The TMNT have been around for a long time and have been known to have fans from all age groups.
So who are the TMNT? They are the Teenage Mutant Ninja Turtle who have been fighting crime since their conception in 1984 when illustrators Kevin Eastman and Peter Laird drew a turtle dressed in ninja garb.
Later when Mirage Studios accepted to print their story in a comic book form of a gang of teenage turtles who had been trained by a sensei (who incidentally is a rat )in the art of ninjutsu, the TNMT became a rage that quickly jumped from the print to the screen, into toys, video games and various other merchandise.
