As a scientist, inventor, and engineer, Wilbur Day was employed by Kaxton Laboratories owned by Carl Kaxton, who invented a hydraulic ram device. Wilbur stole Kaxton's designs and used them to engineer a pair of extremely long, telescopic metal legs, which allowed him to tower high over the ground. He incorporated these hydraulic stilts into armored battlesuit, which he created for use in robberies as the professional criminal Stilt-Man.
Turk Barrett later stole the Stilt-Man Suit. He offered his services to the Kingpin but was declined. The Kingpin contended that he did not employ "idiots". The original creator of the Stilt-Man armor, Wilbur Day, contacted Daredevil with knowledge of how to defeat Barrett.
Wilbur was one of many armored villains whose technology had been upgraded from stolen plans from Stark Industries. He was defeated by Iron Man when Tony threw one of his own hydraulic legs at him, knocking him out.
After Christine Cord was let out of jail, she decided to pay her debt in another way: by joining the newest incarnation of the New Warriors consisting of de-powered Mutants after M-Day. After being given a version of Stilt-Man's armor, she took up the codename Longstrike, and began training with the team which included her brother. However, on one of the team's first missions to stop the Zodiac, she got too cocky when fighting Cancer and was brutally killed in front of the rest of the team.
Lady Stilt-Man origin and identity still remain a mystery. She uses a version of the Stilt-Man 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.
