Shinx is a quadrupedal feline Pokémon that resembles a lion cub or lynx kitten. Its front half is light blue while the rear is black. The creature has a short tuft of fur on its head and smaller tufts on each cheek, with the top tuft being slightly smaller for females. Shinx features large oval ears with yellow star-shaped markings on their insides, yellow eyes, and a tiny red nose. Its mouth reveals small fangs when open, and it has a black collar around its neck that is encircled by a black marking. The hind paws are black for males and blue for females. Electricity is produced through the contraction of muscles in Shinx's forelegs, causing its fur to glow. When threatened, Shinx can blind predators with brightly gleaming fur, which signals excited trembling when generating tremendous amounts of electricity. Shinx communicates by shining the tip of its tail and shaking it while sending signals to other Shinx. Due to its aggressive nature, taming a Shinx requires great patience.
