Over its history, the series has seen a number of spin-off publications being created – these include Sonic Universe, which focuses on stories revolving around different side characters from the main series Knuckles the Echidna, focusing on adventures involving Knuckles and his friends the Chaotix Sonic X, a comic series based on the 2003 Japanese anime of the same name and Sonic Boom, a comic series based on both the cartoon series and the video game series of the same name. Following a lawsuit in 2013 by former writer Ken Penders, Archie rebooted the series, removing several characters from the comics' continuity and moving it closer to that of the games. While the series largely consists of its own continuity, certain issues implemented aspects of the Sonic video games into their plots and settings. The series features a cast of hundreds of characters, consisting of those derived from the Sonic games and those original to the comics, with stories focused on a crime-fighting organization called the Freedom Fighters, led by Sonic, as they face off against series antagonist Doctor Eggman alongside a variety of other villains. The series ran for 290 issues for over 20 years, earning a place in the 2008 Guinness World Records for being the 'longest-running comic series based on a video game', and it became the longest-running franchise-based comic series in 2015, surpassing Marvel Comics' Conan the Barbarian (which ran for 275 issues) before it was confirmed cancelled in July 2017 (although the comics ceased release in January of that year), following Sega and Archie Comics' decision to discontinue their business relationship. After initially beginning with a four issue miniseries between 19, the first full-length issue of the comic was published in July 1993. The series was based on Sega's video game franchise as well as DiC Entertainment's 1993 animated series of the same name.

Sonic the Hedgehog was an American comic book series published by Archie Comics, in partnership with Sega.
