Attack Titan

"No matter the age, this Titan has always moved ahead, seeking freedom. It has fought on for freedom."

- Eren Kruger describes his Titan

The Shingeki no Kyojin (進撃の巨人) is one of the Nine Titans that has fought for Eldia over many generations. It is currently in the possession of Eren Yeager.

History
Like all the Nine Titans, the Attack Titan was brought into the world after the death of Ymir Fritz, the first of all Titans. 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. 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.

In the year 819, an Eldian spy in the Marley Public Security Authorities named Eren Kruger inherited the Attack Titan from an unknown predecessor. 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 Yeager to the island of Paradis. At the borderline, after the Eldia Restorationists were turned into mindless Titans and sent to wander the island, Kruger made use of the Attack Titan to destroy the Public Security Authorities and their ship before disposing of all evidence of the event. Afterwards, Kruger entrusted Grisha with his mission to obtain the Founding Titan from the King of the Walls and passed on his Attack Titan.

After inheriting the Attack Titan from Kruger, Grisha used his Titan to head northwards towards the Walls, where he was found by soldier Keith Shadis of the Survey Corps. After his arrival in Shiganshina District, it is unknown how often Grisha made use of his Attack Titan.

After holding the Attack Titan for thirteen years, Wall Maria came under attack by the warriors of Marley, and Grisha decided the time had come to negotiate with the Founding Titan or take it by force. Arriving at the Reiss Chapel, Grisha pleaded with Frieda Reiss for the sake of Eldia and the Walls, but his cries were neglected. Left with no choice, Grisha used the Attack Titan against Frieda's Founding Titan and overpowered her, stealing her Founding Titan and killing her along with the rest of her family excluding her father, who escaped.

Upon returning to Wall Rose where the refugees from Wall Maria were arriving, Grisha found his son Eren Yeager and took him into a forest where he injected him with a Titan serum. As a mindless Titan, Eren ate his father and inherited both the Attack Titan and the Founding Titan, though he could not use the latter due to his non-royal lineage.
