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 Nintendo Switch, Xbox One, PlayStation 4, Xbox Series X/S, and PlayStation 5. 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
Like Sonic Adventure, Chao in Space is a 3D platform game with action and role-playing elements, and also flight simulator themes. Players control the Chao Cookie as they venture to defeat the Dark Emerald Empire and save the galaxy. At the start of the game, the player is placed in one of several Adventure Fields, open-ended hub worlds inhabited by advice-giving non-player characters. The player character is guided and instructed by Omochao. Through exploration, the player discovers entrances to levels called Action Stages, some of which must be opened using keys hidden in the Adventure Field. Once the player accesses an Action Stage, they are tasked with a specific objective. There are two types of Action Stages: the Standard Stages, on which Cookie must defend himself with combat moves, and specific equipment. Others are Flight Stages, on which Cookie pilots his starship, the Winged Wisp.

Behind the fictional film's scenes, the character is portrayed by Knuckles the Echidna. Solon is heavily influenced in the Power Rangers character Zordon.
 * 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.

Appearing outside the story's universe, Tails is one of the producers of Chao in Space.
 * Knuckles the Echidna (voiced by Dave B. 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. Initially put to work as a janitor, Cookie (encouraged by a vision of Tikal) soon proves himself when he manages to defeat a small invading pack of Dark Emerald robots, and their leader the Commander. Seeing Cookie's potential, the Alliance's leader General Solon has him train to become one of the Alliance's new agents.
