Fidi

Fidi is the son of Medusa, and the High Deity, Hades. He was left at the house of Hecate and Morpheus, who had left Olympus, where he was raised with their twin Daughters, Notte and Matin. Fidi's capable of entering a stage of pure Rage and Wrath known as his Demon State, or Underworld Wrath. He's almost always quiet and respectful, being mentally beaten down from the suffering inflict upon him, due to being half Naga.
