SPOILERS FROM THE SERIES:
Season 1 (November 16, 2022):
It was a great introduction to other variants of each and every single world, Sonic got some cool design from each and every world he's been, and the ending was so random. Overall, its great that we're having a Cliffhanger.
Season 2 (July 13, 2023):
Sonic and Shadow working together as a team once again made me shed a tear since I haven't seen them team up for a long time. The Chaos Powerups for Dr. Babble, Dr. Deep, and Sonic looks good but Sonic's Final Transformation was too great! But Nine ruined the whole plot of the Series, and he should've got the final shard if he already found it in the Grim. I hope both Sonic & Shadow work together again to get all of the Shards. Its not good or bad, but its average.
Season 3 (January 17, 2024):
Now that Nine became the villain of the show, His motive in creating a world just for him & Sonic was so touching when Sonic finally realized what Nine was doing all along. I became a bit sad when Sonic's Prism Energy was gone and started glitching because I thought he was going to end up like the rest of his Ghost Friends from Green Hill; And the fact that all of the variants of each & every single world met each other was so astonishing because not only they work together as a team, but they thought of each other as family, especially the Roses. The war between Sonic, Shadow, & the rest of the variants VS Nine and his Robo-Army really feels like Avengers: Endgame & Infinity War all over again. After the problem was solved, I thought there's going to be another cliffhanger like Season 1, but I think they just wanted to end it that way. Overall, the ending was a nice touch!!!
