Codenamed Halo, Violet is the product of the spirit from a Mother Box reviving the body of Gabrielle Daou, a dead Quraci refugee who’d been used as a test subject to stimulating a person’s “meta-gene.” Seeing herself as a new individual, they names themself Violet Harper.
Violet woke up in a “blank slate” with minor traces of Daou’s personality, memories, and fondness for the hijab (as wearing it makes her feel more comfortable), as well as fleeting access to the Mother Box’s knowledge and some of its powers. She was then rescued by Tigress, who gave her the nickname “Halo”, and went on to live with her afterward before joining Nightwing’s Outsiders. During their time with the group, she discovers a vast range of powerful abilities and develop a romantic relationship with the exiled Prince Brion of Markovia. She and the other three members later joined the Team.
Halo doesn’t see herself as either female or male, instead as the combination of mother box and human combining to make something new, which Halo describes as “just me.” However, she still prefers female pronouns.
