Short answer: it depends on the arena. Heracles, son of Zeus and a mortal woman, is the endurance pick: the twelve labors were a years-long campaign against monsters, and he once held up the entire sky so Atlas could run an errand. Thor is the raw-output pick: better gear, heavier single hits, and a giant-slaying day job he never called in sick for. Versatility and stamina, Greece. Peak power and equipment, Asgard. Pick the scenario, then pick your strongman.
The tale of the tape
| Category | Heracles | Thor |
|---|---|---|
| Parentage | Zeus + a mortal (demigod on hard mode) | Son of Odin and the earth itself |
| Signature weapon | Club, bow, and the Nemean lion's skin | Mjolnir, plus iron gloves and a belt of strength |
| Greatest feat | Twelve labors, including holding the sky for Atlas | Drank from a horn secretly plugged into the ocean and moved the tides |
| Serpent record | Beat the Hydra (with help on the heads) | Nearly lifted the Midgard Serpent disguised as a cat |
| Fatal flaw | Rage, and terrible taste in shirts | Rage, and a serpent-shaped destiny |
| Ending | Poisoned by the shirt of Nessus, then promoted to full god on Olympus | Kills Jormungandr at Ragnarok, walks nine steps, and falls |
Same job, different pantheon
Strip the names and the resumes rhyme. Both are their pantheon's designated muscle, kept around to punch whatever nobody else can. Both have anger management issues with real casualty counts. Both fight giant serpents: Heracles seared the Hydra's necks shut (see where she places in our Greek monsters ranking) and dragged Cerberus into daylight bare-handed, while Thor's rematch with Jormungandr is booked for the end of the world. And each has a famous cross-dressing episode: Heracles spent three years serving queen Omphale in women's clothes, and Thor wore a bridal veil to crash his own fake wedding and take Mjolnir back, with Loki as the bridesmaid. For the fully divine tier of this argument, see Zeus vs Thor vs Ra.
Quick questions
Is Hercules the same as Heracles?
Yes. Hercules is simply the Roman name for the same hero: same labors, same club, same terrible temper. The Greek sources say Heracles, "glory of Hera", which is ironic, since Hera spent his entire life trying to kill him.
Could Heracles lift Mjolnir?
Almost certainly. The worthiness clause is a Marvel rule, not a Norse one: in the myths, Mjolnir demands iron gloves and a belt of strength, not virtue. A man who held the sky for Atlas is not going to be stopped by a short handle.
Who actually dies better?
Thor's death saves the world: at Ragnarok he kills Jormungandr, walks nine steps, and falls to its venom. Heracles' death wins him a promotion: the poisoned shirt of Nessus sends him to the pyre, the fire burns off his mortal half, and he ascends to Olympus as a full god, the only mortal ever to earn it. One dies a savior; the other dies upward.
