Biology

Physiology

Onix basically resembles a giant chain of gray boulders. The 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.

Gender differences

None.

Special abilities

It tunnels under the ground at over fifty miles per hour. Its hard head and sturdy body are the only thing that protects Onix from the tremors it causes.

Behavior

They are very hot headed Pokémon and will constantly attack humans and Pokémon when various objects are caught in its cragged body in the wild, but under the care of trainers they 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, also cragged mountains with abandoned mines.

Diet

In the anime

Onix first appeared in Showdown in Pewter City under the ownership of Brock. He used it in his journeys in Kanto and Johto before giving it to his little brother, Forrest, in A Family That Battles Together, Stays Together. At sometime before Grating Spaces it evolved into a Steelix.

Ash and co. encountered a giant Onix in To Master the Onixpected. It was on a rampage until Bruno managed to get a Sandslash from under the Rock Snake Pokémon's "skin." Bruno captured the Onix afterwards.

The Crystal Onix featured a Crystal Onix. Ash and co. helped a glass sculptor named Mateo search for it because Mateo believed it would help inspire him to be better at his craft.

In Hello Pummelo, Drake of the Orange Crew owns an Onix and he used it to fight Ash's Squirtle in the second round in the Orange League Champion match. During the battle with Squirtle, Drake's Onix dug underground and emerged to use Bind on Squirtle, but Squirtle used Withdraw followed by a Hydro Pump, soaking Drake's Onix into submission. After drenching Drake's Onix, Squirtle defeated the Onix with a Skull Bash.

Janina, Jasmine's apprentice, has an Onix in the episode Fight for the Light. Her Onix was heavily coated in wax for protection against Water attacks.

A "King Onix" was featured in Hooked on Onix. Team Rocket tricked King Onix into thinking Ash and co. were going to destroy his kingdom. When Ash managed to convince that he and his friends weren't bad by defeating King Onix in a battle, Team Rocket tried to steal the royal Rock Snake Pokémon (but their plan was foiled as usual).

Roark's Onix was first seen in Shapes of Things to Come where it was used against Paul's Elekid and Chimchar. In A Gruff Act to Follow, it defeated Ash's Pikachu but Pikachu managed to defeat it in a rematch in O'er the Rampardos we Watched.

A rampaging Onix appeared in A Maze-ing Race!.

In the manga

Brock has an Onix in Pokémon Zensho, the Electric Tale of Pikachu, and Pocket Monsters.

In the Pokémon Special manga

Onix debuts in Onix is On! of the Red, Green & Blue chapter as Brock's main Pokémon, however a picture of it is showed on a leaflet in Wanted: Pikachu!. Onix later continues to make appearances with Brock in various volumes onwards.

Bruno owns a pair of Onix, on which he battles Bill, Lt. Surge and Red in Cerise Island. The Onix later manage to carry Bruno and Koga off the collapsing island.

In the TCG

Main article: Onix (TCG)

Other appearances

Super Smash Bros.

In the original Super Smash Bros., Onix was obtainable in a Poké Ball. Once thrown it would fly up into the sky. A few seconds later it would begin to use Rock Throw which would pummel anyone who is not the user or team mate.

Super Smash Bros. Melee

Onix is the second Poké Float to appear. It provides a horizontally flat area all the time it is on-screen, though it becomes diagonal as it leaves the screen.

Origin

Name origin

Onix's name is a corruption of onyx, a mineral. Its Japanese name may be a combination of 岩 iwa, rock, and スネ−ク snake.

It has been suggested that Onix is based on a wyrm, a type of dragon that has been presented as limbless and burrowing.
