A monstrous "mobiletank" built by Zeon with the intent of busting fortresses and defeating land battleships while retaining excellent speed.
It could partially transform into "Mobile Mode" - when in this form, its torso would raise from the chassis, revealing two manipulators capable of wielding weapons and being able to pivot its huge main gun - however, said gun was so powerful, firing it while the Hildolfr was not held in place by braces risked tipping the machine over with every shot due to the massive recoil.
