Free Monsters vs Aliens Coloring Pages: 40+ printable PDF pages spanning a monster team where every member’s transformation went in a completely different direction. A fifty-foot human, a shapeless gelatin creature, and a building-sized larva all share the same roster, but none of them share a coloring approach. All free, download PDF to print, or color online.
Every monster in this cast began as something ordinary, human or insect-sized, before a scientific accident sent their transformation in a completely different direction. Susan kept her human shape but grew to fifty feet tall with pale blue-white skin. B.O.B. lost his shape entirely, becoming a translucent blue gelatin mass with no bones or fixed form at all. Dr. Cockroach fused with an insect, and Insectosaurus grew from a tiny larva into something the size of a building. Coloring this set means recognizing that each character represents a genuinely different transformation category, not a variation on the same monster theme.
The pages are divided into two types. Solo and duo monster pages reward identifying which specific type of transformation each character represents before choosing a palette, since a shapeless gelatin creature and a giant-scale human require entirely different coloring approaches. Group, battle, and human-cast pages ask you to hold five very different monster designs together in one coherent scene. The simpler solo pages suit younger fans; the detailed battle and group compositions give older fans more to work through.
These pages work well at home or as fan art. These are fan-made coloring pages and are not official, licensed, or endorsed by DreamWorks Animation or any rights holder of Monsters vs Aliens.

What’s Inside Monsters vs Aliens Coloring Pages
Susan Murphy and Ginormica Pages
Susan appears across the largest share of solo pages, alongside compositions with B.O.B., Dr. Cockroach, The Missing Link, and a duo page with her former fiancé.
Coloring Susan: her transformation kept her human proportions intact while increasing her scale dramatically, which means her design should stay recognizably human in shape even though her skin shifts to a pale, cool blue-white from the experiment that changed her. Her hair turns a stark white, in contrast to her earlier brown. Keep her clothing in the simple, practical tones of someone unprepared for sudden transformation, since her story is about an ordinary person adjusting to an extraordinary new scale rather than a creature designed to look alien from the start.
B.O.B. Pages
B.O.B. appears in solo pages and in several group compositions with the other monsters and the giant robot.
Coloring B.O.B.: he is the most structurally unusual character in the entire cast, a blob of blue gelatin with no bones, no fixed shape, and only minimal facial features. Color him as a translucent, jelly-like blue rather than a flat opaque fill: apply the color with a slightly lighter tone where his form would catch light, suggesting a soft, wobbling surface rather than solid material. Since he has no consistent silhouette from page to page, focus on getting the translucent quality of the color right rather than worrying about matching any specific shape across different compositions.
Dr. Cockroach Pages
Dr. Cockroach appears in solo pages, in a bartender-themed page, and in several group compositions with B.O.B. and The Missing Link.
Coloring Dr. Cockroach: his transformation fused him with an insect, which shows in his reddish-brown, slightly glossy skin tone reminiscent of a cockroach’s shell, along with small antennae. He retains a human torso and wears a lab coat, a visual reminder of his scientific background before the accident. Keep the insect-toned reddish-brown consistent across his exposed skin while letting his white lab coat provide a clean, neutral contrast against it.
The Missing Link Pages
The Missing Link appears in solo pages and group compositions with Susan, Dr. Cockroach, and B.O.B.
Coloring The Missing Link: his amphibious transformation gives him fish-like, scaled skin in cool blue-green tones, distinct from both Susan’s pale human-derived blue and Dr. Cockroach’s warm reddish-brown insect tone. His muscular build and self-assured posture suit a slightly deeper, more saturated version of his scale color than a paler, more tentative rendering would.
Insectosaurus Pages
Insectosaurus appears in several pages, including compositions with Susan and a page showing him under attack.
Coloring Insectosaurus: as a building-sized insect larva, his coloring should stay in the warm yellow-orange range typical of grub or larva coloring in nature, scaled up to enormous size. His sheer scale relative to every other character in the set is the main visual feature his page needs to communicate, so keeping his warm tone bright and consistent helps him read clearly even in compositions where he dwarfs the human-scale figures around him.
Gallaxhar and Robot Pages
Gallaxhar, the alien antagonist, appears in two pages, including an angry expression variant. The giant robot he commands appears across several solo and group pages.
Coloring Gallaxhar and the robot: Gallaxhar’s design uses a cool, alien green skin tone with a sleek, non-human head shape that should stay distinct from any of the five monsters’ transformation-derived colors, reinforcing that he comes from an entirely separate origin. The giant robot suits a metallic grey-and-silver palette with darker panel lines, giving it a cold, mechanical presence that contrasts with the organic monster designs it faces in battle.
President Hathaway and General Monger Pages
President Hathaway and General Monger or General Warren appear together in a small number of pages, representing the human government’s response to the monster and alien threats.
Coloring the human cast: these characters use ordinary human skin tones and formal government attire, providing a grounded visual baseline against which all five monster transformations and Gallaxhar’s alien design read as more dramatic by comparison.
Printable PDF and Online Monsters vs Aliens Coloring Pages
Every design comes in two ways: a printable PDF for paper, or the same artwork colored on screen.
Using both formats: print the PDF when you want a clean sheet for markers or colored pencils suited to varied textures, and use the on-screen version when there is no printer nearby. The PDF holds each monster’s distinctive transformation design cleanly on standard letter or A4 paper.
What These Pages Do
Most monster-team coloring sets ask you to render variations on a single creature concept. This cast started ordinary, then transformed in five genuinely unrelated directions: Susan kept her shape at a giant scale, B.O.B. lost his shape entirely, Dr. Cockroach fused with an insect, The Missing Link turned aquatic, and Insectosaurus grew enormous. Working through this set builds the skill of recognizing transformation categories before choosing any color, since these characters require entirely different coloring logic, despite all being technically monsters. B.O.B. in particular asks for a rare technique: rendering translucency on a character with no fixed silhouette. That combination, sorting subjects by category rather than surface similarity, applies to character design across a roster and any project where similar-looking subjects actually demand different approaches. From here, Cartoons coloring pages is the parent hub, and Megamind coloring pages offers the closest DreamWorks tonal parallel.
The American Art Therapy Association recognizes that creative engagement with themes of transformation and difference, particularly where characters who once felt alien to themselves find belonging within a found community, offers meaningful material for processing identity and acceptance. The monster team’s central arc, learning to see their transformations as a source of strength rather than isolation, gives the coloring pages an emotional layer beneath the technical challenge of rendering five very different creature designs. The American Academy of Pediatrics supports creative activities that help older children and teens engage with themes of difference, unexpected change, and finding acceptance within a group. This ensemble cast provides a comedic, accessible entry point for that kind of reflection.
How to Color Monsters vs Aliens Coloring Pages
These steps work for any page in the set, from a solo monster portrait to the full battle scenes.
Identify each character’s transformation category before choosing a palette: giant-scale human, shapeless gelatin, species hybrid, amphibious mutation, larval growth. Recognizing which category a character belongs to determines whether you’re rendering a recognizable human shape, a translucent surface, or a creature with no precedent in the rest of the cast.
On B.O.B. pages, prioritize translucency over shape consistency. Since he has no fixed silhouette, focus on applying his blue gelatin coloring with a slightly lighter highlight where his form would catch light, suggesting a soft, jelly-like material rather than worrying about matching his exact shape to other pages.
Keep Susan’s human proportions intact even as you apply her transformed skin tone. Her design depends on staying recognizably human in shape, just at fifty times the normal scale, with pale blue-white skin and stark white hair marking the change.
On group pages, separate each monster’s color family clearly. Susan’s pale blue, Dr. Cockroach’s reddish-brown, The Missing Link’s blue-green scales, and Insectosaurus’s warm yellow-orange. Keeping these distinct prevents the group from blending into a single muddy mass of similar tones.
Use cool metallic grey for the robot and cool alien green for Gallaxhar to separate them from the organic monster cast. Both come from outside the monster team’s origin story, so their palettes should read as clearly distinct from any of the five transformation-derived colors.
5 Creative Craft Ideas with Monsters vs Aliens Coloring Pages
Transformation Category Lineup
Color one page each for Susan, B.O.B., Dr. Cockroach, and Insectosaurus, then cut each character out roughly along its outline.
Arrange the four cutouts in a row on a backing sheet with a small handwritten label under each describing their transformation type: giant scale, shapeless, hybrid, larval growth. Takes about thirty minutes.
B.O.B. Wobble Puppet
Color a B.O.B. page, then cut it out and glue it onto a small paper spring made by folding a strip of paper back and forth accordion-style.
Attach the spring to a small base so B.O.B. wobbles when gently pushed, mimicking his shapeless, jiggling movement in the film. Takes about twenty minutes.
Monster Team Versus Robot Diorama
Color the giant robot page and two or three monster pages, then cut each figure out and attach small folded paper tabs to the back of each.
Stand all the cutouts up on a flat surface using the tabs to create a simple tabletop battle scene you can rearrange. Takes about twenty-five minutes.
Susan Scale Comparison Card
Color a Susan solo page at full size, then color a small human-sized figure on a separate tiny scrap of paper.
Place the tiny figure next to the colored Susan page to visually demonstrate her fifty-foot transformation in scale, even on paper. Takes about ten minutes.
Gallaxhar Threat Meter Dial
Color the Angry Gallaxhar page and the Happy or neutral Gallaxhar page on two small circles of cardstock.
Layer the two circles with a paper fastener at the center so one can rotate to reveal either expression through a small cut window in the top layer, creating a simple spinning mood dial for the character. Takes about twenty minutes.
FAQ About Monsters vs Aliens Coloring Pages
Are these Monsters vs Aliens coloring pages free, and can I color them online?
Yes. Every page is free, with no sign-in or payment required. Download the PDF to print at home, or color directly on screen in the browser.
Does the set include the human cast, like President Hathaway, or mainly the five monsters?
The set is built mainly around the five monsters, Susan, B.O.B., Dr. Cockroach, The Missing Link, and Insectosaurus, who appear across the vast majority of pages. President Hathaway and General Monger appear in a smaller number of pages, representing the human government’s response to events in the story.
What is Monsters vs Aliens?
Monsters vs Aliens is a 2009 animated film produced by DreamWorks Animation. It follows a group of monsters, each created by a different scientific accident, who the government recruits to defend Earth against an alien invasion led by Gallaxhar. The film is known for its ensemble monster cast and its blend of science fiction parody and found-family themes. You can read more about the film on Wikipedia.
Why are all five monsters such different shapes and colors from each other?
Each monster resulted from a completely different type of scientific transformation: Susan grew to giant scale while keeping her human shape, B.O.B. lost his shape entirely and became a gelatin mass, Dr. Cockroach fused with an insect, The Missing Link became amphibious, and Insectosaurus grew from a tiny larva into something building-sized. The film treats these as five genuinely distinct categories of transformation rather than variations on one monster concept, which is why their designs share almost nothing in common.
What colors should I use for Susan or Ginormica?
Pale, cool blue-white skin and stark white hair, set against otherwise ordinary human proportions and simple, practical clothing. Her design depends on staying recognizably human in shape despite the dramatic change in scale and skin tone.
How do I color B.O.B. if he doesn’t have a fixed shape?
Apply his blue gelatin coloring as a translucent rather than flat opaque fill, with a slightly lighter tone where his form would catch light to suggest a soft, jelly-like surface. Since his silhouette changes from page to page, focus on the quality of the translucent color rather than matching an exact shape across different compositions.
Are these official Monsters vs Aliens coloring pages?
No. They are fan-made coloring sheets for personal use and are not affiliated with, licensed by, or endorsed by DreamWorks Animation or any rights holder of Monsters vs Aliens.
What colors should I use for Insectosaurus?
A warm yellow-orange typical of grub or larva coloring in nature, scaled up to enormous size. Keeping this warm tone bright and consistent helps him read clearly even in group compositions where his massive scale dwarfs the other characters around him.
