Wilhelm Strasse
Oberst Wilhelm StrasseObergruppenfuhrer (Lieutenant General) Wilhelm Strasse or Deathshead is head of the SS Special Projects Division as well as a senior member of the SS Paranormal Division.
A gifted researcher, Strasse's brainchild is the Ubersoldaten project, which sought to produce the ultimate soldier using cybernetics and bioengineering. His first attempts were the Lopers but they became self-aware and killed any human they saw. Not discouraged, Deathshead created the Super Soldiers, towering cyborg soldiers that were heavily armed and armored. He posted the prototypes in certain areas of the X-Labs and at the dig site near Castle Wolfenstein. Deathshead's non-prototypes were made Heinrich's Death Knights by the sorceress Blavatsky.
Unlike most members, Deathshead does not believe in the occult and prefers to arm the Nazi war machine using advanced technology. Heinrich Himmler asks him to join the resurrection ceremony for Heinrich I but Strasse declines to attend due to his disbelief in the occult. After the protagonist destroys one of his Ubersoldat warriors, he escapes in a rocket plane and goes into hiding, never to be seen again for the rest of the game. Strasse earned his nickname from his skull-like visage, which has a scar running across it. (The nickname also may be a reference to the 3rd SS Division Totenkopf symbol used by Himmler). Strasse also shows a grudging respect to Blazkowicz after he successfully defeated the Ubersoldat, this is shown in a letter to Himmler that warns Himmler not underestimate the American agent.

Helga Von Bulow
Oberfuhrer (Senior Colonel) Helga Von Bulow is a high ranking officer within the SS Paranormal Division and also founder of the order of the Eliteguards, the SS Paranormal Division's all-female security force. She is Blavatsky's pupil and is a firm believer in the occult. Although a capable leader, Helga tries too hard and makes rash decisions that jeopardize the safety of her troops. While the Elite Guards are loyal to her, the male soldiers under her command are skeptical of her choices. Helga and her colleague, Professor Zemph, located the Dagger of Warding in a mausoleum next to the Wulfburg Church. Helga eagerly desired it while Zemph warned her that taking it will unleash a dangerous evil on the world. Her mind made up Helga shoots Zemph, takes the dagger, and is immediately dismembered by the fearsome Olaric.

Olaric
The Olaric was a monster that inhabited the Wulfburg Church. It was large and bipedal and was covered from head to toe with the faces of tormented souls. The Olaric was released from limbo after Helga Von Bulow took the Dagger of Warding and its first act was to kill the Nazi commander. Before it could do anything else, the Olaric faced Blazkowicz and either attacked with its fists or by unleashing a deadly spirit attack. Ultimately, the Olaric was destroyed by the American.

Heinrich I
Heinrich I was an evil warlord who launched a campaign of conquest in Medieval Europe. He had studied the black arts and used them to his advantage. A noble wizard confronted Heinrich and imprisoned the tyrant in limbo. After many years, Heinrich was revived from his stasis by the sorceress Blavatsky who worshiped him as her master. As a reward, Heinrich turned her into a zombie slave. The protagonist, B.J. Blazkowicz, faced Heinrich in a fierce duel of sorcery and guns and defeated him once and for all.

Heinrich Himmler
The only non-fiction character of this game, various sources claim that Himmler was interested in the occult and a vision of the "supersoldier" and that he was one of the figureheads for Nazi occultism. In the game, he appeared in a short cameo in the last cutscene, watching BJ defeat and kill Heinrich I from a good distance. He expressed bitterness at the Ranger's victory and somberly walked away to give a report to Adolf Hitler.
