Perhaps the greatest fiends of Charlton and MLJ didn't start out as such. And yet, each became consumed in his own success and dreams of conquest, albeit not on purpose. Honest!
When DC Comics attempted to craft an epic crossover throughout its various series, a new supervillain named Monarch appeared. A vile tyrant of the year 2030 who found his start in 1991, the one thing known about him was that he was a former superhero.
Although originally intended to be Captain Atom adopting this new alias, he was revealed to be another hero known as Hawk. However, Atom eventually adopted this identity after several time traveling machinations of the original, although his criminal career was relatively short and didn't taint his lasting legacy as a larger-than-life legend.
When MLJ Comics tried various means to brand their flagship series Pep a success, a comical lad named Archie introduced his readers to a world of teenage comics from which he would henchforth be king from which other publishers would aspire to imitate.
However, the side effect of this success led to the fall of costumed crusaders such as the Shield and Hangman, who once held sway over their small but significant share of readers. So, in essence, Archie ended up doing what several foes like the Hun and Captain Swastika couldn't... vanquish the underwear set... banishing them into comicbook limbo from which they would not return for nearly twenty years!
