Anthony James "A.J." Jr is a major character in The All New Fairly OddParents!, and a major adult character in The Fairly OddParents: The Next Generation. He is one of Timmy Turner's best friends. A.J. is shown to be extremely intelligent (smart) and rich, but is not very good at social skills, and as a result, he is considered an unpopular child like his two best friends, Timmy Turner and Chester McBadbat, at Dimmsdale Elementary School.
He is bald, and wears a light blue sweater vest, which is describe as a "girl magnet", over a white shirt. He also has grey pants with black shoes. His pupils are colored blue. A.J. is around the same height as Chester and Timmy.
A.J. is much smarter than any other student, and this sometimes causes friction between him and his less intelligent friends, as he often flaunts his intelligence to the point of arrogance. A.J. is a fan of Crimson Chin and Crash Nebula, although he seems to prefer Crash Nebula more and sometimes argues with Chester over who is better. He has a secret lab in his bedroom which he uses to create clones, inventions, and conduct scientific research. A.J. is so intelligent that the government has sought him out for his technical assistance. It has also been seen that he can make anything out of anything.
