is a fictional mecha character that first appeared in the 1974 film Godzilla vs. Mechagodzilla. In its debut appearance, Mechagodzilla is depicted as an extraterrestrial villain that confronts Godzilla. In subsequent iterations, Mechagodzilla is usually depicted as a man-made weapon designed to defend Japan from Godzilla. In all incarnations, the character is portrayed as a robotic doppelgänger with a vast array of weaponry, and along with King Ghidorah, is commonly considered to be an archenemy of Godzilla. Overview Development Mechagodzilla was conceived in 1974 as a more serious villain than its immediate two predecessors, Gigan and Megalon, whose films were considered creative disasters. According to Tomoyuki Tanaka, Mechagodzilla was inspired by both Mechani-Kong from the previous Toho film King Kong Escapes and the robot anime genre, which was popular at the time. Effects director Teruyoshi Nakano also felt that a mechanical monster was cheaper to construct than the mutated animals Godzilla had previously faced. As the resulting Godzilla vs. Mechagodzilla proved to be a greater critical success than previous 1970s Godzilla films, the character was revived in 1975's Terror of Mechagodzilla. The film's screenplay was based on the winning entry of a story-writing competition won by Yukiko Takayama, who continued the darker tone of the previous film by adding the subplot of Mechagodzilla being cybernetically connected to a young woman. Mechagodzilla's design remained largely unchanged from its previous appearance, though it was made to look thinner and more angular, with a darker sheen and an MG2 insignia emblazoned on its upper arms. The film's original draft was going to have Mechagodzilla destroy Tokyo utterly, though the destruction was cut down for budgetary reasons. Mechagodzilla was brought back in 1993's Godzilla vs. Mechagodzilla II, as the success of Godzilla vs. Mothra and the popularity of its main antagonist Mothra spurred Toho into reintroducing familiar characters rather than inventing new ones. Originally, the new Mechagodzilla was to be named "Berserk", and was envisioned as being a much more organic Godzilla-like creature which would later turn on its creators after becoming infected with a computer virus which makes it self-aware. Berserk would subsequently absorb more and more machinery, to the point of degenerating into a mass of metal and wires, though this concept was rejected early in pre-production. As Mechagodzilla was intended to be a military defense weapon rather than an alien construct, the character was redesigned as looking sleeker and smoother. It
