Onyx Equinox is a Mexican-American adult animated streaming television series created by Sofia Alexander for Crunchyroll. It is based on the mythologies of Mesoamerica, featuring deities of Aztec, Maya and Zapotec myth, while also making references to the Olmecs.

The series premiered on November 21, 2020. Alexander said that she hoped that fans of Western animation would "see the appeal of action-drama animation for adults." While Alexander was initially nervous about pitching the show due to the lack of "stories about Mesoamerica," a Crunchyroll executive, Marisa Balkus, loved the pitch, and the show became "the first original series to be produced entirely out of Crunchyroll Studios."

Onyx Equinox

Synopsis

The Mexican god of the underworld, Mictlantecuhtli, has begun stealing blood sacrifices from the other gods, culminating in a Zapotec city being leveled. To these ends, Quetzalcoatl decides to close the gates to the underworld, but can't due to said gates being made of obsidian, which is toxic against the gods. So instead he makes a bet with Tezcatlipoca: he will find a human, "the lowest of the low", and crown him his champion so he will close the gates before the equinox, when Tezcatlipoca will kill off humanity. Tezcatlipoca agrees to the bet, but sends his champion Yaotl along as an emissary so Quetzalcoatl doesn't cheat.

Quetzalcoatl chooses Izel, a slave who lost his sister to blood sacrifice.

Episodes

Release

The show was released on November 21, 2020. A trailer was released on June 25. A second trailer showing off the show's characters was released on September 4, 2020, with a final trailer on October 29. On November 11, 2020, Crunchyroll announced that the series would be dubbed in English, Spanish, Portuguese, French, and German upon release. Crunchyroll released the remaining seven episodes of the series on December 26, 2020 due to a high demand of viewers wanting to binge the series rather than waiting weekly for new episodes through February 2021.

On May 18, 2021, it was announced Sentai Filmworks picked up the home video rights. It was released on Blu-ray on February 22, 2022 as Onyx Equinox Complete Collection.

In January 2022, Alexander revealed that the budget of Onyx Equinox was "near 1/3 of a lot of western shows" and said a main reason they unionized was because she "threatened to leave before production started." She also said that she was grateful to Crunchyroll because she wouldn't have been able to have a story about grief and trauma and have LGBTQ characters on other platforms.

In May 2023, Alexander reported that Crunchyroll couldn't find production assets for episodes 4-12 of the series because of "how they archived it" and said she never made copies because "it wasn’t allowed."

Awards

In early December 2020, Onyx Equinox creator Sofia Alexander received Animation Magazine's "New Voice of the Year" award.
