Terra Formars: Bugs-2(2014)

Terra Formars: Bugs-2 is a sci-fi anime series set in the late 26th century, when Earth's overpopulation forces humanity to colonize Mars. After centuries of terraforming, the red planet is finally ready for settlement. But the process has triggered an unforeseen catastrophe: massive, intelligent cockroaches have evolved on Mars, and they're far more dangerous than anyone anticipated. As colonists face this unexpected threat, survival becomes the priority. The series blends hard sci-fi worldbuilding with creature horror, exploring humanity's hubris in reshaping an entire planet and the horrifying consequences that follow.
