Rocksteady

Few crossover events are as gleefully unhinged as the 2016–2017 IDW mashup that brought Rocksteady crashing into a world where Gotham's shadows meet the sewers of New York. Debuting in Batman/Teenage Mutant Ninja Turtles Adventures #2, this Modern Age incarnation was brought to life by Matthew K. Manning and Jon Sommariva, and shares chaotic pages with the likes of Michelangelo, Leonardo, Donatello, Batgirl, and even The Joker — as wild a roster as comics can offer. With only four catalog appearances, Rocksteady's presence here is a compact but memorable one, perfectly suited to a series built on the pure, joyful absurdity of two beloved universes colliding. For collectors who love their crossovers loud and their rosters wonderfully unexpected, this is a corner of Modern Age comics worth tracking down.
