Jasmine was first seen with a Steelix in Nerves of Steelix!, where it rescued Ash's Pikachu after he had been kidnapped by Team Rocket. It easily managed to knock over their mecha after Brock and Janina's Onix had failed to do so. It then disabled the mecha with Crunch, and once Pikachu was safely back in Ash's possession, sent Team Rocket blasting off with a powerful swing of its Iron Tail. Steelix was used again later during the second round in her Gymbattle against Ash. It was put up against Ash's Pikachu, who was fatigued from his previous battle against Jasmine's Magnemite. Additionally, his Electric-type moves had no effect on the part Ground-type Steelix, with his Quick Attack not doing much damage to Steelix's hard body. After a valiant effort, Pikachu was easily defeated by a slam from Steelix's Iron Tail.
Steelix facing Ash's Cyndaquil
Ash then sent out his Cyndaquil to battle against Steelix. Despite being at a type disadvantage, Steelix managed to defend itself against Cyndaquil's Flamethrower through use of its Sandstorm and then disappeared from the field by Digging underground. After resurfacing, its attempts to attack the Fire Mouse Pokémon failed as Cyndaquil easily managed to dodge them all. It then reused its Sandstorm and Dig combination to defend against another Flamethrower. After continuously failing to hit one another, Ash had Cyndaquil use Smokescreen and use Steelix's holes to hide in. Once the smoke had been cleared, Cyndaquil managed to land a direct hit with Flamethrower from its hiding place. Jasmine then had her Steelix use Iron Tail on the ground, causing the tunnels below to cave in, forcing Cyndaquil out of the hole. After hitting Cyndaquil with Iron Tail, it looked like Steelix had won. However, Cyndaquil managed to recover and avoid being knocked out through use of Smokescreen. Steelix tried to use Sandstorm to defend against Flamethrower, but this tactic was turned against it in the end as its Sandstorm was set ablaze, surrounding Steelix in a tornado of superheated sand, defeating the Iron Snake Pokémon, and earning Ash the Mineral Badge.
Not much is known about Steelix, as it and its Trainer, Jasmine, have appeared in very few episodes. However, Steelix has been shown to be quite capable in battle, as, during Ash's Olivine Gym battle, it easily defeated Pikachu, who was unable to deal any meaningful damage to it before fainting. Steelix has proven to be a difficult opponent even when at a type disadvantage, as shown in its battle against Cyndaquil. During the fight, it employed a frightening strategy involving Sandstorm and Dig, where it created a Sandstorm to defend and obscure itself as it went underground before coming back up to strike the Fire Mouse Pokémon.
Steelix have been used by the Gym Leader Jasmine since her debut in Pokémon Gold and Silver and has appeared in every game she has appeared in some capacity.
Rusty is traded to the player in Pokémon HeartGold and SoulSilver in exchange for any Pokémon, after obtaining the National Pokédex and exchanging phone numbers with Jasmine at the Olivine City Cafe (left of the Pokémon center) between 1:00 PM and 2:00 PM. Rusty appears to be a different Steelix than the one used in Gym battles, as he is consistently shown to be a male, while the battling Pokémon is female in Generation IV games. Rusty's level will be equal to the level of the Pokémon you trade for him. The trade also does not affect Jasmine's team in subsequent battles.
Jasmine's Steelix, nicknamed (ハガネちゃんHagane-chan) in the original Japanese version, debuted in Capital Kabutops. It was wearing a layer of rock over its steel body, causing everyone to believe it was an Onix. It battled Brock's Onix, and as the two constricted each other, Onix took damage due to Steelix's much harder body and Steelix's outer coating began to chip and fall off. Exposed as being a fraud, Steelix broke out of its disguise and revealed itself to be Steelix. It then easily took down Brock's Onix, and Jasmine explained that her Steelix also used to be an Onix until it evolved. After Professor Oak explained that Steelix has yet to be officially classified, Jasmine explained that because of its rarity, she hid Steelix's identity so it wouldn't be exploited.

Steelix in Pokémon Pocket Monsters
Steelix appeared in Tyrogue's in Love?!. After Tyrogue confessed his feelings to Jasmine by giving her flowers, Steelix rose out of the ground as soon as Jasmine was about to accept the gift. As Steelix was after the same thing, both he and Tyrogue fought for her. As a result, Clefairy gave them some challenges in which they drank some milk, ate some snack balls and gag battled in the end.
However, Jasmine stopped the fighting between Steelix and Tyrogue. She took out a machine to determine who was compatible. As the machine pointed to Tyrogue and then to Pikachu, Steelix slammed his head onto the machine in frustration.
