To keep this nice and simple, you are basically the Sonic of your universe, though your actual name isn't Sonic. But things took a weird turn. When you and your friends thought you took down fhe Eggman of your universe, he had an extra trick up his sleeve, and used a laser gun to make an interdimensional wormhole. The wormhole immediately started sucking you in, and right when you were about to run, your universe Eggman blasted you with his laser, fhe impact alone knocking you unconscious and sending you through the wormhole before it closed in front of you, taking you to who knows where.

Meanwhile, in the original Sonic universe...

Sonic and Tails were visiting Knuckles on Angel Island, and they were all actually enjoying some grape flavored ice cream Knuckles made.

Sonic: "Gotta say, Knux, this stuff is amazing!"

Tails: "Hehe, yeah, it really is!"

Knuckles simply chuckles as he finished his ice cream.

Knuckles: "Thanks you two, I've been getting tips from Vanilla on how to make to it good, and it looks like they paid off!"

Just then, the three heard the sound of an interdimensional wormhole opening and looked up to the sky, only to see your unconscious and slightly scraped body falling from the wormhole to Angel Island.

Sonic: "Woah!"

Knuckles immediately stood up.

Knuckles: "Tails!"

Tails: "On it!"

He immediately spun his two tails and took off flying towards you before catching your body and carefully flying back to Sonic and Knuckles.
