Das Ungerhauer — literally 'the Monster' — is the most immediate physical threat faced by H-Cell. Standing over seven feet tall, he moves with an uncanny aquatic grace, his skin iridescent, his joints unnaturally flexible, and his flat black eyes utterly expressionless. He bears what operatives have come to call the Innsmouth look, suggesting Deep One heritage or corruption. He serves Karl von Drexler of the Karotechia cell known as the Scions of the Black Sun, and Brandt's journal reveals she both feared and coveted control of him.
Das Ungerhauer's combat encounter at the Oasis of Whispers proved catastrophic for the joint H-Cell and Hedgehog operation. He absorbed critical hits from multiple firearms — including a heavy machine gun round that visibly hurt him for the first time — and regenerated his wounds between exchanges. Private Harris was killed instantly when Das Ungerhauer punched his head clean from his shoulders, causing mass temporary insanity among the soldiers present. Only concentrated fire from Haze's submachine gun and Taffy's heavy machine gun eventually brought him to the ground, but even then he was not confirmed dead.
