- "There it is, the island–Three Mile Island; hiddin' in plain sight. No one's gonna snoop around a nuclear reactor. They think it's gonna turn 'em into freaks."
Three Mile Island is a nuclear power plant located in the Susquehanna River, south of Harrisburg, Pennsylvania.
During the 1970s, it served as a mutant prison run by William Stryker and his team of scientists, where they experimented on and combined the mutants' powers for the Weapon X and Weapon XI programs. The facility was destroyed in 1979 following a battle between Wolverine, Sabretooth and Deadpool.
