Onix

Onix (Japanese: イワーク Iwark) is a Rock/Ground-type Rock Snake Pokémon that is the pre-evolved form of Steelix when holding a Metal Coat.

Apperance[]

Voice actor: Unshō Ishizuka (both English and Japanese)

Onix resembles a giant chain of gray boulders, with a rocky spine on its head. This Pokémon has a magnet in its brain that serves as an internal compass. Onix's body becomes more rounded and smoother as it grows with age. A fully-grown Onix measures at an enormous 28 feet 10 inches, or 8.8 meters. Its height is 28'10" and weight is 463.0 lbs.

Special Abilities[]

Onix can have the ability Rock Head or the ability Sturdy. Rock Head prevents Onix from recoiling. Sturdy gives Onix immunity to OHKO moves. Onix tunnel under the ground at over fifty miles per hour, which causes tremors. It has a compass in its brain that can tell what direction Onix is facing.

Behavior[]

They are very hotheaded Pokémon and will constantly attack humans and Pokémon when various objects are caught in its craggy body. However, domesticated Onix will show signs of distress instead of attacking others.

Habitat[]

Onix can be found in mountains and caves, though they prefer underground tunnels with little light. It can also be found in craggy mountains and abandoned mines.
