Medea is Eden's mother and Mars's wife, being one of his High Martians.
Medea is presented as a very quiet woman who appears entirely loyal to her lord Mars from her first appearance, merely talking when needed.
However, this is a facade and Medea is in fact a power-hungry, coldhearted and manipulative individual. She would use and betray anybody for her plans to succeed and has done this even to those who have put their utmost trust on her without any remorse whatsoever.
Medea is also responsible for triggering most of the main event in Saint Seiya Omega:
In the battle between Athena and Mars, Medea summons a meteorite composed of darkness that causes every Saint to get elemental powers. She and her brother Amor intended to use the war god to fuse his and Koga's Darkness Cosmo to awaken their true master Abzu.
