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

"Hey, Tails, Amy said you wanted to see me" said Sonic, while walking up to Tails, who is holding something in his hands.

"Yes, something is going on in space, and we need you to check it out. So I build a earpiece that we can communicate with each other, and you won't actually have to fight alone this time, because we will come to the rescue, if you need it." Said Tails, handing the earpiece to Sonic, who put it on his ear.

Sonic was about to leave in the Hyper Tornado, but was stopped by Knuckles, who had enter the room, with the seven Chaos Emeralds.

"You're going to need these, and if you lose them again, I will kill you." Said Knuckles, handing the Chaos Emeralds to Sonic, who grabbed them, turning into Super Sonic, and giving Knuckles a thumbs up.

"Sorry, but I can't help it" Said Super Sonic, while flying up to dodge a swing of Knuckles fist.

"Sonic, please be safe" said Tails, while Super Sonic, lowered to the ground to face Tails.

"Let's hope it is not as bad as the Metarex, last year, pal." Said Super Sonic, giving another thumbs up to Tails, before flying upwards, and making a hole in the roof.

"Why can't he just use the door, like a normal person" said Knuckles in a grumpy voice, as Tails looked up at Super Sonic, who is starting to disappear in space, from the hole in the roof.

Meanwhile in space, Super Sonic, looked around, what looked to be a whole army, led by a thing that is half plant on one side, and half metal on the other side.

"Greetings, Sonic the Hedgehog, I have heard great things about you, and your little friends" said what sounded like a female in front of the whole army.

"Well, I haven't heard about you that much, aside from trying to conquer my planet" said Super Sonic, getting in a position to fight her.

"Now, now, all you had to do was ask" said the woman, smiling creepily at Sonic.

"Ok, who are you guys?" Asked Super Sonic, not noticing that a plant vine is sneaking behind him, slowly wrapping its vine around his ankle.

"I'm the Great Dark Thorn, and these are my Commanders, and the Latarex. We were imprisoned, until last year, when you defeated the Metarex, or should I say, your friend Cosmo" said Dark Thorn, as Super Sonic, glared at her, while clenching his fist to his side. Just as he was about to attack Dark Thorn, he felt like something is holding him back. Super Sonic looked down, and noticed a glowing vine is wrapped around his ankle, making him feel a little weak.

"I see you're draining my energy" said Super Sonic, as he started to flicker in and out of his Super mode.

"No, not your energy, but your life force, only enough for you to pass out, and could capture you, and the Chaos Emeralds." Said Dark Thorn, while Super Sonic, starting to breathe heavily. I got to break out of this vine, so she wouldn't get the Chaos Emeralds, but how, thought Super Sonic, before his eyes light up, as he thought of an idea.

Super Sonic quickly use spin dash to break out of the vine hold. Super Sonic touch his earpiece that Tails gave him, contacting Tails, from his workshop.

"Hey, pal, are you there?" Asked Super Sonic, keeping his eyes on the enemies, that is slowly surrounding him.

"Yeah, Sonic, I'm here, with Amy, and Knuckles" said Tails turning his communication device on speaker so Knuckles, and Amy can hear Sonic, from his side.

"Hey, Knuckles, sorry but I have to do it again, also Tails, and Amy, I'm sorry that I am not going to be okay" said Super Sonic, as he disconnected the call, tossing the earpiece away, before they said anything.

In the workshop with Tails, Knuckles, and Amy all they heard was static on their side.

"We gotta rescue Sonic" said Amy, marching towards the Hyper Tornado, with Tails and Knuckles following her.

"Wait Amy, it might be too late, and we should think of a plan to get Sonic back." Said Tails, but pause in his walking, with Knuckles following his example, as Amy slowly turn towards them, with fire in her eyes.

"I don't care, Sonic needs me" said Amy, now with tears in her eyes.

"I know, but we will figure it out, together, Amy" said Tails, walking up to Amy, and giving her a hug, which she returns, while Knuckles looked towards the sky, where the hole in the roof is at. I hope you're alright, Sonic thought Knuckles, before looking at the two hugging friends.
