[[WMG: Icarus (and maybe even Daedalus) is the enbodiment of Jealousy (and possibly even Lust)]]
[[DontExplainTheJoke Self-explanatory]].

[[WMG: The whole movie is historical revisionism by Zeus himself.]]

In some stories the end of the Age of Heroes (specifically the Trojan War) was engineered by Zeus to get rid of his illegitimate children, so it's not like this is beneath him. Zeus overthrowing the Titans in the backstory is portrayed as unambiguously good when in the original myth it brought about the end of the Golden Age. The Titans are portrayed as inhuman forces of nature instead of being more or less the same as the Olympians. Hercules is now Hera's child, which eliminates the cheating Zeus part of the story. Since that would mean Hercules is all god we need a reason for him to not be in Olympus, hence the kidnapping and the "you need to become a true hero" BS. Since it wouldn't make sense for his own mother to be his enemy, Hera gets replaced with Hades, who can't exactly leave the underworld to give his side of the story. Hades also replaces Gaia in the Titan rebellion story to cover up the complicated relationship between the Olympians and their ancestors.
* Continuing on this theory, this is Zeus' attempt to survive in the Christian era. Thus why it's HijackedByJesus: partly to fit in with conservatives, and partly to enter the wonderful and powerful world of Disney. One wonders how painful it would be for him to fit in [[ValuesDissonance with the radical change in values.]]
* The Muses are helping him, or rather, ''five'' of them are. They're the ones telling this story, they interupt the narrator, and assure the audience [[SuspiciouslySpecificDenial several times]] that what they speak is the "Gospel Truth".
* Alternatively, the movie is canon and the "original" Greek myths where lies spun by Hades as a petty way of revenge. Surely it is not coincidence that in the original myth's Zeus was a dick and Hades was more reasonable.

[[WMG: Megara has more issues in her life than what's revealed in the movie]]
It's implied that she's had some not so great experiences with dudes who won't take no for an answer. "They think NoMeansYes, and 'get lost' means 'take me I'm yours'."
** You see Hades getting up close to Meg and invading her personal space a couple of times, which she's clearly uncomfortable with. ''He'' was one of the guys who didn't take no for an answer.

[[WMG: Meg selling her soul made her invulnerable - AND immortal]]
* She sold her soul to Hades. He's always losing his temper so, like Pain and Panic, she is in some way immune to his flames. She dodges because, like them, burning hurts her. Heckaroonies, Hades blows the top off a mountain at one point and she doesn't get a scratch.
* On the second part, after selling her soul to Hades, she had been alive for years at the same age, which also added to her embitterment - and that Pain and Panic were in a similar situation. Anyway, as soon as she got her soul back, she was mortal again. Immortality is clearly not so great when you're gonna spend it in enslavement to a JerkAss.

[[WMG: The film was originally planned to have Typhon as the monster unleashed by Hades, and Ares would have been the BigBad.]]
Consider this: in the original myths, Typhon was one of the few monsters that scares Zeus, and Ares' two minions, Phobos and Daemos, were repurposed into [[ThoseTwoBadGuys Pain and Panic]]. The inner mythology buff would have loved the film even more if this is how it ended up - Typhon could be the biggest example of Nightmare Fuel in a Disney film since [[Disney/TheLittleMermaid Ursula]], and it would have been fucking metal.

[[WMG: The filmmakers were fans of ''DungeonsAndDragons''.]]
Because the Titans are totally Ogrémoch, Yan-C-Bin, Cryonax and Imix.

[[WMG: Zeus put Persephone in charge of the Underworld.]]
Zeus needed someone to run the Underworld, but couldn't just let Hades go. So he asks Persephone to do it, since it's not like she's doing anything during Winter anyway.

[[WMG: Meg is much older than Hercules.]]
When they first meet, Meg calls Hercules "junior", which suggests she's notably older than him. At that point, Hercules must be something like 16 or 17; the time difference between the beginning of the movie (where Hercules is a baby) and the finale is said to be 18 years, and the heroic tasks and fame-building Hercules does between the first meeting with Meg and the finale must've taken him at least a year. Meg, on the other hand, is portrayed as an adult woman right from the start. She doesn't talk or act like a teenager, and her mannerisms and voice are much more mature than Hercules'. Also, she has already been in an adult relationship with a guy, the one for whom she sold her soul to Hades. The familiar tone with which Hades and Meg talk to each other suggests that their deal has been going on for quite some time already, it's not something that happened in the recent past. Now, all this information implies Meg is about 10 years older than Hercules; she's probably in her late twenties or early thirties.

There's nothing ''wrong'' with this age difference. On the contrary, it's refreshing to see a couple in a Hollywood movie who's age difference goes this way, instead of the usual older guy/younger woman pairing.
* In the seriers because Meg appears as NewTransferStudent at Herc's school but this can explained as her staying the same age physically.

[[WMG: The prophecy about Hercules defeating Hades was self-fulfilling.]]
Since Hades was trying to recruit the river centaur for what he claims is his assault on Mt. Olympus, presumably all the other monsters that Hades had at his disposal would've been used for attacking Mt. Olympus, in addition to the Titans. Hercules had little trouble killing them in one-on-one combat, but if he had to face them all at the same time at Mt. Olympus, he wouldn't have stood a chance.
