Trivia

 * The series mainly follows the game canon, although with a few liberties like changing the order of the events and introducing both elements from some spin-offs and original concepts.
 * The series officializes Mobius as the name of its setting.
 * The series reintroduces Mighty, Ray and Honey years after being forgotten.
 * Topaz and Sam Speed, then exclusives to Sonic X, are reintroduced in this series.
 * The events of Sonic Generations are ignored due to writers believing it's redundant to have a time-travel plot as they confirmed Classic Sonic exists instead as TBD.
 * In part due to legally not being able to use concepts introduced in Sonic Chronicles due to a lawsuit by Ken Penders, the writers created an original villainous Echidna group in order to circumvent the legal problems.

Easter eggs

 * While her primary clothes are still red, Amy has occasionally used blue clothing and has occasionally been nicknamed Princess, even if derrogatorily.
 * Cream talks with a slight Southern accent.
 * The character of Sadie Speed is modeled after NASCAR racer Danica Patrick as a nod to being playable on Sonic & All-Stars Racing Transformed.
