Several of these villains are also featured in the Cataclysm storyline when an earthquake and the resulting tidal waves damage the prison and open up a land bridge to Gotham. This allows the majority of the inmates of Blackgate to escape. During the subsequent No Man's Land storyline, the master jailer Lock-Up took control of Blackgate, enlisting KGBeast and the Trigger Twins to act as wardens for his prison, and rules with an iron fist; Batman only tolerates his presence because he requires Lock-Up to keep captured criminals in check to prevent Gotham being overrun, although Lock-Up is under strict orders to treat the prisoners well.
