Parahuman Retention Center

The Parahuman Retention Center, code-named "Alcatraz II", is a maximum security prison built to house Parahumans in the 1950s during The Parahuman War in San Francisco, California. All inmates are forced to wear Anti-Power Bracelets, which were created from the aura of a Parahuman with power nullification by The Repoman. The facility houses around five hundred of the world's worst powered criminals, though it can house another two hundred or so.

After the breakout in 1997, the following security measures have been put in place:
 * All inmates are subjected to permanent solitary confinement
 * Visitors are not allowed under any circumstance
 * The PIU has an elite squad of twelve on-site
 * The building has been relocated to an undisclosed location
