Percy Jackson and the Olympians: Legends

Medea is described as being beautiful in a mysterious yet dangerous way, with shadow-dark hair that tumbled over her shoulders, eyes that flickered with knowledge of dark things, and a remorseless detached face that flushed like a girl's when she looked at Jason. She wore a black silk dress, and a golden necklace on which gleamed the symbol of Hecate - two crossed torches. After rising from the Underworld, she seemed to have a faint glow around her. When she got angry, her face would literally glow to the extent where one could see her skull beneath her skin.

Medea is often shown as a vicious psychopath. She displays great ruthlessness and is willing to kill and decieve to achieve what she desires. Medea also shows that she is unable to get over past grudges, Jason's betrayal as a prime example. She displays the mentality that she is never at fault, and that others are always to blame. Medea is an eccentric, cunning and sadistic dark witch who conjures spells to cause harm, inflicting revenge against those who retaliate against Melinoë. She is passionate about making potions with strange effects, even testing them herself. Medea's concoctions make even Melinoë hesitate, as does Medea's constant delight in poisonous air and the abundant bones she collects, eagerly awaiting what will happen.

Medea was the Princess of Colchis, the land that held the Golden Fleece during the time of the original Jason, as well as a powerful sorceress. After the Doors of Death were opened, Medea returned to the land of the living, but was killed again. Having been resurrected once again before the Doors of Death were closed, Medea formed an alliance with Caligula and began plotting to turn him into the new sun god. To this end, she begins summoning the faded Titan Helios out of Tartarus and into a part of the Labyrinth that becomes known as the Burning Maze.
