Sonic Presents... Chao in Space

Sonic Presents: Chao in Space (or simply Chao in Space) is a platform video game developed by Sonic Team and published by Sega for the Xbox One and PlayStation 4. A spin-off to the Sonic the Hedgehog series, it is inspired on the posters originally found in the Sonic Adventure series, which announced the fictional film of the same name.

Premise
Set in the fictional titular motion picture Chao in Space (co-produced and directed by Sonic the Hedgehog), the game follows Cookie, a brave-hearted Chao who travels in space alongside his brothers Digger and Crayola, and the Galactic Chao Alliance to stop the Dark Emerald Empire from conquering their galaxy. Sonic himself and his friends also appear, albeit outside the fictional film's universe, and watching its events in the film's theatrical release.

Gameplay

 * Omochao (voiced by Erica Lindbeck) - A mass-produced, robotic Chao with virtually unlimited knowledge about the world. Appearing in the game's fictional film, Omochao portrays himself as a high-ranking member of the Alliance. As in the previous Sonic the Hedgehog games, Omochao serves as an informant to the characters and a universal Hint to the players.

Mitchell) - Sonic's other best friend and adventure partner, he is a red anthropomorphic echidna from Angel Island with the ability to glide and climb up walls, and is a powerful fighter with superhuman strength due to his spiked fists.

Plot
Having finished the shooting of their movie Chao in Space after six months, Sonic the Hedgehog (the film's director and producer) and his friends (including co-producers Miles "Tails" Prower and Knuckles the Echidna) find themselves ready for the movie's theatrical release, which takes place in the Westopolis World Premiere theater. The game's story continues with the movie's story.

A few millennia ago, the Chaos and Master Emeralds were kept at an altar near the territory of a clan of echidnas (the Knuckles Clan). Tikal, daughter of Chief Pachacamac, befriended the Chao who lived at the altar and their protector, the water god Chaos. When Pachacamac sought to expand his clan's territory, he wanted to steal the Chaos Emeralds and use their power to defeat his rivals. Although Tikal and the Chao stood against him, he ordered his soldiers to charge anyway, resulting in many Chao being injured. This enraged Chaos, who transformed into a terrifying, giant monster and destroyed all of the echidnas, except for Tikal. Tikal sealed herself away in the Master Emerald with Chaos, and the magic caused the area surrounding the shrine to become Angel Island. The Chao Emeralds were also sealed away while part of their energies were transferred into seven Chaos Drives (also known as Star Drives) which were soon lost in space.

In the present day, Cookie, a Chao who dreams to become an astronaut, is taken in by his brothers Digger and Crayola to join the Galactic Chao Alliance, a partisan resistance movement and private paramilitary force dedicated in protecting the galaxy from several threats. On this period, the Alliance is at war with the Dark Emerald Empire led by Void the Dark Chao, who seeks to conquer the Chao planet by releasing and taming Chaos.
