Digimon Adventure 02
Gatomon first became Nefertimon on the day the Digi-Egg of Light was found when she, Kari, T.K. and Patamon ended up in a cave after escaping some Dark-Ringed Tyrannomon. Kari managed to obtain the Digi-Egg and evoked its power, allowing Gatomon to Armor Digivolve to Nefertimon. Since then, Nefertimon has been a valuable fighter during the Digimon Emperor's reign of terror as well as the chaos caused by Arukenimon, Mummymon and BlackWarGreymon. But during the battle with MaloMyotismon, Nefertimon was manifested as a result of Kari's dream for a better world.

Note
Gatomon armor digivolving to Nefertimon is a plot-hole. Gatomon is a champion level digimon, while the other digimon are rookies when they armor digivolve. Though her strength was reduced to that of a rookie without her tail ring, it should have been Salamon - Gatomon's rookie counterpart - who armor digivolved.

Digimon Frontier
Caretaker of Ophanimon's Castle of Light, Nefertimon held the Fractal Code key for the remaining land of the Digital World in her body. She was destroyed by Dynasmon during the DigiDestined's vain attempt to defend the castle, resulting in Lucemon being completely resurrected.
