Raina was an Inhuman scientist devoted to the studying of human nature. During her youth, she met Calvin Zabo, a mysterious doctor who gave credit to and explained her grandmother's tales and beliefs, passed through her ancestors. She joined HYDRA's Centipede Project, aiming to create Super Soldiers where she transformed John Garrett and Deathlok into near unstoppable killers. After Garrett attempted to take over production of Deathlok Soldiers, she left the Project.
With the help of Calvin Zabo and Daniel Whitehall, Raina was able to locate a Diviner and the Kree city. There, she unlocked the Terrigen Crystals within the Diviner, triggering her Inhuman transformation, altering her physical appearance and giving her visions of the future. She was taken in by the other Inhumans and was taken to Afterlife, the Inhuman settlement on Earth, where she used her gift to see several important events before they happened.
