Thunder Spear (Anime)

The Thunder Spears (雷槍) are a technology specifically developed to fight against the Armored Titan. Referred to as "iron rods" by Eren Yeager, their official name is Thunder Spears, due to their spear-like shape and the thunderous sound they make when used.

Return to Shiganshina arc
Hange Zoë has the Corps of Engineers develop the Thunder Spears, using technology uncovered following the coup d'état. Designed as a weapon to combat the Armored Titan, Hange displays the performance of the spear to Scout Regiment soldiers.

In the battle in Shiganshina District, the members of Fourth Squad and the Special Operations Squad surround the Armored Titan in its battle, barraging it with explosives and blowing through its armor to detonate its nape.
