* Limited Role: The Babylon Rogues were created specifically for the Sonic Riders series. They serve as the main antagonists in Sonic Riders, Sonic Riders: Zero Gravity, and Sonic Free Riders.
* Unique Gameplay: Their unique flying vehicles and the focus on extreme sports gameplay are tied directly to the Riders series. It would be difficult to incorporate them into traditional Sonic games without significantly changing their role.
* Limited Popularity: While they have a dedicated fan base, the Babylon Rogues aren't among the most popular Sonic characters. This makes it less likely for Sega to prioritize their inclusion in other games.
However, it's not impossible:
* Cameo Appearances: The Babylon Rogues might make cameo appearances in future Sonic games, similar to how other characters have been included in non-primary roles (like Shadow in Sonic Frontiers).
* Spin-Offs: There's always a chance for a spin-off game specifically focused on the Babylon Rogues, perhaps exploring their origins or continuing their story.
Ultimately, it's up to Sega to decide if and how they want to utilize the Babylon Rogues in future games. While they haven't appeared outside the Riders series so far, their unique personalities and potential for story development keep them a possibility for future appearances.
