It stands at a previously unseen in height. Dark fur covers the large majority of its body, with the exception of its face, hands, feet, and torso.

The proportions of Its upper body are similar to those of the Colossal Titan, possessing a massive chest and small head, as well as disproportionately long arms.

Clash of the Titans arc
When Titans mysteriously appear within Wall Rose the Beast Titan is among them and is encountered by Miche Zacharius, who instantly notes the strangeness of its characteristics, mistaking the Titan with a regular Abnormal. As Miche's horse races back to him the Beast Titan unexpectedly grabs it. After noticing Miche the Beast Titan launches it at him preventing his escape and throwing him from the roof he was on. After Miche falls to the mouth of a Titan, the Beast Titan orders the other Titans to withhold on eating him so that it can question Miche about the omni-directional mobility gear. However, a Titan disobeys the Beast and it crushes its head to release Miche. The Beast Titan then proceeds to interrogate Miche, but as he neglects to respond out of shock, it theorizes that they do in fact speak the same language, but Miche is simply too frightened. After stealing the equipment, it allows the surrounding Titans to devour Miche. Miche screams in horror and pain while the Beast Titan is amused to see that he could in fact talk. It then leaves the grounds contemplating the ODM gear. The Beast Titan is later seen again wandering around outside Utgard Castle where several members of the Scout Regiment are trapped by Titans, despite Titans usually being inactive at night. It then climbs up Wall Rose and watches the Titans surrounding the tower from a distance. After the scouts kill most of the larger Titans, the Beast Titan begins throwing large stones at the tower, killing Lynne and Henning along with their remaining horses. Shortly afterwards, twice as many Titans begin to advance while the Beast Titan roars at them from atop Wall Rose. Nanaba notices the unusually strategic method in their attacks, indicating that the Beast Titan is controlling the other Titans actions. As the Titans swarm Utgard, the Beast Titan descends the other side of Wall Rose.
