With the exception of Knuckles, the Chaotix, and a few others,
Knuckles the Echidna featured a completely original cast of characters created specifically for the book, some of whom went on to play a large part in Archie's main
Sonic the Hedgehog series and universe.
Heroes •
Knuckles the Echidna Sworn guardian of the Floating Island trained by his father Locke. While often headstong and gullible, Knuckles has a strong sense of justice and is always willing to protect the innocent. •
Julie-Su A former soldier of the villainous Dark Legion, Julie-Su is a female echidna who has since defected and become one of Knuckles' closest allies. Often depicted as Knuckles' love interest, Julie-Su has a psychic connection to Knuckles through a phenomenon known as the Soultouch, which has designated her and Knuckles to be
soulmates. •
Chaotix A group of warriors formed by Knuckles to help him defend the Floating Island, the Chaotix consists of the laid-back
crocodile Vector, the spunky
armadillo Mighty, the mischievous
bee Charmy and the mysterious
chameleon Espio. Later in the series, Julie-Su joins their ranks. •
Locke the Echidna Knuckles' father and a loyal member of the Brotherhood of Guardians, Locke trained his son to guard the Floating Island, but seemingly abandoned him at a young age. Locke makes short, sporadic reappearances throughout the series to guide his son. •
Archimedes A fire ant who mentors Knuckles. While kind and good natured, his mysterious nature often frustrates Knuckles. •
The Brotherhood of Guardians An order of echidnas formed by Knuckles' ancestor Edmund who have dedicated their lives to protecting the Floating Island. The Brotherhood operates from a secret headquarters to assist and guide their descendants, namely Knuckles.
Villains •
Dimitri the Echidna (Enerjak) Knuckles' great-great-granduncle and supreme leader of the Dark Legion, Dimitri arguably serves as the series' main antagonist. Having once stolen the power of eleven Chaos Emeralds that were sustaining the Floating Island, he was transformed into Enerjak, a godlike being seeking to reform echidna society in his own image. Albeit eventually drained of his powers, Dimitri was rebuilt as a cyborg and continued to lead the Dark Legion. •
Renfield T. Rodent A former ally of Sonic's arch-nemesis
Doctor Robotnik, Renfield is a shady businessman with underworld connections who operates the Happyland theme park on the Floating Island. •
General Helmut von Stryker The leader of the dingoes, General Stryker is a huge, muscled soldier with an aggressive nature and a hatred of echidnas. •
The Dark Legion The antithesis to the Brotherhood of Guardians, the Legion is an army of cyborg echidnas who worship technology. Its leaders (known as Grandmasters) are descendants of Dimitri the Echidna. ==Reception==
