Eren Kruger

"Watch and learn, Grisha. This is how you use the power of the Titans."

- Kruger to a shocked Grisha Yeager

Kruger (クルーガー) is an Eldian spy posing as a Marleyan soldier. To his comrades in the Eldia Restorationists, he is known as The Owl (フクロウ) and he is secretly a Titan Shifter.

Appearance
Kruger is a fairly large, well-built, older man. He has shaggy dark hair with gray in it which he keeps combed to the side. Kruger has a very slender face and pronounced cheekbones and can usually be seen wearing the standard uniform for Marleyan soldiers, although he only wears his uniform's hat when he is facing civilians.

Personality
Kruger appears to be unconcerned with the well-being of others and never shows his emotions. After finding Grisha and Fay Yeager outside of their Internment Zone, he felt no qualms in punishing Grisha physically. He again seemed to show a lack of empathy when the Yeagers learned of Fay's death, remaining stone-faced at the sight of their sorrow. However, it can be indicated that due to his job as a mole he has to behave like that to keep his identity from being exposed.

History
While spending his downtime watching blimps with one of his fellow soldiers, Kruger catches sight of Grisha and Fay Yeager following the blimp. Observing their armbands, Kruger deduces that they are from the Liberio Internment Zone. Because they had left their Internment Zone without permission, Kruger offers them a choice between hard labor or "physical punishment". Grisha chooses to take both his and Fay's punishment, and Kruger proceeds to savagely beat him. Afterwards, however, Kruger shows a hint of compassion, allowing Grisha to stay with him to watch the blimp for a while longer.

Kruger accompanies his fellow soldier to inform the Yeagers of Fay's death, and observes quietly as they grieve for Fay.

Fifteen years later, when Grisha is tortured by the army, Kruger asks if he confessed the Owl's identity. Grisha assures he does not know and Kruger announces the boat that will send the Restorationists to Paradis is ready.

During the operation, he calmly watched the Restorationists being turned into mindless Titans and chase after their comrade. As it is Dina Yeager's turn to be transformed, Kruger violently silences a yelling Grisha. When Gross is about to throw Grisha off the wall, Kruger suddenly pushes his comrade and reveal to a shocked Grisha that he is The Owl. While mutilating his hand, he teaches Grisha how to use Titan shifting ability then, in his Titan form, destroys the Marleyan boat.
