Subjects of Ymir being injected with Titan spinal fluid Subjects of Ymir are all distantly related to her, connecting them to the paths which enables transformation. Ymir Fritz was the first Titan, who became one after merging with a strange spine-like creature in a tree. However, some Abnormals were also able to sustain some of their former intelligence, such as Connie's mother and the Titan encountered by Ilse Langnar, both of which demonstrated the capacity to form thoughts and even communicate with humans.Īll Titans were originally humans of a race of people called the Subjects of Ymir. The Nine Titans were the exception: they had human level intellect due to being piloted by a human. Most Titans showed no signs of intelligence and acted like mindless beasts-easy to trick, distract, and deceive. After consuming a certain amount, they regurgitated the contents of the cavity before they continued eating more humans.

Titans did not possess a complete, functioning digestive tract they merely had a stomach-like cavity that eventually filled up with what they swallow. Some Titans did not react to pain, and all would move as long as there is sunlight. They did not derive any real sustenance from humans either, as many of them did not taste human flesh for a century after the Walls were raised but it did not affect their activity or decrease their numbers.

Unlike other species, Titans did not mate, and their interactions were nonexistent with organisms other than humans their sole purpose in life was to seek out and devour humans. The vast majority of Titans had a masculine body type, although all of them lacked reproductive organs. The vast majority of Titans had exceptionally wide mouths with an array of entirely sharp (in certain instances), or entirely flat teeth (which was more common in most observed titans). They were typically bipedal, though a few were quadrupedal, with the limbs and features one would expect in humans however, they were all deformed to some extent in body proportions (enlarged head, small limbs, etc.).
