The F.B.I, or Fed-up Bull Institute, is a group of evil super-intelligent cows who are the main villains in the Cows In Action series. They use time machines to try and interfere with history, making cows rule the world. Their best agents are a gang of cyborgs named ter-moo-nators who have had parts of their bodies replaced by machinery. They often replace figures in history with cows or have ter-moo-nators and other agents interact with local humans and educate native cattle for their future domination of Earth. They also use equally evil robot drones called Holly-Bats to mess up C.I.A time-travel missions.
