Fans of the Teenage Mutant Ninja Turtles got a bonus lesson in Renaissance art thanks to the heroes in a halfshell, inexplicably named after some of history's most revered artists. The pizza-loving, crime-fighting quartet of turtles came in hundreds of different variations, from the classic ninja varieties to farmer, military, Wild West and classic movie monster varieties. The turtles also came with some truly awesome playsets, including a party wagon, blimp, and the totally tubular Technodrome, home of villans Krang and Shredder. You could also purchase the turtles' sewer playset -- because what kid doesn't want to play in the sewer?
Where They Are Now: The Turtles seem to have never gone out of style, and a series of video games, comic books, toys and CGI and live-action movies have been released over the years. A third animated series and its accompanying toy line debuted on Nickelodeon in 2012.
