Steelix can have one of two abilities: Rock Head, which prevents this Pokémon from receiving recoil damage from recoil-causing moves; or Sturdy, which gives this Pokémon an immunity from falling to a One-Hit KO move such as Fissure or Horn Drill, and starting with Generation V, Pokémon with Sturdy cannot be KO'd in one hit when it has full HP. Steelix that come from the Dream World have the ability Sheer Force, which gives moves that have a secondary effect a 33% increase in power, but those moves also lose their secondary effect.
Steelix wasn't available in Generation I, but from Generation II onwards Onix could evolve into Steelix if it was traded to another game while holding a Metal Coat. When evolved Steelix loses the Rock type it has a Onix and instead it's main type becomes Steel.
Steelix is in the Mineral Egg Group, and will hatch after 6,400 steps. It will take an Steelix one million Experience Points to reach level 100.
Steelix takes the appearance of a ginormous metallic snake.
 Gender Differences
Male Steelix will have an extra front overbite tooth on its lower jaw, whereas the Female Steelix will only have the one overbiting tooth.
 Game Information
 Original Games
Steelix was introduced in Generation II, and the only way to obtain one in Generation 2 and Generation III was to evolve Onix. Generation IV would change that, as for the first time Steelix could be obtained in the wild. In Diamond and Pearl Steelix could be obtained at Iron Mountain, Snowpoint Temple, and Victory Road; and at Iron Island and Victory Road in Platinum.
In HeartGold and SoulSilver, Steelix can be found at Mt Silver and The Cliff Cave.
While Onix can be found at the lowest parts of Relic Castle in the Generation V games Black and White, at B6 and the Maze, the only way to obtain a Steelix would be to evolve Onix in Black and White.
 Spin-off Games
Steelix appears in Trozei at Endless Level 12, Pair Trozei, Forever Level 61 and Mr. Who's Den. In the first Dungeon game Steelix can be obtained by evolving Onix.
Steelix can be recruited in the Generation IV Dungeon games Time&Darkness/Sky at Sky Stariway from 1F-49F. Onix appears in Stormy Adventure Squad on the Path to Treasure Mountain at B23 & B24.
Steelix has yet to appear in a Pokémon Ranger game.
 Trading Card Game
Steelix has appeared in 12 different sets, two of which twice, to total 14 different cards. The Steelix from the Rising Rivals set is the lone Uncommon card. The Neo Genesis, VS (2), Aquapolis, Skyridge, EX Sandstorm, EX Team Rocket Returns, EX Unseen Forces, Diamond and Pearl, Stormfront, and Unleashed (2) are Rare Cards, while the Shining Steelix from the Neo Destiny Set is one of the Hidden Cards from that set and is a three-star rare card.
 Anime/Manga Information
Johto Gym Leader Jasmine was the first to utilize a Steelix in battle, which was the debut of Steelix in the episode Nerves of Steelix. Jasmine would also use her Steelix in an appearance in the episode Four Roads Diverged in a Pokémon Port.
Brock would return to Pewter Gym to have found that his Onix evolved into a Steelix while he was away in the episode Grating Spaces. Harrison, Morrison, and Byron have also used a Steelix in their battles. Other Steelix appearances were by other trainers or in the wild.
Steelix has appeared in two films: Lucario & The Mystery of Mew and Giratina & The Sky Warrior with minor roles in each.
