Virtually nothing is known of the past of the woman known only as Annalee before she joined the underground community of mutants known as the Morlocks who lived in "The Alley", a huge tunnel located beneath Manhattan. Annalee's own four children were slain and this caused her to attempt to force the four original members of the young superhuman children known as Power Pack to become her foster children. Her repeated attempts failed, but she later found happiness caring for the young power-draining Morlock known as Leech.
Annalee was slain by Scalphunter, leader of the superhuman team of assassins known as the Marauders, during the villains' massacre of the Morlock community.
