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

Human Form
In his human form the Beast is has a well toned body with no shirt, loose pants, and combat boots. He wears circular glasses with shaggy blonde hair and a matching moustache that transcends down into his beard.

Titan Form
In his Titan form, he is an extremely unusual specimen, having a distinct, ape-like appearance, his Titan's body structure and facial features are like that of a human's, he walks upright like one also. He stands at a previously unseen 17 meters in height. Dark fur covers the large majority of his body, with the exception of his face, hands, feet, and torso. His arms are also elongated, with long fingers and fully-functional thumbs. The proportions of his upper body are similar to that of the Colossal Titan, possessing a massive chest and small head, as well as unusually slim arms.

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. It is encountered by Mike Zacharius, who instantly notes the strangeness of its characteristics. The Titan then displays an unexpected behavior when it grabs Mike's horse and launches it to him, preventing his escape and throwing him from the roof he was on.

After Mike falls to the mouth of a Titan, the Beast Titan demonstrates the ability to talk, ordering the other Titan to not eat him so that it can question him about the 3D Maneuver Gear. However, the Titan disobeys it and the Beast Titan crushes its head to release Mike.

The Beast Titan then proceeds to interrogate Mike, but since he neglects to respond, it theorizes that he does not speak due to them not speaking the same language, or Mike being too afraid. After inspecting the gear, it allows the surrounding Titans to devour Mike. As Mike screams in horror, the Beast Titan is amused to see that they did speak the same language after all.

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.

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 long distance 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.

When Ymir and Eren are kidnapped by Reiner and Bertolt, Ymir states that the Beast Titan is directly responsible for the appearance of Titans within Wall Rose; possibly in order to "test" humanity's strength. She also notes that the reaction of Reiner and Bertolt to its appearance resembled gawking, excited children. She theorizes that locating it must be one of their primary goals and is key for them to return to their village.

In the aftermath of Eren's failed kidnapping, 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 undisclosed.

Two months after Historia Reiss is crowned queen, the Beast Titan is shown in Shiganshina District defeating the Armored Titan. He then emerges from his Titan body and reveals his plan to ambush the Survey Corps there with the help of Reiner Braun and Bertolt Hoover in order to capture Eren and steal the Coordinate, revealing it as their top priority.

Abilities
Unlike other Titan Shifters, he is able to fluently speak without issue in his Titan form, casually talking to other Titans and even giving them orders. He possesses great physical strength, sufficient enough to pick up a horse or even break off large chunks from Wall Rose and hurl them at a great distance away. It also seems very skillful because it managed to retrieve Mike's Three Dimensional Maneuver Gear without damaging him or the gear.

It is revealed to possess some unknown means to transform humans into Titans. These Titans, unlike the regular Titans encountered, 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 to cause a transformation.

He has never seen fighting but the fact that he won a fight against the Armored Titan signals that he is very strong.
