Mechagodzilla (Japanese: メカゴジラ, Hepburn: Mekagojira) is a mecha kaiju (a giant robotic monster) who first appeared in the 1974 film, Godzilla vs. Mechagodzilla. In the Showa era Godzilla films, Mechagodzilla is depicted as being constructed by extraterrestrial invaders to confront and destroy Godzilla. In the subsequent Heisei era, Millennium era and Monsterverse films, it is usually depicted as a man-made weapon designed to defend against Godzilla and other kaiju. The character is portrayed as a robotic counterpart of Godzilla with a vast array of high-tech weaponry. Along with King Ghidorah, Mechagodzilla is commonly considered to be an archenemy of Godzilla.
