- "Not much I can do about that in here."
- ―Edison Po
Havenworth Federal Penitentiary is a penal facility in the United States of America.
Imprisonment of Edison Po
Edison Po was imprisoned at Havenworth for stabbing a man in the eye with a steak knife in Boston, Massachusetts. As Po revealed to Raina, he attacked the man for asking too many questions about the Clairvoyant.
Touching the Clairvoyant
Raina visited Edison Po to inform him about the death of Debbie, the stabilization of the Extremis element in the Centipede Serum and the interference of Phil Coulson and his team of S.H.I.E.L.D. agents.
As Po could not do much about these situations inside the prison, Raina asked him to touch base with the Clairvoyant to see if he could give insights about stage three of their plan to create super soldiers. Po replied that the Clairvoyant didn't like to be touched, but Raina told him that all of them should do things they didn't like in order to complete their project.
Liberation of Edison Po
Edison Po was having breakfast in the dining hall of the prison alone. A fellow inmate, Tiny, tried to sit at the same table where Po was sit. However Po informed him that the seat was already taken, despite it being empty, so Tiny left to take another seat, as a show of either fear or respect to Po.
A group of Centipede Soldiers led by Brian Hayward opened a hole in the ceiling of the dining hall in order to break Po out of prison. The soldiers easily defeated the prison guards, but Po was unshaken by the attack, calmly eating his breakfast while Hayward and the other soldiers disposed of the guards.
Hayward informed Po that it was time to go, and Po told Hayward he should be calling him "sir", before leaving the prison in a helicopter with the three Centipede Soldiers.
- Its name is probably taken from real life Leavenworth Penitentiary.
