Mac Porter is the founder and CEO of Damage Control a construction company contracted by S.H.I.E.L.D. to help in the clean up and repair after a super-villain attack on New York City.
Following a fight with the Wrecking Crew, Spider-Man and the other S.H.I.E.L.D. Trainees are ordered by Nick Fury to work with Damage Control in order to find out the Wrecking Crew's motives. While working on Damage Control, Spider-Man finds out that the clean-up work has been used for a covert bank robbery, and he begins to suspect Mac Porter.
Later that night, Spider-Man infiltrates the Damage Control building to investigate Mac Porter, but discovers instead that four of the Damage Control workers are actually the Wrecking Crew in disguise using their Damage Control membership and equipment for robberies. Mac Porter arrives to help Spider-Man's team and the Wrecking Crew is defeated.
