When Locus first debuted, she was seen with long blonde hair. However, when the events of Operation: Zero Tolerance came about, her appearance seemed to be African-American. There were speculations of her having either a secondary mutation or just to differentiate her from Magik.
Locus was killed by an enraged Sabretooth while Weapon X was underway. She was recruited because of her powers and was responsible for two of her teammates, Washout and Brent Jackson.
