When I was a kid, I considered Doctor Light to be one of the main villains of the DCU. Like Doctor Doom over at Marvel, he did not seem to be tied to one particular hero or team and indeed was a menace all over the company's roster of titles. He showed up as an antagonist in many different heroes titles, not to mention taking them on as groups in the pages of Justice League of America or Teen Titans. Maybe he wasn't able to maintain his standing as an arch villain because he was defeated so often.
