Tormina is the daughter of Death Queen and as such the sister of Lady Death. Although standing by her mother's side, she is rebellious in nature and tries to sabotage her mother's actions. When Death Queen saw no more use in Tormina, she 'killed' her. In reality, Tormina had teleported herself to safety, letting her mother believe she was dead.
Since the destruction of Death Queen, and Lady Death's 7 year disappearance into the Void, Tormina was left alone to rule the realm as Queen Tormina.
She has the power to dampen magical and physical powers of other people. She also has the ability of teleportation, but she can only teleport herself.
