Rudi Jäger

Rudi Jäger is an SS Major serving as the prison warden of Castle Wolfenstein and a major antagonist in Wolfenstein: The Old Blood.

History
Rudi Jäger oversaw a cable car checkpoint along with his dog Greta. As Blazkowicz hands over his forged ID papers during his attempt to get past the checkpoint, Rudi grabbed B.J.'s hand and examined the passport. He then asked B.J. if he's a Frankfurter, to which B.J. replies to Rudi by saying he's a "hot dog". This causes Rudi and the guard manning the checkpoint to laugh and they then let B.J. go through.

Rudi later appears accompanied by a Super Soldier to confront B.J. and Agent One. The Super Soldier knocks B.J. out with a single punch, and Jäger has him and Agent One taken to the dungeons.

Later, when B.J. escapes and attempts to rescue Agent One, Rudi knocks B.J. out from behind as he is attempting to free him and has him placed in the electric chair he was using for interrogation. When B.J. wakes up he finds Greta eating Agent One's corpse and Rudi standing before him. Rudi attempts to interrogate B.J., but B.J. manages to break free while being electrocuted. He then throws Rudi into the chair and electrocutes him with it. Greta attacks then B.J. and B.J. manages to kill it, but this distraction provides a chance for Rudi to escape.

As B.J. fights off Nazis alongside Annette and Kessler in Paderborn, Rudi appears again in a suit of power armor and begins firing at B.J., yelling furiously at him for killing Greta. However, B.J. manages to disable the armor and make Rudi vulnerable before killing him with two stabs to the head.
