* EvilIsSexy: Lampshaded with Alflyse, Dark Elf Queen of the Eastern Spires.
--> '''Zeus''': "Are the wickedest queens always the comeliest?"
--> '''Hercules''': "Usually."
* MartyStu: Amadeus Cho came across this to many readers when he was first created thanks to showing up fellow super-geniuses [[ComicBook/FantasticFour Reed Richards]] and [[IronMan Tony Stark]]. Toned down and became a more balanced character later in the series debatable if he retained traits of this.
* MarySue: You'll often hear criticism of Amadeus Cho for being one of these; he had his moments starting out, but by the end of the first arc he's a well-rounded character.
** There's a FandomNod to Cho's reputation in ''Chaos War'' #5.
* MemeticMutation: See the page image. Herc has become the poster boy of that one meme.
** Said image is also popular with the "Do it, faggot" meme.
* MoralEventHorizon: [[spoiler:Athena]] crossed it at the end of the series.
** [[spoiler:What happens when Amadeus finds the real Kirby.]]
** The end of "Assault On New Olympus".
** Hercules revealing why he uses the Roman version of his birth name, Heracles. [[spoiler: If you add in what Hera reveals at the end of the earlier ''New Labors Of Hercules'' miniseries, that the murder of Herc's family really was all her fault, it becomes more powerful - Herc wasn't to blame, but he continues to accept blame anyhow. [[AlternateCharacterInterpretation You could argue]] that this makes Herc TheAtoner.]]
* WinTheCrowd: Turning over one of Marvel's flagship titles to a B lister Thor wannabe? Turned out pretty well.
* TheWoobie: Hebe, long-suffering Hebe.
