Monsterland and Monster Island
Monsterland was introduced in the 1968 film Destroy All Monsters. The United Nations had decided to gather all the Earth's daikaiju (giant monsters) and corral them into a single location, then keep them there. The Ogasawara Islands were chosen for the project and by 1999 ("at the end of the 20th century" in the original Japanese version), Godzilla, Rodan, Mothra, Anguirus, Gorosaurus, Kumonga, Minilla, Baragon, Manda, and Varan were all residents of Monsterland. Various security devices were installed on the island to make sure the daikaiju wouldn't escape. Among the various devices were machines that sprayed different types of mist that Godzilla and Mothra shied away from, as well as a magnetic wall that prevented Rodan from flying away.
All was well until the Kilaaks invaded, taking control of Monsterland and letting loose the monsters upon the world. After the Kilaaks were foiled, the monsters returned to Monsterland and have been living there since.
Monster Island first appeared in Destroy All Monsters, where all the monsters have been collected and contained on. In 1969's All Monsters Attack, a young boy named Ichiro dreamed of being on Monster Island. He dreamt of befriending Minilla and watching him and Godzilla battle other monsters. In the dream, the daikaiju living on Monster Island included Godzilla, Minilla, Gabara, Kamacuras (3 of them), Kumonga, Ebirah, Anguirus, Gorosaurus, Manda, the Giant Condor from Godzilla vs. the Sea Monster, Maneater (a plant man that grabs Ichiro in the jungle, and Rodan (mentioned but unseen).
Monster Island appeared again in Godzilla vs. Megalon (1973), one of many locations suffering the effects of nuclear testing. This is seen to disturb Godzilla, Rodan, and Anguirus; as they try to escape the explosions, Anguirus falls into a crevasse in the ground. Rodan's fate was never revealed, though it can be assumed he flew away safely. Godzilla was summoned from Monster Island in a few of the episodes of the television series Zone Fighter, to assist the giant superhero, specifically the first episode that Godzilla appeared in. These Zone Fighter episodes are considered by Toho to be canon.
It is commonly speculated to be Solgell Island from Son of Godzilla due to the timing of introduction and presence of Godzilla, Minilla, Kamacuras and Kumonga, all kajiu who had been previously seen on the island whereas most other kajiu had not had set locations of origin. As well, the island is referred to as "Monster Island" in the Japanese version of the film, most notably the title.
Monsters on the island
In a script that was never produced, Maguma (Gorath (1962)) was also on the island.
Godzilla: The Series
Another version of Monster Island existed in Godzilla: The Series, the continuation of the 1998 film Godzilla. It is given the codename: SITE OMEGA. This island was originally the base of operations for the Tachyon aliens, as proposed by Major Hicks. This island eventually became home to Crustaceous Rex, King Cobra, the Giant Bat, Skeetera, the mutant humming birds and possibly the Shrewster as well as the combined monster population of the Mutant colesium and mutant mania circus. Godzilla also visited the island occasionally, though because he traveled with H.E.A.T. he never became a permanent resident. Large, cage-like apparatuses were installed on the island to keep the daikaiju isolated from each other, and they remain on Monster Island to this day. At one point, the base was infiltrated by an organization of ecoterrorists called S.C.A.L.E. who tried to free the monsters, which only resulted in a large scale battle between the beasts before they were imprisoned once again. In the series, Monster Island was originally called Isla de Diablo.
In an alternate timeline, Monster Island fell under siege by the invincible Dragma creatures, and every daikaiju (including Godzilla) that fought to protect a large number of humans and given a hero's commemoration via a statue, were slaughtered by their might.
A real "monster"
On September 27, 2005, the first filmed evidence of a live "Architeuthis" (Giant Squid) in the wild was shot off near Ogasawara Islands, the islands which were used in much of the Godzilla mythos as being "Monster Island".
In popular culture
Several references to "Monster Island" are likely based on this element from the Godzilla series.
- The Simpsons: In the episode "Lisa on Ice", Lisa imagines being sentenced to Monster Island for failing Physical Education. The judge informs her that the term "Monster Island" is just a name, but Lisa discovers that the island is in fact the home of several daikaiju. Fleeing from the giant creatures (which are Mothra, Rodan, and Gamera), Lisa is informed by one of her fellow inmates that what the judge meant was that Monster Island is in fact a peninsula.
- The Monsta Island Czars are a hip-hop group from New York City, most of whose individual names are parodies of daikaiju names.
- In Warren Ellis' s Planetary series, there is Island Zero, home to many kaiju, including what is apparently King Ghidorah, Godzilla and Mothra, all dead. A green, flying kaiju similar to Rodan has, however, survived.
- In DC Comics, Dinosaur Island was often called Mystery Island or Monster Island during the its initial appearances in the pages of Star Spangled War Stories.
- On Buffy the Vampire Slayer, Xander Harris likes living near the Hellmouth rather than living on Monster Island.
- The Grim Adventures of Billy & Mandy: In the Cartoon Network original movie Billy and Mandy's Big Boogey Adventure, the race that Team Grim and Team Boogey had to go through to win the privilege to fight Horror included getting past Monster Island, and encountered the Toho monsters Godzilla, Anguirus, Rodan, King Ghidorah, Gigan, and Gamera. Interestingly enough, Godzilla has his roar from the Heisei series.
- The Powerpuff Girls: In the episode "Super Zeroes", a giant slimy teal blob-like monster named Steven explains to the girls that going to Townsville to encounter the Powerpuff Girls and return (alive) from fighting them is a symbol of honor on Monster Isle, where most of the show's city-destroying antagonists reside.
- Top Ten includes a character named Gograh (a Godzilla-like monster) who is said to live on 'Monster Atoll' (presumably an island near Neopolis) with other giant monsters.
- In Scott Ciencin's Godzilla junior novels, Monster Island first existed as a government research facility created to study Anguirus and Rodan. Eventually, through the psychic influence of a pair of children, Godzilla and a troop of other monsters (including Varan, Kamacuras, Kumonga, and several over-sized animals) travel to the island and make it their new home.
- Monster Island is a playable arena in the videogames Godzilla: Destroy All Monsters Melee, Godzilla: Save the Earth and Godzilla: Unleashed. In the latter, it has, like the game's other arenas, been affected by the spread of alien crystals. Early speculation was that the island would be partially flooded, but the arena is the same as that in the first two games other than the presence of the crystals. Producer Shelby Wills explained that the island is the "starting point" for the playable faction, Earth Defenders, in the game and so it does not show the same signs of apocalyptic damage as the game's other environments.
- Monster Island has also returned in IDW comic's Godzilla canon, particularly the Godzilla: Gangsters and Goliaths miniseries.
