Sonic X is the newest Sonic the Hedgehog television series, based roughly on the storylines of the Sonic Adventure series. It was animated and produced in Japan by TMS Entertainment with the partnership of Sega and Sonic Team. 52 episodes were aired.

In 2003, 4Kids Entertainment licensed Sonic X for American television broadcasting, and it is currently airing on 4Kids TV (formerly the Fox Box). The U.S. licensing is a joint effort between 4Kids and ShoPro Entertainment. Despite the series doing less than stellar in Japan, the series gained popularity abroad. This prompted Sega to buy shares in TMS Entertainment, which was in danger of bankruptcy at the time. Soon, a second series of 26 additional episodes were produced and originally aired in France. Although these episodes were never shown in Japan, it is interesting to note that a full Japanese language track had been recorded for these episodes, as shown by the VCDs released in China.

Story and Premise

The first 26 episodes of Sonic X dealt primarily with Sonic and most of the main cast suddenly transporting on Earth during a Chaos Control incident at Eggman's base. On Earth, Sonic finds hospitality in a human boy named Chris, who provides Sonic and friends with shelter and support against Dr. Eggman's ambitions to conquer the current world. The next 12 episodes dealt primarily with the storylines of the Sonic Adventure series and roughly adapted them, most notably introducing Shadow (who does not appear again until the second series, which compose of episodes 53 to 78). As the series was drawing to a conclusion at the time, characters such as Vanilla, the Chaotix, and Sonic's animal buddies showed up briefly in cameo appearances, though the Chaotix became somewhat recurring characters in the second series.

As Sonic and friends finally travel back to their homeworld by the end of episode 52, for the second series they travel into space in order to defeat an army known as the Metarex, bent on conquering the universe. Along with the main Sonic cast, Chris finally invents a device to take him to Sonic's world (as he designs it when he is an adult scientist, it has a side-effect of rendering him back as a child all over again) and a new plant-like girl by the name of Cosmo assists them in their journey.

Production

Sonic X first entered production as early as 2001 when TMS Entertainment, Sega, and Sonic Team produced their first pilot for the series, which ran close to 4 minutes in length. The pilot did not have a name at the time and was simply called "Sonic". The overall presentation of the pilot was also vastly different than how the series would be produced. In the pilot, the series seems to take place in a fictional world, similar to that of Adventures of Sonic the Hedgehog and SatAM (which interestingly enough, TMS Entertainment provided animation services to both), and had a futuristic look to it. Other than Dr. Eggman, there were no other Humans present in the pilot.

Several noticable things about the pilot were that there were Crystals in similar appearance to the Master Emerald's Shards, rather than Chaos Emeralds and the fact that Cheese the Chao did not have a finalized name. Instead, the pilot simply calls him Chao. Another unusual thing is the pilot has an English narration, as opposed to a Japanese one. It is possible that time, the production team were looking at foreign markets to produce the animation, before making the decision to produce it for the Japanese Market.

However, despite the fact the pilot was never publically shown or announced, rumours began to circulate early 2002 of a new Sonic animation project in the works. It wasn't until later that Sonic X got an officially confirmination by a promotional flyer and a press release by the Japanese companies. The same year, TMS Entertainment produced another pilot for the series, which was much more closer in nature to the final version of the series. However, this pilot was shorter than the previous one and was also recorded in Japanese. Cheese was also officially named in this pilot as well. The pilot was later unvealed at World Hobby Fair and Tokyo Gaming Show.

On April 6, 2003, TV Tokyo began broadcasting Sonic X on it's Sunday morning timeslot, at 8:30AM. Not long after, Sonic X was announced to be licensed by 4Kids Entertainment in the United States, who secured rights to the series outside of Asia. However, Jetix of France secured the rights to their region before 4Kids licensing. As a result, France based their version on the Japanese version, rather than 4Kids version. In July, TF1 began broadcasting the series in France and on August 2003, 4Kids began officially broadcasting the series in the United States on FoxBox (now known as 4Kids.tv).

During it's run on TV Tokyo, it ran for 52 episodes before getting replaced by Bijutsu wa Tanoshi. However, despite recieving a full 52 episode run, the series ratings were under expectations. However, there is a chance this may have been influenced due to being put up against TV Asahi's Magical Girl timeslot, which ran Ashita no Nadja, then Furati wa Pretty Cure during it's airing. Despite it's subpar ratings in Japan, the series gained more success in territories outside of Japan, especially throughout Europe.

On June 2004, it was officially announced that additional episodes would be produced, though it was generally though at the time that 4Kids Entertainment secured additional episode from TMS Entertainment. It wasn't until several monthes later, production scripts, storyboards, layout designs, and character designs for these episodes began to show up on Yahoo! Auctions Japan. At first, it was generally though to be a hoax, since neither TMS Entertainment nor Sega had officially announced these episodes. It wasn't until France confirmed additional episodes would begin broadcast in March 2005 that people began to believe this information. Thailand began to broadcast the new episodes in February 2005, but it wasn't noticed until several episodes in that the broadcast station was airing them and was the first physical evidence of the new episodes.

Characters

Along with many characters from the video game series (especially those from the Sonic Adventure series), Sonic X introduces additional cast members exclusive to the anime.

Season 1

• Bokkun - A hyperactive, childish robot who acts as Eggman's messenger. He loves setting off explosives in messages that he sends to Sonic and friends, and occasionally to Eggman as well.
• Chris Thorndyke - A well-off boy who helps out Sonic from the very beginning. Due to past loneliness and emotional distance from his family, Chris becomes strongly attached to Sonic.
• Chuck Thorndyke - Chris' grandfather, a mechanic and inventor of sorts. He and Tails often work together on a number of machines, including the X-Tornado, an upgrade to the Tornado 2.
• Danny, Frances, and Helen - Chris' friends who occasionally lingered with the Sonic cast during the early episodes.
• Decoe and Bocoe - Two comical robots that are constantly by Dr. Eggman's side, working at his every command while making side comments about their job. They play minor roles in virtually every episode they appear in except for episode 48.
• E-Series - Other than the ones established in the games, most E-series robots are Sonic X-exclusive and, for the most part of series 1, act as the generic monsters-of-the-week. See below for a list of them.
• Ella and Tanaka - The Thorndykes' maid and butler respectively.
• Jerome Wise - A man who used to work under the President. At first Jerome tries to prevent the President's reputation from being ruined by Sonic. He gets fired when it was found out that he made a deal with Dr. Eggman, and he ends up homeless on the streets.
• Nelson Thorndyke and Lindsay Fay - Chris' parents who are often away working, resulting in a great deal of emotional distance between themselves and their son.
• Sam Speed - Leader of the S-Team and Chris' uncle. Sam attempts to capture Sonic on the highways, but he is effortlessly outraced. Since then, he has always deemed himself as Sonic's rival. He bestows upon himself many nicknames in the Japanese version.
• Topaz - A female GUN agent who often worked alongside Rouge on missions issued by the President.

Season 2

• Cosmo - A girl from another planet that first shows up in episode 53. She journeys to Sonic's planet in hopes of finding him, since it is believed that his usage of the Chaos Emeralds can help save the galaxy from the Metarex.
• Dark Oak - The leader of the Metarex in episodes 53-78 and the primary villain of series 2. As Sonic was unable to defeat him originally even in his super state, he transports the emeralds to distant corners of the galaxy, preventing Dark Oak from obtaining them.

E-Series Robots

Note: Some of the E-Series have no codenames stated in the Japanese version of Sonic X. The names given to E-11, E-14, E-23, E-43, E-47, and E-90 in the American dub by 4Kids are the closest one can get for a name until the official source for the Japanese codenames reveals the original names.

• E-11 Beacon: (episodes 4 and 12) Dr. Eggman summons this robot to accompany him to where a Chaos Emerald has been found. Although it held Sonic at bay by bouncing him around in the air, it was quickly defeated when Sonic obtained a ring. It is later again seen during the attack on Eggman's base.
• E-12: (episode 28) It attacks Sonic and Tails while Tails was having a dream.
• E-13: (episodes 1, 11, 12, and 13). Minor guard robots which have no plot centered around them. All they apparently do is attack intruders.
• E-14 Sneezer: (episodes 1, 11, 12, and 13). Much like the E-13 above, their only function is to pursue intruders.
• E-18 Guerra-Hard: (episode 13) Sonic confronts this powerful, gigantic robot inside Dr. Eggman's base.
• E-21 Ballios: (episode 10) These baseball-playing robots make up Dr. Eggman's "Eggs Team" when a Chaos Emerald is discovered at the Diamond Stadium.
• E-23 Missile Wrist: (episodes 3, 11, and 39 (flashback, dub only)) This is Eggman's first robot used to terrorize Station Square when he announces to take over the human world. It later appears when GUN sneaks into Eggman's base as an empty, nonfunctional shell, and it is brought back to the government base for an analysis.
• E-35 Funfun: (episodes 12 and 13) While Dr. Eggman was away from his base tracking down the most recently discovered Chaos Emerald, he brought along this robot. Funfun has a powerful fan installed in him that is capable of blowing his opponents away, which Tails was barely able to hold off in his X-Cyclone, although Sonic managed to defeat it easily.
• E-38 Octoron: (episode 9) This robot causes havok at Emerald Coast.
• E-39 Quizon: (episode 9) These robots construct a theme park called "Eggman's Sea Park" ("Eggman's Scream Park" in the English version) in place of Hotel de Blanc at Emerald Coast. After Sonic destroys Octoron, they combine themselves into one gigantic robot (referred to as "Serpenter" in the dub). Although Sonic step up to fight it off, Amy was the one to defeat it using her trademark hammer.
• E-42 Torole: (episode 15) These robots show up to wreak everything in sight once Dr. Eggman's recently launched Egg Fort arrives at the mall.
• E-43 Falcon: (episode 15) These robots appear and attack Sonic when he shows up to stop the Egg Fort for the first time.
• E-45 Sumo-Man: (episode 21) He basically acts as a road block during a race between Sonic and Sam Speed. They both manage to get pass him, however, apparently without much notice towards him.
• E-47 Pumpty: (episode 5) This robot has a clear-glass container used to capture Sonic's friends while Sonic is out fighting Knuckles. Although Amy severely damages its main generator, Knuckles ultimately is the one to defeat it.
• E-51 Intelligente (pronounced In-tella-hen-tay): (episode 6) A schoolteacher robot that takes over Chris's class as as the new teacher, to which the children respond positively. He refuses to follow Dr. Eggman's orders until Eggman shows up in person, threatening to dismantle him. Sonic defeats him after E-51 selfishly goes back to being a mindless servant.
• E-57 Clurken: (episode 16) Attacks Sonic and friends when a Chaos Emerald has been found under the ocean.
• E-65 Gorru-Gaooh: (episode 18) Attacks Sonic while he is in Africa with Chris and Tails.
• E-66 Da-Dai-Oh: (episode 22) Attacks Sonic's friends at a Chao colony, tracking mud into the river in the process.
• E-70 Noizi: (episode 11) Guards the Chaos Emerald Dr. Eggman stole at Diamond Stadium. It is capable of making loud deafening noises.
• E-74 Weazo: (episode 23) Attacks Sonic and friends in a movie studio where yet another Chaos Emerald has been found.
• E-77 Lucky: (episodes 25, 26, 45, and 46) Dr. Eggman sends out this petite, bell-shaped robot to look for the final Chaos Emerald. He is made out of lucky charms, but this appears to be merely dumb luck. Lucky has an apparent desire to be praised, as he willingly offers Sonic the Chaos Emerald upon complimenting him. Although his immediate fate was unknown at the time, Lucky is last seen fighting in a martial arts tournament held by the President.
• E-88 Lightning Bird: (episode 24) A huge robot that acts very much like a chicken, it attacks Sonic at a farm. A piece of loose machinery falls into Sonic's ear, eventually causing him to run uncontrollably for nearly the entire episode.
• E-90 Super Sweeper: (episode 8) This robot sucks up all the satellites in space so Dr. Eggman can launch his television channel.
• E-91 Ku-no-i-chi: (episode 17) The only female E-Series robot, and is modeled after a ninja. Quoted from Dr. Eggman in the Japanese version: "Sometimes she's a driver, sometimes she's a female guard, and sometimes she's a sexy dancer... but her true identity is E-91, Ku-no-i-chi!" E-91's codename roughly translates to "Lady Ninja".
• E-99 Egg Emperor: (episode 26) A highly massive E-Series robot that is a reformation of the Egg Fort 2. Using the power of the Chaos Emeralds, he is able to move faster than Sonic himself, appearing to him as a mere blur. Although Eggman enjoyed playing around with Sonic at first, E-99 eventually went out of his control and started pummeling Sonic with full force. Because of this, Sonic was completely unable to fight him and was rendered severely injured. After E-99 seemingly kills Sonic by throwing him into the ocean, Chris (who was being held ransom by Eggman) breaks out of his restraints and accidentally drops the Chaos Emeralds into the ocean. Ultimately, E-99 is destroyed by Super Sonic, although it has proved to be one of the most fierce of Eggman's creations in the series. (Note: In the English version, E-99's codename is "Eggsterminator". Its Japanese name is shared with that of the normal final boss in Sonic Heroes, although it is unknown if this was the reason for 4Kids altering it.)

4Kids English Version

Common with all of their licenses, 4Kids edited the show to keep up with broadcasting guidelines. This version of Sonic X has been criticized by some for editing out whole portions, changing the soundtrack, and re-wording certain phrases to make it more kid friendly, which is why many Sonic X fans prefer the original Japanese version. However, in comparison with some other 4Kids titles, the English version of Sonic X had remained relatively faithful to the original in terms of overall script and episode count.

It was written by Russel Velazquez, Joseph Garrity, and Norman Grossfield, and it appeared on the compilation soundtrack True Blue (strangely in place of "SONIC DRIVE").

In 2004, an original soundtrack was released by Wave Master, featuring select BGM, four versions of "SONIC DRIVE" (including the full version), and "Mi-Ra-I."

Gameboy Advance Video

Two Game Boy Advance Videos (GBA Video Volume 1 and GBA Video Volume 2) with the first four episodes of Sonic X were produced.
