Bloom is the second daughter of King Oritel and Queen Marion of Domino, and the little sister of Daphne, as well as the keeper of the Dragon's Flame, which her older sister passed on to her shortly after her birth. On Earth, Bloom appeared in a building that her adoptive father Mike, a firefighter, was dousing. Mike rescued Bloom and he and his wife Vanessa, a florist, eventually adopted her. Bloom grew up to have an uneventful childhood and had no awareness of her true origins. She and Selina were close friends during their childhood and they used to play together in the Forest of Flowers. In her youth, she received a gift, her pet rabbit Kiko, and met her nemesis, Mitzi.
