"The Invisible Monster"Edit
Dr. Isaiah Norman was a colleague of Dr. Quest who was working with molecular energy on Cave Island. His experiments resulted in the creation of the living mass of energy, which escaped his laboratory and ran amok on the island. Dr. Norman managed to get a call to Dr. Quest, asking him to come and help.
In the middle of Norman's call to Quest, the invisible monster returned and absorbed the scientist.
Dr. Norman was voiced by John Stephenson.
