While their boyfriends were the superheroes in their relationship, there were brief periods when both Lois Lanes gained their suitors superpowers. On Earth-One, it was on the occasion when Clark finally had enough of Lois' snoopy and suspicious nature over his dual identity and transferred his powers to her on a short-term basis. Of course, the goal was to see how she would conceal her change of identity when trouble manifested itself. Which she accomplished until they very end, as plain Ms. Lane, ace reporter. There would be other opportunities where Lois would gain superhuman abilities, such as when she borrowed her frenemy Lana Lang's bio-ring to replicate the redhead's superheroine alias of Insect Queen during one misadventure. Mostly, though, it was Lois' own tenacity towards getting to the truth her fearlessness were her most endearing aspects in Kal-El's eyes.
The Lois Lane of Earth-Two had finally figured out about her Superman's dual identity, after marrying him! As Mrs. Kent, she was surprised to see with her there-to-fore unknown ability of x-ray vision an alien plant her husband was hiding in a closet for their anniversary. Said plant transferred his abilities to her, and the couple realized that they would need to work together to continue protecting Metropolis. Working behind the scenes, she helped him simulate all his former abilities through her unseen actions. And then, her powers were also gone. Although Lois would continue to aid her mate on his various cases for the years and decades to come, using her own self-sacrificing and intuitive nature to help the Man of Steel continue to protect the city the both loved, while continuing her stellar career as the Daily Star's ace reporter. And the love of Kal-L's long and illustrious life, of course.
