So I finally caught up with the Shingeki no Kyojin (Attack on Titan) manga. It was a long read but totally worth it. The manga release is only one chapter per month but is around 50 pages long. Anyways since I am bored, I compiled some information about the Titans, fans of the series might like.

What is a Titan?
Titans are a race of giant man-eating humanoids that serve as catalysts for the events in the series. The people inside the Walls are taught that they rapidly exterminated humanity to the point of near-extinction. In reality, they are transformed humans known as the Subjects of Ymir and have existed for nearly 2,000 years.

What is the Subjects of Ymir?
The Subjects of Ymir are an ethnic group descended from Ymir Fritz and the only race capable of becoming Titans.
Currently, Titans are classified into three types:
Pure Titans
Pure Titans is the most common form of Titan in Shingeki no Kyojin. They range from about 2-15m in height and have human features (only bigger and with some deformities). Their most common feature is their mindlessness and lack of self-thought. They mindlessly attack any humans nearby, making it easier for humans to predict their movements and defeat them.
Abnormal Titans
Pure Titans that show some abnormal and unpredictable behaviour are classified as Abnormal Titans. Unlike Pure Titans wherein it automatically attacks any humans nearby, the Abnormals sometimes ignores humans nearby and focus their attack unto something they deemed of interest. Titans with the ability to utter some words(mumbo-jumbo) are also classified as Abnormal Titans.
Nine Titans
The Nine Titans are the nine special titans that inherited the fragments of Ymir Fritz's(the First Titan) soul. The humans behind this Nine Titans have extraordinary regenerating abilities and the ability to transform into their titan form at will. Each of them have special abilities unique only to them.
If you haven't caught up with the manga and wants to avoid some potential major spoilers then you should probably stop reading from this point. XD
The Nine Titans are:
Founding Titan
The Founding Titan is the first of the Nine Titans, and the first of all Titans. It has the ability to create and control other Titans and even modify memories of Subjects of Ymir. The current holder of the Founding Titan is Eren Yeager.

The War Hammer Titan had been in the possession of the Tybur family for years until Eren ate Lady Tybur. The current holder of the War Hammer Titan is Eren Yeager. (Yeah!
