Trivia

 * This series is set in the Sonic: Rebirth continuity.
 * When asked about adding characters from other continuities (such as comic books and television), Ian replied that he's likely to add some fan-favorites such as Sally Acorn, Nicole the Holo-Lynx, Sticks the Badger, Tangle the Lemur, Whisper the Wolf and Jewel the Beetle in a near future (especially since they already appear on Sonic: Across Mobius), although his priority is focusing on the game characters for now, even that he showed interest on adding them by late Season 2.
 * The only exception for now is Agent Topaz, since she originated from Sonic X.
 * Considering the series' timeline depends of the video game series' one, characters like the Babylon Rogues and Infinite would only show up after their game debut.
