A Greek Assassin and an antagonist to the Green Arrow.

Constantine Drakon, despite his relatively small amount of appearances, has nonetheless made quite a name for himself, particularly among the members of the Arrow family. Initially confronting Green Arrow and the others when contracted to kill monsters plaguing Star City, Drakon proves to be more than a match for the elder Green Arrow, and the Greek stabs the Emerald Archer through both hands with his own arrows. Later, Drakon came into contact with Connor Hawke while the former was searching for papers that would connect his employers to the monsters. While considered a formidable opponent in his own right, Connor was devastated by Drakon's martial onslaught, but managed to escape from the assassin through the aid of Speedy.

Abilities:

Constantine Drakon is an incredibly skilled martial artist, and is also a formidable gunman and knife-thrower, and was, in fact, able to throw a knife into one of his employer's shoulders so fast that no one even noticed he had moved. He has also proved capable of catching multiple arrows fired by skilled opponents without any real exertion.
