Perhaps the most perplexing of 1980s super heroes, the sewer-dwelling, pizza-hoarding, skateboarding quartet of the Teenage Mutant Ninja Turtles has stood the test of time and remained one of the most popular children's franchises of any decade. The adventures of Leonardo, Donatello, Raphael and Michelangelo have spawned four feature films, a slew of video games, several hit TV series and a line of comic books. More importantly, the group has also been immortalized in some of the greatest toys and memorabilia of all time.
