AN: I don't own Invader Zim. I'm writing this because I love IZ truth or dares. I'm writing this with a friend of mine, so the updates may be kind of slow.

*the IZ cast is sitting on a nice couch in a well decorated room*

Dib: Where are we? *gets up from couch* Where's the door? *starts looking for a door. All of a sudden, a piece of wall slides open.* What the?

A tall girl about the age of 13 in a Kiss T-shirt and jeans with black hair and red eyes walks through the piece of wall that slid open.

Kieran: You should have stayed on the couch, Dib.

*Kieran is walking towards Dib. Something about her makes Dib back away cautiously and, unknowingly, into a corner.

Kieran: I've never had the pleasure of drinking the blood of a paranormal investigator as young as you Dib. Oh, I've had many try to best me, but they all wound up donating blood to me.

Dib: You're a vampire!

Kieran: Yes. Oh, and look, you've forgotten to bring your wooden stake. It makes no difference. Even if you had something wooden I could disarm you in the blink of an eye.

Another girl walks through the panel of wall. She's the same height as Kieran. She's wearing a Kiss T-shirt and jeans too. Her hair is black too and her eyes are dark blue. The wall panel slides closed behind her.

Muse: Kieran! Stop scaring the poor boy!

Kieran: Muse! You know you're not the boss of me.

Muse: Can't you just listen to me for once? We are sisters after all!

Dib: Another vampire!*Dib is looking around trying to find a way out.*

Kieran: Don't waste your time. These walls are sound proof and the only way to open the panel in the wall is with a spoken password AND it has to be a registered voice. Face it, you're trapped!

Red: I demand you let us out now!

Kieran moves swiftly to him with the grace of a predator.

Kiearn: I've never tasted alien blood either. I hear it's delicious though.

Kieran leaned closer and closer to Red as she spoke. Red started looking very nervous. After she finished talking, she quickly pulled away.

Kieran:Now, the reason you are all here is...

Muse: Hey! You promised I could tell them!

Kieran: Fine.

Muse: You are all gathered here for another IZ truth or dare!

Cast: Not another one!

Kieran:Yes another one! Now shut your noise tubes! Now, we have a twist. Guest stars! Each chapter there will be a character from another show. Unless, of course, I can get fanfic authors to guest star. I would like to do that. I may even invite some of you who review to guest star. We have every IZ character here. Except minimoose. Sorry. Keef is here. He's locked in a closet though because his sunny attitude makes me sick! One more thing about the guest stars. If YOU have a charcter you would like to see as a guest star just let me know and I'll see what I can do. Now, I'm getting kind of hungry so I'm gonna leave and get a steak. Mmmmmm, steak.

Muse: See you next time!

AN: I know. It's pretty bad, but I didn't have anything to make them do. It will be more interesting after I have some reviews.
