A Supervillain Lair
(or a Hero's Headquarters) At Sea! Isolated from any inference of those pesky heroes, our resident baddies can concoct their schemes of world domination in peace. At least until the third act.
Bonus points if the island, or part of it, is shaped like a skull. Extra points for having an active volcano form part of the base
, despite the obvious problems with heat
keeping such things from being practical in real life.

Anime and Manga
- Dungeon Keeper Ami features several- all of which score bonus points for covering the active volcano, skull-shaped cave, and so on. Just not all at the same time. Zarekos' Islands were riddled with lava-filled fissures, due to the tremendous dark energy contamination, which Ami inherited from him, following his deafeat. Ami, naturally repurposed them for use as geothermal plants. Later, the battle of Dreadfog Island takes place on an island in a large swamp- and the island sports a skull-shaped cave incorporated into the fortifications.

- Swellhead. The protagonists are sent to investigate strange events on the long-deserted and distant island of Skerra, somewhere on the ill-defined border between Britain and Island which for historical reasons even has a monarchy (not that she's ever set foot on the island before now) and is therefore an independent nation. Turns out an Elaborate Underground Base has been discovered on Skerra, despite the sheer impossibility of constructing one without vast resources and public knowledge. One which, as they delve further into it, looks increasingly like a classic Supervillain Lair...

- In both Rymdjakten (The Space Hunt) and Djuphavsjakten (The Deep Sea Hunt), the heroes are headquartered on an island solely owned and inhabited by them. They start out rather mundane, with just the home of the person(s) who discovered the central issue of the game and some kind of facility relevant to the game (an observatory in Rymdjakten, a lighthouse in Djuphavsjakten), but by the later portions they include, among other things, training facilities (for astronauts in Rymdjakten, and for divers and dolphins in Djuphavsjakten), construction facilities, laboratories, and in Rymdjakten two rocket launching pads. In both games, all of this is privately owned.

- World War 2 involved a lot of these, which include:
- The Hawaiian Islands, specifically Oahu and Pearl Harbor
- Fort Drum (AKA the concrete battleship) in Manila Bay

- Iwo Jima
- Possibly Japan and Britain on a large scale (see also below)
- During the Cold War, several U.S. allies acted like these as they hosted US military personnel; most notable were (and still are) the UK and Japan as they are actual islands, as well as Iceland (which didn't and still doesn't have a military when it joined NATO) and Taiwan (prior to the establishing of diplomatic ties between the US and China in 1979). Islands need not be purely geographical, either - Alexander Haig, Secretary of State under Ronald Reagan, called Israel the US's largest unsinkable aircraft carrier in the Middle East.
- Chagos Archipelago
- It houses a massive US military base at Diego Garcia. It was used for reconnaissance in the 1973 Arab-Israeli war and saw wartime use in the first Gulf War. After 9/11 it was key to the wars in Afghanistan and Iraq. It may house nuclear weapons and may be a "black site" for detaining prisoners. It is more secretive than Guantanamo Bay - which is probably why most people have never heard of it.
- In a true supervillain fashion, forty years ago, its people, the Chagossians, were unceremoniously removed from their homeland by a joint operation of the United Kingdom and the United States, and essentially left beached in Mauritius as human detritus. This was detailed in David Vine's book Island of Shame: the Secret History of the US Military Base on Diego Garcia.

- Mobile offshore bases are a proposed idea of combining this trope with Base on Wheels (we suppose it'd then be a Base On Hulls) so as to be able to extend force projection far beyond one's own shores (i.e., the US's) while still remaining in international waters and thus avoid a lot of political problems associated with (American) bases and personnel stationed overseas (e.g., Saudi Arabia, Okinawa).
