MFS-3 Type 3-Kiryu (機龍), also known as Mechagodzilla 3, is a cyborg built around the skeleton of the original Godzilla by the Japanese Self-Defense Forces that appeared in the movies Godzilla Against Mechagodzilla in 2002 and Godzilla: Tokyo S.O.S. in 2003.
Due to being built around the first Godzilla's skeleton, Kiryu resembles Godzilla more than the other Mechagodzillas. Kiryu retains some of the physical features present on Mechagodzilla and Mechagodzilla 2, but features a sleeker and more organic design. Kiryu is 60 meters tall, 120 meters long, and weighs 40,000 tons.
Kiryu was constructed around the skeleton of the first Godzilla that was killed by the Oxygen Destroyer in 1954. Kiryu was intended to defend the nation against inevitable attacks by Godzilla and other giant monsters.
