P. Eckstein is a Nazi Officer and a Major of the Gegengeist Gruppe. He worked closely with the Butcheress (though he did not seem to like her) and experimented with the toxic gas, using the natives as test-subjects. Eckstein tried to eliminate Rayne with the toxic gas, but Rayne kills him using his own trick; by kicking and breaking the protective glass to his room, allowing the gas to leak in. Shortly after, Rayne knocks on the door of the roof. The Butcheress sees Eckstein in the peephole, but as it turns out, Rayne severed Eckstein's head and held it up, so the Butcheress opens the door and Rayne attacks.
- P. Eckstein appears in Nocturne as a member of Domestic Super-natural Defense and Research League aka. "Spook-House" in 1902.
- One Paul Eckstein is credited as Quality Assurance Manager in BloodRayne, which might be the origin of this name.
