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.
In Sonic X World
Sonic slowly opened his eyes, when he heard someone called his name. Sonic realized he is still falling, and looked in the direction of a plane coming towards him, noticing that it is the X-Tornado. Sonic smiled towards it, before noticing that he is slowly disappearing from his feet to his head.
The people on the X-Tornado also notice he is disappearing. Amy looked worry, Knuckles looked angry, and Tails looked determined.
"Tails, he is disappearing, do something!" Shouted Knuckles over the wind.
"I will as soon as we are closer to him" said Tails while flying closer to the slowly disappearing blue hedgehog, which his whole legs have suddenly disappear. Tails pressed a button on his plane, which made something appear out of the plane, and onto the disappearing Sonic.
"What did you do?" Asked Amy, worried, just as a bright light suddenly fill the sky, making the three occupants on the X-Tornado suddenly be blinded by the light.
Tails lost control of the plane a little, making it slant downwards, slightly.
"Tails!" Shouted Amy and Knuckles at the same time as they panic a little, when they felt it going downwards. Tails quickly gripped the controls tight in his hands, stabilizing it, letting out a breath he didn't know he was holding.
As the light suddenly died down, they noticed another hedgehog in the place of Sonic is falling faster to the ground below, unconscious.
Tails quickly fly the plane below the figure, while Knuckles reached out to grab the figure, catching the figure by its hands, before holding the figure tightly to his chest. Tails turned his plane around, heading home again.
Tails quickly arrived at his workshop, lowering the X-Tornado to ground, before Amy and Tails jumped out of the plane. Knuckles followed their lead, while still holding onto the hedgehog tightly to his chest.
"Put him on the couch, Knuckles" said Tails, as Tails left to get medical supplies. Amy eyes widened as she noticed something.
"Hey, he reminds me of Sonic" said Amy, as Knuckles turned towards her, not noticing the figure is slowly waking up. The figure slowly opened his eyes, taking in his surroundings.
"But his arms are not-" started Knuckles, but was interrupted by a groan. Amy and Knuckles turned towards the figure with green eyes, having shock expressions on Amy and Knuckles face.
