Foxy/Story

Past
Foxy is a loyal agent of NESTS who was ordered with her colleague, Diana, to supervise the product of the Anti-K' project: Kula Diamond.

The King of Fighters 2000
They were dispatched to eliminate the rogue agent, Zero, as he was considered a burden to their organization.

The King of Fighters 2001
Prior to the 2001 tournament, Foxy was chosen over Diana to form a team with Kula, Angel, and their newest creation K9999. Their main purpose was to dispatch the rogue creations that had escaped from NESTS's grasp, as well as disposing K', Kyo Kusanagi, and anyone who would get in the cartel's way.

Sometime after the tournament's conclusion (when K', Maxima, Whip, and Lin were reaching Igniz via a blimp), K9999 and Angel attack Foxy from behind, fatally injuring her. While it is implied that Foxy is killed by him and Angel, this ending is considered non-canon.

The King of Fighters 2003
After she discovers that the original president of NESTS was murdered by Igniz, she stops her loyalties to the NESTS cartel and joins Diana in becoming an independent party, and helps K' in any way she can.
