Invader Zuk is an Irken Invader assigned to the planet Tegprog, home of the four-eyed red people. Zuk wore a holographic disguise that fooled the Tegprogians. He let out a poison that froze all Tegprogians for a week, and when they woke up, they were slaves. After Zuk conquered Tegprog, it became known as Movietopia, the Irken movie planet. Zuk is one of the only Invaders to have orange eyes. His SIR Unit is called Junior.
