Halo is a light-powered superhero and member of The Team.
Gabrielle Daou was a refugee Quraci girl who worked at the castle of the Markovian Royal Family. She accepted a bribe to allow in the killer who killed King Viktor and Queen Ilona. She was then captured as a means to erase any evidence. While captured, Gabrielle was tested for the Meta-Gene but her results were negative. The captors then killed Gabrielle through an overdose of morphine and her body was to be buried with several other dead teenagers.
A Mother Box fused with her corpse and Gabrielle was resurrected with incredible powers tied to her colorful aura. Amnesiac and no longer recognizing herself as Gabrielle Daou, she adopted the name Violet Harper suggested by her then future boyfriend Prince Brion Markov, in reference to the violet color of her aura and Will Harper.
As Gabrielle's memories returned, Violet felt guilty about the events that led to the murder of Brion and Tara's parents, which drove her away from her boyfriend.
