Also known as: アルトアイゼン
A development of the Gespenst, the Alteisen is a heavy, close combat mecha, so heavy in fact it needs its own anti-gravity system in order to remain upright. It possesses the revolver stake Pile Bunker, a multi-missile system and area denial shotgun in its shoulders, a heat horn on its head, and a three-barreled autocannon on its left arm.
It is piloted by Kyousuke Nanbu.
The mech is later upgraded to Alteisen Riese.
