Produced under the supervision of Sonic Team, this two-part Japanese anime brought to life another version of Sonic the Hedgehog, also based on the games but once again being significantly different. Given no clear backstory, it is established that Sonic lives somewhere on South Island in the ruins of an airliner, and prefers to relax in this tropical locale then being needlessly bothered by other people. Sonic's personality leans more toward his Fleetway counterpart than his Adventures of Sonic the Hedgehog one. While he will still rush in to save his friends from certain danger and Dr. Eggman, there are times when he wishes to be left alone, and can suddenly snap at even his closest friends and allies.
Once again under the supervision of Sonic Team, Sonic X is closely based on the Sonic Adventure-era Sonic, even sharing the same voice actors in the Japanese original. The one major difference is that Sonic and friends are from another, unnamed planet and are transported to Earth through a machine emitting Chaos Control. Once there, they make friends with Chris Thorndyke and his family, who oftentimes is portrayed as Sonic's other sidekick, but constantly in need of Sonic's help. While the first half of series one is an original story, the second half decided to adapt Sonic Adventure, Sonic Adventure 2 and Sonic Battle, making changes as necessary to stay in line with the continuity they created with the first 26 episodes. While this has been the closest the video game version of Sonic the Hedgehog has come to an animated form, there are still significant differences which make Sonic X its own unique world.
