Monsters vs. Aliens is a media franchise made by DreamWorks Animation. The franchise began with the 2009 film Monsters vs. Aliens and has since grown to include two short films, a television special, a television series, and a tie-in video game.
The franchise follows a group of monsters: Susan (also called Ginormica), a woman who was struck by an asteroid on her wedding day and grew to be 50 feet tall; B.O.B., an indestructible gelatinous mass who was created when a dessert topping was crossed with a tomato; The Missing Link, a 20,000-year-old macho fish man, who was thawed out from deep ice by scientists; Dr. Cockroach, Ph.D., a scientist who became a bug guy after his experiment went wrong; and Insectosaurus, a massive bug who was mutated by nuclear radiation. The monsters are assigned by the U.S. Government to defend Earth from alien invasions and supernatural threats.
