Rivals of Aether is a platform fighter game created by Dan Fornace, and released for Microsoft Windows in March 2017, for Xbox One in August 2017, and for Nintendo Switch in September 2020.

[7] On January 17, 2018, Maypul and Ranno received crossover skins based on the characters Ragnir and Wu Shang from Brawlhalla.

On April 1, 2021, it was announced that four popular fan-made characters from the Steam Workshop would be officially added to the game in late 2021 via a free update: Mollo, Hodan, Pomme, and Olympia.

[9] The realm of Aether is inhabited by many races of anthropomorphic animals divided primarily between four warring civilisations, each of which holds power over a different element: fire, water, earth or air.

At Loxodont's coronation, the ceremonial flame is stolen by a figure resembling Orcane, and he is pursued by Zetterburn, who attacks Merchant Port in a rage.

Zetterburn begins tracking the shadow back to its place of origin, while the real Orcane, returning from his mission, decides to follow.

In the Aetherian Forest, guardian Maypul senses a strange sickness is causing the plant life to rot and leaves her sister Mayreed behind to search for its source.

When Maypul accuses him, Forsburn reveals he had an encounter with a shadow resembling his brother, and speculates this to be the source of the sickness affecting the forest.

While on a scouting mission for the Air Armada, wingmen Wrastor and Bradshaw spot a giant breach in the Rock Wall surrounding the Aetherian Forest and descend to investigate.

[12] In 2019, the official Rivals of Aether Twitter account confirmed that the Steam workshop would be available for players to create their own characters and stages.

On April 1, 2021, it was revealed that four of the original characters released via the Steam Workshop would be officially added in a forthcoming free update.

Nick Valdez of Destructoid scored the game 90/100, saying it is a fully fleshed out fighter that adds additional depth to the Super Smash Bros.

[4] Di Stefano Castelli of IGN Italia rated the game 81/100, saying that it lacks originality, but is a technically proficient remake appealing to hardcore players.

[16] Another spin-off, the deck-building game Creatures of Aether, was originally released on September 28, 2020, and later received a PC version on August 2, 2021.
