The MUTOs (ムートー Mūtō) are parasitic Titans who first appeared in the 2014 Legendary Pictures film Godzilla.

Prehistoric parasites that thrived at the same time as Godzilla's species, the MUTOs survived by attacking and killing members of Godzilla's species and laying their spores in their radioactive carcasses. Two MUTO spores left in the carcass of a Godzilla-like Titan known as Dagon survived for millions of years buried deep underground in the Philippines, only to be uncovered by a mining operation in 1999. A male MUTO emerged from its spore and began feeding on a nuclear reactor located in Janjira, while the female emerged from a nuclear waste storage facility in Nevada years later in 2014. The MUTOs met in San Francisco and began building a nest, but Godzilla arrived in the city to stop them from reproducing. After a long battle, Godzilla successfully killed both MUTOs, while the military destroyed the creatures' nest, successfully preventing the MUTOs from repopulating. As Godzilla's foes in the first entry of the Monsterverse, the MUTOs were the first opponent faced by Godzilla in a film since Monster X 10 years earlier. A second female dubbed the Queen MUTO[3] made a brief appearance in the film's sequel, Godzilla: King of the Monsters, as part of the Titan army rampaging around the world.
