LISTEN HERE AND LISTEN NOW, EARTHSCUM! I'M TELLING YOU POLITELY TO NOT MESS WITH MY PROPERTY,THANK YOU! ~Miz
Zor is, in a way, like Zim's older brother. And on Earth is his older brother. He is more mature and blends in with the humans more than Zim. But he has some of Zim's traits, with bad listening and day-dreaming of being the best invader.
He has purple eyes with a blue and white Invader uniform. In his disquise he has changed his skin color to those of a human tone though he still doesn't have ears. He wears glossy blue contact lenses of Zim's color. And he disguises his invader outfit as a sleeveless basketball player like shirt with the Irken symbol on the front,baggy jeans,and black shoes. His wig is the same as Zim's making them look more like brothers.
Zor and Zim are like brothers either way. Zor is sent to Earth to destroy Zim so he never returns back to Irk but they soon are found and lie as saying they're brothers,over time sometimes Zim and Zor forget they really aren't brothers and act brotherly to each other anyways.
Zor like Zim is Dib's enemy. Dib soon finds out Zor's real identity and replies as saying 'Now they're's two OF THEM!'. Like Zim he wants to expose Zor of his real self.
They know each other. She likes Zor as a friend for Zim's sake.
Zor feels quite bitter about humans, but also is interested in their existance. So he, like Miz, is respectful to them.
