Hades (also sometimes Pluto or Hell) is a fictional character appearing in DC Comics publications and related media, commonly as an adversary and sometimes-ally of the superhero Wonder Woman. Based upon the eponymous Greek mythological figure, he is the Olympian god of the dead and ruler of the underworld.

Hades has appeared in various media outside comics, primarily in association with Wonder Woman. John Rhys-Davies, Bob Joles, and Oliver Platt have voiced the character in animated series and films.

Hades first appeared under his Roman name Pluto in Wonder Woman #16 published in the summer of 1946, written by Wonder Woman creator William Moulton Marston. In this story, he kidnaps women from Earth, using them to decorate his castle on the planet Pluto, before being defeated by Wonder Woman and her allies. He would next encounter Wonder Woman in a 1962 Silver Age adventure in issue #131 of her monthly title, in which the hero ventures underground into Hades (referred to in-story as "the Underworld") at the behest of her mother Hippolyta, battling Cerberus along the way and cannily avoiding a skirmish with Pluto's ghostly subjects. In 1978's Adventure Comics #460, Wonder Woman once again undertakes a journey to Pluto's realm (referred to both as "the Land of the Dead" and "Hell") to retrieve Steve Trevor's soul. Here, Pluto is depicted with Mephistophelian features, including devil horns and red skin.

in Wonder Woman #329, the character is renamed Hades as part of writer Mindy Newell's move to standardize the use of Greek names for DC's Olympian pantheon. He is re-introduced as a more benevolent character, again named Hades, in writer/artist George Pérez's post-Crisis reboot of the Wonder Woman mythos in 1987. Yet another version of the character would debut in 2011 as part of DC Comics’ New 52 publication event, which again revised Wonder Woman’s continuity. This incarnation, referred to primarily as Hell and sometimes as Hades, presents the character not as an adult man, but as a young boy in black and red armor whose head is crowned with melting candles.

As in classical mythology, Hades is a member of the Olympian gods, the immortal children of the Titans Cronus and Rhea. Along with his brothers Zeus and Poseidon, he ruled a significant portion of the ancient world. As the god of the Underworld, Hades had dominion over the spirits of the dead. His realm was divided into four sub-sections: Tartarus (abode of the damned), the Asphodel Fields (a misty after-world), the Elysian Fields (where the righteous dwell) and the Isle of the Blessed (the paradisal resting place of those deemed great heroes). Hades rules these realms with his niece and queen Persephone.

Hades does not figure frequently in the adventures of Wonder Woman until the end of the first volume, when the Anti-Monitor tricks him into making a pact with Ares to conquer Olympus. The plot is thwarted when Persephone (referred to in-story as Kore), inspired by the love between Wonder Woman and Steve Trevor, confesses her love for Hades. Hades pulls out of the scheme and Trevor frees the gods while Wonder Woman battles Ares.

Due to Darkseid's manipulation, the Olympian gods are split into separate entities for many years, existing as both their Greek and Roman variations. Hades' Roman counterpart Pluto rules his own dimensional variant of the Underworld, occasionally coming into conflict with his "brother". The pantheons eventually rejoin more centuries later.

Hades once collaborated with Ares and Anti-Monitor in their attack on Mount Olympus and the Amazons. Wonder Woman helped to repel the attacks.
