Disclaimer: I do not owe the shows Sonic X, Sonic Underground, and Sonic Boom, the rightful owners do. The Sonics when their in each other world will go by Sonic X, Sonic B, and Sonic U.

Summary: Sonic X been battling a new foe, while in Super form, with all seven Chaos emeralds, but have to separate the emeralds to two different worlds, before his new enemies can capture it, making him fall backwards to his planet, unconscious. Before he made contact in the atmosphere, there was a bright light, making him disappear.

In the Sonic Underground world, Sonic was testing a golden ring that Trevor made, with his siblings watching, just as Sonic started to shine brightly, before disappearing in the same spot.

Also in Sonic Boom world, something bizarre was happening, while Sonic, was battling Dr. Eggman robots, he started to flicker in and out of there, Sonic then vanish into thin air as he was about to hit a robot.

"Are you a robot, made by Dr. Eggman?" Asked Knuckles, turning the blue figure attention back on him.

"Um, so if you guys are from here, then how did I came here?" Asked Sonic B crossing his arms, with narrow eyes looking at the three of them, one at a time.

"Probably the Chaos Emeralds, they do work in mysterious ways" said Tails as he suddenly saw the confusion on Sonic's B face.

"Wait, you never heard of a Chaos Emerald?" Asked Knuckles as he also saw the confusion on his face.

"What do they look like?" Asked Sonic B as Tails left the room, and return with pictures of the Chaos Emeralds.

"Here they are" said Tails giving the pictures to Sonic B, which he just stare intently at the pictures. Sonic B suddenly start screaming in pain, holding his chest in pain while laying back on the couch.
