Tom Wade was a drifter who stumbled onto the home of Dr. Cortell, a retired scientist. The scientist took pity on the young man and made him a research assistant. Together, they developed a formula that could make anyone invisible. When Dr. Cortell died of natural causes a few days later, he entrusted Tom with safeguarding the formula. But when a mercenary named De Pix kidnapped Dr. Cortell's children, he used the formula to rescue them and bring the criminal to justice. He turned the formula over to the U.S. government, but he kept a copy in order to continue fighting crime as the mystery man known as the Invisible Terror.

Tom was assisted by Dr. Cortell's children - Nancy, Jack, and Jerry.

Dr. Cortell's formula made the person who injected it temporarily invisible. The duration of invisibility is directly proportional to the dosage - the more formula a person ingests, the longer it will last.
