Tales of The Teen Titans #54 (1985)

At Slade Wilson's trial, when it begins to appear as if the Terminator will escape punishment for his crimes, Changeling uses his shape-changing powers to attack Wilson. Subdued by his teammates, Gar Logan is ordered from the courtroom by Judge Adrian Chase. The Teen Titans suspect that someone is posing as the Terminator to make it appear as if the costumed mercenary and Slade Wilson are not one and the same, so they arrange a meeting with Wilson's associate, Wintergreen, only to be attacked by the Terminator impersonator.
