Onix

Species          Quote “Burrows at high speed in search of food. The tunnels it leaves are used as homes by Diglett.” — Onix's Pokédex entry[src]     C Onix   [Edit]   [Talk]

Onix<sup>(JPJapanese: イワーク

Romaji: Iwark)</sup> is a species of Pokémon in the series of the same name. It is a dual-type Rock/Ground Pokémon that made its first appearance in the first generation games Red and Blue. It evolves into Steelix after being traded with the Metal Coat.

Physiology and Behaviour[]

Onix is a Pokémon composed of a giant chain of gray boulders that become smaller towards the tail. Its length makes it the tallest Rock-type Pokémon. It has black eyes and a rounded snout. On top of its head is a rocky spine. As it grows older, it becomes more rounded and smoother, eventually becoming similar to black diamonds. Inside its brain is a magnet that serves as an internal compass, guiding Onix wherever they need to go and preventing them from getting lost while digging.

Onix tunnels under the ground at over 50 miles (80 kilometers) per hour, which causes tremors and a terrifying roar that echoes a long way. Hard objects encountered while tunneling are absorbed into its body, which makes it very sturdy. It also consumes the boulders for food. The massive, winding tunnels it leaves behind are used as homes by Diglett. As seen in the Pokémon Stadium series, Onix is capable of rotating its head, or any part of its body, in a full 360 degrees. It is a very aggressive Pokémon that will constantly attack humans and other Pokémon when in pain, as seen in the anime. As seen in the Pokémon Adventures manga, Onix can be separated from its body segments in battle and be fine later on, either regenerating or reattaching to its body segments. It is said that an Onix that lives for about 100 years will evolve into a Steelix after its composition becomes more diamond-like. It can be found in mountains and caves.

Onix can be summoned via Poké Ball. Once thrown, it flies up into the sky and uses Rock Throw on the player's opponents. This will hit everyone on the field except Kirby if he uses his down special move.

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

Trophy descriptions[]

In the anime[]

Starting in Showdown in Pewter City, Brock used an Onix in his journeys in Kanto and Johto before giving it to his little brother, Forrest, for him to train in A Family That Battles Together Stays Together!. At some point before Grating Spaces!, it evolved into a Steelix.

Trivia[]

• Onix is the heaviest and tallest unevolved Pokémon.
• Onix is the only unevolved Pokémon that is used in the Pokémon World Tournament by Trainers beyond the right attendant, being used in all of Brock's teams.
• The Onix line is the only multi-stage evolutionary family which can be completely acquired with in-game trades. However, this is only possible in Pokémon HeartGold and SoulSilver, in which the player can trade Bellsprout for Onix in Violet City, and any Pokémon for Steelix in Olivine City.
