Nidhoggr (ニーズヘッグ), also referred to as the Invincible Snake (不死身(ふじみ)(へび)), is a jaeger corps active in western Zemuria. They are stated to be a solid corp that never has trouble obtaining employment.


Nidhoggr's squads are named after human body parts in German, such as the Nase ('Nose') platoon operating in Nord Highlands during the Erebonian Civil War on behalf of the Noble Alliance or the Magen ('Stomach') battalion involved in the attempted assassination of Prince Albert von Bartholomeus during the Trilateral Summit in Crossbell on behalf of Count Jerome von Bartholomeus.

Former Nidhoggr squad leader Nacht Weiss says that Nidhoggr owes its invincibility and naming structure to the dissatisfaction in the world: every time one of Nidhoggr's squads get disconnected from the main body, such as an 'Arm' or a 'Leg', it is being regenerated by people upset with the society, criminals and other jaegers in the world.
