I’m calling it. The sequel will be about Sonic and Tails (with the unintentional stowaways Donut Lord and Pretzel Lady) traveling back to Mobius to save a kidnapped Princess Amy from the echidna tribe, which is working with Eggman and his new creation Metal Sonic (powered by the quill) to collect all 7 Chaos Emeralds to power the army of badnicks he has built. Will reveal that Sonic’s unique power allows him to directly channel the power of the emeralds. Which will inspire Eggman to create Shadow using the brain and or DNA of a young boy who was killed along with his best friend Maria by GUN on a spaceship, in the third movie. The third movie will also feature Chaos and Rouge the Bat, a Mobian who emigrated to earth like Sonic and hot a job working for GUN. Both Sonic 2 and Sonic 3 will feature a variety of locations on a variety of planets as well as earth. One of them will also feature a running gag of Big the Cat just randomly showing up as a part of the group like a friggin stalker sand he will frequently suffer comedic abuse.
Also someone will see a photo of Baby Sonic and Sonic will call it “Classic Sonic”.
