The 4th and final season of the anime Attack on Titan (Shingeki no Kyojin) reveals the last important titans of the series, each giant possessing its own unique characteristics. Thus, all 9 titans have their own distinct traits.
Below you will find the nine titans revealed for those who don't follow the manga.
1. Original Titan
As the name suggests, the Founding Titan possesses the greatest strength of them all. Its power lies in tracing the famous 'Coordinates' that connect all the Titans and the people of Ymir. With its roar, it can control the Titans and also alter the memories and physical composition of its people. Furthermore, the Founding Titan can also erase the memories of the Eldians on Paradis Island.
2. Attack Titan
Finally, we arrive at the Attack Titan, translated as Shingeki no Kyojin in Japan. This Titan possesses monstrous strength and fighting abilities, and throughout both seasons, it seeks freedom for its people. As the series progresses, its wielder gains access to the memories of the ancient heirs, eventually being able to see both the past and the future.
3. Colossal Titan
He was the titan that opened the way for the series' storyline. The Colossal Titan is extremely gigantic, able to control the steam from its body to create defenses against being hit, and capable of burning its enemy alive.
4. Female Titan
With immense strength and a unique fighting style, the Female Titan can harden her body and use her scream to summon other Titans. She was responsible for the ending of the first season of the series.
5. Beast Titan
Being the strangest of the titans due to its ape-like appearance, the Beast Titan's main weapon is its ability to throw objects. Furthermore, it can control other titans, making them transform at its command, provided they have come into contact with its spinal fluid.
6. Jaw Titan
Therefore, he is the Titan whose wielder has changed the most throughout the series. His power comes from his jaws and claws, capable of destroying anything. Furthermore, his agility is always ahead of that of the other Titans.
7. Titan Cart
Essentially used as a weapons vehicle, the Titan Cart's quadrupedal form allows it to achieve above-average speed, serving to transport weapons and supplies in Titan wars.
8. Armored Titan
One of the main titans that served to drive the entire plot involving Marley and Paradis Island. The Armored Titan's body is composed of armor plating, which serves as protection against damage, also hardening certain parts of its body.
9. War Hammer Titan
This titan was the last to be introduced in the saga, belonging to the Tybur family for generations. The War Hammer Titan can crystallize parts of its body or other titans to create any deadly weapon in times of war.
Finally, the fourth and final season of Attack on Titan, at the time of this publication, is being shown in Japan with simultaneous streaming in Brazil on Crunchyroll.
