The Amazing Spider-Man #215

In "By My Powers Shall I be Vanquished!", Spider-Man finds himself reluctantly teamed with Namor as the Frightful Four set a deadly trap, forcing the heroes into a desperate retreat. With Namor returning to Atlantis and Peter Parker chasing clues about a mysterious woman he’s been seeing, his search leads him straight into the clutches of Llyra of Atlantis—a stunning figure with secrets of her own. Written by Denny O'Neil and illustrated by John Romita Jr. and Jim Mooney, with colors by Roger Slifer and letters by Jim Novak, the cover by John Romita Jr. and Al Milgrom captures the tension of this high-stakes encounter.
