Invader ZIM AU - Hidden Away

So basically this is an AU where Dib is an elf thing who was created when Professor Membrane was attempting to make "perfect" children through cloning. Instead of being human, a malfunction in the DNA resulted in Dib and Gaz both becoming elf things and they were the only surviving experiments so Membrane decided to keep them alive. He built a shelter in the woods to hide the children and put a disguise on, to make them believe he was the same elf things as them when in fact he was human. Then he lies to them about why he's the only one who can interact with the humans. Zim in this AU goes to Skool like normal but becomes so paranoid that the humans have begun to figure out he's an Irken, he decides to disguise himself (poorly) as a goblin from a fairy tale story he read from the Skool. He then decides to hide in the woods.
