Eren Krueger

A covert Eldian operative embedded deep within Marley's Public Security forces, Eren Krueger carried the weight of a double life under the alias 'The Owl' and served as the architect of the Eldian Restorationist movement. To preserve his cover across the years, he was compelled to eliminate fellow Eldians with his own hands—a burden he bore alone in grim silence. As his final hours approached, he intercepted Grisha Yeager at the borderlands of Paradis, bequeathing both the power of the Attack Titan and the solemn mission to reclaim the Founding Titan. Krueger stands as the unseen hand that set the entire cycle of fate in the series into motion.
