Teenage Mutant Ninja Turtles ( TV Series 1987 - 1996 )





 

Plot



The Teenage Mutant Ninja Turtles (or simply Ninja Turtles) are a fictional team of four teenage anthropomorphic turtles, who were trained by their anthropomorphic rat sensei in the art of ninjutsu and named after four Renaissance artists. From their home in the storm sewers of New York City, they battle petty criminals, evil megalomaniacs, and alien invaders, all while remaining isolated from society at large. The characters initially appeared in comic books before being licensed for toys, cartoons, video games, films, and other merchandise. During the peak of its popularity in the late 1980s through early 1990s, the franchise gained considerable worldwide success and fame.



 

Teenage Mutant Ninja Turtles originated in an American comic book published by Mirage Studios in 1984 in Dover, New Hampshire. The concept arose from a humorous drawing sketched out by Kevin Eastman during a casual evening of brainstorming with his friend Peter Laird. Using money from a tax refund together with a loan from Eastman's uncle, the young artists self-published a single issue comic intended to parody four of the most popular comics of the early 1980s: Marvel Comics' Daredevil and New Mutants, Dave Sim's Cerebus, and Frank Miller's Ronin.





Characters

 

 

Leonardo (Leo)  The courageous leader and devoted student of martial arts, Leonardo wears a blue mask in some versions and wields two katana. He is the oldest of the four and the most skilled fighter of the turtles. Leonardo was named after the Italian polymath, scientist, engineer, inventor, anatomist, and painter, Leonardo da Vinci.



Raphael (Raph)  The team's bad boy, Raphael wears a red mask and wields a pair of sai. He has an aggressive nature and seldom hesitates to throw the first punch. He is an intense fighter. He would usually speak in a Brooklyn accent. His personality can be alternately fierce and sarcastic, and oftentimes delivers deadpan humor. Still, he is intensely loyal to his brothers and sensei. Raphael is good friends with Casey Jones. He is named after the Italian painter and architect of the High Renaissance, Raphael.



 

Michelangelo (Mike or Mikey)  Easy-going and free-spirited, Michelangelo wears an orange mask in some versions and wields a pair of nunchaku. Michelangelo provides much of the comic relief. While he loves to relax, this Turtle also has an adventurous and creative side. He's something of the "surfer" boy, speaking usually in a Southern California accent. He is named after the Italian Renaissance painter, sculptor, architect, poet, and engineer Michelangelo Buonarroti. His name was originally misspelled "Michaelangelo" by Peter Laird and Kevin Eastman.



Donatello (Don or Donny)  The knowledgeable scientist, inventor, engineer, and technological genius, Donatello wears a purple mask in some versions and wields the bō staff. Donatello is perhaps the least violent Turtle, preferring to use his knowledge to solve conflicts. He is named after the sculptor Donatello.



 

Splinter  The Turtles' sensei and adoptive father, Splinter is a Japanese mutant rat who learned the ways of ninjutsu from his owner and master, Hamato Yoshi. In the 1987 TV series and Archie Comics series, Splinter was Hamato Yoshi mutated into a rat instead of being just Yoshi's pet.

Shredder  A villainous ninjutsu master called Oroku Saki. In every incarnation of the TMNT franchise, he has been the archenemy of Splinter and the Turtles. Shredder prefers to use his armor instead of weapons in some versions. He is also the leader of the Foot Clan.



 

April O'Neil  A former lab assistant to the mad scientist Baxter Stockman, April is the plucky human companion of the Turtles. April first met up with the Turtles when they saved her from Baxter's Mouser robots. She embarks on many of the Turtles' adventures and aids them by doing the work in public that the Turtles can not. In the 1987 TV series, Archie Comics series and subsequent three films, April was a television news reporter.

​

Casey Jones  A vigilante who has become one of the Turtles' closest allies as well as a love interest to April. Casey first met up with the Turtles after having a fight with Raphael. Casey fights crime with an assortment of sporting goods (baseball bats, golf clubs, ice hockey sticks, cricket bat, etc.) while wearing a hockey mask to protect his identity.
