Dib is obsessed with the paranormal and supernatural, which allowed him to recognize the alien in the classroom almost instantly. Everybody always tells him that he’s “crazy” or “insane” and doesn’t pay attention to the information Dib has. In just about every episode Dib tries to show Zim as he really is and often fails. He is also very sensitive about the size of his head and gets emotional when one points it out. He often tries to be sneaky about trying to infiltrate Zim’s plans but gets caught almost instantly unless he has a super awesome gadget to help him get away.
