AlluraTheTitan
Just months after the Multiverse mayhem, Sonic and his friends face a new threat: an alien titan burdened by power, scars, and a story none of them are ready for.
Disclaimer: The series "Sonic's Green Hills Adventures" doesn't belong to me. This is just my own continuation of the story. Go check it out JackxSally4 https://www.wattpad.com/user/JackxSally4 and read the other 5 seasons or listen to them on her Youtube Channel (https://www.youtube.com/@MarinaMelody-sw1ck). Reading the other seasons will help you understand the other human characters in the story.
