Nikki Fernandez was one of the middle section survivors from Flight 815. She spent most of her time on the Island isolated from the other survivors with her boyfriend Paulo. Before the Island, she had staged an affair with a producer whom the pair then murdered and robbed. They lost the diamonds they stole in the crash and spent much of their time on the Island trying to recover them. After her greed and anger drove her to throw a female Medusa spider onto Paulo, a male spider bit her, paralyzing her. The survivors mistook her for dead and killed her by burying her alive.
