Pandora

Pandora (パンドラ, Pandora) is Hades' sister in this life time. She was born at Heinstein Castle as the first daughter of the German noble Heinstein family.

At a young age, while strolling through the castle's park with her dog Adolf, she saw a builiding she never knew of its existence. This derelict building was surrounded by a dead garden, and was shut by a heavy lock. The lock opened itself, and inside this building she found a box with a Seal of Athena. Pandora broke the seal, and the souls of the gods Hypnos and Thanatos were released. She was told that Hades will become her brother and she must protect him until the final battle begins, if she would, they would grant her eternal life. When Hades was born, all lives at Pandora's house began to die except herself.

Then she became Hades' servant, commanding his armies of Specters through the invasion of the Sanctuary during the XX Century Holy War. She is completely loyal to Hades, at the point of being capable of torturing Wyvern Radamanthys when she discovered he had disobeyed Hades' orders and sent Specters to the Sanctuary to watch over the resurrected Gold Saints.

As a result of this servitude, she lost the ability to see fully in color, seeing only shades of gray. Hades gave her a necklace that allows her to travel through different realms (she can travel between the world of the living and the Meikai, and even to Elysion). She has a complex relationship with Ikki due to their past regarding Shun

When the invasion of the Sanctuary failed, she returned to the Underworld. She remained there until the twelve Gold Saints breached the Wailing Wall, and Seiya, Shun, Shiryu and Hyoga crossed the Hyperdimension to Elysion. Pandora confronted Ikki but, after seeing the Phoenix's iron will, she gave him the necklace, which allowed him to travel to Elysion alive. As a result of this, she regained color vision. However, Thanatos saw her as a traitor and used his divine powers to kill her, dying in Ikki's arms.
