The grayish Irken named Zim wore his human disguise as he walked down the hallways of Skool, in which he had to take part of in order to study the human races weaknesses for the Irken Armada. You've noticed him sometimes; well it was hard not to notice him considering his oddly green pigmented skin, his lack of ears and a nose.. but no one else seemed to care. Now, Zim sat in his usual seat in class, a very annoyed look on his face as he leaned forward in the seat and messed with a pencil between his three fingers.
