Over the years, the Teenage Mutant Ninja Turtles have grown and changed. At first, they were just some silly sketches done by Kevin Eastman and Peter Laird in 1983. In 1984, the pair of comic artists create a 40 page, black-and-white comic about their characters, giving each character a different ninja weapon to tell them apart. Two years later, the color comic came out. This had the turtles a bit taller and a little more heroic looking. Each wore a red mask, and they kept kept the weapons. The year after that, the first Teenage Mutant Ninja Turtles cartoon was released, which featured the turtles with different colored masks, initialed belt buckles, and an exaggerated love of pizza to make it more kid-friendly than the comics.
In 1990, Jim Henson produced the first live action ninja turtle movie, where the use of weapons were not allowed. That same year, Pizza Hut sponsored the Coming Out of their Shells Tour, and five years after that, both an anime and a manga were released in Japan that was based off of the “Supermutants” toy line. This series showed the turtles “morphing” like Power Rangers. Two year later, Saban produced a new TV show called The Next Mutation. It was a live action show, and also added a new, female turtle supposed to be the turtles’ long lost sister.
In 2003, a second cartoon was made. This was more related to the original comics than the first, though still kid friendly, and the character design was a more angular version of the live action design. Because putting together together a fourth live action mover proved to be too difficult, a CGI one was made four years after years after the second cartoon, and gave each turtle a slightly different look.
In 2012, Nickelodeon released a third cartoon, giving greater emphasis on the fact that they were teenagers. They were specifically designed to look as though they still had growing up to do. Two years later, a new movie was released where the turtles were CGI in a live action world. Their clothes were a mix of traditional Japanese wear and modern teenager style.
