Godzilla is the main character of the frachise of the same name. He is the King of the Monsters and first appeared in 1954 in the film Gojira, produced in Japan by the Toho Company Ltd., and since then, there has been an impressive number of 28 Godzilla films produced. He is a 50-100 meter kaiju that can shoot nuclear beam from out of his mouth.
Godzilla was a giant dinosaur called the Godzillasaurus that was mutated by a failed bomb test. Godzilla started off as a giant bringer of destruction and a danger to humanity, but as the series went on he became more of an actual character with an arrogant and stubborn personality but was also caring and loyal. Godzilla reformed when Japan was in endangered by King Ghidorah and helped fight the space monster. After this event, Godzilla's sides have varied, usually a protector of humanity but sometimes danger to humanity. Godzilla has been played by numerous actors throughout the years, and the effects were usually a man in a rubber suit. This is Japan's most common way to portray monsters, and many have noticed that Godzilla indeed does look like a rubber monster, but he has nevertheless become one of the most famous monsters put on screen, arguably only rivaled in popularity by King Kong, who Godzilla has actually fought against in King Kong vs. Godzilla.
Godzilla has remained a popular figure in Japanese pop culture, though he has lost some popularity over the years he still remains one of the best known giant monsters ever.
Godzilla's appearance has changed between films over the years, but many defining details have endured. In the Japanese films, Godzilla is depicted as a gigantic dinosaur with rough, bumpy, usally charcoal gray scales, a long powerful tail, and generally bone-white dorsal plates, generally shaped like maple leaves, thought there are some designs whose traits may differ. His origins vary somewhat from film to film, but he is almost described as a prehistoric creature, and his first attacks on Japan are linked to the beginning of the Atomic Age. In particular, mutation due to atomic radiation is presented as an explanation for his great size and strange powers. Godzilla's iconic design is composed of a mixture of various species of dinosaurus; specifically, he has the body and overall shape of an old model of a Tyrannosarus Rex, the long arms of an Iguanodon, and the dorsal plates of a Stegosarus.
As a Villain
Godzilla was originally a dinosaur called Godzillasaurus (revealed in Godzilla vs. King Ghidorah (1991), who was then mutated by nuclear testing. He destroyed multiplie fishing boats, When investigors arrived on Odo Island, they learned that the native islanders belived the attacks were caused by a sea-god named Godzilla (Japanese name Gojira), and when the island wee attacked by the mutant, the name stuck. Godzilla attacked Tokyo multiplie times until he was killed by the Oxygen Destroyer, a powerful weapon created by Dr. Serizawa.
In the later movies, either a second Godzilla exists, or Godzilla survived the oxygen destroyer. In Godzilla, Mothra, and King Ghidorah: Giant Monsters All Out Attack, Godzilla has been dead for years and has become nothing but a legend that some do not belive in, however the souls of those who died in World War II merge and create another Godzilla.
As a Hero
In some films, Godzilla becomes the lesser of two evils and saves the world from alien threats, such as King Ghidorah, or human spawned creations, such as Hedorah. When portrayed as a protagonist, Godzilla is either a heroic monster, a caring but strict parent, or animal trying to find it's place in the world as the last of it's kind. It is to be noted that Godzilla defends Earth only,
