The War Hammer Titan was one of the Nine Titans, capable of creating weapons and structures from hardened flesh. Its abilities allowed the formation of spikes, blades, and its signature hammer, even operating remotely with the user encased in a crystal. This crystal could only be broken by the Jaw Titan’s claws and teeth. While powerful, its usage quickly drained stamina. The last known inheritor was Lara Tybur, before it was taken by Eren Yeager. 

The War Hammer Titan could produce and manipulate structures made of hardened Titan flesh. These structures could be weaponized, such as pikes large enough to impale a 15m Titan, spikes flooding areas, and its signature war hammer. It could also create bladed weapons like a sickle, battle axe, or broadsword, and even flexible components such as crossbow strings or whip-like weapons.

Like the Female Titan, this ability could encase the operator in a crystal casing, but unlike her, the human remained conscious and in control. The casing was durable but could be broken by the Jaw Titan’s claws and teeth. However, overuse of this power could quickly drain stamina, as noted by Theo Magath. 

Unlike the other Nine Titans, the War Hammer Titan could remove its control center from the nape. Instead, the Titan body was connected to its human operator by a cable of flesh, while the operator was encased in crystal. If the cable was severed, the Titan body was deactivated, though a new one could still be created. Additionally, the War Hammer Titan could emerge from different locations upon transformation since the operator did not need to be in the nape.
