Teenage Mutant Ninja Turtles is an ongoing comic book series published by IDW Publishing. Since its inception in August 2011, it has been the first new comic version of the turtles to debut after the sale of the franchise to Nickelodeon in October 2009. The initial creative team consisted of Teenage Mutant Ninja Turtles co-creator Kevin Eastman (who collaborated on the plot and the page layouts), Tom Waltz (who scripted the series) and artist Dan Duncan.
The series slightly re-imagines the origins of the Turtles, as well as other characters such as April O'Neil, Splinter and Casey Jones. It has also introduced new characters, such as Old Hob, a mutated cat, and Alopex, a mutant polar fox who begins her new life as an assassin of the Foot Clan. Notably, the series, like the original Mirage version, initially gives all four Turtles red eye masks until issue #5, where Splinter gives Leonardo, Donatello and Michelangelo their well-known blue, purple and orange masks, respectively.
