Does Sonic need recurring villains? I noticed people talking about this with the DC Crossover. Comic heroes like the Justice League have them because it's the nature of longform media. Their stories have been told over countless comic strips, books, and franchise reboots for nearly a century. Unlike Sonic stories which are generally made for standalone release. I can't think of many video game characters at all who have lasting iconic rogues gallery like Spidey or Batman do. It's usually that ONE bad guy from the earliest iterations that everybody knows. Bowser, Ganon, Ridley, Team Rocket, Sephiroth, Dr. Wily, or our very own Dr. Eggman.
