Hades, the Greek God of the Underworld, is also known as Aides or Aiidoneus, which means 'the Unseen'. As the God who ruled the dead, Hades has always instilled fear among the mortals as well as the Gods. Born to the Titans Cronus and Rhea, he displayed his valor in the Titanomachy, also known as the 'War of the Titans'.
