Gatchaman #13

As the Science Ninja Team scrambles to stop a global swarm of killer whale mechas, one ISO base is already lost—and more are on the brink. Inside Galactor, Marcus rebels against his transformation into a weapon, only to be executed by Katse as a warning: there’s no turning back. With the swarm traced to a hidden base beneath the polar ice, Jun devises a plan to strike the source—just as Galactor unleashes their deadliest weapons yet: the newly-forged Blackbirds.
