. "Doctor Light"@en . "Doctor Arthur Light is a supervillain appearing in comic books published by DC Comics. He is the third individual to have adopted the persona of Doctor Light, after a Golden Age foe of Doctor Mid-Nite and Arthur's associate Jacob Finlay. Light, a long-time enemy of the Teen Titans and the Justice League, has been portrayed both as a serious menace and as a company in-joke for incompetent supervillains."@en . "Arthur Light"@en . .
