The Jaw Titan is the smallest of the Nine Titans at just 5 meters, but it makes up for its size with blinding speed and devastating biting power. Its jaws and claws can crush and tear through almost any material, including Titan hardening and armor. The Jaw Titan has had multiple holders from both Marley and Paradis, each using its speed differently in combat. Falco Grice's Jaw Titan developed the ability to fly after consuming Zeke's Beast Titan spinal fluid.
The Jaw Titan has a lean, compact body covered in light brown or gray muscle tissue, built for speed rather than raw power. Its most distinctive feature is the massive lower jaw that extends forward with large, sharp teeth designed to bite through hardened Titan armor. The face is somewhat like a dinosaur or reptile, with a pronounced underbite and small glowing eyes set far back on the skull. Long curved claws extend from its fingers and toes, functioning as deadly slashing weapons during hit-and-run attacks. Its tail is short and its legs are powerfully built for explosive acceleration.
The Jaw Titan possesses the strongest bite force of all Titans, capable of shattering the Armored Titan's hardened plating and the War Hammer Titan's crystal. Its incredible speed and agility make it extremely difficult to catch or hit in combat, allowing it to overwhelm larger opponents. The sharp claws can slice through Titan flesh and even the hardest defensive structures with ease. Falco Grice's Jaw Titan gained feather-like appendages after receiving Beast Titan spinal fluid, allowing it to fly through the air for the first time in history. Its small size makes it ideal for reconnaissance and surprise attacks behind enemy lines.
Marcel Galliard was the original Jaw Titan warrior from Marley who sacrificed himself to save Reiner from Ymir's Pure Titan. Ymir held the Jaw Titan for decades as a mindless Titan before regaining her human form, then returned it to Marcel's brother Porco Galliard. Porco used it against the Paradis forces before Falco Grice inherited it and developed the unique flying variant during the final battle.
