Fortress of Solitude






31st century

First Appearance

Message in a Bottle


In the 21st century, Superman created a secret headquarters in the Arctic amid an isolated mountain range. To ensure no one could enter, the key to the Fortress required enhanced strength to carry it for miles, then lift it to the doorway, and use it. Superman later cloaked the key with a hologram. Very few of his allies and friends know the Fortress' location, including Lois Lane, Batman, and Wonder Woman.

The main lobby houses a giant memorial statue of Superman's parents, Jor-El and Lara, holding the planet Krypton. Much like the Batcave, several rooms are dedicated to souvenirs that Superman collected over his career. An armory houses weapons he confiscated on alien planets.

Of more practical use, Superman has a hangar bay for his Supermobile, a crime lab with state of the art forensics technology, and a monitoring station. In his spare time, Superman was known to experiment on samples of Kryptonite to find a way to erase its effects. He also maintains a zoo of alien species that he encountered over the years. They are mainly endangered species whose planet was destroyed and Superman feels a kinship to. The shrunken city of Kandor resides in the Fortress, as well. The Phantom Zone Projector was also kept in the Fortress but wound up in a public collection in the 30th century. Aware of his mortality, he constructed Superman Robot's in his likeness to maintain the Fortress in his absence and eventual death.

Over the years, several super villains have infiltrated the Fortress. In the 31st century, Imperiex invaded the Fortress in search of Kandor and a powerful technology.
