  • Eggman's henchbots Decoe and Bocoe are replaced by Orbot and Cubot to keep uniformity within the games and to symbolize a little timeskip as well as it's revealed that they were deactivated to build them.
  • Since 4Kids Entertainment, who dubbed and distributed the original series, went defunct, the English dub of this series features the post-2010 voice cast instead to keep coherence within the games.
    • Despite that, some 4Kids voice actors who now do voice work in Los Angeles reprise their roles.
    • This series is also subject to less edits in the English dub.
  • Note to readers: Cristina Vee isn't the canon new voice for Amy. She's a placeholder for at least this page until an official replacement comes.
