And then there's Bob Bolling's Little Archie (Archie buffs consider him the Carl Barks of the franchise), which is like its own little world; he created Polly Cooper and the South Side Serpents and other concepts/characters that were exclusive to him for decades, and after doing normal kids' stories for a while, Little Archie started going to Mars, capturing foreign spies, and he even got his own arch-enemy, Mad Doctor Doom and his teenage greaser sidekick.

(Mad Doctor Doom and Doctor Doom both first appeared in 1962 and I don't think anyone has ever established who came first.)
