Leather is a comic book character and a partner in crime of Lace. She's first and only appear in Web of Spider-Man Super Special.
Nothing is known about Leather and Lace except that they are "independent operators climbing up the underworld ladder" and have presumably committed several successful crimes. When the Black Cat learns that the two women plan to rob Mikkal's, a Manhattan restaurant, she first offers her security services to the manager and then, when rejected, decides to allow Leather and Lace to complete their robbery so she can recover their haul and embarrass Mikkal. The Cat watches the two criminals climb to the restaurant, but when she sees that her former boyfriend Flash Thompson is at Mikkal's with a date, she decides to prevent the robbery. After a brief skirmish, she binds them both in her cable, and all three crash into Mikkal's office, where the Cat demands a fee for her services; Flash and his date never realize that there was any danger, and the unconscious Leather and Lace are presumably arrested and jailed.
Leather possesses a high, possibly superhuman level of strength and endurance; she has steel claws on her gloves which are strong enough to pierce concrete and which she can use for both fighting and climbing. Lace can fly and emit blinding light from her body.
