Gold, Silver and Crystal Chapter
Jasmine receives a call from the Elderly Man at the Day Care, who informs her that her Pokémon has hatched. She expresses her excitement over the news, telling her grandfather that she will bring him some tangerines when she arrives. While at Ecruteak City, Jasmine wonders what sort of Pokémon it will hatch into, stating that she cannot wait. However, a sudden earthquake ripples through the area, as the ground beneath Jasmine collapses. She then falls into the dark abyss alongside her Magneton. Later, the Elderly Couple at the Day Care receive a telegram informing them of the situation at Ecruteak City, wondering whether Jasmine got caught up in it. The Elderly Woman then sends the exhausted Gold to look for their granddaughter.
Later, Jasmine lapses from unconsciousness in the Tin Tower, caught underneath a slab of rubble. She states that she went up there to escape from the constant tremors, telling her Amphy to send out a signal to alert the outside world of her presence. As Gold makes his way to the city, he sees Jasmine's Amphy lighting up a beacon within the Tin Tower. As Jasmine straggles within the structurally unsound building, Silver appears before her. She asks who he is, as Silver frees Jasmine from the rubble. Suddenly, Gold enters the room where the light is emanating from, and notices Silver carrying the unconscious Jasmine. The two eye each other off, as Silver hands Jasmine to him, telling him to leave the building immediately. However, before Gold can make away with her, the exit begins to cave in. In a split second decision, Amphy takes Jasmine on his back, prior to Gold hurling them through the crumbling exit.
After the crisis is absolved, Jasmine awakens at the temporary refuge camp. She asks the doctors where she is, to which they inform her of the situation. Jasmine asks of the person who rescued her from the collapsing pagoda, but the doctors tell her that her Amphy was the one whom rescued her from the ruins. She wonders whether her ordeal was just a dream, but reassures herself that she definitely remembers two more people within the pagoda. Jasmine asks of the situation regarding the pagoda, to which one of them informs her that they will have to wait until morning to find out the extent of the damage.
Later, during the Gym Leader Tournament, Jasmine fought against Brock. Jasmine's main Pokémon Steelix, was disguised as an Onix because she believed that people would dislike the idea of a Steel-type Pokémon. The match goes in favour of Jasmine, after her Steelix won due to its significant type advantage over Brock's Pokémon.
