Anime

Brock's Onix.

Main articles: Brock's Steelix and Onix (TB089)

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.

Trivia

  • Onix is the tallest Pokémon that is capable of evolution.
  • In Super Smash Bros., Onix is one of the Pokémon that can be freed from Poké Balls. During this time, it uses the move Rock Slide.

Origin

Onix is based on a snake and/or an earthworm. It may also be a pun on the terms "rock python."

Etymology

Its name comes from "Onyx," a black stone that is commonly used in jewelry.

Iwāku comes from 岩 (iwa, rock) and possibly the root "arc," meaning "ruler."
