The Olivine Gym (Japanese: アサギジム Asagi Gym) is the official Gym of Olivine City. It is based on Steel-type Pokémon. The Gym Leader is Jasmine. Trainers who defeat her receive the Mineral Badge.

In the games

Generation II

Olivine City
Pokémon Gym
Leader: Jasmine
The Steel-Clad Defense Girl

In Pokémon Gold, Silver, and Crystal, the Gym is completely free from any Gym Trainers or puzzles, allowing the player to go straight to Jasmine immediately after clearing the Glitter Lighthouse.

The Olivine Gym resembles the Pewter Gym, being designed after a Japanese rock garden. Jasmine stands on a stone platform at the back of the Gym.

A field based on the Gym also appears in Pokémon Stadium 2's Johto Gym Leader Castle.

Generation IV

Olivine City Pokémon Gym
Leader: Jasmine
The Steel-Clad Defense Girl

In Pokémon HeartGold and SoulSilver, the Gym has changed, more clearly reflecting its Steel-type theme. There are now two Gym Trainers, but they won't battle the player. Instead, they simply express their gratitude of the player for helping the sick Ampharos at the Glitter Lighthouse, thus serving no problem for reaching Jasmine.

The Gym's interior design has been notably changed, now being a metallic building with steel arcs built over the path to the Gym Leader. Jasmine is standing on a low, covered steel platform at the end of the Gym.

In the anime

Olivine Gym has made two appearances in the anime. It first appeared in Fight for the Light!. After a long journey, Ash and his friends had finally reached Olivine, and Ash was eager for a Gym battle. When he entered the Gym, a girl claiming to be Jasmine challenged him to a battle. After losing to her Onix, Ash learned that the girl wasn't Jasmine at all. It was her apprentice, Janina. She apologized for misleading Ash, and the Trainer forgave her.

Jasmine herself wasn't in the mood for a battle. Sparkle, the Ampharos who provided the light for the Olivine Lighthouse, had gotten very sick. The way to treat it was with medicine found in Cianwood City. Ash and the others went with Janina to Cianwood to pick up the medicine.

After his adventures in the Whirl Islands, Ash returned to Olivine to battle Jasmine again in Nerves of Steelix!. She accepted his challenge, with Janina serving as referee. After Pikachu defeated her Magnemite, she sent out her Steelix, which quickly defeated the Electric-type. But Cyndaquil managed to defeat the Iron Snake Pokémon, earning Ash his Mineral Badge.

Pokémon used in Gym

Used by Janina
Janina's Onix
Onix is Janina's only known Pokémon. It first appeared when Janina posed as Jasmine and battled Ash in a Gym battle which she cheated using a water resistant polish. Ash called out his Totodile and used Water Gun which did no damage from the polish, Onix then tackled Totodile and fainted it. Ash then sent out Pikachu and used Agility before being stopped by Jasmine. Jasmine then told Janina to scrub the polish off Onix which she did.

Later, when Team Rocket were causing havoc in the Olivine Lighthouse. Onix saw the smoke caused by Weezing, so Janina decided to go and investigate. She found Team Rocket in their balloon. Jessie ordered Arbok to use Poison Sting which Onix deflected. Team Rocket tried to escape on the sea where Onix couldn't go. Onix went on the tsunami barriers and swung its body latching onto Arbok, swinging them and sending them blasting off.

Onix made a brief cameo in Nerves of Steelix! with Janina.

Onix's known moves are Tackle and Wrap*.

Jasmine's Magnemite
Jasmine's Magnemite was seen for the first time in Fight for the Light!, riding on Jasmine's shoulder through the whole episode. It was also the first Pokémon that Jasmine used in her Gym battle with Ash in Nerves of Steelix!, sending it against Ash's Pikachu. Despite proving itself very fast and pretty strong, it was finally knocked out by Pikachu's Quick Attack.

Magnemite's only known move is Thunder Wave.

  • The Olivine Gym is one of three Gyms in the games thus far not to have any Trainers but the Leader. The others are Generation II's Viridian Gym and Cinnabar Gym.
    • In the Generation IV remakes, the Gym contains Gentleman Preston and Lass Connie, who were battled by the player at the Glitter Lighthouse, though neither Trainer challenges the player in the Gym. Strangely, neither Trainer uses Steel-type Pokémon when battled at the Glitter Lighthouse. The remakes also add Trainers to Viridian Gym and Cinnabar Gym, leaving Olivine Gym the only Gym to never have any other Trainers battled in it except for the Gym Leader.
