Mr. Doe and Mr. Cardholder are two secretive operatives for the Office of Secret Intelligence. They claim to be amateur lepidopterists, experts on butterflies, specifically The Monarch and his operation.
The two agents come to the aid of Jonas Venture Jr. after the Monarch is assigned to be the pint-sized Dr. Venture's arch-enemy. As The Monarch has killed almost all of his previous archenemies, the Lepidoterists have given J.J. approval to kill and brought along Brock Samson and his expertise to get the job done.
