The Guardian's Return 

You know what I just looked it up on the Internet and apparently According to the Internet, the Original Rogue superhero was a mentally unstable Captain Atom Also known as the supervillain Known as Monarch .

Was this story part of the Armageddon 2000 comic series where a time traveler traveled to the future to find out which hero actually went rogue. Because this story in this video is exactly identical to the Armageddon 2000 comic series that came out a few years back. The only difference was , in the comic series, they Never actually discovered which hero had gone rogue . That story went on for a long while but in the end it was inconclusive and absolutely No solid verdict had ever been reached and the rogue hero was Never found .
