Warning: I started writing this fanfic before any episodes where Phantom and Fenton got separated were aired, so it might not match with the show. Sorry.
Danny Phantom could not believe it. He was back in the Ghost Zone! One of the places where he would rather fight Vlad Plasmius than be. All around him were doors to ghosts lairs. Suddenly, he heard a voice from right next to him.
Box Ghost: I AM THE BOX GHOST! AND YOU, CHILD, ARE TRAPPED IN THE GHOST ZONE! THE REAL WORLD IS OURS FOR THE TAKING!
Danny: Quiet! The other ghosts will hear you.
Box Ghost: THAT'S THE IDEA.
Danny: I'll just have to shut you up then.
Danny's hand started to glow green. He was preparing to fire an ectoplasm bolt. He was about to fire when a green ring wrapped around his waist and wrists, paralyzing him.
: Interfering with ghosts domination of Earth. That's against the rules.
Danny couldn't see who said that, but he knew who it was...The Warden.
Warden: Ah, Danny Phantom, we have quite a file on you, you have stopped about 8 hard-working ghosts from creating mayhem on Earth. And that's...
Danny: Let me guess, "against the rules". Right?
Danny still could only see the Box Ghost hovering three yards in front of him. He (Danny) couldn't even turn his head to look around because the paralyzing ring was still wrapped around him. (AN: If you saw the episode: Prisoners of Love, you know what I'm talking about.)
Warden: That's right. Danny: But you locked all those ghosts in your prison instead of letting them go back through the portal.
Warden: But I am the Warden. I am above the rules.
Danny: But I thought your name was William or Wallace or something.
Warden: It's Walker. But to you, I'm just the Warden. Now I'll show you to your cell, ghost-child.
Walker picked up Danny Phantom with his white-gloved hand and threw him into the back if a green, floating police car that had no wheels. Walker got into the drivers seat and...flew(?) away.
This chapter is so short that even I'm amazed by its shortness. The next ones will me longer and better written.
