|— A Marleyan analysis of the Cart Titan|
The Cart Titan (車力の巨人 Shariki no Kyojin?) is one of the Nine Titans with a quadrupedal form that possesses incredible speed and endurance. It is currently in the possession of Pieck. It acted as a scout and mule in Zeke Jaeger's army during the battle of Shiganshina District.
The Cart Titan stands out as unusual among the Nine Titans for its quadrupedal form, allowing for cargo and equipment to be carried on its back, which may be the source of its "Cart Titan" name. As a side-effect to inheriting the Cart Titan and staying in its form for extended periods of time, the inheritor is liable to forget how to walk bipedally and will instead crawl on all fours lke the Cart Titan. Pieck is often seen using crutches when getting around to aid her in walking normally.
The Cart Titan possesses a level of endurance far greater than that of the other members of the Nine Titans, allowing for the inheritor to partake in long missions without the need for rest. Its absorption resistance allows it to maintain its Titan form for long periods of time and wear armaments like battle armor, mobile machine gun platforms, and cargo packs for a variety of tactics, including the clearing of trenches, and long-term operations into enemy territory.
The Cart Titan also possesses great speed, similar to the Jaw Titan, which was exercised during the Battle of Shiganshina to retrieve a defeated Zeke Jaeger and Reiner Braun while also catching Levi and Hange, two of the Scout Regiment's most talented soldiers off guard.
The Cart Titan is one of the few Titans capable of intelligible speech.
The Cart Titan, like all the Nine Titans, was brought into the world after the death of Ymir Fritz. In the 1,700 years following her death, the Cart Titan was held in the possession of one or several of the warring Eldian houses subservient to the Founding Titan. After these seventeen centuries when Karl Fritz, the 145th king of the Fritz family, abandoned the conflicts of Eldia and relocated to Paradis Island, the Cart Titan was taken by the nation of Marley during the Great Titan War.
Around the year 843, Pieck was chosen to inherit the power of the Cart Titan. She would later make use of her Titan form during a war between Marley and an enemy nation, using her Cart Titan to drop off Bertholdt Hoover at a site for transformation.
Five years into the mission to reclaim the Founding Titan, Pieck's Cart journeys to Paradis Island with Zeke Jaeger and a contingent of Marleyan soldiers, using her Titan to carry supplies for them. She is present as Zeke and the soldiers transform the inhabitants of a small village into Titans.
The Cart Titan first appears during the Scout Regiment's expedition to Shiganshina District in the year 850. During the night before the arrival of the Scout Regiment, Pieck's Cart Titan keeps watch for Scouts' movement in the desolate regions of Wall Maria south of Trost District. Upon seeing the advancing soldiers, the Cart Titan returns to the ruins of Shiganshina and informs fellow Warriors Zeke, Reiner, and Bertholdt of their approach.
Later that day, Pieck's Cart Titan remains at the side of Zeke's Beast Titan, serving as a cargo mule of sorts for the Warriors' various supplies. Erwin Smith notices its presence and correctly deduces by the luggage on its back that this Titan was not among the recently transformed Pure Titans, and it must be instead an Intelligent Titan and the Warriors' scout. Bertholdt is kept hidden in a barrel atop the Cart Titan's back as a plan B against the Scout Regiment, and upon Reiner's defeat at the hands of the Scouts' Thunder Spears, Bertholdt is removed from the Cart Titan and thrown by the Beast Titan into the city. Shortly afterward, Pieck's Cart Titan fetches nearby boulders for the Beast Titan to use against the Scouts.
The Scouts choose to engage in a suicidal charge against the Beast Titan in order to buy time for Captain Levi to move in for a counterattack. As Zeke decimates the Scouts, he is quickly defeated by Levi who catches him unawares. Before Zeke can be captured by Levi, the Cart Titan comes to Zeke's rescue and carries his dismembered human form away.
Sitting atop the Cart Titan's back, Zeke guides Pieck into Shiganshina to rescue Reiner and Bertholdt. They find Bertholdt incapacitated and captured by Eren Jaeger but after seeing Levi atop the Wall, they leave him for dead. Searching elsewhere in the district, the Cart Titan rescues Reiner from capture before climbing atop Wall Maria where the Warriors are safe.
Four years later, Pieck's Cart Titan is present at the battle of Fort Slava during the climax of the Marley Mid-East War, but the use of her Cart Titan is prohibited under orders from Commander Magath, who could not risk losing a Titan to the Mid-East Allied Forces' anti-Titan artillery. However, once cadet Gabi Braun destroys the armored train carrying the artillery using explosives, Pieck is able to join the battle alongside Porco Galliard's Jaw Titan. The Cart Titan appears as an armored tank equipped with fully functional battle armor with four machine gun turrets manned by Marleyan soldiers on the Cart Titan's back, Pieck begins the assault on the trenches of the Allies and destroys their bunkers, eliminating the outer defenses of Fort Slava alonside Galliard's Jaw Titan.
During the Scout Regiment's attack on Liberio, Pieck orders the Panzer squad to prepare the Cart Titan's machine guns and uses them to fend off the attackers. The machine gun proves effective against the Scouts' ODM maneuvers and the crew is able to save the Jaw Titan from being finished off. However, one of the Panzer crew is sniped by Sasha Braus and the rest are killed by Thunder Spears. Badly injured, the Cart Titan falls to the ground, where Pieck is rescued by Falco Grice, Gabi, and other Marleyan soldiers.
- There have been crawling Titans shown before, but this is the first time a Titan walking on all fours has been seen being used to carry things.
