The Beast Titan is a mysterious Titan capable of speech. It is first seen during the invasion of Wall Rose.
|The Beast Titan is the same as ever. It's a bit larger than the others, but that's far from all. Its pitching assault is an unprecedented, awe-inspiring weapon.|
|— A Marleyan analysis of Zeke's Beast Titan|
On its own, the Beast Titan is noted as being slightly larger than most of the other Nine Titans. It possesses a devastating ability to throw objects with great accuracy. This is notably used by Zeke Yeager's Beast Titan during the battle of Shiganshina District to wipe out most of the Survey Corps with crushed rocks and at the Battle of Fort Slava, where it performed the role of heavy artillery, launching missiles and wiping out the entire Mid-East Allied Forces fleet.
The Beast Titan is able to harden its body at will to protect itself from attacks. During his brief battle with Levi, Zeke Yeager tries to harden the nape of the Beast Titan to protect himself. However, this ability needs some time to prepare, as Levi is able to attack Zeke before he can harden his Titan.
Zeke Yeager's abilities
With his royal blood, one of the most perilous attributes of Zeke's Beast Titan is the ability to turn Subjects of Ymir into Titans. If a person is given Zeke's spinal fluid he is able to transform them with a roar, much like the scream-based abilities of the Founding Titan and the Female Titan. This ability can be used to devastating effect on the unsuspecting, such as the initiation of the Wall Rose invasion after the residents of Ragako were turned into Titans with the Beast Titan's power, and when the Marleyan military made use of this power to drop Titans onto Fort Slava in an airstrike.
Zeke's Beast Titan is able to exercise some control over Pure Titans through a scream-based ability. Using vocal commands, the Beast Titan is able to direct the actions of Pure Titans and can command them to move, resist the urge to eat humans, and stay in place. Titans under Zeke's control are even able to function using only moonlight without falling into fatigue. However, this ability is evidently imperfect; some Titans like the Gluttonous Titan can somewhat ignore Zeke's Beast Titan's orders.
The Beast Titan, like all the Nine Titans, was brought into the world after the death of Ymir Fritz. In the 1,700 years following her death, the Beast Titan was held in the possession of one or several of the warring Eldian houses subservient to the Founding Titan. After these seventeen centuries when Karl Fritz, the 145th King of the Fritz family, abandoned the conflicts of Eldia and relocated to Paradis, the Beast Titan was taken by the nation of Marley during the Great Titan War.
In the year 842, Zeke Yeager was chosen to inherit the power of the Beast Titan. Additionally, he was granted the title of warchief over all the Warriors of Marley. Over a year later, after the other Warriors had inherited their Titans, Zeke made use of his Titan form in a war between Marley and an enemy nation, using his Beast Titan to slaughter retreating soldiers in the battle.
In the year 850, Zeke Yeager infiltrates Wall Rose and uses the power of his Beast Titan to transform the residents of Ragako into Titans, possibly as a way to test the strength of the Eldians within the Walls. Shortly afterward, a small group of his Titans is spotted by Squad Leader Mike Zacharias, who begins a mission with fellow soldiers and recruits of the Survey Corps in spreading the news of a Wall Rose invasion. After killing five of Zeke's Ragako Titans, Zeke takes Mike's horse and throws it his way, sending him falling into the mouth of a gluttonous Titan. Zeke's Beast Titan stops the remaining Titans from attacking while he asks Mike about the weapon the Eldians are using against the Titans, but Mike is too afraid to speak. With no useful responses, the Beast Titan takes Mike's maneuvering equipment and leaves the scene, releasing his hold over the Titans and allowing for them to eat Mike alive.
Later that night, the Beast Titan climbs Wall Rose, tearing pieces of the Wall off to use as projectiles against a team of Survey Corps soldiers resting at Utgard Castle. He then leaves Wall Rose, not to be seen again for some time.
Presumably two months following Zeke's invasion of Wall Rose, Zeke meets with his Warrior subordinates Reiner Braun and Bertolt Hoover in the ruins of Shiganshina District. The two want to return into the Walls to rescue their comrade Annie Leonhart, though Zeke believes their best course of action is to wait for the Survey Corps to arrive in Shiganshina in order for the Warriors to obtain the sought-after "Coordinate." Conflict arises between Zeke and the two Warriors, who then decide their course of action through combat between Zeke's Beast Titan and Reiner's Armored Titan. The Beast Titan brutally overpowers the Armored Titan, and the decision is made to remain in Shiganshina.
When the Survey Corps arrive in Shiganshina District as Zeke had predicted, the Beast Titan acts as the commander of the Titan forces throughout the battle. As the majority of the Survey Corps is within the district, Zeke uses the power of his Titan to summon a blockade of Titans to the north of the district, preventing any escape. At this time, Zeke also collapses the northern breach of the city, cutting off the troops from their horses north of Wall Maria. Afterward, Zeke commands the smaller Titans under his influence to attack the soldiers north of the Wall. The Survey Corps battle with the smaller Titans for a short time, and upon hearing the warning call from Reiner's Armored Titan within the district, Zeke's Beast Titan hurls Bertolt Hoover into the city in a barrel that had been waiting on standby atop fellow Warrior Pieck's Titan, the Cart Titan.
After a brief delay, Bertolt transforms into his Colossus Titan, and in the meantime Zeke begins a new assault on the Survey Corps soldiers north of the district, using crushed boulders as projectiles and sending them at devastating speeds into the houses and structures to the north of Wall Maria. This strategy leaves the troops north of the Wall completely immobile, and Commander Erwin Smith joins them to formulate a do-or-die strategy against the Beast Titan. In a last resort, the Survey Corps charges for the Beast Titan using signal flares in an attempt to hinder its vision while Captain Levi maneuvers his way towards the Beast Titan, using the blockade of Titans as a path towards it. The Beast Titan's bombardment nonetheless completely eradicates the charging soldiers, killing Commander Erwin, and all but one of the recruits. However, in Zeke's distraction, Levi successfully ambushes the Beast Titan, completely dismembering it with no time for Zeke to plan a defense. Zeke emerges from his ruined Beast Titan at Levi's mercy, but is soon afterward rescued by Pieck. Zeke's injuries leave him unable to use his Beast Titan for the remainder of the battle.
Four years later, Zeke uses the power of his Beast Titan to transform a group of parachuting Eldian captives into Titans during the battle of Fort Slava at the climax of the Marley Mid-East War, creating a devastating airstrike. Once Reiner joins the combat on the ground and destroys the anti-Titan artillery posing a threat to Zeke's Titan, he transforms into the Beast and uses leftover artillery rounds as projectiles against the navy of the Mid-East Allied Forces stationed in the bay near to the fort. The fleet fires upon the Beast Titan before it is destroyed, but Reiner's Armored Titan saves Zeke from fatal injuries.
During the Survey Corps assault on Liberio a month later, the Beast Titan approaches the plaza where a showdown between the Corps and Marley's Titans is in effect. When next to Galliard and Pieck, he gives the order to wipe out the enemy. In the ensuing battle, the Beast Titan provides the Warriors with artillery support, hurling crushed debris around the plaza. Throughout the conflict, the Cart Titan protects Zeke from the Survey Corps, in particular Levi, and is in turn defended by the Jaw Titan. After the transformation of the Colossus Titan in the harbor, the Warriors formation is disrupted. While Pieck is distracted by the Survey Corps approaching attack, Levi ambushes the Beast Titan and swiftly cuts open its nape. Falling to the ground, Levi detonates an explosive in the Titan's neck before rapidly maneuvering away.
While much of the Marleyan military assumes Zeke to be dead, Gabi sneaks aboard the Survey Corps airship to seek revenge for her many fallen comrades; followed by a concerned Falco. After killing Sasha with a shot to the chest, they are captured and brought to another room which contains a limbless but still alive Zeke, still in possession of the Beast Titan. Hange reveals that Zeke and the Survey Corps are working together, and the airship moves out toward Paradis.
