The story is well known: mutants, a giant rat, four brothers and the inevitable Shredder. What if there were many more elements that make the Ninja Turtles what they really are? And if Leonardo, Raphael, Michelangelo and Donatello were not the only ones to taste the amazing Mutagen? This is what you will discover in this edition of the first four volumes of the final series dedicated to Splinter's sons. Transposed straight from their feudal Japan to a laboratory in New York, they are destined to thwart the threats that weigh on the world since their legendary base in Manhattan sewers.
