Susan Murphy (Reese Witherspoon) of Modesto, California is going to be married to news weatherman Derek Dietl (Paul Rudd). Just before the ceremony though she appears unharmed at first, But before the ceremony, she gets hit by a meteorite and she is hit by an meteorite from a destroyed planet strikes her and its radiation is absorbed into her body during the ceremony, the energy causes to glow green and As a side-effect, Susan's brown hair to turn white, and Its energy causes her to grow uncontrollably during the ceremony as it turn her into a 50 foot-tall giantess, destroying a church in the process. She is tranquilized by the military and awakens in a top secret government facility that houses monsters without human knowledge. She meets the warden W.R. Monger, and fellow inmates: Dr. Cockroach P.H.D. (Hugh Laurie), a mad scientist who became half cockroach after an experiment; B.O.B. (Benzoate Ostylezene Bicarbonate) (Seth Rogen), a brainless, living mass of goo as a result of a food flavoring mutation; Insectosaurus, a mutated bug standing at 350 feet in height, and the Missing Link (Will Arnett), a prehistoric fish man who was thawed from deep ice. Susan herself has been renamed to Ginormica.

In deep space, an alien overlord named Gallaxhar (Rainn Wilson) is alerted to the presence of quantonium, a powerful energy source on Earth, and he sends a probe to retrieve it. The probe later lands on Earth where the President of the United States (Stephen Colbert) attempts to make first contact with it. However, the attempt fails and the probe goes on a destructive rampage, headed straight for San Francisco. Monger arranges for the freedom of the monsters if they can stop the probe to which the president agrees. The robot detects the quantonium radiating through Susan's body and tries to take it from her. The monsters work together to save the people and defeat the probe.

Unbeknownst to the monsters, Gallaxhar sets course for Earth to obtain the quantonium in person while the now-free Susan returns home with her new friends and reunites with her family. However, the monsters alienate themselves from the humans due to their inexperience with social situations. Derek later breaks off his engagement with Susan, believing that he cannot marry someone who would overshadow him and his career. Heartbroken, the monsters reunite, but Susan realizes that her life is better as a monster and promises not to sell herself short to anyone again.

Initially heartbroken, Ginormica finally realizes that her life was even better as a monster and she promises the other monsters to never underestimate herself again. Suddenly, Ginormica is pulled into Gallaxhar's ship by a tractor beam. Insectosaurus tries to save her, but is shot down by the ship and seemingly killed.

Onboard the ship, Ginormica furiously breaks free from her prison cell and chases down Gallaxhar, only to be trapped by a machine that extracts the quantonium from her body, shrinking her back to her original size. Gallaxhar then uses the extracted quantonium to create clones of himself in order to launch a full-scale invasion of Earth. Monger manages to get the other monsters on board the ship, where they rescue Ginormica and make their way to the main power core where Dr. Cockroach sets the ship to self-destruct to prevent the invasion. Ginormica personally confronts Gallaxhar on the bridge. With time running out, she sends the ball of stored quantonium down on herself, restoring her monstrous size and strength. After rescuing her friends, they flee the ship and are rescued by Monger and Insectosaurus, who has metamorphosed into a giant butterfly. The ship then self-destructs, killing Gallaxhar and his army.

Returning to Modesto, Ginormica, B.O.B, Dr. Cockroach, the Missing Link, and Insectosaurus receive a hero's welcome. Hoping to take advantage of Ginormica’s fame for his own career, Derek tries to get back together with her and gain an interview, but she rejects and humiliates him live on camera. Monger then arrives to inform the monsters that a monstrous snail named "Escargantua" is slowly making its way to Parisafter falling into a nuclear reactor, resulting in the heroes taking off to confront the new menace.

## Cast

Main article: List of Monsters vs. Aliens characters

### Monsters[edit]

Reese Witherspoon at the British premiere of the film.

* Reese Witherspoon as Susan Murphy / Ginormica, a woman from ***Modesto, California*** who is hit by a radioactive quantonium meteorite on her wedding day, causing her to change drastically and grow to a height of 50 feet 11.5 inches (15.532 m) and into a white-haired giantess. Her exposure to quantonium also makes her hair color change and turn from brown to white and gives her super-strength and physical-imperviousness.
* Seth Rogen as B.O.B. (***Benzoate*** Ostylezene ***Bicarbonate***), an indestructible gelatinous mass created when a tomato was injected with a genetically-modified ranch-flavored dessert topping. He can devour and digest almost any substance. Despite having consciousness, he literally and figuratively lacks a brain and is thus the comic relief.
* Hugh Laurie as Dr. Cockroach ***Ph.D.***, a brilliant ***scientist*** who attempted to imbue himself with the resilience and abilities of a ***cockroach***, with the side effect of his head becoming that of a giant cockroach.
* Will Arnett as The Missing Link (usually referred to as "Link"), a 20,000-year-old fish-ape ***humanoid*** who was found frozen and thawed out by scientists, only to escape and wreak havoc at his old lagoon habitat of ***Cocoa Beach, Florida***.
* Insectosaurus, formerly a 1 inch (25 mm) ***grub*** transformed and mutated by nuclear ***radiation*** into a 350 foot (106.7 m) monster with the ability to shoot ***silk*** out of his nose. He is unable to speak clearly and is mesmerized by bright light. He has a close bond with Link, who can understand what he's saying.

### Aliens[edit]

* Rainn Wilson as Gallaxhar, an evil alien overlord intent on collecting quantonium – the substance that transformed Susan into Ginormica – to give his cloning machine enough power to generate an army of clones of himself to conquer Earth. He is served by gigantic robotic probes. He claims to have suffered several traumas in his youth (which are left mostly unintelligible to the viewer, due to him telling Ginormica his story while being repeatedly ***photocopied*** to create his clones), driving him to destroy his own homeworld, and plans to make a new one on Earth.
* Amy Poehler as Gallaxhar's computer.

### Humans[edit]

* Kiefer Sutherland as General W. R. Monger, a military leader who runs a top-secret facility where monsters are kept, it is his plan to fight the invading aliens with the imprisoned monsters in exchange for their freedom. In a scene during the credits, he claims to be 90 years old, in spite of his youthful appearance.
* ***Stephen Colbert*** as President Hathaway, the impulsive and rather dimwitted ***president of the United States***. Not wanting to be remembered as "the President in office when the world came to an end", he agrees with General Monger's "Monsters vs. Aliens" plan when the U.S. Military is unable to defeat the robot probe sent by Gallaxhar.
* Paul Rudd as Derek Dietl, a local weatherman and Susan's ex-fiancé. He jumps at whatever opportunity he has to boost his career, which causes him to place his job and himself before his relationship with Susan, canceling their plans to have a romantic ***honeymoon*** in Paris to land an ***anchorman***job in ***Fresno, California***.
* Jeffrey Tambor as Carl Murphy, Susan's overemotional father.
* Julie White as Wendy Murphy, Susan's loving mother.
* Renée Zellweger as Katie, a woman whose date with her boyfriend Cuthbert is interrupted by the landing of Gallaxhar's robot.
