Steelix is a lustrous, silvery gray snake. They are about 30 feet long. Their body is made up of rock-like sections, three of which have massive rock spikes coming out of them. They have a massive head mainly made up of their jaw. The jaw is large and wide with sets of large square teeth inside. Along their bottom jaw are a pair of ridges (varies with gender). Their eye sockets are slightly set in, giving them good eye protection. Underneath their bottom jaw there are small square domes. Their heads have two long ridges going from the eyes up to the top of their heads. Their jaws also have massive ridges where they meet their skull. Their tail ends in a long sharp point, but with a blunt tip. Steelix's rock-like sections don't look perfect and can easily be mistaken for rocks, for they have many chips and scrapes all along them from fights and tunneling.
Gender differences
A male Steelix has two pairs of sharp ridges on each side of its bottom jaw, one big one and one slightly smaller one. A female Steelix has only one pair of ridges on either side of its bottom jaw, each the approximate size of the male's larger ridges.
Special abilities
Steelix has a body that is stated to be harder than diamond. They can create Sandstorms by spinning their body in circles, and they can tighten and harden their tail to attack.
Behavior
Steelix are rather rash and often charge into situations without thinking about the consequences of their actions. Often if they are disturbed, they will attack anything rather than just the actual being responsible for disturbing them. They are usually aggressive towards other Pokémon that happen to live in the area they are living in. Steelix are very tenacious; they don't give up until they are beaten and are often adamant about their choice of action. Steelix like to burrow underground and prefer to live inside mountains or on mountains, or even caves.
Although Steelix require an item to evolve from Onix, they can sometimes be found in the wild, where they populate deep caverns, tunnels, and an old temple in the Sinnoh region and a cliffside cave in the Johto region. As they live far underground, miles from the surface, they don't often surface above ground unless provoked. It is said that when an earthquake happens, multiple Steelix are battling far below the surface.
Team Rocket accidentally stuck three shovels into the head of an underground Steelix while digging a pitfall trap in Faced with Steelix Determination. It went on to terrorize a village of Bidoof until the shovels were removed through the combined efforts of multiple Bidoof, Ash's Staravia, and his Pikachu.
In Dealing With Defensive Types!, a Steelix belonging to Byron was used in the Gymbattle against Ash. It put up a tough fight, defeating Ash's Buizel, despite its type advantage and then fought against Ash's Chimchar. Despite its exhaustion from its earlier battle, Chimchar was able to defeat Steelix after a prolonged battle.
Steelix, the Iron Snake Pokémon, and the evolved form of Onix. Steelix's body is much harder than any metal as it is tempered underground under high pressure and heat.
In Pokémon Adventures, Jasmine used a Steelix disguised as an Onix in the Gym Leader's Tournament of the opening ceremonies in the Pokémon League. Brock's Onix tightened its grip on the hidden steel Pokémon, but against the unusual hardiness of its evolution, it only hurt itself, and was eventually defeated after Steelix's stone "hide" scraped off and it was exposed. Jasmine explains that because it was a newly discovered species only so far uncovered by Crystal's capture, she tried to hide its identity in the hopes that it wouldn't be treated as simple eye candy for curious spectators. Years later, Carr of the Team Rocket beast trio used one against Red's Poli as they clashed in the Sevii Islands. It was swung aside rather easily as it was interrupted in its rampage, and after a failed Iron Tail, it was beaten by a smart Mind Reader maneuver. Another was on Iron Island and was used for training with Riley.
In the Pokémon Diamond and Pearl Adventure! manga
Byron has two Steelix which were used in the challenge in which they served as walls to prevent Hareta from getting to the top in Challenge! The Fortress Of Steel!!.
A combination of Steel- and Ground-types, Steelix are the longest Pokémon yet to be discovered, reaching over 30 feet in length. Since they live so deep under the surface of the earth, the intense pressure has made their bodies stronger than diamonds. Evolved from Onix, Steelix is every bit as intimidating as its relative.
