b) The character Sersi, one of the Eternals, would be connected with Circe, an enchanteress who was able by means of drugs and incantations to change humans into wolves, lions, and swine, and can be read about in Homer's Odyssey, encountered living on the island of Aeaea

c) HR Giger's work suggests that he had been following Jack Kirby's work. When he came to design a Facehugger for Dan O'Bannon in 1977, I think he found inspiration in this panel with the gun barrell turning into fingers and so I think that he developed this into an early face hugger creature with long figures wrapping around the victim's face which would be carried over into the final design.
Perhaps the idea of magic being used to turn a gun turning into threatening organic tentacles was something in tune with Giger's biomechanics concept.
