Isle of Giant Horrors

A deserted island which is not-so deserted. Somewhere on the island is a horrific giant beast. The telltale signs that it's there are usually giant footprints in the sand along the beach, the rumbling of footsteps or the clattering of trees being knocked down, and of course, a horrifying roar.

Usually, these types of creatures are the island's dominant species or ruler, lording over the place because they are the biggest and strongest. In some cases though, they are guardians protecting something residing on the island. Of course, there's also the possibility that the creature is trapped on the island, being surrounded by water on all sides makes it a good prison, in the event the creature cannot swim or is weak against water.

The type of creature that is usually the island's inhabitant can range from creatures from prehistoric times to everyday animals of the giant variety, especially crabs, spiders, and insects. Eldritch or Animalistic Abominations are not excluded from this. In some cases, the island can even be a domain of Mechanical Monsters. Of course, the visitor of the island might not even see what the beast is, due to perhaps being an Invisible Monster or perhaps just to invoke Nothing Is Scarier.

Can be an Island of Mystery if those that land are unaware of the creature residing on it at first. Usually used in a Trapped with Monster Plot, especially if the island's visitors are marooned. Different from Turtle Island, which is where an island is a creature, although it is not impossible that the moving island has a beast imprisoned on it. Similar to Beast in the Maze where a creature resides in a labyrinth instead of an island. If there is more than just one giant beast on the island, a Behemoth Battle is likely to happen between them. If the creature has a large stash of treasure, that is a Dragon Hoard. For a wider variety of monster dwellings, see Home of Monsters.

    Films — Live-Action 

  • Played with in Lord of the Flies. Most of the boys think there is a physical beast and by the end of the book start to almost worship it, but there is no "real" beast. The idea of the beast is actually used to represent of humanity's innate evil.
  • The Ur-Example is The Odyssey, where Odysseus and his crew dock on an island inhabited by a Cyclops named Polyphemus, who imprisons them in his cave and eats them two by two. They defeat the monster by stabbing his eye out with a stick.
  • The title character of Sinbad the Sailor often ends up on one of these during his travels, including one where a Roc bird nests, and another inhabited by a man-eating giant (who's basically an Expy of Polyphemus from The Odyssey and gets defeated in a similar manner).
  • Fragment: Henders Island is a remnant of an ancient supercontinent from the Precambrian era, where everything has been evolving separately for 570 million years and the inherent savagery of life has been turned up to eleven; an orgy of violence where the food chain is thrown out the window and everything eats everything - the dominant lifeform being a land-going species of mantis shrimp capable of single-hand(claw?)edly shredding and devouring tanks.

    Live-Action TV 
  • The Ultra Series has featured a couple over the years.
    • One of the first and best-known episodes of the original Ultraman was "The Lawless Monster Zone", in which the Science Patrol visit an island populated by various giant monsters like the dinosaur-like Red King, the bat-like Chandler, and a giant burrowing reptile called Magular. Another one appeared in their two-parter episode, this time home to relic dinosaur and Ensemble Darkhorse of the franchise Gomora.
    • In Ultraman Eighty, the characters find an abandoned island resort where an evil alien monster called Gimyra has hypnotized everyone on the island to drink their blood and turn them into its giant monster minions.
    • In one episode of Ultraman Dyna, the team visits an island populated by several monsters they have previously met. It soon turns out that the creatures are clones being used as practice targets for a Mad Scientist-made monster called Neosaurus.
    • Ultraman Max homaged the original example in a two-part episode featuring Red King, as well as two new monsters - a giant newt called Salamandon and a gliding reptile called Paragler. It's later revealed that the island is actually a dimension-hopping prison for Red King built by Atlantis, and the other two monsters are its guards.
    • Ultra Galaxy Mega Monster Battle kicks it up a notch with Bolis, an entire planet of giant horrors. Naturally, the story is that the main characters are stranded on the world in a botched space expedition and have to survive all the giant monsters (all pulled from previous series) that do nothing but attack anything they see.

    Real Life 
  • Island Gigantism, as Wikipedia states, is "a biological phenomenon in which the size of animals isolated on an island increases dramatically in comparison to their mainland relatives." Results in things like the Komodo Dragon (probably the closest thing to a Real Life example of this trope), the Elephant Bird (a flightless bird twice the size of an ostrich), and the Giant Tortoise of the Galápagos.
