Oh dear.

Result of finally watching Repo! The Genetic Opera (which is a very, very strange movie).
So if you can imagine Zim performing a musical number as he prepares to remove his victim's organs, you're all set to go. XD
Meh, I spent about seven hours on this and there's still mistakes I couldn't fix
(I don't know if you can tell, but the binds on Dib are slightly translucent lol.)Well at least the cel-shading is somewhat satisfactory this time. XD

Probably a reference to the Dark Harvest episode as well, but with more blood.
EDIT: I forgot Zim's PAK again. ERMAGHERD! HE HAS TEN MINUTES TO LIVE, BUT THIS PICTURE'S BEEN UP FOR FOUR HOURS! IT DEFIES ALL CARTOON LOGIC! NOW I'M QUESTIONING EVERYTHING! GAAAAAAAAAAGHHHH! 
Now Dib we have been mortal enemis for to far back then I can recall. So now were shall I start how about by removing all the things that will make you scream in pain. As you can see you aren't the first one I have seen. Dib tell me have you seen your sister Gaz lately. (Zim tillts Dibs chair toward the ceiling were Gazes body hangs). And all this talk about diesection and exposeing ME now look where this has brought you. You might have had it easier if you didn't interfer oh well now we can have this little time together, your last time with me. Poor Gaz she would not haven my first if she had not been your sister. But oh don't blame your self entirely most of it was me. To bad you'll never see the armada even get here and all the human slaves bow down to ZIM. But as they say Dib love hurts and your heart will be the last thing that you will ever see. Because I'm an Irken Invader and you should know not to mess with me!
I loved the Repo movie as well. I wonder if Jhonen ever saw it.
