Thrash the Tasmanian Devil, a character introduced in Archie's Sonic the Hedgehog comics, is based on a purple sprite that is created for several milliseconds on the game's title screen if the player quickly switches between Sonic and Knuckles' sprites. Notably, Ian Flynn stated in the graphic novel "Sonic Universe 3: Knuckles Returns" that Thrash was meant to be another rogue of Knuckles who could "throw down with Knuckles and have it mean something", which did not line up with his role in his debut during "Sonic Universe" Issue #11. However, this would later be conveyed during the "Endangered Species" story arc of the main comic, where it's revealed that he has a strong hatred towards the Echidna species due to their actions against his ancestors. When asked about the possibility of bringing Thrash back in the comic's reboot, Ian Flynn said he would love to bring him back, but "it comes with all that baggage... We can't really bring him back without people going 'Oh boy! And here we go!'"
