  • This series is mainly set in the Rebirth continuity, although new concepts will be introduced as well.
    • As a result, characters like Silver and Blaze don't appear until their games are released.
  • Despite not featuring characters from Sonic SatAM and its Archie Comics spin-off, the comic adopts some concepts introduced by them, including the use of the name Mobius for the comic's setting, Sonic's crew being named Freedom Fighters, Bean and Bark being part of Fang's gang and Honey's backstory as a fashion designer.
    • However, both Sally and Nicole, both originating from SatAM and both prominent characters in the Archie Comics continuity, are the only exceptions for now and, much like the Post-SGW comics, Sonic and Sally are just friends, although it didn't stop fans from shipping them once more alongside Tails with Nicole.
    • While not planning to add other SatAM/Archie characters for now, the writers expressed interest on reintroducing Antoine D'Coolette and Bunnie Rabbot into it.
  • The comic also includes characters introduced in the IDW Publishing continuity as well.
  • During the comic's run, there's hints for several possible pairings, aside from the ones mentioned above, including Sonic/Amy, Sonic/Tiara, Tails/Cream, Tails/Marine, Tails/Honey, Knuckles/Tikal, Knuckles/Shade, Shadow/Rouge and Silver/Blaze, with Sonic/Ophelia, Tails/Anna, Knuckles/Rouge, Knuckles/Jasmine, Amy/Buckeye and Sally/Obsidian being mainly played for laughs.
    • Depending of the point of view of the reader, some moments can be interpreted as yaoi subtext, mainly between Sonic and Tails, Sonic and Knuckles, Sonic and Shadow, Sonic and Jet, Knuckles and Vector, Shadow and Silver and Orbot and Cubot, and some as yuri subtext, mainly between Amy and Sally, Amy and Tiara, Amy and Rouge, Amy and Blaze, Amy and Honey, Sally and Tiara, Cream and Nicole, Cream and Marine and Rouge and Topaz.
  • Wendy is notably younger, being aged down to her twenties.
  • Jasmine is based on both Jasmine from Aladdin and Shantae from her titular game series.
  • It is theorized that the Sonic universe is part of a larger multiverse that connects to most of Sega's own video games universes.
