Angel

In The King of Fighters 2001, Angel is introduced as an agent of the secret organization known as NESTS. She is assigned to keep an eye on the experiment K9999, whose purpose is to hunt down traitorous experiments that had left NESTS. During the final moments of the tournament, it is revealed that both Angel and K9999 are actually on a mission to kill Kula Diamond and her guardians. Having betrayed NESTS, Angel went on the run and was hunted by the organization's loyalists. Ramon offers her an invitation to join the tournament, which she accepts, tired of living in the shadows and in the mood to do something.
