Adam gets it! Lock-Up appeared on Batman: The Animated Series before appearing in the comics (in fact, Lock-Up appeared in the comics before Harley Quinn did!). Another one I would have accepted was the Condiment King.

All yours, Adam.

Who, upon teaming up with Burger King, let people have it their way.

Your Avatar is missing.

Question: What actor has played a Silver Age Atom villain in a live-action movie, the villainous father of a major DCU villain on a long running tv series and voiced a popular Bat-villain on an animated series?

Missing or merely invisible to those not trained in supernatural arts?

That middle condition is intriguing.

I don't know, but I'll guess Mark Hammill.

"Missing" as in a red x located where an image is suppose to be.

A very good guess but, no.

Well, I only know of one Silver-Age Atom villain who's been in a movie, but I don't recall who played him and I won't violate my own rule against looking it up.

I thought that was the rule everyone is supposed to have? Did the ACLU invade the thread or something?

I'd almost think the villain was Giganta, considering she was engaged to the Atom on that live-action "Super Hero Roast.

The only person I can think of whose done live action and voice over work with Superhero types is Miguel Ferrer.

Some very good and in one case obscure answers but, alas, no.

I can't recall if this is the actor I'm thinking of, but how about John Glover?

--he was the Devil on a show called "Brimstone."

Damn, Wyld beat me to it! John Glover came to my alma mater last year to speak with the young actors in training.

I know he played Jason Woodrue, the Floronic Man in a Batman movie and he was Lex Luthor's father in Smallville, but I'm not sure which bat villain he voiced.

Yep And extras kudos to you for bringing up one of my fav series, Brimstone. An excellent and much-too short lived series. John Glover played Jason Woodrue in Batman & Robin, he played Lionel Luthor father of Lex on Smallville and he was the voice of The Riddler on Batman: The Animated Series.
On to you, Wyld!
