The best thing about Part Two? No long-winded introductory paragraph! Picking up where Part One left off, let's get to numbers five through one:

The JLA Satellite: Leaving their original cave hangout behind, the League moved into a spiffy new orbiting satellite in Justice League #78 (1970), undoubtedly inspired by the space station in 2001: A Space Odyssey (1968). Despite the "America" portion of the team's name, the satellite seemed to elevate the League's mission to that of international or even planetary protectors. In the years since the satellite's destruction, the JLA have steadily increased the "wow" factor of their succeeding headquarters (at one point building one on the moon)...but none of them quite surpass the groovy space-age vibe of that ol' satellite.
Latveria: In the early days of Marvel Comics, creators Stan Lee and Jack Kirby were determined to shake up the status quo. One of their many, many innovations was a Fantastic Four villain named Doctor Doom who, in addition to a compelling appearance and origin story, took the concept of the bad guy's lair to a completely new category. Instead of holing up in a building or even a compound, Doom's home base was an entire country...and he its beloved monarch! Located somewhere in Eastern Europe, the sovereign nation of Latveria was strictly ruled and fiercely protected by Doom and his advanced technology...which often made the Fantastic Four's efforts to stop him a diplomatically sticky situation.


The Tower of Fate: As one of the coolest heroes of the fabled Golden Age of Comics, sorcerer Doctor Fate had a headquarters that perfectly complemented his eerie modus operandi. Its Earthly aspect located in (a perpetually overcast) Salem, Massachusetts, this windowless and doorless tower could only be entered by Fate and his wife Inza. Inside were countless magical artifacts, weapons, and tomes dating back to the ancient world. Much like the Rock of Eternity (yesterday's #9), this stark, lonely structure exists outside of conventional space and time...and has recently been shown to have a bewildering, Escher-esque interior.
The Fortress of Solitude: God knows, I've said almost everything I could possibly say about Superman's Fortress of Solitude...but I have to reiterate just how much I love the concept of the Man of Steel needing a place to relax and unwind. Sure, he had the obligatory headquarters stuff like super-computers and trophy rooms...but first and foremost, the Fortress was a place for Superman to chill the heck out! (no arctic-pun intended). My favorite of its many iterations was, of course, the version featured from 1957 through 1986 which, as you can read about here, is intertwined with my first-ever encounter with the Superman character.
As much as I love the Fortress of Solitude, it was narrowly edged out by my top pick...which by now should be obvious to just about anyone who's read a comic book. The number one Comic Book Headquarters is, of course....

The Original Legion of Superheroes Clubhouse: Made from a semi-buried, upside-down rocketship, the headquarters of the futuristic Legion of Superheroes was....
Okay, you didn't seriously think I picked this as #1, did you?
All right, all right...the real number one can only be...
The Batcave: The perfect expression of the secret headquarters concept, the Batcave simply can't be surpassed in its thematic compatibility with its hero and its sheer mythic weight. Mostly utilitarian, with intriguing touches of sentimentality, the sprawling underground complex is a breathtaking testament to the lengths Bruce Wayne has gone to avenge his parents' deaths.
