The Rat King has been plotting behind the scenes of NYC and Mutant Town with his newly recruited trio of terror—LeatherKrang, Madame Null, and Baxter Stockman. As a result, his witch sister, Kitsune, and the Shredder have undertaken a desperate metaphysical journey seeking past weaknesses in order to counter the trickster god’s latest deadly gambit. Now, with Krang out of the way, Shredder and Kitsune turn their attention to Madame Null and Baxter Stockman. But will the answers they seek be even more dangerous than the arcane quest to find them? As it was in the shocking first issue, enemies become allies and exciting new characters are debuted as longtime TMNT scribe Tom Waltz returns to the pages of IDW’s ongoing series, alongside brilliant artist Fero Peniche, in this official prequel to the massive TMNT event of 2022…the Armageddon Game!
