The Plastic Prison was a prison designed to incarcerate Magneto.
Stryker made several visits to Magneto's Plastic Prison, brainwashing and interrogating him in order to extract information regarding Cerebro.
Mystique seduced Mitchell Laurio, Magneto's prison guard, and injected him with iron particles. Magneto later extracted the iron out of the Laurio's body, which killed him. He then destroyed the Plastic Prison, using spherical projectiles he formed from the iron, and escaped.
