Much like everyone else, I'm sadly forced to point out that the concept of Nazis fucking with stuff that no man should isn't just relegated to Hellboy. Also, to say Hellboy is just like this is to give Hellboy a very, very short sell.

That said, I can see where the direct parallels come into play, especially in these pages and the first HB movie. A Nazi project left alone for decades, about to be reactivated, with strong elements of the occult, and a mention of the Thule Society? It does seem like direct lifting, almost.
