At the borderline, after the Restorationists were turned into Pure Titans and sent to wander the island, Kruger made use of the Attack Titan to destroy the Public Security and their ship before disposing of all evidence of the event. During the thirteen years he held the Attack Titan, it is unknown how often he used it, if at all, until the year 832 when he brought Grisha Jaeger to Paradis Island.

In the year 819, an Eldian spy in the Marley Public Security named Eren Kruger inherited the Attack Titan from an unknown predecessor. During the Great Titan War as Marley gradually gained control over seven of the Nine Titans, the Attack Titan evidently never fell into Marley's hands and remained on the mainland while the Founding Titan remained overseas on Paradis Island where the 145th Fritz King, Karl Fritz, relocated the capital. Though this Titan was presumably caught up in the conflict of houses between the eight Titans of the Eldian Empire subservient to the Founding Titan, it is said that the Attack Titan always fought for the freedom of Eldia no matter the day and age. The Attack Titan, like all the Nine Titans, was brought into the world after the death of Ymir Fritz. Grisha Jaeger knew of the Founding Titan's bloodline restriction from the future memories of his son, Eren. Eren Kruger received memories of Grisha Jaeger telling his son to protect Mikasa Ackermann and Armin Arlelt, although he did not know whose memories they were. These memories led those with the Attack Titan to move forward, fighting for freedom. While all of the Nine Titans could receive memories of past inheritors, the Attack Titan could also receive memories of inheritors yet to come.
