One of the most well-known comic prisons is Arkham Asylum, which first appeared in 1974’s Batman #258. Located on the outskirts of Gotham City, Arkham Asylum holds the most deranged and iconic Batman villains. While other villains are held at Blackgate Penitentiary, only the most dangerous cases make it to Arkham.

Unfortunately, it’s not the most effective prison at all. The doctors of Arkham have failed at almost every attempt at treatment or rehabilitation of villains like The Joker and Victor Zsasz. Arkham Asylum also has a bit of a revolving door, as criminals break out frequently. Even some of the staff have become villains over the years, like Dr. Harleen Quinzel’s corruption into Harley Quinn.

Finally, Gamma Base housed gamma-powered characters, though not very effectively.

Dr. Hank Pym and his many costumed identities designed a new prison that utilized his Pym Particles to shrink down supervillains. It became known as The Big House and focused on attempting to rehabilitate the shrunken villains. Unfortunately, the Big House experiment proved to be a failure. The criminals not only failed to be rehabilitated but they were also able to escape.

Hank Pym and Janet van Dyne worked together to create a second experimental prison. They again used Pym Particles to shrink down powered supervillains. They named it the Lang Memorial Penitentiary, though it was more commonly known as the Ant-Farm. This was due to the prison’s attempt to limit corruptible guards in the prison by using ants instead.

Portals at secured locations were the only access points, making the prison nearly inescapable. However, the prison eventually fell to the forces of Blastaar and was lost to the Negative Zone.

The Slab from DC Comics

Slabside Penitentiary was one of DC’s first supervillain prisons and was originally located in New Jersey. It became known as The Slab by the prisoners because the only way to get out of the prison was feet first. The Slab eventually hired a warden who specialized in escape artistry. Shilo Norman was the second Mister Miracle before he took on his new position at The Slab.

It became nearly escape-proof and was on track to becoming one of the most effective comic book prisons. However, The Joker released a powerful new toxin that launched a devastating riot. The Slab was ultimately lost in another dimension. When it returned to Earth, The Slab relocated to Antarctica which made it even more inescapable.

3 The Phantom Zone Is A Timeless Pocket Universe Created By Jor-El To Become A Kryptonian Prison

Phantom Zone

Superman inherited one of his father’s inventions known as the Phantom Zone Projector. It was capable of opening a doorway to a timeless parallel reality that was filled with criminals from Krypton. It wasn’t Superman’s favorite option, though he did use it to imprison some of Superman's most iconic villains like Doomsday and General Zod.

The Phantom Zone is incredibly effective because anyone trapped inside was turned into a ghost-like state. This negated any powers or abilities they had in the real world. Superman occasionally released imprisoned Kryptonians to the bottle city of Kandor after they fulfilled their sentences. While the Phantom Zone was escapable for some, it wasn’t an easy feat.

It was a high-tech ring of spherical moons that was policed by the galactic law enforcement group known as the Omega Corps. They transported prisoners from other groups like the Nova Corps or the Spaceknights to The Kyln.

The Kyln earned a reputation as a prison with a death sentence since most didn’t survive more than a few years inside. It held all kinds of galactic prisoners, which included characters like Star-Lord, Gladiator and Thanos at one point. The Kyln was even capable of containing powerful cosmic gods before it was destroyed by the Annihilation Wave.

Takron-Galtos first appeared in Adventure Comics #359 in the era of The Legion of Super-Heroes. The Science Police were the main jailers on Takron-Galtos, though the original members of the Legion of Super-Heroes assisted in stopping more than a few breakout attempts. Brainiac 5 eventually created an impenetrable force shield around the planet that made it even more effective.
