Onix (Japanese: イワーク Iwark) is a dual-type Rock/Ground Pokémon.

It evolves into Steelix when traded holding a Metal Coat.

Biology

Physiology

Onix basically resembles a giant chain of gray boulders, with a rocky spine on its head. 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. A fully grown Onix measures at an enormous 28 feet 10 inches, or 8.8 meters.

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. If Onix takes a hard enough blow and its body falls apart, it can regrow the rest in a matter of a few weeks. It shares this trait with Arbok.

Behavior

They are very hot headed 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. It is most common in Kanto, Johto, and Sinnoh.

Diet

Main article: Pokémon food

Onix eats large boulders.

Major appearances

Brock's Onix

Onix's first major appearance was 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 some time before Grating Spaces, it evolved into a Steelix.

Other

An Onix made its debut appearance in Pokémon - I Choose You!. It was the next Pokémon an unknown Trainer chose after the opponent's Gengar put their Nidorino to sleep.

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 afterward.

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.

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 King Onix that he and his friends weren't bad by defeating it 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 Turtwig, followed by 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!.

Minor appearances

Trivia

  • In Generation I, Onix was the longest Pokémon, but in Generation II, it was dropped to second place by its evolution Steelix. When Wailord was introduced in Generation III, it became the third longest.
  • Onix is the first Pokémon in the National Pokédex order that gained an evolution when it did not evolve from or into another Pokémon in its debut Generation.
  • Onix is the largest and heaviest Pokémon that evolves once.
  • Onix, in Generation I, is the highest-level non-legendary wild Pokémon available without the use of a glitch that the Pokédex has recorded data on its location. Onix can be found in Kanto's Victory Road at level 49.
    • However, Ditto up to level 65 can be found in the Cerulean Cave, but in the Generation I games, the Pokédex does not inform the player of the Pokémon available in the cave, as Pokémon only found there would just display as "Area Unknown" in the Area section of the Pokédex.
  • By being under the ownership of Bruno in Generation II, Onix is one of the few unevolved Pokémon that can evolve in the same generation as that of the Elite Four member to whom it belongs, the others being Dragonair, Shelgon, Haunter, and Sealeo. However, it's the only one where the Elite Four member doesn't own its evolved form.
  • Of all the Pokémon that can evolve, Onix has the highest base Defense.
  • Onix is the largest Pokémon that can legally hatch from an egg that has no pre-evolution.
  • Despite being the "Rock Snake" Pokémon, Onix and its evolution Steelix cannot learn Coil.
  • Onix is one of four Pokémon which changes its primary type upon evolution (from Rock to Steel). The others are Azurill, Swablu and Eevee.
    • Onix and Swablu are also the only dual-typed Pokémon that have their primary type change during evolution.
      • In addition, Onix is the only Pokémon whose evolved form has a type-advantage against its predecessor, without that type being identical to both Pokémon (such as Dragon or Ghost).
  • In the anime, Onix is commonly mistaken to be roaring when it speaks. However, it is actually saying its Japanese name, Iwark.
  • Onix family is the only one whose all members can be acquired with in-game trades. However it's only possible in Pokémon HeartGold and SoulSilver where you can trade Bellsprout for Onix in Violet City and any pokemon for Steelix in Olivine City.

Origin

Onix is most likely based on a combination of a snake and earthworm. It may also been based on the wyrm, a type of dragon that has been presented as limbless and burrowing.

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.
