AJ

AJ (voiced by Ibrahim Haneef Muhammad (2001–2003), Gary LeRoi Gray (2003–present)) is the resident genius in Timmy's class, and one of his best friends. AJ comes from an upper middle class, African American background. He is a straight "A" student in school, a quality both his parents have achieved as well. He has constructed an older brother who defends him from bullies, fulfilling his need for a real one. His secret lab is the greatest lab in Dimmsdale. He plays with video games and reads comic books like his other friends, in spite of his superior intellect. His relationship with Chester is stable despite having obvious contrasts. He disguises his lab with a "cloak" button on his room wall. When pressed, it converts his lab into a typical bedroom-like room.
