Created by a military program to create a super soldier Deathstroke is as much a hunter of humans as an assassin. He has his own twisted sense of honor and sport but makes no illusion to being heroic or anything other than a killer.
He has been an enemy to various incarnations of the Titans and been hunted by governments, but recently has taken to being a hunter for hire. Deathstroke has crossed paths in recent months with Nightwing over the fate of Man-Bat AKA Kirk Langstrom, the brotherhood of the monkey fist, and most recently with Azrael in the question of Caibax's life.
Deathstroke uses a sword as well as various knives and throwing weapons, he also uses sniper equipment and other balistic weapons.
Deathstroke has a powerful healing ability and possible immortality. He is swift and an adept fighter with military training augumenting his metahuman abilities. Deathstroke is a marksman and survivalist with a broad knowledge of martial arts.
Deathstroke may not have any physical weaknesses. Though his depth perception is lessened with the loss of his right eye he has learned to compensate for it. the best strategy is to rely on his still human physiology and hit his pain centers or use gas on him.
