Always Save the Girl: Double-Subverted. Hades offers a deal for Hercules to give up his strength for 24 hours in exchange for Megara's freedom and to promise that she will be safe from harm. He's aware that Hades plans to do something nasty but Hades pressures him into it.
Badass: As always, Hercules is the primer monster buster.
Berserk Button: He gets one near the end; he's put up with a lot of crap during the last half of the film, but seeing Hades dare to lay his filthy mitts on Meg after nearly getting them both killed finally sends our hero over the edge...and Hades also, literally.
Happily Adopted: His mortal parents really love him and Hercules seems to accept both his earthly and heavenly parents as legit. One song about mid-way through the movie shows that he's using his newfound fame to take gooood care of them, building them an enormous mansion.
Heroic Build: Initially no but training under Phil fixed that.
Wonder Child: His adoptive parents have been praying to the gods for a child. When they find the baby Hercules, with the symbol of the gods on a medal around his neck, they naturally assume the gods sent him to them. He is, of course, actually a god made near-mortal.
World's Strongest Man: Phil's students are the strongest there is and Hercules is the strongest of them all.

Anti-Villain: She's one of Hades' minions but only because she sold her soul to him to save her ex-boyfriend's life.
Composite Character: She has the name of Heracles' first wife, and yet her run in with the Centaur Nessus comes from his third wife Deianira.
Contralto of Danger: Megara has a sultry, husky voice, atypical of both Disney female Love Interests in general and female characters in the movie. She's also working for Hades (albeit unwillingly), and at one point tries to seduce Herc into revealing his weaknesses, though she just ends up falling for him instead.
Meg: My friends call me Meg. At least they would if I had any friends.
Freudian Excuse: She sold her soul to Hades to save her boyfriend's life. Said boyfriend promptly abandoned her for another girl, resulting in her putting up a snarky Ice Queen exterior to avoid getting hurt again.
Non-Standard Character Design: Due to Gerald Scarfe being the main stylistic influence on Hercules, she stands out from other Disney heroines with her stylized design (including an impossibly small waist).
Take a Third Option: Between having Hercules depowered to save her or being wounded if Hercules breaks the pact that ensures her safety? She'd rather break said pact herself via saving Hercules from a falling column, even if it's at the ultimate cost of her life.
Tsundere: "I Won't Say I'm In Love" demonstrates it best.
No chance! No way! I won't say it!—>At least out loud....I won't say I'm in....love....
Casanova Wannabe: The various humans and nymphs run away from his advances yet he insists they "can't keep their hands off me." That gets him slapped.
Averted though, as women on Earth reject him. But in the end of the film, Aphrodite-the Goddess of love of all people falls for him, giving him a passionate kiss instantly, and having to be pried away from her by Hercules, who's flying back home with Meg.
Good Parents: Both are very supportive and loving to their adopted son, Hercules.
Happily Married: Even though their scenes together are short, we still see them as a happy couple.
Rags to Royalty: Downplayed. They weren't necessarily poor, but still of a working class couple. When their son made it big in Athens, they become rich. Even so, they are still seen with their old home and Penelope thus implying that even with being rich, they still wanted to have some of their old lifestyle.

A God Am I: Granted, he already is one, but his goal is to become the god and supreme leader of Mt. Olympus.
Big Bad: He's gathering an army so he can take over Olympus.
Breakout Character: Despite having no redeeming qualities whatsoever, James Woods' spirited portrayal of him made Hades one of the most iconic and popular Disney villains.
Woods himself loves the character so much that he goes out of his way to ensure that he ALWAYS voices him, even if it means not being paid much (hence why Disney managed to get him in every episode of the tv series he appeared in, which was all but a few of them).
Didn't See That Coming: Both the Fates and he expected Hercules to die when he jumped into the Well of Souls to save Meg. However this self-sacrifice turned out to be the final requirement to regain his God-hood.
Dragged Off to Hell: Well further to Hell as Hercules punches him into the Well of Souls where the spirits drag him down.
Everybody Hates Hades: His entrance at Hercules' birthday party is met with scowls and his domain is treated more like the Christian idea of Hell than the Greek afterlife. This holds a grain of truth; while real life Greeks and the gods never hated Hades like we see in the film, he was definitely not treated with as much respect as the other gods.
Evil Is Not a Toy: Averted. He releases the Titans so they'll help him in his conquest. They never betray him because he's their brother and they are united by their hatred of Zeus. Played straight with Hades himself though. Any time you make a deal with him, or get him to help you, he'll screw you over one way or another.
Evil Is Petty: One infamous scene has him throwing a tantrum over Pain and Panic wearing Hercules themed merchandise.
Evil Overlord: "He ruled the underworld... but thought the dead were dull and uncouth. He was as mean as he was ruthless...."
Manipulative Bastard: He charms The Fates into revealing the future, twists Hercules' arm into giving up his strength and then appeals to both brotherly love and old hatred to get the Titans on hs side.
Physical God: He's made of smoke and flames and something else. He's the lord of the dead.
Pragmatic Villainy: This is shown in a crossover with Aladdin where he's not shown obsessing over revenge against him for beating Pain and Panic. His response to Jafar explains why he's not looking for revenge:
Hades: Uh yeah sure. How bout I rule the cosmos first and then I'll take it.
Surrounded by Idiots: Pain and Panic are incompetent and Meg only helps under duress (soul ownership) so he ultimately has to do everything himself.
Technicolor Fire: Normally blue, goes red and orange when angry (in reality blue flames are hotter than red\orange ones, but...).
This Cannot Be!: When Hercules emerges from the Well of Souls with both Meg's spirit and his regained God-hood.
Villain Ball: He only intervenes personally when it's directly needed. Other than that he suffices with watching from above and not questioning his minions, which needless to say backfires on him.
Villainous Breakdown: He gets these (and then recovers from them) regularly because of Hercules killing his monsters and then finding ways to exploit this. Least till the end of the film when Hercules regains his godhood, depriving him of his revenge.
Villainous Crush: In the show and hinted in the movie, he has a crush on Aphrodite.
Villainous Incest: It's never established if he and Aphrodite are related in some way. However, some legends say that Aphrodite's father is Zeus.
Dirty Cowards: Played with. They sneak into the palace of the King of the Gods and steal his kid all the while bemoaning that he's gonna use them for 'target practice' yet they still did it. This is because they fear their boss more.
The Dragons: Hades always summons them which implies they're the head imps.
Sadly Mythtaken: There were nine muses in Greek Mythology. There are only five here. Also, why would Greek Goddesses be singing gospel?Rule of Cool can explain the latter (It's a Disney film; they gotta fit a musical in there somewhere) but not the former.
Static Character: Out of all the Muses, only Calliope and Thalia have a major role. Although Melpomene (the Muse of Tragedy) did get a solo during one of the "Gospel Truth" songs. Terpsichore gets a major role in one of the tv show episodes.
The Fates (Clotho, Lachesis and Atropos)
Voiced by: Amanda Plummer, Carole Shelley and Paddi Edwards
Ascended Extras: They start out as Advertised Extras, since the trailers imply that they appear far more often than they do in the actual film (though they do play a major role nonetheless). However, they are upgraded to recurring villains in the TV series.
Affably Evil: They're fairly polite, for a group of scary old hags. Clotho in particular seems to be the most cooperative of the trio.
Blind Seers: Kind of. They have one eye between them so two of them are blind at any given time.
Terrible Trio: The three of them cut, spin, stretch and cut the strings of life.
Villainous Crush/Abhorrent Admirer: Atropos to Hercules in the TV series. Clotho could be seen as the latternote Obviously she can't be the former, since they're both villains toward Hades too, which is something he exploits to get her to tell him the future.
Abusive Precursors: The opening song states that before the Olympians ruled, the Titans were the gods in charge, and they made Earth a nasty place to live.
Four Is Death: Downplayed; four of them are depicted as having a major part, but there's actually five of the; one of them is a cyclops.
Kaijus: They're all huge malevolent monsters that attack cities.
Lean and Mean: Averted with Hydros. He/It's thinner than the other titans but no more or less mean.
Obliviously Evil: It's implied that they're simply extremely powerful forces of nature who just happen to have a target (Zeus) or a lack of one in the prologue (thus "everywhere").
Sealed Evil in a Can: Zeus imprisons them all beneath the ocean with lightning bolts, but when the planets align, Hades is able to release them. Hercules uses the Tornado Titan to suck the other Titans in, then throws them all into space where they explode.

Abhorrent Admirer: To Cassandra. She regards him as a nuisance. Granted, he is brain damaged, so it's somewhat difficult for him to take a hint.
Adaptive Ability: He can adjust to just about anything, even Spartan military training!
