Deathstroke (DC Comics)

note: Deathstroke is also known as Slade but due to major differences in the characters we have separated them, if you seek information on that particular incarnation of Deathstroke please visit: Slade

Deathstroke is a supervillain from DC comics and one of the world's deadliest assassins, he is also known by the full title of Deathstroke the Terminator and was indeed originally named simply "Terminator" - though Deathstroke was added soon after.

His real name is Slade and it was this name that was used to base the main villain of the cartoon series Teen Titans (although as stated above despite sharing a common name they are different villains).
