Quest for the Chaos Emeralds in AoSTH, Secrets of the Chaos Emerald in Sonic Underground and pretty much all the time in Sonic X, past Sonic cartoons all have a Chaos Emerald saga's (except for SatAM but it did have the Blast to the Past saga with the Time Stones.) Because past Sonic cartoons had Chaos Emeralds sagas, I've come up with two-episode long adventure that still fall into traditional comedy of the cartoon series.

Part 1 is about Knuckles recieving a letter from Angel Island. Like Pre-SGW Angel Island in Archie Comics, the Echidnas are still alive, however unlike the comics the majority of the echidnas are more brawn than brain. The reason they allowed Knuckles to leave was because he was too brawn than brain, however the elders summoned him back because of his ancestry. Echidna elders tell that the eigth Chaos Crystals, each of different type and power, were each created by Ancients who protected their powers and it turns out Knuckles is actually a direct decendant of the Ancient who created the Sky Crystal, a crystal with full control over gravity and that he is now it's new guardian. Meanwhile Dr. Eggman is facinated by the power of this Sky Crystal and plans to steal it. The episode is Knuckles making a difficult choice; either to stay with Team Sonic or fufill his role as guardian of the Sky Crystal.

Part 2 is Dr. Eggman putting his plan into action and successfully steal the Sky Crystal which causes Angel Island to fall, Doctor Eggman plans to use the Sky Crystal to have his Island Lair rise so he can dominate Bygone Island. Eggman realises that the Sky Crystal can only control gravity vertically and not horizontally so decides to give Knuckles the Sky Crystal back. The Elders agree that Knuckles would be the ideal guardian to protect the Sky Crystal, but Knuckles decline the role of guardian. The elders say that it was his destiny to become guardian but accept he would be better guardian with Sonic than he would be on Sky Citadel and permit him to leave. But they tell Knuckles that there are seven other decendants of Ancients who protect the other seven Chaos Crystals.

I dunno who all the guardians will be but for sure boomiverse Blaze the Cat is guardian of the Sun Crystal.
