Sonic the ghost
It was a harsh battle, bombs everywhere!  Blood sweat and tears were all being forced and the battle was coming to an end. The fighters were in deep trouble. They were going to be killed by a huge laser from space. They had to save the world.
Knuckles: How are we going to get up there in time!?
Allena: We have to think!
Sonic: I know! We can use the chaos emeralds!
Tails: Sonic. You going into supersonic could kill you! You won't be able to hold back the force of that thing alone!
Sonic: And if we put the power into more than one person it won't be enough either.
Amy: Oh god you're right…
Sonic: I'm going. I'm gonna save this world even if it kills me. Which it won't. It's always better one than a million.
Daniel: Okay…
Amy: Be careful.
Shadow: You're gonna need the emeralds first.
They all passed them over and Sonic started changing. He could feel the power fly threw him. The others gave determination and Sonic confidently went into space. He flew up to the laser and held up a shield. The others could see it form below and were hopping to see success. The laser went off and the shield kept it. Sonic was being electrocuted from the power. The energy went all over the place and there was a huge explosion.  Sonic tired to fly back to earth in time. It was too late.
The others saw the destruction and cheered. They all hid from the falling objects and then noticed something incredibly wrong. Sonic wasn't back.
Cyrus: You don't think he was lost in space… do you?
Silver saw something flickering. It was a yellow glow. Silver went over to it and saw Sonic. He was severely hurt. He had blood trickling down his face, broken bones and no movement.
Silver: Guys! I need help!
Allena: What's wrong?.... My god! Sonic!
She bent over his broken body and felt for a heart beat.
Allena: He's not breathing!
Trixie: Oh my!
Tikal: Do CPR!
Trixie: Oh yeah!

After a several amount of attempts….Nothing.
Daniel: Well?!
Trixie: W-we've lost him….
Tails: What??! How?!
Trixie: I sense a harsh electric source in his heart… He got killed by the force of the field he was holding…
Cream: You mean…
Amy: Sonic's dead!?
She fell to her knees and started crying.
Amy: He can't be! I don't believe it! We have to bring him back!
Cyrus: We can try to do something. We said that we'd help anyone who is in this state. We also pledged to not give up on a dead body until a certain time.
Jet: You're right.
Matt: We'll take him to the base infirmary…

After a few days latter, there was no sign of life. The heart monitor wasn't even spiking. The fighters were in harsh guilt and grief. One of the closest people to them, one of the greatest heroes… was gone…
Manic: Bro… It won't be the same without you…
Tails: He always looked out for me when I needed help ad helped me grow up… no one can possibly take his place as the head of the resistance along with Cyrus…
Amy: I'll never fall in love again!
Knuckles: I just don't believe it…
They all had a hard time believing what they were seeing
Daniel: You're right knuckles…. I don't believe it either.

They left the room and closed it to think about what they were going to do and then the oddest thing happened.
Sonic's eyes pierced open. They were as bloodshot as ever. His spirit sat up and stretched.
Sonic: What an odd sleep!
He said while yawning. He froze and noticed he was in the infirmary.
Sonic: Ah… I'm in the infirmary… Must be pretty bad if they shut the door on me.
He got up and tried to open it. His hand went through it. He turned around and saw his dead body.
Sonic: Great! I'm dead! I knew this was gonna happen! I knew it! I have to wait now!
I've gotta tell the others.
He saw in the mirror that he had no reflection.
Sonic: This means they can't see me.

He went through the door and floated to the main base room. He saw that everyone was really upset. He saw Amy and Tails balling their eyes out. Tails was like a little brother to him and he hated to see him like this. Amy, he really loved and had made a great boyfriend for her. This made it worse. He went up to her and stroked her hair out of her face as she was head first on the table. He wanted to speak to her, but couldn't. He knew one thing. That was, they couldn't get rid of the body.
Sonic: I have to protect me… but how. In those ghost movies they do something. What is it they do?
He had it.
Sonic: I'll have to wait till tonight… Maybe I can get in a dream.

When night fell, Sonic went to the first asleep that night. This so happened to be Sonia. He went in her room and sat on the bedside. She was having trouble trying to sleep, Sonic knew this. He'd be sleepless if one of them had died.
He went up to her ear and whispered to her.
Sonic: Sonia… It's me… Sonic. I'm not dead. You have to believe me. I know you can't hear me or see me right now but I'll come back to my body in a few days! Seriously! This isn't a dream… You have to tell the others that they can't touch my dead body in any way of disposal. To prove this to you. When I'm out of my body. My eyes are open. Tell the others this. You have to tell them. I miss you

The next morning, Sonia came down the stairs and was almost crying.
Allena: Sonia… come here my baby.
She hugged her to comfort her.
Sonia: I- I had a nightmare of a sort…
Shadow: What type of nightmare?
Sonia: Sonic… I could hear him talking to me…
Daniel: It's probably because you miss him…
Sonia: No… He said something to me… I can't remember what exactly… All I remember is him saying "I'm not dead. You have to believe me." Then I kinda forgot but I remember him saying before he left. "When I'm out of my body, my eyes are open. Tell the other this, you have to tell them. I miss you"
Allena: That is really odd…
Chuck: Sonic can talk to the dead though… Maybe this is his spirit of a sort…
Trixie: What does he mean that his eyes are open?
Cyrus: His actual body… maybe…

When at base, they saw what Sonia said. Sonic's eyes were open. They weren't like this before and this was really odd.
Knuckles: Does any one feel like the word "zombie" is going to haunt us?
Tails: Sonic wouldn't have the heart to do that.
Cream: Tails is right.

That night, Sonic was able to make a wind effect and move objects. Sonic decided to
Scare the enemy. By the next morning, Eggman and Robotnick ran to their base and shouted.
Eggman: How are you doing this to us?!
Manic: Doing what?
Robotnick: I know Sonic is doing something!
Amy became tearful and so did a lot of the people there.
Allena: Sonic… is.. no longer with us… Because of your stupid plans! That stupid cannon!
Eggman: Wait, Sonic is… dead… I've lost an enemy!

Sonic watched there sorrow and couldn't help but do something to cheer his friends up. He knew the song that they were doing for the band and had the idea to show he was alive.
Sonic: Where are you? & I'm so sorry, I cannot sleep, I cannot dream tonight.(skip)
Don't waste your time your time on me, you're already the voice inside my head..
The room froze.
Rouge: C-can you hear that?
They saw a mist appear
