Onix has a magnet in its brain. It acts as a compass so that this Pokémon does not lose direction while it is tunneling. As it grows older, its body becomes increasingly rounder and smoother. It usually lives underground. It searches for food while boring its way through the ground at 50 miles per hour. Burrows at high speed in search of food. The tunnels it leaves are used as homes by Diglett.
