Luxray is based on a full-grown lion with a blue coat and a black, spiked mane. Black fur covers most of its body except the backs of it legs, midsection and some of its face. It has light-blue legs with three yellow rings on the backs. On its rear is a spiked tuft of fur. Its tail ends in a golden star, similar to that of the constellation Leo the Lion. It has red scleras and yellow eyes.
Luxray has the abilities Intimidate which halves the opponents attack when Luxray has just come out or an opponent switches a Pokémon
or when it's the start of a battle. It can also possess Rivalry, which doubles Luxray's Attack when the opponent is the same gender, and halves Luxray's Attack if it is the opposite gender.
In the Pokémon Adventures Manga, Pearl owns a Luxray.
Marble owns a Luxray as her partner. Sadly, it had lost its ability to use electric attacks right after it evolved. Marble's Luxray tried to stop a criminal, but Officer Jenny's Arcanine took care of the criminal when Luxray failed. Marble was about to pet Luxray to calm him down, but Luxray growled at her and ran off. But later, Pikachu used Thunderbolt on Luxray, and it regained its ability to use electric attacks.
The Gym Leader, Volkner has a Luxray that helped restore power. Later on during Ash's final gym battle, it defeated Pikachu. However, it lost to Infernape after it activated Blaze.
