Luxray is an Electric Pokemon type, resembling a fully-grown Lion, and can see clearly through walls to track down its prey and seek for others. Luxray is able to track down Culprits and work with the good guys to beat the bad guys. Luxray isn't evil.

Luxray actually survived the incident involving Sorrel and a cold night (In "Pokemon Movie: I Choose You"). How? He'll tell you. But, Luxray rather keeps that a secret till he's down to his lie. He likes Cookies.
