Reshiram and its counterpart Zekrom are based on the concept of yin and yang in Taoism, directly referenced by Reshiram's Japanese species: the White Yang Pokémon. According to Ken Sugimori, Reshiram has a light, airy, feminine design to contrast to Zekrom's tough and masculine design (despite this, it speaks with a distinctly male voice in both versions of the 14th movie). Its tail, the center point of its design, is based on an electric turbine.[1] Appearance-wise, it resembles a mix of animals, including a bird, a pterosaur, and a Wyvern. The crest on its head and its feathers resemble smoke trails, as well as white fire, which can burn up to temperatures of 1,500 °C (2,730 °F). The mythology about how Zekrom and Reshiram came about, regarding two brothers infighting, also bears some similarities to Romulus and Remus or Cain and Abel. There is also some resemblance to the Zoroastrian belief of two equally powerful deities, one representing light and truth, and the other representing lies and darkness. In this case, Reshiram can resemble Ahura Mazda, due to its light and winged appearance, and the fact that it sided with truth, but also the fact that Reshiram is a Fire-type Pokémon, and Ahura Mazda was associated with fire.
