Marvel Comics has famously mined Norse mythology for a few of its better known superheroes. However, Marvel has also mined Greek myth, using Hercules as a sometime rival, often good friend, of the mighty Thor. And while Wonder Woman has most famously been pitted against the DC version of Ares, the Greek God of War, Marvel hasn’t been shy about using the character either as a foe of his half-brother the Lion of Olympus.
The biggest difference may be Marvel later turned Ares into a good guy. Mostly.
