Diomedes

Diomedes was one of ancient Greece's fiercest warriors and played a significant part in the fall of Troy, probably more so than Achilles, who was absent for most of the time after falling out with Agamemnon over Briseis. Before the battle for Troy, he had avenged his father, who had, with the Seven Against Thebes, failed to take the city. Diomedes, along with the Epigoni, the sons of the seven, succeeded where their fathers had failed.'He fights with rage and fills men's souls with dread. I hold him greatest of them all; we did not fear even their great champion Achilles, son of an immortal though he be, as we do this man: his rage is beyond all bounds, and there is none can vie with him in prowess."(Hector's brother Helenus describing Diomedes. The Iliad Book VI)
