    Susan Murphy/Ginormica
Voiced by: Reese Witherspoon (Film and video game), Riki Lindhome (TV series)

Susan Murphy (her monster nickname being "Ginormica") is a normal woman who is hit by a radioactive meteor on her wedding day, causing her to mutate and grow to a height of 49 feet 11 inches (15.21 m). Meek and unassertive, she just wants to return to her old life, but gradually warms up to her new status as a monster. In addition to her size, she is amazingly strong and has a resistance to energy attacks.

  • Action Girl: Grows into one. She took down a robot and fought Gallaxhar.
  • Attack of the 50-Foot Whatever: Susan is 49-feet-11-inches tall.
  • Badass Adorable: She's a kind and dorky young woman who, over the course of the movie, manages to take down a giant robot and eventually stop an alien invasion.
  • Beware the Nice Ones: Susan is quite sweet and loyal to her companions. However, as the movie progresses, she becomes more assertive when facing aliens. Right at the end, she also breaks up with Derek on live TV once he started acting like a self-absorbed ladder climber who blamed her for her mutation.
  • Break the Cutie: She starts off happy with her life, only to lose it all on her wedding day to something out of her control, ends up scared and alone in a place she doesn't know and unable to call anyone, and finds out the man of her dreams doesn't actually care for her. Things do eventually perk up for her, but still.
  • Brought Down to Badass: Despite losing her quantonium during the climax of the movie, she takes enough levels in badass to skate her way to the control deck and take on Gallaxhar himself, despite him being larger than her by that point and wielding a laser gun.
  • Brought Down to Normal: She loses her size and strength during the third act of the movie, courtesy of Gallaxhar draining the quantonium from her body.
  • Butt-Monkey: In the TV series, she suffers occasional moments of slapstick. Her most embarrassing incident was getting shot in the butt with pickles while the whole thing was posted on the internet.
  • The Chick: The token female of the group as well as the main character.
  • Costume Evolution: Susan switches her black jumpsuit out for a blue jumpsuit and puts her hair up into a ponytail for the animated series.
  • Cute Giant: Susan may be giant, but she's still an adorable woman.
  • Cute Monster Girl: She may be a giant, but she's still an attractive young woman.
  • Dark-Skinned Blonde: Justified by the Magic Meteor that gave her powers shifting her hair from brown to white.
  • Deconstruction: Susan is the stereotypical modern woman. About to get married, normal everyday name, loving parents, middle class lifestyle. Most of that goes out the window following her mutation, and the rest of the movie is based around her picking up the pieces. It becomes a Reconstruction, however, after she ultimately becomes a stronger person for it.
  • Desperate Plea for Home: Shortly after Susan/Ginormica is captured by the US government, she awakens to find herself in a secret facility that houses other monsters such as herself, and is given a brief tour of the facility by General Warmonger, where she's duly informed she'll basically be living there for the rest of her life. Naturally, given that she's only been a giantess for all of a day and a half - and that's only because a meteor full of Quantonium fell on her just minutes before she was going to be married - she's incredibly upset at this and begs Warmonger to let her go home.
  • Does Not Know Her Own Strength: She doesn't know how to control her strength for most of the movie, destroying a helicopter early on and subjecting Derek to bone-crushing hugs and near-neck-snapping kisses. She gains more control over her strength during the 2013 series, showcasing her Character Development.
  • Expy: Evidently a more light-hearted take on Nancy Archer, the titular character in Attack of the 50-Foot Woman. Poor woman with a slimeball husband who gets turned into a giantess by alien technology, but Nancy Archer is more of a Tragic Monster while Susan is just straight-up The Heroine.
  • Gentle Giant: She's 49 feet and 11 inches, and she's very nice.
  • Giant Woman: Due to a meteor falling on her.
  • The Heroine: The movie revolves around Susan embracing her monster status.
  • I Just Want to Be Normal: For most of the movie, she mostly wants to return to her original size, leave the facility and get back to her normal life. She eventually grows to enjoy her new form, however.
  • Innocent Blue Eyes: Which represents her kindness and naivety.
  • The Leader: Of Team Monster in the series.
  • Locked into Strangeness: Her hair was originally brown but after getting hit by a Magic Meteor her hair turns white. When Gallaxhar temporarily shrinks her back to normal size in the film, her hair stays white.
  • Magic Pants: In the series, her jumpsuit shrinks and grows with her when she changes size. Also, in the movie, her wedding dress manages to stay on her body in spite of ripping in some places.
  • Meaningful Name: Her last name is Murphy. Considering how much goes wrong for her, it's extremely appropriate.
  • Mystical White Hair: As a result of getting hit by a Magic Meteor.
  • Nice Girl: Susan is a kind and caring woman.
  • Only One Who Likes Spam: In the cartoon, she's the only one who likes Turkey Tetrazzini, whereas everyone else, even B.O.B., thinks it's too disgusting to look at, let alone eat.
  • Picked Last: She had been picked last for dodge ball a lot when she was younger; training dummies were even picked before her.
  • Power Dyes Your Hair: Susan's hair turned white after the quantonium she absorbed turned her into a giant. Notably, she retains the white hair even after having the quantonium (temporarily) taken from her body.
  • Power Glows: Her skin glows green as she is about to grow; her fiance literally says this to her.
  • Sensual Spandex: Dons a black, skin-tight spandex suit upon being abducted by Gallaxhar.
  • Single Woman Seeks Good Man: Susan was in love with Derek, when she thought he was a devoted and loving man. However, she ended up crushed when his true personality showed, and promptly got her revenge.
  • Sizeshifter: In the series, Susan gains the ability to go from monster-size huge to normal human size at will by thinking certain thoughts.
  • Strong Family Resemblance: To her mother, especially before her transformation — Susan is basically a younger version of her mother.
  • Super Strength: One of the advantages of being a 49ft 11in giant imbued with quantonium/hyperion energy is strength enough to easily smash through stone, steel, alien metals, and even energy barriers.
  • Took a Level in Badass: Susan learns to embrace herself as a "monster", going from a scared girl to a powerful monster who manages to take down a giant alien robot by herself, and later defeats the alien who sent it after being Brought Down to Normal.
  • Trademark Favorite Food: Turkey Tetrazzini.
  • Tron Lines: These appear on her jumpsuit when she changes her size in the series.
    Dr. Cockroach Ph.D
Voiced by: Hugh Laurie (Film and Mutant Pumpkins from Outer Space), James Horan (Video game and Night of the Living Carrots), Chris O'Dowd (TV series)

Dr. Herbert Cockroach Ph.D (sometimes referred to by the others as Doc) is a brilliant but mad scientist who, in an experiment to imbue himself with the abilities of a cockroach, ending up with a giant cockroach's head and some cockroach personality, but gained the ability to climb up walls and high resistance to physical damage.

    The Missing Link a.k.a. Link
Voiced by: Will Arnett (Film, video game, and Mutant Pumpkins from Outer Space), David Kaye (Night of the Living Carrots), Diedrich Bader (TV series)

The Missing Link is a 20,000-year-old fish-ape hybrid who was found frozen and thawed out, only to escape and wreak havoc at his old lagoon habitat. Usually referred to as Link, he behaves as a macho jock most of the time, but is out of shape.


B.O.B. (Benzoate Ostylezene Bicarbonate) is an indestructible gelatinous mass created when a genetically-altered tomato was injected with a chemically-altered ranch dessert topping, the resulting goo gaining some form of consciousness.

  • All-Loving Hero: He very rarely hates anyone. Derek becomes a big exception after he heard from Susan how Derek is a selfish jerk.
  • Big Fun: He's a big, blob monster but a very happy-go-lucky one.
  • Blob Monster: As literal as the trope can get, given he's a Captain Ersatz of the Trope Namer.
  • Blue Is Heroic: A blue monster who happens to be one of the heroes.
  • Breakout Character: As a result of his Kid Appeal, B.O.B. quickly eclipsed the other monsters to become the most popular character of the movie, leading to his greater prominence in the series. He's also the most likely to appear in DreamWorks-related crossovers as a result.
  • Captain Ersatz: Of The Blob.
  • Cloudcuckoolander: He lacks a brain, and it shows.
  • Cyclops: Only has one eye.
  • The Ditz: Parodied to its logical extreme. Because he's an amorphous blob, he quite literally has no brain.
    B.O.B.: Turns out, you don't need one!
  • Extreme Omnivore: This guy will eat anything. ANYTHING. Then again, given who he's a parody of this isn't a surprise.
  • Fun Personified: Very happy-go-lucky and is quite playful when loving to play tons of games (whether they're eccentric or not), the movie and the short "B.O.B.'s Big Break" enhanced this trope.
  • Fun with Acronyms: His name stands for Bensoate Ostylezene Bicarbonate.
  • Hilariously Abusive Childhood: When B.O.B. was a child, Monger force-fed him nothing but carrot puree for years on end, resulting in him developing a fear of carrots in Night of the Living Carrots.
  • Ink-Suit Actor: He has Seth Rogen's eye, mouth shape, and signature laugh.
  • Keet: Is eternally happy and upbeat with just about everything.
  • Kid-Appeal Character: This explains his prominence in the TV series.
  • Kindhearted Simpleton: He's very dimwitted and clueless, but very kind, well-meaning and friendly.
  • Plucky Comic Relief: B.O.B. often provides the main source of humor whenever he's on-screen due to his goofy Cloudcuckoolander tendencies.
  • Rubber Man: Being an indestructible blob, he can absorb any physical attack and bounce it right back. In the movie, at least.
  • Spanner in the Works: Blew the other monsters' escape attempt by thinking a government plane was a piñata and usually screws up Dr. Cockroach's plans by his stupidity.
  • Spotlight-Stealing Squad: Gets a ridiculous amount of time devoted to his random antics in the 2013 series, to the point where he might as well be the main character instead of Susan.
  • Too Dumb to Live: He once forgot how to breathe.
Voiced by: Conrad Vernon

Insectosaurus (nicknamed "Insecto") was formerly a 1-inch (25 mm) grub transformed by nuclear radiation into a 350 foot (110 m) monster with the ability to shoot silk out of her nose, referencing that she is a silkworm. She is best friends with Link, who mistakenly believed that Insectosaurus was male... until she transformed into a butterfly with feminine characteristics at the end of the film. The book The Art of Monsters vs. Aliens confirms that Insectosaurus is indeed female.

    General W.R. Monger
Voiced by: Kiefer Sutherland (Film), Fred Tatasciore (Video game), Kevin Michael Richardson (TV series)

General Warren R. Monger is 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.

  • Big Good: He occupies this role, although it is limited to capturing the monsters and then directing them to the threat.
  • Cool Old Guy: In the film he states that he's been the monsters' warden "for 50 years".
  • Expy: Of General Jack D. Ripper, Sterling Hayden's character in Dr. Strangelove.
  • Four-Star Badass: Has no problem taking to the field when he has to.
  • General Ripper: Implied with his name, but it turns out to be a subversion — he's shocked when the President accidentally launches a nuclear strike.
  • Ironic Name: Despite his name being a pun on "Warmonger", Monger actually tries to prevent wars in any way he can and stops the President from going for the Nuclear Option.
  • Jetpack: He often uses this as transportation.
  • Older Than He Looks: He looks good for 90.
  • Punny Name: A play on "Warmonger".
  • Reasonable Authority Figure: Even though he captured and imprisoned the monsters, he shows a great respect for them. In unused footage he was not pleased to hear that the president planned to take back his offer for the monster's freedom to save face.
  • Schoolyard Bully All Grown Up: Implied when he wedgies the 'nerd' at the conference who objects to his Monsters vs. Alien plan.
    The Invisible Man 
Mentioned in the film and had a brief cameo in "B.O.B.'s Big Break". He supposedly died before the events of the first film.
  • Deadpan Snarker: He loves making jabs at his friends, notably saying that Dr. Cockroach loves digging around in garbage.
  • Invisibility: Well duh. He is called the Invisible Man for a reason.
  • Pantomime: One of his favorite games to play is charades, where he often makes jabs at the people he's playing as.
  • Posthumous Character: Died before the movie, in 1984.
    President Hathaway
Voiced by: Stephen Colbert (Film), James Patrick Stuart (TV series)

President Hathaway is the impulsive and dimwitted President of the United States.

  • Bring My Brown Pants: "Boys, set the terror level to 'code brown', 'cause I need to change my pants!"
  • Dude, Where's My Respect?: In one episode in the animated series, he felt that no one listens to him even though he is the president.note 
  • Everyone Calls Him "Barkeep": He is often called by his title.
  • Ink-Suit Actor: His facial features resemble Stephen Colbert, and his personality is inspired by Colbert's character on The Colbert Report.
  • Manchild: He's stupid and immature.
  • No-Respect Guy: Particularly odd seeing as he's, well the president. However in the series, he's desperate enough for the respect that his office should afford him to explicitly ask Dr. Cockroach to "make people do what I say".
  • Our Presidents Are Different: He aspires toward President Action, but in reality he's closer to President Buffoon.
Voiced by: Rainn Wilson

Gallaxhar is an evil alien overlord who hopes to take over Earth and serves as the main antagonist of the film.

  • Adaptational Badass: His video game counterpart is portrayed as having more control of the situation and also puts up way more of a fight in the final confrontation.
  • Big Bad: Of the movie.
  • Evil Gloating: He's got Chronic Monologue Disorder something fierce!
  • Evil Overlord: He may be a funny character, but he's also a legitimate threat. He did destroy his homeworld, after all.
  • Extra Eyes: Shown to have four eyes placed single-file on his head.
  • Faux Affably Evil: He's polite but he still has no problem with committing genocide.
  • Genocide from the Inside: He mentions that he wiped out his entire planet.
  • Jerkass: Gallaxhar isn't nice by any means.
  • Laughably Evil: Despite his genocidal tendencies, Gallaxhar still has plenty of comedic moments, such as scalding his ear with hot tea and being unable to decide on a name for his planet.
  • Origin Story: He tells it to Susan as he's being cloned, but the cloning process keeps interrupting him (in a comic use of Plot-Based Voice Cancellation), so she (and we) only hear parts of it.
  • Where I Was Born and Razed: Gallaxhar destroyed his home planet and everyone in it for no explicit reason beyond being For the Evulz.
    Derek Dietl
Voiced by: Paul Rudd (Film), Nolan North (TV series)

Derek Dietl is a local weatherman and Susan's ex-fiancé.

  • Alliterative Name: Derek Dietl.
  • Disposable Fiancé: Derek turns out to be, in Susan's words, a selfish jerk. His wedding day attempt to convince her that his job interview in Fresno is an acceptable substitute (rather than an unfortunate delay) for the planned Parisian honeymoon pushes him into the Evil All Along category.
  • Hate Sink: While Gallaxhar may be the main threat of the movie, he at least has Laughably Evil qualities. Derek on the other hand is much more hateable, being an utterly selfish jerkass who only cares about becoming famous and was perfectly willing to break up with his loving girlfriend out of fear that she would upstage him.
  • Humiliation Conga: Suffers a major one at the hands of his former fiancée Susan by the end of the movie: not only does Susan see right through his fake apology and call him out, but he ends up launched though the air, swallowed by B.O.B., spat out onto the pavement, and given a "Reason You Suck" Speech by the blob, who then rejects him for a plate of jello. And all of it was caught on national television to boot!
  • It's All About Me: Derek doesn't care about Susan at all, only about his career.
  • Jerkass: Breaks off his engagement with Susan when she turned into a giant. She realizes he cares more about his career than her, and is angry that it only took becoming a giant to realize that.
  • Jerk with a Heart of Jerk: One reason he tries to reconcile with Susan at the end of the film is that he can get a network job in New York City if he gets an exclusive interview with her.
  • Married to the Job: The reason Susan breaks up with him is that all he really cares about is becoming a famous weatherman. Indeed, even before she became a monster, he moved their honeymoon from Paris to Fresno so he could attend a job interview.
  • Narcissist: Everything has to center around himself, everything else came second. When his concerned fiancée Susan came to him for help, his only concern was that she would embarrass him and ruin his career for being a monster.
  • Small Name, Big Ego: His name is small but he carries am extremely huge ego when it comes to reporting news and drawing attention to himself.
    Carl and Wendy Murphy
Carl Murphy
Wendy Murphy
Voiced by: Jeffrey Tambor and Julie White.

  • Generation Xerox: Susan looks like an identical younger version of her mother Wendy.
  • Open-Minded Parent: Unlike the other humans who are terrified of Susan in her super-form, they aren't terrified of her when they reunited with and tell her they still love her no matter what.
    Ms. Ronson 
Voiced by: Latifa Ouaou

  • Expy: Of Dana Scully
  • Screaming Woman: She's terrified of footage of the first four monsters and she screams in terror when General Monger says the monster's name. Thankfully, the General manages someone to get her out of the war room and the President screams an identical one when he says Ginormica's name.
  • What Happened to the Mouse?: She only appears in one scene screaming at the first four monsters and she had no dialogue (unless you probably count one or more deleted scenes with her).

Introduced in the TV series

Voiced by: Jeff Bennett

  • Bad Liar: So bad at lying that even B.O.B. isn't fooled by it.

  • Cool Chair: Has a hover chair to compensate for Earth's gravity. It also contain a variety of weapons.

  • Mind over Matter: Possesses powerful telekinesis.

  • Smug Snake
  • Token Evil Teammate: The only member of Team Alien with a truly malicious agenda.
Voiced by: Haley Tju

Sqweep is an adorable, intelligent alien child who has come to Earth because she needs to write a report on Earth's dominant species for school. She's rarely referred to with pronouns, but Monger calls her "Miss Sqweep" and B.O.B. calls her a "she" at the beginning of the episode "Number Seven!".

  • Bizarre Alien Biology: Sqweep's species have a dangerous type of body waste disposal called Number 7 and need a special toilet to handle it.

Voiced by: Gillian Jacobs

Sta'abi is a hotheaded female alien from a warrior/hunting culture.

  • Alien Lunch: Sucks down small, tentacled alien creatures whole and alive, because eating cooked food is for Puny Earthlings. A mighty warrior such as herself requires a "live protein diet".
    Susan: You mean high protein?
    Link: (nervously eyeing a pile of the squirming creatures) I don't think she does...
  • Aliens of London: Sports a thick Russian accent.
  • Green-Skinned Space Babe: Well, she has yellow skin. Still a hottie.
  • Hartman Hips: Despite being an alien, she sports a curvaceous figure.
