In one of the many plot lines currently running in the B.P.R.D. Universe, Nazi scientists have found the soul of Rasputin (Yes, that Rasputin: the mad monk of Russia, long thought dead) embedded in a crystalline structure on the floor of a deep lake, and have managed to extract that soul and infuse it into the body of a giant. This is the frightening result of their project.
From B.P.R.D. Hell on Earth: The Return of the Master #4, the comic book with story credit shared by Mike Mignola and John Arcudi, art by Tyler Crook, and recently published by Dark Horse Comics.
