Ajax is a renowned Greek warrior, said only to be excelled by Achilles, and the son of the king of Salamis. In Fall of the Trident, he meets Arkantos during the Trojan War and afterwards stays with him for the rest of his adventure. In The New Atlantis, Ajax is sent leading a company of Greek troops to confront Kastor and the Atlanteans because of their unexplained attack against Sikyos, but joins Kastor after realizing that he had been tricked by Kronos' servant.
Ajax wields a shield and spear. His special attack is a shield bash that knocks enemy foot soldiers back a short distance. He is the Archaic Age hero for Hades, though he doesn't have his special attack.
