Nothing much is known about the past of Constantine Drakon. At some point in his life, he was hired as a bodyguard by Adam Hunt and became the head of security. When Arrow threatened his boss, Drakon put a team together to protect Hunt but Arrow killed the whole team. It was Constantine who was almost a match for the vigilante and nearly killed the vigilante with a bullet but Arrow survived the attack and killed Drakon with an arrow to the chest.
