Internet Backdraft: Hercules' Ambiguously Bi status being Jossed by Marvel's EIC has rubbed some fans the wrong way. Partially for the fact it meant denying the MU an openly bi male character (which is a very under-represented minority), but also for the fact it goes against the original Greek mythology, where Herc was bi, although it's worth mentioning that the character isn't only bisexual in the Greek myths, but also a pederast among a long list of other dropped traits. Fan reactions have been divided between those who felt that there was a great deal of story potential with a bisexual Hercules and those who felt that the character should be heterosexual a he was for most of his history.
Marty Stu: Amadeus Cho came across this to many readers when he was first created thanks to showing up fellow super-geniuses Reed Richards and Tony Stark. Toned down and became a more balanced character later in the series debatable if he retained traits of this.
Mary Sue: 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 Fandom Nod to Cho's reputation in Chaos War #5.
Memetic Badass: Hercules himself is widely agreed upon as being one of the most badass characters in the Marvel Universe. In fact him gaining this reputation after Civil War ended up earning him some stand-alone books of his own after years of toiling in obscurity.
Zeus is also getting this status. Not really surprising since he gave the freaking Hulk a brutal beating.
Memetic Mutation: 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.
Strawman Has a Point: Amaterasu was a bitch for wanting to save the gods at the expense of Earth, but she was completely justified in her harsh actions. The mortal world had already fallen and she was trying to protect the heavens and what was left of the universe from a suicide attack that had no hope of succeeding. She was proven right when Hercules in his stupidity opened up a gateway to the heavens allowing Mikaboshi to invade and casually destroy all of the gods. The Aesop of mortal heroes being better then gods falls apart since all of the gods actions were necessary and Hercules's stupidity constantly made things worse even in recreating the world.
Hercules revealing why he uses the Roman version of his birth name, Heracles. 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. You could argue that this makes Herc The Atoner.
Win the Crowd: Turning over one of Marvel's flagship titles to a B lister Thor wannabe? Turned out pretty well.
