The War Hammer Titan stands at 15 meters and has the unique ability to create weapons, structures, and projectiles from hardened Titan flesh. It belongs to the Tybur family, who ruled Marley from behind the scenes and kept the Titan's power within their bloodline for generations. The user can fight from a distance by encasing their human body in a protective crystal and controlling the Titan via a flesh tether. Eren Yeager consumed the War Hammer Titan during the Paradis invasion of Marley and added its powers to his arsenal.
The War Hammer Titan has a sleek, elegant appearance with a white, porcelain-like surface covering parts of its body, resembling ancient Marleyan armor. Its face is featureless with a smooth mask-like covering, no visible mouth or nose, and a single glowing crack across the forehead area. The body is slender and tall with long arms ending in sharp, claw-like fingers that can morph into weapons instantly. A thin fleshy cord connects the Titan's body to the user's crystal-encased human form, which is typically hidden underground or in a separate location for safety.
The War Hammer Titan can instantly create any weapon or tool from hardened Titan flesh, from massive spikes and spears to crossbows, whips, and even a giant war hammer for close combat. The user can operate the Titan remotely from a distance while their human body remains encased in an unbreakable crystal, providing near-perfect protection. The Titan can create structures such as shields, defensive walls, and even explosive projectiles that detonate on impact with devastating force. It can generate tendrils from the ground over a wide area, creating a web of deadly spikes to trap and impale enemies. The flesh tether connecting the user to the Titan is both a strength and a weakness — if severed, the Titan body becomes uncontrollable.
The Tybur family held the War Hammer Titan for generations, using it as a symbol of their power and influence over Marley's government. Lara Tybur was the last of the Tybur line to inherit it, wielding it in the Declaration of War against Paradis. Eren Yeager consumed Lara during the battle and gained the War Hammer's abilities, combining them with his Attack and Founding Titans for his final campaign against the world.
