(A/N: I do not own Lord of the Rings or Invader Zim, but it would be reeeally cool if i did *large grin*)

Chapter 1:

Zim is in his lab, modifying his failed space-time object transporter device to be a dimensional warp gate. GIR, thankful that the days of having to throw his precious rubber piggies into the temporal vortex are finally over, is in the kitchen making biscuits

Zim: GIR! Get down here!

GIR: *dives into the trash can in the kitchen and falls down the elevator shaft to the lab, landing at Zim's feet. His eyes go all red* Yes, my master!

Zim: *paces around the room and begins speaking in an official tone* I'm about to go through the dimensional transporter, GIR. Needless to say it will be very dangerous, so I will be taking the Megadoomer destroyer mech with me. I'll need you to come along and plug me in.

GIR: do we have to leave now? I wanna watch the scary monkey show!

Zim: *whips out Irken disintegrator pistol and disintegrates the tv*

GIR: *cries*

Zim: when we come back, i'll take you to Krazy Taco!

GIR: *instantly stops crying* wooooo! missionmissionmission! *runs into a wall*

Zim: *sighs* come along, GIR *climbs into the huge mech* Now GIR! Open the portal!

*The Megadoomer disappears into the dimensional transporter with GIR following, carrying a large amount of extension cord*

Zim: Where are we? *looks around the cozy little village they have transported into. Several small humanoid creatures are out working in the fields*

Merry: my god pippin what is that?!?!?!

Pippin: It's one of Sauron's secret weapons!! AAAAHHH! *rolls around in the field* it's coming for me!!

Other hobbits in field: -.-;;

Zim: Quickly GIR, we've been spotted! Plug me in!

GIR: *searches frantically for a plug and when he can't find one sticks the end of the cord in the ground* there!

Zim: i'm invisible now?

GIR: *thinks for a long time* ya!

Frodo: *walks up* what manner of strange creatures are you?

GIR: taco! *deranged grin*

Zim: GIR, you said we were invisible!!!!!

GIR: um...........oops *shrug*

Zim: rrgh...oh well *hops down off the megadoomer* I am Zim, Irken Invader. What might you be?

Frodo: I'm a hobbit. My name's Frodo, and these are my friends Meriadoc Brandybuck and Peregrin Took, and - *fat hobbit carrying backpacks walks up behind them* - this is Samwise Gamgee.

Sam: Mr. Frodo, we really must be going. Gandalf said they would be coming for us, remember?

GIR: leaving? now? but i made biscuits! *on the verge of tears*

Zim: sheesh GIR calm down *turns back to Frodo* why exactly are you leaving?

Pippin: There are black riders after us and when the find us they're gonna kill us and give out our internal organs as party favors!

Zim: *long pause* kaayyy. Well, you seem in need of protection, and as i am stuck in this world of you frolicking dirt-people until i figure out how to get out then it seems the right thing to do to look after you weak filthy stink...things.

Gir: doomy doomy doomy!!!

Frodo: I think you need to have your dog checked over o_0

Zim: ya, i think so too...
