Worlds Collide: The Blue Mask and the Cape

An anomaly in the dimensional fabric rips Leonardo out of New York City and drops him right into the middle of a high-stakes firefight in National City. Before he can even process the change in scenery, he finds himself fighting alongside Earth's mightiest heroes—Supergirl, Superman, and their elite team. Though the combined might of a mutant turtle and Kryptonians ends the mercenary threat in seconds, a much bigger question remains: who is the giant, dual-katana-wielding turtle, and how did he get here? Step into Leo's shells as he navigates a world of aliens, tech geniuses, and superheroes who have no idea what a Ninja Turtle is.
