The Raft

The Raft is a super-security prison at Ryker's Island Prison, with the objective to hold a vast amount of super-powered criminals, for example: Scarecrow, Controller, the U-Foes, Karl Lykos (Sauron), Crusader, Hydro-Man, Carnage (Cletus Kasady) and also contained the weak-minded Sentry. Electro once started a break-out to free Karl Lykos, which, unintentionally created the original New Avengers.

The Raft is perhaps the top super-powered criminals prison establishment of the U.S. Most escaped during Spiderman: Breakout but were recaptured. It was also a target for the Skrulls during Secret Invasion. Recently, it was destroyed by The Juggernaut after he became the seemingly mindless Kuurth, Breaker of Stone, releasing almost all of the inmates in process.
