History
The Inhuman that would become the Jailer was a criminal punished by the Council of Attilan to spend the rest of his life in a secret torture facility, repenting from his crimes until he died. He somehow managed to seize control of the prison, and took on the garb of his old captors. The new Jailer continued operating the prison, with his true nature remaining unrevealed. This way, the Jailer grew stronger, feeding for centuries on the pain and suffering of countless of inmates he tricked other jailers into handing over to him. As he became more powerful, the Jailer turned into an enormous monstrosity and split his body into tanks,[1] using a secondary humanoid form as a façade.[2]
One of the Jailer's last victims was the Inhuman king Black Bolt, unwittingly cast away by his wife Medusa in the place of his treacherous brother Maximus, who switched places with Black Bolt using image inducers before being sentenced to the space prison.[3] Together with other inmates, namely the Absorbing Man, Blinky, Raava, and Metal Master, Black Bolt attempted to break out of prison. They even managed to witness the Jailer's true form before being subdued.[4]
