Where do the Titans Come From?
Hello everyone Flint here. Today I’m going to cover a question that many people ask and that is “What is the Origins of the Titans?” Now remember this is just a theory so it doesn’t have to believed but this is my take-on of the question. But before I begin I’ll explain some details about the Titans themselves.
The Titan threat against humanity first emerged in the year 743, destroying a heavy majority of the global human population. Some texts tell us we crossed a large body of water to reach a place prepared beforehand, containing three Walls: Maria, Rose, and Sina. However, with the Fall of Shinganshina in the year 845, the Survey Corp added on the mission of learning more about the enemy. Through information accumulated, theories on the origins of Titans and their Shifter counterparts have started to appear.
Titans are humanoid creatures that appear to be deformed and lack visible genitalia. They commonly range from 3-15 meters in height, with the Colossal Titan and the Titans Within the Walls being approximately 60 meters.
Research indicates that they have no digestive track and whatever they consume is eventually thrown up in globs of corrosive slime and human body parts. However, this process of human consumption appears to not be for caloric needs. It is assumed that due to their need for light, Titans are conductive with thermal energy, especially with their high body temperature. This also matches with their need for sunlight and the fact that few can continue on into the night if there is torch nearby.
Their bodies are abnormally light for their size and have a regenerative ability that is powerful enough to heal any wound except for an attack on the nape of the neck. Research after the discovery of Shifters has led to the theory that the reason of the nape being the only weak spot is due to the previous presence of a human pilot. Recent discoveries have revealed that the spinal column appears to be the only part of humans that survives complete descent into ‘Titan Madness’ (loss of humanity after becoming a Titan) or complete absorption into the Titan form. They also produce high levels of heat and steam, especially as they regenerate and after they’ve been killed. External sources and philosophical theories from documents grabbed by the First Squad present the possibility that a dehumanized scientist experimented with normal materials, which I shall expand upon in the next section. Using this, he changed himself into the First Titan (The Beast Titan) and turned his most loyal subordinates into Shifters.
They worked, creating a massive army that was able to almost wipe out humanity. As part of his scheme, he also created the Coordinate ability, which is the ability to control other titans. However, both this and the Shifting formula were stolen and hidden behind the Walls e.g Eren’s basement perhaps?
Due to the nature of the Titans, it is logical to assume that there is an agent involved with their creation. This agent is twofold, being both a human creator and a physiological organism that causes the change. Thus, there would also be two strains, one meant for creating the common, mindless Titan, and a second meant for the forging of Titan Shifters, likely meant to be generals for the armies of Titans that would swoop down upon the Realm of Man and destroy it.
Certain characteristics of Titans, such as expanding, heat, and steam, lines up with yeast, especially after being activated. This yeast, now airborne due to the high production rate in Wall Sina, is baked into every loaf of bread produced within the Walls. This can imply that there is a plot amongst the King and his advisors to prepare humanity for war against a force much more dangerous than the Titans or that the Titans are a means by which to create a centralized society in which the Monarchy will have complete control. Due to where the yeast is, the Ragako incident makes more sense in how the First Titan was able to turn the villagers into Titans (read chapter 51 of the manga for more information on the Ragako incident) . All of this leads to the belief that the Titan threat was manufactured by more than one party.
Science behind the Yeast-based Titan Strain theory:
a. Just like how yeast preserves the food it surrounds, so do Titans with the human they were created from. This is also supported by the case of Shifter Ymir, who spent 60 years stuck in Titan form and came out looking just like how she did when she first took on that form.
b. Yeast produces heat and gas, which is why it makes bread rise. These same two traits – heat and gas – are expelled by all Titans and Shifters, especially when they are hacked apart. Another aspect of the increase in size caused by yeast is that there is no change in mass, even though it appears larger. Experiments involving Titan limbs reveals that they are abnormally light.
c. The protein Mannose-binding lectin (Protein C) 2 or MBL, located in human blood, binds with yeast. This works into the Shifter aspect, explaining why they must spill blood in order to cause the reaction.
The yeast then uses the MBL and the extra electrical energy to produce the Titan structure. It can also bind through the porous regions around the eyes, which happens to be a common bind point for Shifters.
d. The observed rainbow strands that appear during regeneration grow in the same way as threads of yeast as it grows.
e. This only applies to Shifters, but the reasoning behind the markings beneath their eyes lies in the porous nature of the skin around the eyes. It is likely that external yeast is able to bond with MBL through the skin, which happens to leave scarring when they break out of their Titan form.
Thank you for your time and I hoped you enjoy my theory!
