Deathstroke is Slade Wilson, the world's greatest assassin/mercenary and an enemy of the Teen Titans and the Justice League. Originally a soldier in the U.S. Army, he was part of an experimental super-soldier project where he gained enhanced strength, agility and intelligence. His vendetta against the Titans began when he swore revenge for the death of his oldest son Grant; his two other children would go on to become Titans members as Jericho and Ravager. Traditionally his actions have been limited by a strong personal code of honor, although his motives became more villainous following the death of his wife Adeline Kane. Through this time his only steady companion is his loyal manservant Major Wintergreen. He has been a member of Checkmate, H.I.V.E., the Injustice League, the Secret Society of Super-Villains, the Suicide Squad, the Titans, and Titans East. Deathstroke was created by Marv Wolfman and George Pérez, first appearing in New Teen Titans #2 (1980).
