Cart Titan

"The Cart Titan, with its unusually high endurance, is well suited for long missions. This allows us to equip it with armaments, expanding the variety of tactics at our disposal."

- A Marleyan analysis of Pieck's Cart Titan

The Cart Titan (車力の巨人) is one of the Nine Titans with a quadrupedal form possessing devastating speed and endurance. It is currently in the possession of Pieck.

Endurance
The Cart Titan possesses a level of endurance greater than that of the other Nine Titans, allowing for the holder to partake in long missions without need for rest.

Quadrupedal form
The Cart Titan stands out as unusual among the Nine Titans for its quadrupedal form, which may be the source of its "Cart Titan" name. Furthermore, Pieck's Cart Titan has been noted as being among the faster Titan forms, alongside Porco Galliard's Jaw Titan.

Pieck
Pieck's Cart Titan is also capable of intelligible speech similar to Ymir's Jaw Titan, though not as fluent as Zeke Yeager's Beast Titan.

History
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, 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, 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 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 Bertolt Hoover at a site for transformation.

When the time came for the Paradis Island Operation, Pieck's Cart Titan was chosen to stay behind in Marley as deterrence against enemy forces.

Return to Shiganshina arc
Pieck's Cart Titan first appears within the land of the Walls during the battle of Shiganshina District. During the night before the battle, Pieck keeps watch for Survey Corps movement in the desolate regions of Wall Maria south of Trost District. Upon seeing the advancing soldiers, Pieck returns to the ruins of Shiganshina and informs fellow Warriors Zeke, Reiner, and Bertolt 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 in addition to fetching boulders for Zeke to throw at their enemies. Bertolt is kept hidden in a barrel atop the Cart Titan's back as a plan B against the Survey Corps, and upon Reiner's defeat at the hands of the Survey Corps' Thunder Spears Bertolt is removed from the Cart Titan and thrown by the Beast into the city. Shortly afterwards, the Survey Corps chooses to engage in a suicidal charge against the Beast Titan in order to buy time for Captain Levi to move in for a counterattack. Pieck ventures away from the scene as Zeke decimates the Survey Corps, only to be quickly defeated by Levi who catches him unawares. Before Zeke can be captured by Levi, Pieck's Cart Titan comes to Zeke's rescue and carries his dismembered human form away. Climbing atop the Cart Titan's back, Zeke guides Pieck into Shiganshina to rescue Reiner and Bertolt. They find Bertolt incapacitated and captured by Eren Yeager, and 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. With the battle over, the three survivors return to Marley.

Marley arc
Four years later, Pieck is present at the battle of Fort Slava during the climax of the Marley Mid-East War, but 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. Equipped with fully functional battle armor with four machine gun turrets manned by Marleyan soldiers, the "Panzer unit", on the Cart Titan's back, Pieck enters the trenches of the Allies and destroys their bunkers, eliminating the outer defenses of Fort Slava.

Trivia

 * The name of the Panzer unit, the four-man artillery crew atop Pieck's Cart Titan, is derived from the German word "Panzer", meaning "armor", specifically the armor of a heavy vehicle or tank.
