J.D. is an African-American who was adopted by Jack and Helen. He possesses one of the top analytical minds in the world and is constantly inventing new devices for the Bionic Six to use. He is often found helping Prof. Sharpe in the SPL. J.D. is constantly working on experiments during his free time, and also enjoys a good mystery. He also has a good heart and often plays the good samaritan. As I.Q., J.D. was given super-strength (beyond that of the other members). Oddly enough, he doesn't have the -1 suffix for his bionic form. He often acts as the Six's tactician, providing inspiration on the battlefield.
