While brooding in his study over how to be a more effective crime fighter, Bruce Wayne saw a bat come through his window (in the earliest Detective Comics portrayal simply flying in an open window, in Post-Crisis continuity such as Batman: Year One, dramatically crashing through the glass) and perch on the bust of his father. Realizing that "criminals are a superstitious, cowardly lot," Bruce adopts the persona of a bat in order to conceal his identity and strike fear into his adversaries. Subsequent origin tales have had Bruce terrified by bats as a child, and observing a bat costume worn by his father at a costume ball, but the primary impetus of his decision to adopt the bat persona has always been the incident of the bat coming in the window of his study. It is as a result of this incident that the batsuit was developed.

While in an ESU laboratory, Peter invented a white & blue suit that was made of steel plates that were from a pseudo-metallic composition using a modified webbing formula. He used this costume during the "My enemy's enemy" story where he fought Blood Rose, Gauntlet and the heavily armed New Enforcers. The costume was destroyed by acid during the battle and was never rebuilt. Despite providing Spider-Man with increased durability and strength, it slowed down his movements.

Her key role of deciding between crime and having complicated relationships of Spider-Man makes her sometimes labeled as part with the rest of the major rogues gallery of Spider-Man.
