Percy Jackson and the Olympians: Legends

Melinoë has heterochromia with one eye red like her father's and the other green like her mother's. Her left arm appears spectral with a supernatural green glow, revealing her skeleton that can be seen within it. Her hair is wheat blonde like her mother's, the haircut is short and does not share the spiky characteristics. In the hot spring, her hair gains more body and waves than when it is dry. Her skin is pale like her brother's, but she is slender and less muscular than him, and like her father and brother, her bare feet glow with warmth. Melinoë adorns her head with a laurel wreath that glows like embers when on her head, similar to her brother's. Parting her bangs at the center is an upward-facing crescent moon on her forehead. She wears a short saffron-colored dress fastened up to the neck brace, with her limbs adorned with metal ornaments, including lunar shapes on her right leg. On her left leg, Melinoë wears a braided cord in the colors of orange, green, blue, and black.

Melinoë is enigmatic and introspective, often lost in thought. She possesses a deep empathy for the suffering of others and is driven by a desire to help those in despair. Despite her somber nature, she has a playful side that emerges in moments of joy.

Melinoë, Princess of the Underworld, is the daughter of Hades and Persephone. While Melinoë's family lived a happy life in the underworld, the titan Kronos broke free from his prison deep in Tartarus and took control of the Underworld. On her father's orders, Hecate took Melinoë and trained her to be a titan slayer.
