   Godzilla Bermudez says that Godzilla is one of the most recognizable movie monsters of all time. TV and film content creator Danbo says that Godzilla basically "created the basis for large and scaling monsters." Known as the King of Monsters, Godzilla is a giant, lizard-like sea monster, first introduced in 1954. Depending on the adaptation, he’s either a massive, destructive force or a guardian of Earth. He’s appeared in numerous movies, TV shows, comic books, and video games.

   King Ghidorah First introduced in 1964’s Ghidorah, the Three-Headed Monster, Ghidorah is a giant, three-headed dragon who happens to be Godzilla’s mortal enemy. He comes from outer space and intends to destroy the world, and he often battles Godzilla for the title of “King of the Monsters.”

   Gamera Created to compete with Godzilla, Gamera is a giant, fire-breathing turtle. When he pulls his arms and legs into his shell, he emits rocket power, allowing him to fly through the air. While originally a destructive monster, he’s better known for being a heroic protector of Earth and human children specifically.
5. 
   5
   Mothra The titular character of 1961’s Mothra, Mothra is a giant, sentient moth. Unlike most giant movie monsters, Mothra is benevolent and serves as a protector of Earth. She often appears in movies with Godzilla. Mothra is also one of the only female-coded giant monsters in film.
6.

   Clover (Cloverfield Monster) Bermudez says that Clover is a great modern example of a giant monster. The Cloverfield Monster is the main antagonist in 2008’s Cloverfield. Though it hardly appears in the film, it’s a force to be reckoned with. Believed to be a baby, it’s powerful enough to rip the head off of the Statue of Liberty and destroy the Empire State Building. Its origins are never fully addressed in the film, but it’s a deep-sea creature whose face somewhat resembles a piranha.
7. 
   7
   Mechagodzilla Another one of Godzilla’s nemeses is Mechagodzilla—a giant, robotic version of Godzilla. In some films, he was created by aliens to take over Earth, while in others, humans created him as a defense weapon. No matter how he was created, he’s always incredibly strong and nearly impenetrable.
8. 
   8
   Konga Created as an homage to King Kong, Konga is a giant ape monster that was created after a scientist experimented on a baby chimpanzee. The scientist then hypnotized Konga and caused him to go on a killing spree. This monster was introduced in 1961’s Konga.
9. 
   9
   Rodan Introduced in 1956’s Rodan, this giant monster resembles a pteranodon and has frequently been featured in the Godzilla franchise. After being awoken by nuclear radiation, Rodan fled Mount Aso in Japan to wreak havoc on the world. He typically has brown or burgundy skin with spikes on his chest and 2 or 3 horns on his head. Originally an antagonist, he sometimes acts as a protector like other monsters in the Godzilla universe.
10. 
    10
    Kumonga If you have arachnophobia, stay away—Kumonga is a giant spider that first appeared in 1967’s Son of Godzilla. His body is black with yellow stripes, and he’s known to attack anything he sees. Kumonga is mostly portrayed as a destructive monster, but in some instances, he teams up with other monsters to defeat a bigger threat.
11. 
    11
    Biollante Biollante is perhaps one of the most unique giant monsters, as it was created from the DNA of Godzilla, a rose, and the deceased daughter of the scientist who created it. It has two forms: it can appear as a giant rosebud with teeth inside the petals or as a giant monster that resembles a crocodile with tentacles and tusks. Biollante first appeared in 1989’s Godzilla vs. Biollante.
