Plot

In a typical Jonny Quest plot device, a well-meaning scientist's experiments go horribly awry. This time around, Dr. Isaiah Norman has created an invisible monster made of pure energy. The Quests try to exert a large measure of damage control as the monster goes on a rampage, absorbing everything -- and everyone -- in its path. John Stephenson, the original voice of Dr. Benton Quest, is here heard as the benighted Dr. Norman. "The Invisible Monster" originally aired on January 28, 1965.
