Deathstroke the Terminator first appeared in 1980, in the second issue of the book New Teen Titans. He was originally introduced as “the Terminator”, a mercenary who was completing the terms of a contract undertaken by his son Ravager and later in the series often allied with the Titans against mutual threats.
Due to his popularity, Deathstroke received his own series, Deathstroke the Terminator, in 1991. It was retitled Deathstroke the Hunted for issues #0 and #41-45; and then simply Deathstroke for issues #46-60. The series was cancelled with issue #60. In total, Deathstroke ran for 65 issues (#1-60, plus 4 annuals and a special #0 issue).
