Lady Stilt-Man's origin still remains a mystery. She uses a version of the Stilt-Man's Suit. Deadpool defeated her by removing a manhole cover, causing one of her legs to fall in, and her other to step onto a high heel attached to the top of a truck. She doesn't appear to be connected to any of the other Stilt-Men. She is, however, clumsy and uncoordinated, and Spider-Man himself said that she was trying too hard. Spidey webbed her to the wall after her second heist.
Still attached to the legacy of the original Stilt-Man but discouraged by the mockery made of her alias, Callie decided to simply go by Stilt-Man. Around this time, she joined Misty Knight's Crew. She later defected to Purple Man's team Villains for Hire.
When the Shadow Council assembled their own version of the Masters of Evil, Lady Stilt-Man was recruited into the group. Later on, Stilt-Man appeared as a patron at the Croupier's criminal casino. She was swiftly taken out by Domino, and Daredevil. While operating with the Masters of Evil in Bagalia, Stilt-Man battled the Secret Avengers, who were trying to free Taskmaster.
After Daniel Gump, a precog who had sold his soul to these powers, became targeted by Deadpool. He hired a group of mercenaries, including Lady Stilt-Man, to protect him. Deadpool fought against Gump's protectors with Spider-Man (Otto Octavius). Deadpool blew up her legs, then captured her and the other criminals and killed Gump.
