Pandora

She reincarnates in every era Hades has to resurrect, choosing a mortal host suitable for her master's might and acting as his lieutenant and the commander of the Specters. In Lost Canvas she is depicted as being so attached to Hades to the point of hysteria and paranoia (Hades defined himself "a bird in a cage"); nevertheless she is a merciless and loyal servant of the god of the Underworld. She used to be a pawn of Hypnos and Thanatos' (whom she was frightened by) schemes, which often put her against her own beliefs and wishes, prompting her to seal Hades away so as to keep him focused on painting the Lost Canvas. Pandora is crushed upon learning that it had been Alone, not Hades, who had been at her side since they met. With her heart full of sorrow, she departs to find the true Hades, and to punish Alone, whom she hates. She last appeared mobilizing Hades' army, after the defeat of Bennu Kagaho, later, she is enraged by Harpy Valentine's defiance, and aiming to break his will by means of torture, she performs her Noble Venom technique on him, which induces excruciating pain. Her attack is negated by the Specter and she is then the victim of his attack; however, she manages to break free and overwhelm Valentine, who is later punished by Rhadamanthys.
