Although not the first giant robot, or even the first to fight a kaiju, this design was the first to prove that giant robots could be consistently effective as weapons. Originally designed by an extraterrestrial invasion force as a vanguard, two were deployed on Earth in two different invasion attempts: one in 1974 (“MG”), and one in 1975 (“MG2“) as part of a joint human-alien invasion attempt. This second Mechagodzilla was salvaged by the United Nations, reconstructed and reverse-engineered, and used as a prototype for the production of three new Mechagodzilla robots of the same design. By 1977 there were four operational Mechagodzilla units stationed across the globe: one in Europe (MG2), one in Asia (MG3), one in Oceania and the South Pacific (MG4), and one in America (MG5). Although just a year later construction had already begun on the more advanced Mechagodzilla Mk. II, these four machines served as the main defense against kaiju attacks until the last one, “MG3,” was retired in 1991.
Despite being constructed using advanced alien technology, the Mk. I Mechagodzilla is the most primitive of the Mechagodzilla designs. It possesses a wide range of weapons and formidable artillery compared to its successors, but it lacks effective close-range weaponry, and its armor is considerably less durable. As an invasion weapon, “shock and awe” were among the foremost concerns of its designers, and often took precedence over strict practicality. Despite their known disadvantages in certain areas, however, the Mk. I proved to be a formidable weapon in battle, and provided some advantages over later designs, leading to some controversy as to whether or not the design should ever have been discontinued. The Mk. I had already been designed and tested by the time it first appeared on Earth, and the corners cut during its production could lead to construction times as fast as 14 months, while later, more advanced machines could take well over a decade to complete.
Two of the Earth-built units, “MG2” and “MG3,” remain in existence, but neither is operational. All other Earth-built units were destroyed in battle and subsequently dismantled. It is, however, believed that the design is still used on other planets.
