Tyler Tattledove aka Dr. T.

12-year-old bubblegum-chewing scientific genius revealed to be the true creator of all the devices claimed by Professor Longnecker.

Tattledove attends Sequoia Junior High School, eighth grade, and plays in the Little League.

He also has master's degree in Analytical Calculus from Chicago University and a Ph.D in Chemical Engineering from Cal Tech.

When KAOS and CONTROL compete for his services and Maxwell Smart and Siegfried have presented their best (and worst) arguments, he finally chooses the side "she" (99) is on because "she's a knockout!"

Portrayed by Peter Robbins [Episode #73: "The Mysterious Dr. T"].
