Superheroes have their headquarters, but so do supervillains. Of course, trying to thwart those do-gooders takes some time, and even supervillains need a place that not only is conducive to world domination, but also allows them to relax and play air hockey in-between. Or any other game that helps them keep up their mood for world conquest.
The super-evil chill pad/headquarters can reflect something of the villain's personality, which is also clutch. And yes, don't forget, it probably has a chamber or a dungeon for imprisoning the villain's dreaded enemies. Check out this list of the all-time most awesomely bad supervillain lairs.
The Death Star
The most ominous and among the largest, the Death Star is considered the very embodiment of galactic terror. It's home to among the evilest guys in space and can blow up a planet. Although they should do something about vulnerable vents. And one wonders where they got enough materials to build it.
Lex Luthor, Superman's nemesis, makes up for his lack of super-powers with his being a brilliant scientist and businessman - and even president of the United States. Of course, Luthor does it from his LexCorp headquarters, the cartoon version featured here.
Skeletor's Snake Mountain
The evil counterpart to Castle GraySkull, Snake Mountain is one heck of a lair. That giant snake winding around giant rocks leaves you no doubt: it's an evil guy's place. You even wonder if it'll come to life to eat up He-Man like Thor vs. Jormungandr.
Magneto's Asteroid M
Among the supervillains taking to space for refuge, Magneto has this neat asteroid retreat where he hid away for a while until some psychotic wacko convinced him to get back to villainy. These days, however, he helps out the X-Men and other mutants.
But for a time, he did seem unreachable in space.
