Plot synopsis

Series 1 (Seasons 1-2)

During a mission to rescue Cream the Rabbit and Cheese the Chao from Dr. Eggman's headquarters, Sonic and his friends are caught in an explosion that transports them to what seems to be another dimension. Sonic's life is eventually saved from drowning by a twelve year old boy named Christopher Thorndyke. Chris lives in a mansion owned by his two celebrity parents with his inventor grandfather. Chris aids Sonic in locating his friends, and it is not long before Dr. Eggman reappears. Sonic and Eggman race to collect all the Chaos Emeralds in the first 26 episodes and eventually, all of the Chaos Emeralds are retrieved and Chaos Control warped parts of their home to Earth (like Angel Island). The rest of the season features plots based on the Sonic games. In the end, Chris' grandfather invents a portal to send Sonic and everything else from his world. Before he leaves, Chris kidnaps him because he does not want Sonic to abandon him like his parents did. Eventually, Chris comes to terms with his feelings and Sonic returns to his own dimension.

Series 2 (Season 3)

It has been years since Sonic and friends returned to their dimension. Chris is now eighteen and has been working on repairing his grandfather's dimensional portal. A plant being named Cosmo arrives on Sonic's planet, looking for the one who can wield the powers of the Chaos Emeralds. Sonic, having been nearly defeated by a new enemy called Dark Oak, scatters the Chaos Emeralds across the galaxy to prevent Dark Oak from using their power. When Chris uses the portal, he suddenly finds himself in Sonic's world. His age has reversed back to the age when he met Sonic. However, Chris still has all his memories of the years since. To Sonic, only six months had passed. During their reunion, Dark Oak and his Metarex army (similar to the Black Arms from the Sonic games) attack steal the "Planet Egg" from Sonic's planet. Without the Egg, all the plants on the planet wither. Once again, Sonic and friends venture into space to retrieve the Chaos Emeralds. After many run-ins with Dr. Eggman and the pursuing Metarex, Cosmo is eventually unveiled as an unwilling spy for the Metarex, who are part of the same race of anthropomorphic plants that Cosmo from. When the Metarex enact a plan that could destroy the universe, Cosmo sacrifices herself with the help of Super Sonic and Super Shadow, and her essence is manifested in the form of a seed. With Metarex destroyed, Eggman helps Chris to be sent back home. Soon thereafter, Dr. Eggman revives his previous rivalry with Sonic, albeit a light-hearted one.

List of characters



Exclusive characters

American version

In 2003, 4Kids Entertainment and VIZ Media co-licensed Sonic X for the United States, with the series being distributed by FUNimation. The episodes were then localized for the intended demographic, including the complete replacement of the score, as well as removing suggestive content and changing the fate of several characters. For example, Maria Robotnik is originally killed aboard the Space Colony ARK, while in the edited version, she is merely captured. Her death remains intact in the video games where the series was adapted from. Other continuity errors include mislabelling "Chaos Control" as Doctor Eggman's base. While both English and Japanese characters were digitally removed or replaced with incoherent symbols, Chinese characters were unedited in The Adventures of Knuckles and Hawk, in coherence with the episode's setting.

4Kids did not cast the voice actors from the Sonic games and went with their in-house VAs. Mike Pollock, the current voice actor for Doctor Eggman, stated during an interview that he was provided samples of the game's voiceovers as a reference. However, when a producer for the series was asked about any prior experience with the Sonic franchise, he replied, "I've never played the game, seen the series or read the comics." After the passing of Deem Bristow, the voice actor for Eggman in the previous games, the 4Kids VAs were recast for Shadow the Hedgehog and subsequent Sonic games.

Theme songs

For the United Kingdom, Australia, Latin America, much of Europe, and Brazil, the opening song was performed by a female singer repeating the show's title numerous times, the U.S. ending theme was kept, however, and all of the inserts were edited out of the English version.
