Keith Shadis

Keith Shadis once stood at the helm of the Survey Corps as its 12th Commander, yet haunted by a sense of his own mediocrity, he relinquished leadership to Erwin and redirected his life toward shaping the next generation of soldiers. Season three peeled back the layers of his shared history with Grisha and Carla, revealing a man who saw himself as nothing more than a bystander watching geniuses reshape the world. His training methods were notoriously brutal, and he even covertly attempted to discourage Eren from enlisting—yet beneath that unyielding exterior lay a profound, if unspoken, devotion to those in his care and a quiet drive toward personal redemption.
