Shinx is the youngest of two Pokemon in her family having an older brother who is a Luxio. She and her brother lived with their mother, Luxray. Later in life, she became a member of the Pokemon Mystery Dungeon Rescue Team.
Shinx is a very spoiled Pokemon being the daughter of a Luxray who is on the Pokemon Rescue Team. But she is very sweet and cares for others. Because she and Vulpix are daughters of Pokemon Rescue Team Members, bad Pokemon often go after them either to hold them hostage or hold them for ransom.
