imagined him as Zhang Fei from the Chinese Romance of the Three Kingdoms. After we decided on the Fire and Grass types, we still had to decide on Oshawott's evolutions — so we made them into Japanese Samurai. When we came up with the idea that Dewott can remove the shell from his stomach and use it as a weapon, we felt we'd succeeded in making him a Samurai."
