Titans are a race of giant man-eating humanoids that serve as catalysts for the events in the series. They first appeared 107 years prior to year 850 and had rapidly exterminated humanity to the point of near-extinction.
Titans greatly resemble nude humans. They are typically bipedal with the limbs and features one would expect in humans; however, they are all deformed to some extent in body proportions (enlarged head, small limbs, etc.). Many Titans have exceptionally wide mouths with an array of square teeth. The vast majority of Titans have a masculine body shape, although all of them lack reproductive organs. Behaviour
Unlike other species, Titans do not mate, nor interact with organisms other than humans; their sole purpose in life is to seek out and devour humans. They do not derive any real sustenance from humans either. Titans do not possess a complete, functioning digestive tract; they merely have a stomach-like cavity that eventually fills up with what they swallow. After consuming a certain amount, they regurgitate the contents of the cavity before they continue eating more humans Some Titans do not react to pain and all will move as long as there is sunlight. Most Titans show no signs of intelligence and act like mindless beasts; easy to trick, distract, and deceive.
The body of Titans appears to violate several known laws of science, spontaneously generating both energy and mass. Their bodies are incredibly light, allowing them to stand and walk despite their size. Their extremely high level of activity and body temperature indicates the need for a massive intake of energy to fuel them, yet they apparently never need to eat at all, though most Titans kill their victims by appearing to do so. They possess and use vocal organs, but they do not need to breathe for survival. Titans draw their primary source of energy from the sun, as they become inactive when deprived of sunlight. The absence of sunlight affects individual Titans differently. Titans possess incredible regenerative abilities. Although it varies from Titan to Titan, they can regenerate lost body parts from seconds to minutes, even severed heads (unless the nape is severed with the head). The only known sure-fire way to kill them is by slicing an area one meter long and 10 centimetres wide on their nape. Without a functioning nervous system to control it, the Titan dies. After death, Titan corpses rapidly evaporate to skeletal remains, then to nothing at all. How Titans react to pain stimuli varies from one to another: Some Titans completely ignore agonizing injuries, even impalement through the heart, and attack nearby humans as normal. Others scream seemingly in agony.
An "Abnormal" is an uncommon type of Titan which can possess unusual intelligence or perform unpredictable actions. Unlike the typical Titan which attacks and devours humans on sight, abnormal Titans may choose to ignore lone or isolated humans and exhibit unpredictable behaviour; often resulting in them causing larger damage as they disrupt important strategic locations. Some of these uncommon behaviours are speed-walking or running, performing great jumps, and even speaking human language
