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, Gentleman Preston and Lass Connie, 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.
After the player has earned all 16 Badges, they can return to the Gym, where Jasmine offers to trade them a Steelix in exchange for any Pokémon they offer.
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.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
The Olivine Gym first appeared in Fight for the Light!. After a long journey, Ash and his friends finally reached Olivine City, and Ash was eager for a Gymbattle. 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, but rather her apprentice, Janina. She apologized for misleading Ash, and he forgave her before trying to challenge Jasmine. However, she said that wasn't in the mood for a battle, because Sparkle, the Ampharos who provided the light for the Olivine Lighthouse, had gotten very sick. The only way to treat it was with medicine found in Cianwood City. As a result, Ash and the others accompanied Janina to Cianwood to pick up the medicine.
After his adventures in the Whirl Islands, Ash returned to Olivine City to finally have his Gym battle with Jasmine in Nerves of Steelix!. She accepted his challenge, with Janina serving as the referee. After Pikachu defeated her Magnemite, Jasmine sent out her Steelix, which quickly defeated the Electric type. However, Cyndaquil managed to defeat the Iron Snake Pokémon, earning Ash his Mineral Badge.
Jasmine's Magnemite was seen for the first time in Fight for the Light!, riding on Jasmine's shoulder throughout 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.
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 IVremakes, 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.
The Olivine Gym's design in Generation II could be a reference to the fact that Jasmine used to train Rock-type Pokémon sometime in the past.
