Shingeki No Kyojin (Attack On Titan) is indeed one of the most popular anime and manga at the moment. The title itself already shows who the main antagonists are in the anime and in the manga. The Kjoyin or Titans are a mysterious race of humanoid giants which appeared roughly 107 years ago. They have rapidly increased and have exterminated humanity to the point of near extinction. However, their origins, overall population and how their body works still remains a mystery at the moment. Although humans have tried to study them, there just seems to be too much information that needs to be known about them. Although Titans greatly resemble human beings because they are also bipedal and have the same number and arrangement of limbs and other physical features, their proportions vary. Some of them have large heads, longer arms and so on. Apart from that, there are other abnormalities like some lacking skin and tissues however, they do not bleed from these deformities. Most Titans are also males however, they lack gonads therefore, their method of reproduction is still unknown and is yet to be discovered by the humans who study them. Titans have complete set of teeth except that they do not have sharp fangs like canines and they also do not have a complete and fully functional digestive tract. Their favorite activity is eating humans however, when they cannot eat anymore of them, they throw them up or extract them from inside their bodies to make room for more.

However, not all Titans are pure. Some Titans are actually humans who change into Titan forms. This is actually a twist in the story which most people did not expect. Eren emerging from the body of a Titan gave birth to the idea of Titan Shifters. Titan Shifters are types of Titans that are controlled by humans. Somehow, some humans are capable of transforming into Titans and they possess various unusual traits an skills that they can hone and even direct with a purpose. Titan Shifters are unusually stronger and/or faster than typical Titans and they can also retain their intelligence during controlled transformation. However, this is not the case if the transformation is not controlled. One’s intelligence depends on the capability and training received by the person who is going to transform into a Titan. Luckily, Titan Shifters don’t have any deformities that hinder their skills and they often resemble their human drivers. Like Titans, Titan Shifters can also regenerate parts of their body by focusing.

So far, there are five known Titan Shifters in the series. The first Titan Shifter known in the series is Eren Jaeger’s Berserk Titan. Despite his substantial physical strength and his use of martial arts techniques, his greatest disadvantage is that he doesn’t know how to control his transformation well yet. It is still unknown as to how far his abilities would go but right now he is still pretty unstable which is why people still find it hard to trust him. Other Titan Shifters include the Dancing Titan. Later on, it will be revealed that Ymir transforms into the said monstrosity. Her Titan has sharp teeth and claws which helps her easily hang on walls and are good for combat. She is the smallest Titan Shifter at the moment. Next is the Colossal Titan which is the largest of all the Titan Shifters at the moment. Although it moves slowly, it compensates it by its degree of intelligence and tactical planning. It is also very strong as it can break down walls. Later on, it will be discovered that Bertholdt is the said Titan Shifter. The Armored Titan is also another example of a Titan Shifter. This Titan Shifter has hard skin all over its body, has advanced strength and agility and is somehow well-built. Like the Colossal Titan, the Armored Titan can also destroy walls. This Titan Shifter is actually Reiner. Lastly, we have the Female Titan. She has already appeared in the series too and is currently the Titan Shifter that everyone is looking for. She is the only Titan Shifter with a female form. Out of all the Titan Shifters, she is the most agile and the most intelligent of them all as she is not keen on eating any humans and would rather just kill those who are considered a threat to her. Like the Armored Titan, she also has the ability to harden parts of her body which allows her to protect certain body parts, most of all, her neck. She can even call other Titans just by her loud call. Although, there have been speculations only at the moment, later on, it will be revealed that the Female Titan is in fact, Annie.

It is unknown if there will be more Titan Shifters that will be introduced in the series. After all, it is still ongoing. There are many mysteries behind the walls and there are also enemies inside the walls that people need to find out. As the series continues to progress, more and more secrets will be revealed and more and more blood, violence and gore will ensue. Death is inevitable at this point and somehow it is hard to say if those who have lived and survived are considered lucky. To fall prey to flesh eating giants isn’t exactly any different from surviving a zombie apocalypse and trying to avoid being consumed by them. The only good thing about being eaten by a Titan is that you will never turn like them. Not like when you get bitten by a zombie, surely, you will become one of the undead. But there are still so many things that needs to be revealed, so many things that needs to be learned. Will the humans will the war against the Titans? No one knows. Which side will the Titan Shifters choose? For now, it is safe to say that Eren is on humanity’s side but the rest are still on a different side. Will he be able to persuade them to join his cause or will he have to defeat them and kill them all? So many questions but hopefully they will be answered in the upcoming episodes of the anime. We all have yet to find out.
