That's where he's first mentioned when Eternity is talking to Dr. Strange about The Living Tribunal. Maybe I should have notated that as a "First mentioned" instead of a first appearance, since he didn't physically appear in that issue. But it's always been my understanding that Dr. Strange 13 was his first Marvel appearance. Feel free to revert my edit if you disagree! :-)
