King Otto I's monster

King Otto I's monster is the final boss of Wolfenstein: The Old Blood.

History
The monster was originally created by King Otto I's alchemists and was one of many in his army. However, upon witnessing the destruction caused by the monster, Otto I declared it an abomination and trapped it in a tomb under Castle Wolfenstein before burning Wulfburg to the ground.

In 1946, the monster was excavated by an SS Paranormal Division force led by Helga von Schabbs that blew open the tomb, causing the gas emitted by the monster revive all the surrounding dead as zombies. Though seeming tame at first, the monster soon killed both Helga and Emmerich Schreiner before being defeated by B.J. Blascowitz.
