who had hired him as an assassin. Slade refused, claiming it was against his personal honor code. He attacked and killed the kidnappers at the rendezvous. Unfortunately, Joseph's throat was slashed by one of the criminals before Slade could prevent it, destroying Joseph's vocal cords and rendering him mute. After taking Joseph to the hospital, Adeline was enraged at his endangerment of her son and tried to kill Slade by shooting him, but only managed to destroy his right eye. Afterwards, his confidence in his physical abilities was such that he made no secret of his impaired vision, marked by his mask which has a black, featureless half covering his lost right eye.

The Teen Titans Slade has a long history as an enemy of the Teen Titans, beginning when his other son Grant received superhuman enhancements from the H.I.V.E., dubbed himself Ravager, and accepted a contract from them to kill or capture the Teen Titans. However, Grant's enhancements proved fatal, and Slade agreed to complete the contract. His first mission involved stealing the element Promethium from S.T.A.R. Labs and selling it as the ultimate weapon. He then kidnapped the Titans and placed them in the path of a Promethium bomb to test his device for the buyers, effectively killing two birds with one stone.

Terra knocked Beast Boy out and fought Deathstroke single-handedly in an effort to prove herself worthy of being a Titan. Deathstroke escaped as the other Titans arrived, but by then Terra had proven herself and the team offered her membership.
