As Metropolis is often intended to mirror New York City, so too does Stryker's Island become analogous for the real-world prison facility, Riker's Island. However, the two do exist as separate institutions, as Riker's Island exists within the DC Universe as well.
Stryker's Island is a maximum security federal prison that serves the city of Metropolis. It is located on an island in the West River between New Troy and Queensland Park. In addition to housing some of the worst offenders that Superman has fought, it is also designed to contain various super-powered individuals as well which includes criminals like Bloodsport I and II, Metallo, Kryptonite Man (K. Russell Abernathy), Lex Luthor, Parasite, and Shrapnel. Daily tours of the facility are provided to help supplement the rising costs of staff, maintenance and upkeep.
