Teenage Mutant Ninja Turtles, Volume 15: Leatherhead by Kevin Eastman3.5 Stars.
Another of the cartoon characters, Leatherhead, makes his appearance in the TMNT comic world. Having been converted by mutagen dumped by 19th century pirates (see TMNT: Turtles in Time), hes been surviving in the Burnow Island area until the recent island upheaval by Krang and the Technodrome. The Turtles head there to oversee the re-population of the island by the surviving Utroms, as the atmosphere there is only suitable for them. Leatherhead ends up turning on them, using his brute strength to force the Turtles to help him escape, the story ending with him swimming out into the NYC harbor.
The second half of the Volume revolves around Splinter (complete with the Foot Clan at his disposal) and his battle against an uprising led by Kitsune, a sorceress who had mind control abilities. She is defeated, but manages to escape with Shredders helmet, despite wanting to take his whole skull too (still in Splinters possession).
Another great outing from the Turtles. Recommend.
The Complete History of Teenage Mutant Ninja Turtles
It is mainly based on the stories of the mutant turtles Donatello , Leonardo , Michaelangelo , Raphael , and their rat sensei Splinter. It is set in a separate reality from other TMNT stories. In their hands the comic immediately diverged from the cartoon series into unique new story arcs, often incorporating social, environmentalist, and animal-rights themes. It also introduced several new characters of various races and backgrounds, including humans, mutants, aliens, and other anthropomorphic creatures. Additionally, the series added new layers to established players such as April O'Neil , who began training with a katana, and the Shredder , who gradually revealed a sense of honor.
The pilot was shown during the week of December 28, in syndication as a five-part miniseries launching on 84 stations and being played twice a day  and the show began its official run on October 1, Since then the show and franchise has become a worldwide phenomenon. The property was changed considerably from the darker-toned comic, to make it more suitable for children and the family. The initial motivation behind the Teenage Mutant Ninja Turtles animated series was that, upon being approached to create a toy line, Playmates Toys was uneasy with the comic-book characters' small cult following. David Wise and Patti Howeth wrote the screenplay for the first five-part miniseries. Wise went on to write over seventy episodes of the series, and was executive story editor for four later seasons as well. Wise left the series partway through the ninth season, and Jeffrey Scott took over as the story editor and chief writer for the rest of the show's run.
If you were a kid in the s or 90s, you probably spent some time reading, watching, or playing with four adolescent reptilian martial arts experts with irregular DNA. If you're looking for a thorough history of the Teenage Mutant Ninja Turtles, this is a pretty good place to start. As a joke, Eastman drew a turtle standing on its hind legs, wearing a mask, with nunchucks strapped to its arms. Laird laughed and then drew a more refined version of the turtle. Not to be outdone, Eastman drew four turtles, each armed with a ninja-style weapon.
They were trained by their anthropomorphic rat sensei in the art of ninjutsu. From their home in the sewers of New York City , they battle petty criminals, evil overlords, mutated creatures, and alien invaders while attempting to remain hidden from society. They were created by Kevin Eastman and Peter Laird. The characters originated in comic books published by Mirage Studios and expanded into cartoon series, films, video games, toys, and other merchandise. The concept arose from a humorous drawing sketched out by Eastman during a casual evening of brainstorming and bad television with Laird.
