Picking up years after the Survey Corps reached the sea, The Final Season dramatically shifts perspective, initially focusing on the nation of Marley and Eldian Warriors like Reiner Braun, revealing the global conflict surrounding the Subjects of Ymir (Eldians). As Eren Yeager and the Survey Corps infiltrate Marley, the lines between hero and villain blur irrevocably. Eren inherits the War Hammer Titan and embraces a radical path, ultimately seeking to activate the 'Rumbling' – unleashing the millions of Colossal Titans within the Walls to trample the world outside Paradis. Former comrades are forced to choose between loyalty to Eren and saving humanity, leading to a devastating global conflict and a final, desperate battle against their former friend to stop the apocalypse.
