Sonic X is the Japanese anime and the most well-known StH show. The Adventures of Sonic the Hedgehog was the first StH ipakita which was made for the younger fans of Sonic. Sonic the Hedgehog (commonly known as SatAM) was made around the same time as AoStH to appeal to the older fans of Sonic and introduced the characters now seen and used in the Archie Sonic comics. Sonic Underground was another ipakita made after SatAM was cancelled (and the rights to SatAM were madami or less ibingiay to Archie Comics), this ipakita introduced Sonic's siblings Manic and Sonia. There was also an OVA made in Hapon for StH, though it was released in the U.S as a film.
