The evil Supermen are the most popular characters in their respective franchises despite the horrific things they've done and the fact that they aren't the main characters. Omni-man and Homelander both basically eclipsed the other characters from the series they're from and are easily the shining star of the featured series with some saying Homelander basically caries The Boys tv show. Meanwhile Clark seems to always be struggling for top billing in his respective ventures and has spent the past couple decades getting his material stolen piece by piece.
