James Cameron's Sonic
A group of scientists and astronauts discover and explore Mobius, an alternate futurist version of Earth where animals have evolved to human level. While travelling in the new planet, a reporter and her astronaut fiancee meet and form a friendship with Sonic the Hedgehog, who is determined to protect his world and Earth from potential threats such as his nemesis Dr. Eggman and mercenaries and smugglers from Earth hired to collect the Chaos Emeralds and capture animals on Earth and Mobius to robotize them as slaves for Eggman's corrupt empire. Sonic and his comrades must also work together to save the world from a powerful enemy who seeks to wipe out all life on both Earth and Mobius.

Sonic Returns
The film centers around Sonic and his friends travelling alongside Vicky Lane and Travis Lawton into the Sol Dimension, an alternate reality where Earth and Mobius are one same planet. There, they fight alongside their new allies Silver the Hedgehog and Blaze the Cat against a new enemy known as Infinite, who threatens their both dimensions. While they follow Sonic and his friends, Vicky and Travis also end up reuniting with Vicky's missing sister Angie and Travis' father Robert, who were both presumed to have been killed in a space accident two years ago, but turn out to be stranded in the Sol Dimension.

Fang the Sniper
Set in a Old West-themed town of Mobius, Nack the Weasel ends up changing his name to "Fang the Sniper" as the town's new sheriff in a attempt to escape a bounty placed on his head by the town's ambitious mayor, who secretly happens to be another infamous outlaw.

(Guardian Units of Nations) forces in the battle against the invasion of the Black Arms led by Black Doom, who is manipulating dangerous thieves and bandits of Mobius to help conquer the planet.

Sonic and his friends work alongside Sally and the Freedom Fighters to stop Eggman and his robotic forces from conquering the secrets about G.U.N. Forces which include files about his grandfather Professor Gerald's secret project, which can bring doom to the world if in wrong hands. Things will get more complicated when Scourge the Hedgehog, Sonic's evil counterpart from other realities, also gets involved in the chaos and seeks Gerald's project for his own purposes.

Fang: No Man’s Land
Fang is reunited with his old ally Bean the Dynamite as they fight off a relentless group of mercenaries who are out to collect a bounty on both of their heads by a couple of dastardly outlaws.

The film reveals the origin of the friendship between Silver and Blaze and the battles and adventures they had in the Sol Dimension, including their first encounter with Lane Stargate astronaults Angelica "Angie" Lane and Robert Lawton.

Chaotix: Between Dark and Light
When an ancient arcane being known as Walter Naugus plans to unleash a world-Eating entity known as Dark Gaia, the Chaotix head on a quest to solve secrets about the Gaia Manuscripts with the help of a immortal being known as Light Gaia to stop Naugus and his schemes.

Sonic Across the Universe
Following the events of Sonic World Run, Sonic, followed by his uncle Chuck, travels across alternate realities of Time and Space to solve secrets of his past and reunite with his long lost cousin Sapphire and siblings Sonia and Manic. His adventure will soon lead him to an encounter with superhuman hedgehogs from other dimensions, with some joining his journey.
