Jaw Titan

"The Jaw Titan is an assault unit. Its small size makes it the swiftest of all. Its powerful claws and jaws can crush just about anything."

- A Marleyan analysis of Marcel's Jaw Titan

The Jaw Titan (顎の巨人) is one of the Nine Titans with ferociously powerful jaws and nails. It is also known as the swiftest Titan of all thanks to its small size. It is currently in the possession of Porco Galliard.

Speed and agility
Those who hold the power of the Jaw Titan demonstrate significant amounts of speed and agility in their Titan form, they can even move fast enough to catch one of the Nine Titans off guard. Though the Jaw Titan is relatively small and weak, its mobility excels in terrain such as Titan Forests.

Crushing strength
The Jaw Titan also possesses, as its name implies, an incredible biting and crushing strength in its jaws and nails which can be used with devastating efficiency against both Titans and man-made structures. Its claws are strong enough to cause severe damage to armored opponents such as turrets and even the crystal shell created by the War Hammer Titan. The force of the jaw is shown to be strong enough to chew through the hardened Titan armor generated by Eren as well as the aforementioned crystal shell surrounding the War Hammer Titan, something, not even the Attack Titan was able to achieve.

History
The Jaw 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 Jaw 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 Jaw Titan was taken by the nation of Marley during the Great Titan War.

Around the year 843, Marcel Galliard was chosen to inherit the power of the Jaw Titan. He would later make use of his Titan form during a war between Marley and an enemy nation, using his Jaw Titan to destroy the enemy's artillery guns. In the year 845, the nation of Marley sent out Marcel, Reiner Braun, Bertolt Hoover, and Annie Leonhart across the ocean to the island of Paradis as the start of the Paradis Island Operation. However, at some point before the attack on Shiganshina District, a Titan approached Reiner and nearly had him in its grasp until Marcel moved him away to safety. Marcel was caught in Reiner's place, and he was eaten alive as his comrades escaped. The Titan inherited Marcel's Jaw power and regained its human form: an Eldian girl named Ymir, who had been wandering as a Titan for around sixty years. Choosing to start a new life for herself, Ymir made her way into humanity's territory and began living as a thief in the interior territories of the Walls. At this time, she overheard the story of "Krista Lenz" from members of the Church of the Walls and her plans to join the 104th Training Corps. Desiring to meet her for political and personal reasons, Ymir joined the Training Corps in the same year as Krista.

At some point during their training, Ymir and Krista faced difficulties escorting a sick trainee to shelter in harsh winter conditions. Wanting to see Krista survive, she sent her off to the shelter alone and used the Jaw Titan to bring their fellow trainee to safety at the base of a cliff side. Krista wondered at how Ymir could have possibly reached the shelter before her. Ymir agreed to tell her secret to Krista under the condition that when the secret of her Titan power was publicly known, Krista would go back to living under her true name.

Clash of the Titans arc
During the Wall Rose invasion in the year 850, Ymir is among the recruits of the Survey Corps when they are cornered by Titans at Utgard Castle. Seeing no hope for escape, Ymir chooses to make use of her Titan form to confront the Titans. Transforming before her friends' eyes, she battles the Titans at the base of the castle as the others comprehend the revelation of her powers. Reiner and Bertolt recognize her Titan as the one that ate Marcel five years ago and determine that they must capture her along with Eren when the time comes. When Ymir begins to struggle, Krista offers her encouragement. Ymir's Jaw Titan ascends the castle and saves the others from its collapse. When the dust settles, Ymir's fatigued Titan is unable to continue fighting against the Titans, but her life is saved by the arrival of the Survey Corps soldiers from the Stohess District raid. She is safely extracted from her Titan, and Krista reveals her true name as Historia Reiss. Shortly afterward, when Bertolt and Reiner reveal their identities as the Colossus and Armored Titans, Ymir is taken by the two Warriors along with Eren. After some questioning, Ymir agrees to cooperate with them in order to capture Historia. When the Survey Corps finds their location, she takes Historia into her Titan's mouth and escapes with Bertolt and the Armored Titan. Ymir remains within her Titan form throughout the escape, taking a moment early on to partially expose her human form in the nape in order to speak with Historia. Ymir abandons the Armored Titan when it is swarmed by a horde of Titans lured by Commander Erwin Smith and assists the Survey Corps for a short time, but upon seeing Eren's use of the Founding Titan during the battle Ymir chooses to go with Reiner and Bertolt rather than staying with the Eldians of the Walls. After the battle, Ymir escapes with Bertolt and the Armored Titan to the ruins of Shiganshina District.

Marley arc
During the two months afterward, Ymir is sent to Marley. At some point before or during the year 854, Porco Galliard, Marcel's brother, is chosen to inherit the power of the Jaw Titan from Ymir. At the climax of the Marley Mid-East War during the battle of Fort Slava, Galliard is present in the trenches dug by the Marley Warrior unit surrounding the fort. Cadet Colt Grice suggests making use of Galliard's Jaw Titan and Pieck's Cart Titan against the defenses of the Mid-East Allied Forces, but Commander Magath rejects the proposal due to the presence of anti-Titan artillery patrolling the perimeter of the fortress. However, once cadet Gabi Braun destroys the armored train carrying the artillery using explosives, Galliard is sent out onto the battlefield. His Titan proves to be more than enough to defend against the turret-fire from the bunkers surrounding Fort Slava, and Galliard's Titan makes quick work of Marley's enemies.

Galliard's attack on the Mid-East defenses is met with support from the 800-Warrior unit and Pieck's Cart Titan in full battle armor. Using the immense strength of his Titan's jaws, Galliard rips the railways from the ground, ensuring a complete immobilization of the Allies' defenses. Shortly afterward, Galliard retreats as Zeke Yeager begins a Titan airstrike directly above the fortress, dropping dozens of mindless Titans onto the Allies. When Reiner Braun joins the fight as the Armored Titan, Galliard assists him in destroying the remaining anti-Titan artillery stationed within the ruined fortress. Over a month later, the Jaw Titan returns during the Battle of Liberio when the Attack Titan makes a sudden appearance and begins a massacre. The Jaw Titan swings onto the Attack Titan's back, attempting to bite into the nape to take the Founding Titan, but its jaw muscles are sliced by Levi Ackerman before the nape could be bitten through. The Attack Titan throws Jaws into the nearby building, where the Survey Corps surrounds it in preparation for battle. The Cart and Beast Titans soon join the Jaw Titan in the plaza, and the Warriors prepare to battle the Eldians of Paradis. Observing the movements of the enemy's maneuvering equipment, the Jaw Titan leaps up from a building as an enemy soldier appears flying above the Cart Titan ready to launch a Thunder Spear, and slaughters the soldier mid-air. After the Attack Titan transforms once more, the Jaw Titan charges it, but is intercepted by Mikasa Ackerman, who the Jaw Titan then engages. After going after the Attack Titan, the Jaw Titan rakes the side of its face and inadvertently grazes the crystal surrounding the holder of the War Hammer Titan. After a quick flurry of strikes, it retreats back to the husk of the War Hammer Titan.

The Jaw Titan spots an incoming airship that serves as the method of escape for the Survey Corps. It then goes to bring it down but is caught off balance due to Mikasa slashing its legs and severing one of its feet. Crashing next to the Attack Titan, the Jaw Titan is further rendered helpless by getting both of its arms torn off. Then the crystal is jammed into its mouth and the Jaw Titan is unable to stop the Attack Titan from applying enough pressure to shatter the crystal, killing the holder of the War Hammer Titan. It then is targeted by the Attack Titan but is saved by the arrival of Reiner and his partially formed Armored Titan.
