Agent J

The Men In Black animated series was based on the first Blockbuster film where the role of Agent J was played by Will Smith. The series continued the story that began in the movie with Agent J, while increasingly capable, still providing much of the comedy as he never quite measured up to Agent K and was often kept out of the loop.  Check out the intro:

The Jackson 5ive

The Jackson 5ive was the Saturday morning cartoon series that provided a fictionalized story of the career of the Jackson 5: Jackie, Tito, Jermaine, Marlon and Michael. It's a bit of a shame that none of them were actually in it. In the shows opening the faces of the Jackson 5 are morphed into cartoons but they did not provide the voices of the characters or contribute to the show in any way. Their music was used as well as some concert footage but that was it. It didn't matter anyway because the show was a hit. It aired for two seasons from September 1971 to September 1973. Here's the intro:

Harlem Globetrotters

The first Harlem Globetrotters series called "Harlem Globe Trotters" debuted in September 1970 and ran through September 1972. It has the distinction of being the first Saturday morning cartoon that featured African-American male characters. The animated cast featured George "Meadowlark" Lemon, Freddie "Curly" Neal, Hubert "Geese" Ausbie, J.C. "Gip" Gipson, Bobby Joe Mason, and Pablo Robertson. Also included in the show was Granny (who drove the bus and kept them in line), and Dribbles the dog. Check out the funky opening sequence:
