Valerie from the Spidey Super Stories #6 (circa March 1974) was created by Jean Thomas, Winslow Mortimer, Mike Esposito and Tony Mortellaro based on the Electric Company script by Sara Compton.
Costume Trivia: Valerie found a Spider-man costume and customized it to mimic the real Spider-man’s power. She used suction cups on the fingers and feet of the costume to mimic his wall crawling abilities.
Valerie works at a library where she met Spider-man. In the library she had to deal with the Bookworm [Spidey Super Stories #6, March 1975] then the Vanisher [Spidey Super Stories #7, April 1975]. While working at the library she was attacked by ‘the April fool” whom she managed to thwart with her quick thinking right as Spider-Man arrived [Spidey Super Stories #10, July 1975].
She witnesses Spider-man save a jewelry store from the Vulture. Then she has the Spider-man costume fall in her lap while thinking about how cool Spider-man was. After getting the suit, she customizes it to compensate for the fact she has no natural spider powers. Spider-man met her in costume as she crawled up a wall and he allowed her to continue operating as the other “Spider-person”. She later helps Spider-man battle and defeat The Vulture and turn him over to the police in Spidey Super Stories #11, August 1975.
