Jasmine

Jasmine (Japanese: ミカン Mikan) is the Gym Leader of Olivine City.

Gold, Silver and Crystal
Jasmine makes two appearances in Gen. II and Gen. IV. In Gen. II, she is the Gym Leader of Olivine City. Defeating her will give you the Mineral Badge.

Diamond, Pearl and Platinum
In Gen. IV, she appears when you reach the beach at Sunyshore City and will give you the HM07 Waterfall.

In addition, if you make it to a Master Rank Pokémon Contests, you will go up against her and her Steelix.

She does amazing in the both the Dress up and Dance categories, but falters in the performance of moves.

Manga
She battled Brock in the fight where all Kanto and Johto Gym Leaders fought each other and she won because no one knew there was such a thing as a steel type Pokémon, and Brock was surprised that Onix had another evolution that is none other than Steelix. Professor Oak explained that there was a new discovered type called Steel Type.

Season 4: Johto League Champions
She first appeared when she stopped a battle between Ash and her apprentice Janina. She scolded her for using water-proof wax on her Onix and sent her away. She then declined Ash'd challenge for a Gym Battle, as Sparkle, the Ampharos at the lighthouse, is sick and she must take care of it. After seeing her apprentice battle with her own strength she let her be her apprentice again saying she was never expelled in the first place. This is an example of her tough but fair personality, a trait she did not have in the games.

Season 5: Master Quest
She appeared again in Nerves of Steelix showing off her bravery by jumping onto her Steelix' head from a very high cliff (very different from her game counterpart). She can also be one tough cookie in battle, but in the end, she lost, and as Gym Leader, gave Ash the Mineral Badge.

Season 13: DP Sinnoh League Victors
She made a new appearance in her new HeartGold and SoulSilver look and was happy to see Ash again. She had participated in contest battles with her Steelix learning new things along the way. She lost in a battle with Flint of the Elite Four and strived to become stronger ever since.
