- Arm Cannon: The Chibi-Blaster.
- Badass Adorable: He knows well how to use a blaster and kill spydorz. Not to mention he beat the Spydor Queen all by himself, despite his tiny size and limited functions. He is cute as a button.
- Cute Machines: They're not called Chibi-Robos for nothing.
- Cute Mute: Chibi-Robos apparently don't come with a voice chip, as the only way they can communicate is through a green exclamation point sign and red no sign that pops out of their heads.
- Green Thumb: The Blooming Chibi-Robo model from Park Patrol was built to plant flowers.
- Legacy Character: Because Chibi-Robos are mass-produced, no two games star the same Chibi-Robo.
- Robot Maid: Much smaller than most examples, but still able to get the job done.
- The Stoic: He rarely shows any emotion, not even when in danger. However, he will sometimes squint when angry or skeptical of something, and he does a little fist-pump when he gets one of Geotron X's questions right in Photo Finder.
- Talk to the Fist: Not really a fist, but when the Queen Spydor has the family captured, the living room flipped upside down, and him and Telly cornered, his response is to bring out the Chibi-Blaster and aim the business end right at her.
- Talking with Signs: He speaks with "yes" and "no" signs. Generally, he's mute.
- The Voiceless: He only talks through green and red signs as "yes" or "no". Photo Finder has a few dialogue trees that Chibi-Robo answers on his own, however.
Characters in the original game
- Casanova Wannabe: He claims that the girls are all over him and is convinced at a couple points that Mrs. Sanderson and Jenny are attracted to him.
- Cute Machines: As cute as the 'bot he accompanies.
- Cowardly Sidekick: He's quite chickenboned on occasion.
- Exposition Fairy: Explains game mechanics and clarifies goals.
- Mentor Archetype: While he was activated at the same time as Chibi-Robo was, he is his guide and mentor and knows more about their stuff than he does.
- Mr. Exposition: See Exposition Fairy.
- Robot Buddy: Built to serve as a helper to Chibi.
- Bumbling Dad: Oh, yes. He means well and clearly cares about his wife and daughter, but is too lazy, immature, and short-sighted to be a particularly good husband or dad.
- Bunny-Ears Lawyer: Who ever thought that Mr. Sanderson of all people would be the one who created the Spydorz?
- Gadgeteer Genius: He used to work as an engineer. He invented the Spydorz, and he shows he's still got it when he upgrades Chibi's blaster for a boss fight with the Queen Spydor.
- Large Ham: As demonstrated by his Skyward Scream the first time he sees Chibi in action. He's pretty exuberant.
- Lazy Bum: Unemployed, he spends most of his time watching cartoons, reading comic books, and snacking with little to no taking care of the house or looking for work. He starts to shape up a little when Mrs. Sanderson announces she's considering getting a divorce, taking on some chores and trying to cook for the rest of the house.
- Man Child: Excitable and a big fan of toys and cartoons. His habit of blowing money on his hobbies despite being unemployed has put a strain on his marriage.
- Nice Hat: Always wearing his blue cap.
- No Name Given: Always referred to as either "Mr. Sanderson" or "Dad".
- Ugly Guy, Hot Wife: An underdressed slob with scruffy hair and a fluffy mustache, married to the well-kept and pretty Mrs. Sanderson.

- Neat Freak: In contrast to her sloppy husband.
- No Name Given: Always referred to as either "Mrs. Sanderson" or "Mom".
- Only Sane Man: She's level-headed and frank, and, by the time the game starts, a bit tired of the wackiness of the rest of her household.
- Ugly Guy, Hot Wife: Pretty, made-up, classily-dressed, and married to the scruffy and goofy-looking Mr. Sanderson.
- Cloud Cuckoolander: Wears a frog hat, speaks in ribbits, and claims (through Sunshine) that an "evil frog wizard" cursed her to behave like a frog; however, it all seems to be in the spirit of childish play.
- Creepy Child / Heroic BSOD: After Mrs. Sanderson locks herself in her room, Jenny spends all night staring at her toy TV, which is displaying a bizarre symbol. The toys don't even bother pretending not to be alive while she's doing this.
- Nice Hat: She wears a frog wig on a daily basis.
- She Is All Grown Up: She reappears in ''Big Rich Happy Sweep" as a middle-aged woman.
- The Unintelligible: Unless Chibi-Robo is wearing the frog suit.
- Big Friendly Dog: Aside from what he did to Memphis, he's a nice dog. And even then, Memphis is willing to forgive him.

Space Hunter Drake Redcrest
- Cool Helmet: Gatchaman-style!
- Expy: Of Gatchaman and Buzz Lightyear.

- Large Ham: It's even said in the Space Hunter code that Space Hunters must greet everyone by yelling.
- Leitmotif: "Go! Space Hunter Drake Redcrest!"
- Miles Gloriosus: He's confident, dramatic, and boastful, but the one time we see him "in action" - up against a rampaging Sunshine - he's taken out by a child's teddy bear.
- The Bus Came Back: Reappears in Photo Finder as the host of a shooting gallery minigameAnd in Zip-Lash as one of the toys requesting snacks.
- Gag Lips: Her face is mostly lips and eyes.
- Leitmotif: "A Maiden's Thoughts".
- Love Letter: She writes one for Drake Redcrest. If the player finds it, they can either choose to give it to Drake or give it back to Sophie.
- Stalker with a Crush: She spends most of her nights following Drake Redcrest, hoping she can work up the courage to confess her crush to him. When she finally gives him a love letter in the conclusion of her subplot, she passes out (temporarily) dead from excitement, and her ghost will follow Drake around until she's revived.
The Free Rangers
- Ascended Extra: Tampa is just one of the soldiers in the crowd during the first game, but in Park Patrol he's the only Free Ranger to appear.
- Badass Boast: "You're Free Rangers! You're hard-boiled!"
- The Bus Came Back: A single Free Ranger (specifically, Tampa) reappears in Park Patrol. Sarge and two other Free Rangers also reappear in Happy Big Rich Sweep.
- Drill Sergeant Nasty: Sarge.
- Jerk with a Heart of Gold: Again, Sarge.
- Leitmotif: "Once Again It's the Drill Sergeant For Us Today".
- Punny Name: The group's name is a play on "free-range eggs," or eggs laid by chickens that are allowed to roam free.
- Screw This, I'm Outta Here!: Some of the rangers later ditch the army and get new jobs.
- Theme Naming: Except for Sarge, all of them are named after American cities.
- Badass Beard: Befitting a toy pirate captain.
- Jerk with a Heart of Gold: He is really attached to Giga-Robo and worships him wholeheartedly. Understandably, since he is the one who made all the toys alive in the first place.
- The Pirates Who Don't Do Anything: [[spoiler; He couldn't bring himself to steal from the Sandersons when he saw how poor they had become, so he renounced his piracy.]] Averted later when he learns that the Sandersons have recovered financially.
The Great Peekoe
- Badass Mustache: Long and curling.
- Con Man: He claims to be a guru and has people gamble in an obviously-rigged game against him as a "cleansing ritual".
- Scam Religion: He claims that people's souls are cleaned when they get rid of their Moolah, but he really is just saying this because he wants money for himself.
- Bears Are Bad News: He's pretty nice (albeit kind of creepy) when he's not suffering from withdrawal, but otherwise he fits.
- Fantastic Drug: He has a heroin-esque addiction to flower nectar.
- Hidden Depths: When he's not craving nectar, he proves to be wiser and more mature than most of the other toys.
- Leitmotif: Sunshine has two: "So dododo" for his regular personality, and "Honeyholic" for his crazy personality.
- Mood-Swinger: Can go from sweet and cute, to crazy and violent if he doesn't get his nectar.
- My God, What Have I Done?: After Mort..."scares him off", he can be seen sulking in the corner of Jenny's room, thinking about overcoming his addiction.
- Nightmare Face: When he's having a craving, his face changes from a cute, button-eyed teddy bear face to a red-eyed roaring face.
- No Indoor Voice: When in "withdrawal mode," he's almost always shouting. His Simlish even changes from a "baby talk" voice to a "shouting middle-aged Japanese man" voice.
- Trademark Favorite Food: NECTAR!
- All Love Is Unrequited: She has a major thing for Funky Phil. Nothing ever comes of it, apart from it presumably contributing to her temporary Heroic BSOD over Phil's "death".
- Built With LEGO: Yup! Comes into practical play near the resolution of her and Funky Phil's subplot.
- Cannot Tell a Joke: She fancies herself funny. However, most attempts by her to joke are to oversell Incredibly Lame Puns.
- Cool Old Lady: Friendly, supportive, and spunky, if a little high-strung. You wouldn't guess she was an old lady if she didn't refer to herself as such.
- Deep South: Has a Southern accent and a penchant for Southern- and Wild West-themed metaphors and similes.
- Everything's Better with Dinosaurs: A LEGO T-rex.
- Leitmotif: "I'ma Gonna Do Somethin'"

- Sentient Vehicle: After she jumps from the loft in her subplot, she's temporarily rebuilt into a truck by Mr. Sanderson.
- Disco Dan: All about disco dancing.
- Keet: Chatty, outgoing, and high-spirited. The only time you see his groove thrown off is when he's flustered on being introduced to his first batch of kids.
- Leitmotif: "Funkmaster Flower Train".
- The Klutz: As a dancer, Freaky Phil is apparently not all that well-coordinated with the rest of his family. And let's just say an instance of him tripping and falling causes one epic misunderstanding.
- The Runt at the End: They're all identical with their dad's pink and yellow color scheme... except for the last one of them to sprout, the clumsy, unintelligible, red-and-blue Freaky Phil.
- The Unintelligible: Freaky Phil's dialogue is written almost entirely as "gebahbah" noises and accompanied by a harsh, sharp-yet-fuzzy Voice Grunting noise.
- Babies Ever After: After his subplot with Pitts is completed, if you visit the couple, you'll find they've gotten married and had two kids.
- Face of a Thug: He's a sweet if glum guy, and laments that his ugly appearance scares people away from him.
- Leitmotif: "Timid Love".
- Mummy: An action figure memento from a film about a mummy that the Sandersons saw on their first date, apparently.
- Nice Guy: Soft-spoken, well-meaning, and gentle.
- Ugly Guy, Hot Wife: You never expected a pretty princess to be attracted to an ugly mummy.
- Babies Ever After: She marries and has two kids with Mort after their subplot is resolved.
- Expy: Of Princess Peach.
- Ugly Guy, Hot Wife: You never expected a pretty princess to be attracted to an ugly mummy.
- Jerk Ass: Irritable and... feisty, to say the least.
- Big Good: Remembered fondly by all of the household toys, and is a central figure in the game's main plot.
- Gentle Giant: Every bit as helpful as his smaller counterpart.
- Posthumous Character: That is, until Chibi-Robo is able to revive him.
- The Voiceless: Like Chibi-Robo, he can't speak.
Titan, Io, Ganymede, and Little Bang
- Aliens Speaking English: Their language is regular English, just spoken very quietly.
- Bizarre Alien Biology: They all look like squashed and stretched-out versions of Chibi-Robo.
- Heroic BSOD: After seeing the deactivated Giga-Robo, the aliens become sick to the point where they can't move.
- Innocent Aliens: It takes them a little while to come to terms with the fact that Giga-Robo is "dead".
Characters in Park Patrol
- Exposition Fairy
- Genki Guy: He sometimes gets so enthusiastic about helping Chibi-Robo that he worries he'll short-circuit.
- Mission Control: He communicates with Chibi-Robo via a satellite dish, alerting him when something important has happened in the park.
Sergeant Smogglor AKA General Greenthumb
- The Dragon: To Miasmo.
- Frickin' Laser Beams: His "ZAPPOW" attack, which can sap the life out of living toys. Fortunately, it has no effect on Chibi-Robo.
- Good Costume Switch: When he returns to his "General Greenthumb" persona, he loses the black-and-white coloring in favor of bright shades of blue and green.
- As Long as There Is Evil: Gives a speech akin to this after being defeated.
- Big Bad: Of Park Patrol.
- Eldritch Abomination: Whenever he appears in the park, the sky gets clouded in smog and the city in the background inexplicably becomes a bunch of factories.
- Fog of Doom
- Giggling Villain: His only voice clip is a wheezy high-pitched cackle.
- Knight of Cerebus
- Monster Clown: His face resembles warped clown makeup.
- Vader Breath: His Simlish is nothing more than an evil laugh, but his dialogue is regularly interrupted by coughs and wheezes.
- Walking Wasteland
- Gratuitous French: "Bonjour, tres bien, et merci!"
- Maurice Chevalier Accent
- Trademark Favorite Food: Candy canes, most likely because of the cane he's holding.
- Casanova Wannabe: He tries twice to put the moves on Chassy, both times being unsuccessful.
- Jive Turkey
- Trademark Favorite Food: Burgers, even though they're bigger than his entire body.
Pop and Fizz
- Everything's Better with Penguins
- Product Placement: In-universe example. They're mascots for Pop Fizz Soda, which is also their Trademark Favorite Food.
- Totally Radical
- Verbal Tic: They have a tendency to drop the words "pop," "bubbly," and "fizz" in their dialogue.
- Catchphrase: "They haven't retired my number yet, you know!"
- Deliberately Monochrome: You can restore his color if you cheer him up, however.
- Trademark Favorite Food: Chewing gum.

Super Geotron X
Ketschburg and Mostardin

- French Cuisine Is Haughty
- Nonstandard Character Design: Unlike most of the other characters, these two are more appliances than they are toys.
- Cowardly Lion
- Nonstandard Character Design: Even moreso than other examples, since he's supposed to be a statue.
