Cart Titan (Anime)

The Cart Titan (車力の巨人) is an Intelligent Titan with a quadrupedal form acting as a mule in Zeke's army.

Quadrupedal form
The Quadrupedal-type Titan stands out as unusual among the Intelligent Titans for its quadrupedal form, which may be the source of its "Quadrupedal-type Titan" name.

Return to Shiganshina arc
After the Beast Titan and his army transform, the Quadrupedal Titan can be seen among them acting as a mule-like Titan carrying crates and barrels strapped to its back. When Erwin Smith sees this, he believes this Titan isn't with the rest of the army. Instead, he theorizes that this Titan has intelligence and acted as a scout to warn Reiner Braun of their incoming approach.

Trivia

 * 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.
