Luxray is a quadrupedal Pokémon resembling a fully-grown lion. While its face, hind legs, torso, and the back of its front legs are blue, much of its body is covered with shaggy, black fur. The fur is longer around the shoulders and the base of the tail, and forms a mane on its head. The mane is larger on the male than on the female. It has yellow eyes with red sclerae, a blunt muzzle, and rounded ears with yellow insides. There are three yellow, half rings on the back of each foreleg. Its long, thin tail is tipped with a yellow four-pointed star.
Luxray has powerful eyesight that is capable of seeing through most objects and walls, like x-ray vision. It uses this ability for hunting and keeping track of its offspring. However this ability requires a lot fo electricity to use. As a result, Luxray needs to sleep for long periods of time in order to store up more energy.
Luxray made its main series debut in Luxray Vision!, under the ownership of Marble. Having recently evolved from Luxio, it was unable to use Electric-type moves and had a serious attitude problem for most of the episode.
Luxray is the only Pokémon with a base stat total of 523.
Luxray appears to be based on a lynx, which possess great eyesight, some myths even depicting them as being able to see through solid objects, a trait Luxray has. Its appearance however, resembles more that of an adult male lion. It may have also been inspired by the mythical sphinx, as its short face, human-like ears, and lion-like appearance are similar. In addition, it may have been inspired by the constellation Leo, due to Luxray's lion-like appearance and the fact that it and its pre-evolved forms bear a signature star shape on the end of their tail. Furthermore, its Japanese name suggests at least some minor influence from tigers.
Luxray's ability to see through solid objects is similar to a modern radiograph or "x-ray machine", explaining the basis for its name and Electric typing.
Luxray may be a combination of lux (Latin for light), x-ray (referring to its x-ray vision), and lynx.
Rentorar may be derived from レントゲン rentogen (discoverer of x-ray radiation), 虎 tora (tiger) and rar/rawr, meaning a roar-like sound.
