Teenage Mutant Ninja Turtles: The Last Ronin

The series is written by Kevin Eastman and Tom Waltz, based on a story by Eastman and Peter Laird, and drawn by Esau and Isaac Escorza, Ben Bishop, and Eastman. The story follows characters from the Teenage Mutant Ninja Turtles franchise in an alternative future, wherein the last remaining turtle seeks to avenge the death of his brothers by killing the grandson of one of the Turtles' arch-enemies, the Shredder. Despite being published by IDW, it is unconnected to the IDW series' continuity and is set in its own universe, dubbed the "Roninverse". The Last Ronin was followed by Teenage Mutant Ninja Turtles: The Last Ronin - Lost Years and Teenage Mutant Ninja Turtles: The Last Ronin II - Re-Evolution in 2023. A video game adaptation, developed by Black Forest Games and published by THQ Nordic, is in development. In the future, New York City is ruled by Oroku Hiroto, grandson of the Shredder and son of Karai, running the city with meticulous fascism and totalitarianism. She finds the turtle attempting seppuku before passing out from blood loss, and wakes up to see an older April O'Neil, who identifies the turtle as Michelangelo. Flashback sequences in a sepia tone and in the style of the original Mirage comics reveal the events that led up to the present. After Shredder's death, the Turtles and the Foot Clan originally made a truce, which fell apart as Karai tried to end the conflict between their families once and for all. Mikey left New York and lived in solitude for years, accompanied by Splinter's journal, but a fight with a gang makes him realize that it is his duty as the final remaining member of the Hamato family, the Ronin, to kill Hiroto. Mikey catches up with April and meets her daughter, Casey Marie Jones, who is part of a small resistance movement and is training herself to fight the Foot Clan. As Mikey grapples with his feelings on the resistance movement, Casey's inexperience, as well as his advancing mutation, Hiroto puts the entire city under Martial Law in order to wrestle more control over it, which forces Casey Marie to gather resistance forces to stage an assault on Baxter Stockman's Fortress to disable the technology used by the Foot Clan. April, Casey, and Mikey get the remains of Professor Honeycutt to kill Stockman and send a power outage throughout the entire city. The power outage causes a flood in the sewers that threatens to drown the resistance members and April. April reveals to Casey Marie that Casey is a mutant due to the former's extended exposure to the mutagen inside the turtles.
