Invader Diz is an Irken Invader. He invaded planet Phaze, and Phazon radiation caused his skin to turn blue. His PAK also serves as a P.E.D Suit, and his SIR Unit is LIR. He was cloned in the same batch as Zim, and has conquered three planets. (After the Phaze mess-up)
His skin is blue and he has purple eyes. He wears a black tunic with red strips and leggings that are yellow.
