Prison 42

42 in the Negative Zone

42 is a special prison that resides in the Negative Zone. It was designed by Reed Richards, Tony Stark and Hank Pym as the 42nd idea for their plans to make the world a more secure and better place. The only entrance and exit to the prison is through the portal that resides somewhere in the Baxter Building and is guarded by the elite Mandroids of S.H.I.E.L.D. The inside of the prison is guarded by the Ultron units and are programmed to rehabilitate the prisoners. After they were used to even the odds against Kang they were replaced by the S.H.I.E.L.D. agents, because during the invasion of Kang, only one Ultron remained. 42 was abandoned when it was discovered there was life in the Negative Zone that would use the portal to Earth to crush all the positive matter. The Hydro-Base was built to contain all prisoners instead.
