Onix

() is a /-type Pokémon introduced in Generation I.
==Biology==
===Physiology===
Onix is a Rock Snake Pokémon. Its serpentine body is made up of large gray boulders and little pebbles. It has a long horn atop its head and small eyes.
=== Behavior ===
Onix spend most of their time burrowing through the earth, twisting and turning their massive bodies as they dig. They constantly eat while burrowing, consuming boulders, dirt, and whatever else they come across. These tunnels often later become homes and pathways for other subterranean Pokémon, such as Diglett and Druddigon. 
===Natural abilities===
Onix can have the abilities Rock Head or Sturdy. Rock Head prevents Onix from recoiling, while Sturdy gives Onix immunity to OHKO moves . When it is burrowing underground, it can cause rumbles and earthquakes. It can dig at speeds up to 50 MPH. It has a compass in its brain that can tell Onix what direction it is facing.
==Evolution==
Onix evolves into Steelix when traded while holding a Metal Coat.

==Appearances==
===Anime===
Brock received an Onix from his father, Flint, on his 10th birthday, as seen in a flashback in Having a Wailord of a Time. Onix was Brock's first Pokémon and has consistently been his most powerful Pokémon as well. Brock uses this in some occasions during his travels with Ash and Misty. In Pokémon Chronicles, Brock uses Onix for the last time to battle against his ditsy mother, Lola who is responsible for remodeling the Gym and her Mantine to put the Gym back to its former glory. Brock lent his Onix to his younger brother, Forrest until it evolves into Steelix in Grating Spaces! under his care.
The Crystal Onix's first and only appearance is in the anime episode The Crystal Onix. Ash and his friends first heard of it through a note they found in a bottle floating in the ocean. The note was written by a little girl named Marissa. She wanted to find the Crystal Onix to help her brother, Mateo, gain inspiration to make glass Pokémon statues. Mateo told a story of how his grandfather discovered the Crystal Onix and then was able to make extraordinary sculptures afterwards. One of those sculptures included the Crystal Onix itself. In the Best Wishes series during the episode of, Expedition to Onix Island!, a shiny Onix is the leader of several normal Onix in the Onix Island. When Ash and his group are chased by most of the normal Onix, Meloetta did her best to sing her song to calm them down but its no effect until a shiny Onix loudly roars to stop them which causes all of the normal Onix leave and allowing Ash and the group to see its shiny Onix before leaving back to Cynthia's resthouse.
The most powerful Onix after both Brock and Roark was Grant's Onix which it was seen in his battle against Viola's Surskit at the Battle Chateau and its Gym battle against Ash's Froakie by trapping its opponents using Rock Tomb.
