The Beast Titan (獣の巨人) is an unusual Titan that was first seen within Wall Rose during its supposed breach.

Appearance


The Beast Titan is an extremely unusual specimen, having a distinctly ape-like appearance. Its body structure and facial features are like that of a primate, though it walks upright like a human and stands at a previously unseen 17 meters in height. Dark fur covers the majority of its body, with the exception of its face, hands, feet, and torso. Its arms are also elongated, with long fingers and a fully-functional thumb. The proportions of its upper body are similar to that of the Colossal Titan, possessing a massive chest and small head, as well as unusually slim arms.

Personality
Calm and violently unpredictable, the Beast Titan seemed to have great knowledge and be very old. In its encounter with Mike Zacharius, it at first appeared to not notice him, but with a malevolent glance, plucked his horse from the ground and threw it at him with little effort. Its speech pattern was slow and thought out, and seemed to have a humorous yet malicious intent.

Clash of the Titans arc
The Beast Titan makes its first appearance when Titans are mysteriously appearing within Wall Rose even though the Wall remains intact. The Titan displays remarkable intelligence in its encounter with Mike Zacharius. It prevents his escape by killing his horse and ordering the other Titans not to eat him so that it can question him about the Three Dimensional Maneuver Gear. It takes Mike's gear for investigation when he neglects to respond.

It next appears walking past Castle Utgard, seemingly ignoring those taking refuge within. Instead, it uses its incredible strength to scale Wall Rose and disappears. Oddly, the reaction of Reiner and Bertolt to seeing it is later described by Ymir as resembling excited children.

As the soldiers manage to fend off an attack, it suddenly turns its attention towards them. It begins to break off chunks of the Wall, hurling it like missiles at members of the Survey Corps trapped in Castle Utgard. The first shot kills their horses, and the second kills Lynne and Henning. It then howls, summoning more Titans to continue the assault on the Castle. Nanaba angrily notes that it seems to be intentionally toying with them. Afterwards, it climbs over the Wall and disappears into the lost territory of Wall Maria.

The Beast Titan is said by Ymir to be directly responsible for the appearance of Titans within Wall Rose, possibly in order to "test" humanity's strength. She reveals that locating it was one of Reiner and Bertolt's primary goals and is key for them to return to their village.

In the aftermath of Eren's kidnapping by his former comrades, an investigation is performed at the village of Ragako. The investigation confirms the suspicion that the villagers had been transformed into Titans, though the methods employed by the Beast Titan remain unrevealed.

Abilities
Unlike other Titans, it is seen to be able to fully communicate with other Titans and give orders to them. It's also able to speak to humans, and is the only one to fluidly speak the human language. It possesses great physical strength, sufficient to break off large chunks from Wall Rose and hurl them a great distance away.

It is revealed to possess some unknown means to transform humans into Titans. These Titans, unlike regular Titans, were capable of functioning at night. As many houses showed signs of the transformations taking place indoors, it does not appear that immediate physical contact is required.
