As the Rat King and his new Trio of Terror—Madame Null, General Krang, and Baxter Stockman—unleash the Armageddon Game on the denizens of New York City and Mutant Town, the TMNT—under the leadership of the newly reformed Shredder—turn to allies old and new to help them in their desperate quest to stop the Rat King’s nefarious plot. Karai, Casey Jones, April O’Neil, Nobody, Alopex, Bludgeon, and Venus—each plays an important part in the apocalyptic contest for the world. But can this coalition withstand the Rat King’s latest gambit...or will a new and unexpected alliance form in its wake?

With Leonardo, Michelangelo, and Raphael away in search of new allies to join the good guys against Rat King’s latest deadly gambit, it falls on Donatello and Jennika to lead the fight in Mutant Town against Mayor Baxter Stockman, General Krang, and Madame Null. But will a dangerous quartet of masked mutant ninja turtles and a mad vivisectionist bent on revenge—not to mention E.P.F. invaders and angry Utrom soldiers!—sabotage their efforts before they can even begin to dig in?

Volume 17 includes Teenage Mutant Ninja Turtles issues #133–137, Alliance issues #1–5, and The Armageddon Game issues #1–6.
