Who are is Hades Rivals?

Hades, the Greek god of the underworld, has several rivals, most notably Zeus and Poseidon, his brothers who rule the sky and the sea, respectively. Their rivalry stems from the division of the cosmos after the defeat of the Titans, where Hades received the underworld, a domain he often viewed as lesser. Additionally, figures like Persephone, whom Hades abducted, can be seen as rivals due to the tensions surrounding her annual return to the surface world. Other mythological figures, such as Hercules and Theseus, also challenge Hades in various myths, often seeking to rescue souls from his realm.
