The Invisble Man was a monster who was held captive along with B.O.B., The Missing Link, and Dr. Cockroach. He, along with Dr. Cockroach and the future Ginormica were the only monsters to have been human.


In B.O.B.'s Big Break

He entertains B.O.B. for his birthday in 1968. He mocks Dr. Cockroach's habits and multiple failed escape attempts.

In Monsters vs. Aliens (movie)

While discussing that no one can escape, the monsters reveal to B.O.B., who believed the Invisible Man escaped, that he died of a heart attack in 1984, and he is still sitting in the chair in which he died. They kept it from B.O.B. to make him feel better.
