History Characters / ReadyJetGoEarthies

* BreakoutCharacter: He proved popular with fans, and is so {{Troperrific}} that he got his own page. To put in perspective, Mitchell is a recurring character, and Jet, the protagonist, doesn't have a page because it doesn't meet the 40k byte limit for CharacterSpecificPages.

* SmartDumbAndInBetween: The Smart to Lillian's Dumb and Mindy's In Between. Mitchell is incredibly intellectual and [[AdorablyPrecociousChild adorably precocious]] for his age, and that's saying something since Boxwood Terrace is full of [[ChildProdigy child prodigies]]. Lillian is the exception to that, since she's an AsianAirhead who CannotKeepASecret and at one point, believed clouds were made of cotton candy. Mindy is the middle point between the two. Mindy does know a lot about space for her age, but is prone to forgetting facts she learned in previous episodes.

[[quoteright:299:https://static.tvtropes.org/pmwiki/pub/images/fullsizerender_58.jpg]]
[[caption-width-right:299:Lillian, in all her HD glory]]
-->'''Voiced by''': Amelia Shoichet Stoll
Lillian is a minor character who makes her debut in "The Grandest Canyon". She is Mindy's girly friend. Lillian is a sweet, innocent girl, if slightly airheaded at times.

* ADayInTheLimelight: "Fact Or Fiction?" gives her the biggest role in an episode thus far.
* AgentMulder: Like Mindy, she believes in witches and ghosts and such. She even believes that clouds are made of cotton candy in "Fact Or Fiction?".
* AscendedExtra: Lillian gets bigger roles and more appearances starting in season 2, along with other characters like Mitchell and Dr. Skelley. This is likely because of their popularity in the fandom.
* AsianAirhead: Downplayed. She's Asian, but is slightly ditzy at times such as not knowing what perspective is, telling Mindy what her "surprise" birthday present was, and easily believes that Halloween is magical. Not to mention the whole "clouds are made of cotton candy" debacle in "Fact Or Fiction?".
* TheBusCameBack: She '''finally''' returns in "Mindy Turns Five", where she gets some much-needed development, and hangs out with the rest of Mindy's friends. She is also finally seen in the beautiful HD animation that Giant Wheel Productions, Studio Vysnc, and Enchanting Studio Limited currently do for the show, as opposed to the ugly, low-budget animation she was first seen in, in early season 1. It is just ''glorious'' seeing her in HD.
* TheCameo: Lillian makes cameos in "Kid-Kart Derby", "Mindy's Meteorite Stand", "Racing on Sunshine", and "Mars Rock for Mom".
* CannotKeepASecret: Lillian is terrible at keeping secrets, as she told Mindy what her birthday present was in "Mindy Turns Five".
* CheerfulChild: Well, obviously.
* TheCutie: Sweet, innocent, lovable. Yep, definitely fits the bill.
* TheDitz: Lillian isn't exactly the sharpest tool in the shed. She didn't know what perspective was, she blabbed out what her surprise present was to Mindy, easily believes that Halloween is magical, thinks that Sunspot wears a costume, and believed that clouds are made of cotton candy.
* DressedToPlunder: In "That's One Gigantic Pumpkin, Jet Propulsion!", she dresses up as a PirateGirl, and her outfit is a pretty typical pirate outfit that includes the following tropes.
** EyepatchOfPower: She wore an eyepatch.
** HookHand: She had a hook on one of her hands.
** TalkLikeAPirate: Lillian even throws in an "Deliver me lumber!" for good measure at one point.
* {{Expy}}: Appearance-wise, she resembles Sonya Lee from ''WesternAnimation/LittlePeopleEgmont''.
* FacialProfiling: She's an Asian girl with almond-shaped eyes.

** To Mitchell. They are both friends of Mindy, and two of the most popular recurring characters. However, they are different in many ways. Lillian is gentle, innocent, easily excitable, and a bit air-headed. Mitchell is easily pissed off, prideful, anti-social, and smart for his age. Furthermore, Lillian is an AgentMulder who is purely good, while Mitchell is a firm AgentScully who hides his good traits. Despite this, the very little amount of interaction they had in "That's One Gigantic Pumpkin, Jet Propulsion!" seems to prove that they are on somewhat good terms with each other. Justified as Lillian is best friends with Mindy, while Mitchell seems to like her a bit, which means that they are going to end up hanging out.
** She's also a foil to Sydney. Both are the very kind-hearted and imaginative girls in their respective groups. But while Sydney is smarter and, while imaginative, knows how to separate fiction from fact, Lillian is more air headed and easily believes in the supernatural.
* GirlsLoveStuffedAnimals: Lillian owns a teddy-bear named Fluffy Bear.
* GirlyGirl: '''And how!''' Lillian wears a big pink bow in her hair and a dress, and loves to play with dolls, and have tea parties.
* GirlyGirlWithATomboyStreak: She usually acts feminine, but lets her tomboyish side show when she dresses up as a pirate in "That's One Gigantic Pumpkin, Jet Propulsion!".
* GracefulLadiesLikePurple: Part of her dress is purple. She's graceful in the sense that she's a GirlyGirl who excels at gymnastics.
* HairColorDissonance: She is likely supposed to have black hair, yet it appears to be indigo. Lillian is the only character on the show to have an unnatural hair color.
* HalloweenCostumeCharacterization: At Halloween, Lillian wears a pirate costume, showing HiddenDepths - she's more than just a girly girl.
* HiddenDepths: She finally gets some in "Mindy Turns Five". She is revealed to be bad at keeping secrets, and she also does gymnastics. She can even do a flawless somersault.
* KindheartedSimpleton: Airheaded she may be, but she's still very gentle and polite.
* TheMcCoy: Fits this role in the FreudianTrio with Mindy and Mitchell. Lillian is more emotional and kind than both of them.
* NiceGirl: Lillian is friendly and polite to pretty much everyone. She is by far one of the nicest characters on the show, rivaling Jet, his parents, Sydney, and Bergs.
* NiceMeanAndInBetween: She's the Nice to Mitchell's Mean and Mindy's In-Between. Lillian is kind-hearted and loving, and the most innocent of the trio.
* NoFullNameGiven: Her surname is presently unknown.
* PinkMeansFeminine: Wears a pink bow in her hair, and she is by far the most feminine character on the show.
* PirateGirl: Lillian dresses up as one in "That's One Gigantic Pumpkin, Jet Propulsion!".
* PutOnABus: After "Mindy's Meteorite Stand", she disappeared for a while with no explanation. She returned in season 2, though.
* RedOniBlueOni:
** She and Mindy are the Blue Onis to Mitchell's Red Oni, as they both get less angry than he does.
** They are also the Red Onis to Mitchell's Blue Oni, as those two are very excitable while Mitchell is calmer.
* SatelliteCharacter: Downplayed. While Lillian does have a distinct personality, almost all of her episode appearances have to do with Mindy in some way (having a sleepover with Mindy, spreading false info to Mindy, having a tea party with Mindy, etc). It seems that Lillian only hangs out with Mitchell when Mindy is also there.
* SavvyGuyEnergeticGirl: She and Mindy are the Energetic Girls to Mitchell's Savvy Guy, as they're both energetic and easily convinced while he's more skeptical.
* ShoutOut: Lillian is based off of a character from one of the shorts that Craig Bartlett made for ''Series/SesameStreet'', called "Lillian, Big Sister". She has the name of the big sister from the short, but the appearance of the little sister, which causes fans to believe that she has an unnamed older sister who wears yellow clothing.
* SmartDumbAndInBetween: Lillian is the Dumb to Mitchell's Smart and Mindy's In Between. Mitchell is incredibly intellectual and [[AdorablyPrecociousChild adorably precocious]] for his age, and that's saying something since Boxwood Terrace is full of [[ChildProdigy child prodigies]]. Lillian is the exception to that, since she's an AsianAirhead who CannotKeepASecret and at one point, believed clouds were made of cotton candy. Mindy is the middle point between the two. Mindy does know a lot about space for her age, but is prone to forgetting facts she learned in previous episodes.
* SmartJerkAndNiceMoron: The Nice Moron to Mitchell's Smart Jerk. Mitchell is quite smart for a kid his age, and he's also very blunt and snarky, with a high-and-mighty attitude at times. Lillian, on the other hand, is ditzy and forgetful, but makes up for it with her politeness and sweetness.
* TokenMinority: Lillian is Chinese-American. The fact that she was Asian was obvious due to her features, but her nationality wasn't confirmed until March 2021.
* TomboyAndGirlyGirl: The girly girl to Mindy's tomboy.

[[folder:Dr. Rafferty]]
!!Dr. Rafferty
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/dr_rafferty.png]]
-->'''Voiced by''': Creator/KeeganConnorTracy (English), Carmen Lugo (Spanish), Andrea Laudon (Hungarian), Jang Eun-suk (Korean)
Dr. Rafferty is Sean's scientist mother, who works at the DSA. Her assistant is Dr. Bergs.
----
* AffectionateGestureToTheHead: She gives one to Sean in "Face on the Fritz".
* AffectionateNickname:
** Sean calls her "Dr. Mom" as of the episode "Constellation Prize".
** A few of the other children have referred to her as "Dr. Sean's Mom".
* AllOfTheOtherReindeer: Implied in "Visit to Mom's Office". When Jet tells Dr. Rafferty that he is an alien from Bortron 7, Dr. Rafferty assumes that he ''feels'' like an alien, and she mentions that she felt like an alien when she was a kid.
* AmazinglyEmbarrassingParents: In "Project Pluto", she unintentionally embarrasses Sean by mentioning that when he was four, he insisted on carrying a little purple hippo plush around.
* BlondeBrunetteRedhead: The Redhead to Bergs' Blonde and Skelley/Peterson's Brunette (her hair is a reddish shade of brown).
* BrainyBrunette: Is an accomplished scientist, and has reddish-brown hair.
* TheCameo: Made one in "Every Day is Earth Day".
* EarlyBirdCameo: She made a cameo appearance in "Beep Has the Blues", where she analyzes Boop's camera on Mars, and is incredulous when she sees a footprint on the surface and it disappears. Her actual debut was in "Visit to Mom's Office".
* {{Foil}}: To Dr. Bergs. They are both DSA scientists who are friendly and teach the kids various things about science. Dr. Rafferty is competent and is almost never used for jokes, while Dr. Bergs is a bit of a bumbling BigEater who is often used for jokes, especially if it involves his coffee obsession. On the flip side though, Dr. Bergs has HiddenDepths - being related to Lone Star himself, while Dr. Rafferty doesn't have that kind of depth aside from her hobbies. While there is her apparent AllOfTheOtherReindeer childhood where she "felt like an alien", it is only implied and has never been mentioned since "Visit to Mom's Office".
* FriendlyTickleTorture: In "I Feel The Earth Move", she tickles Sean's belly.
* GoodParents: Dr. Rafferty is an excellent mother to Sean.

** "Freebird" reveals that she likes to study birds.
** "Mars Rock For Mom" reveals that she likes to collect rocks.
* TheMentor: She is the closest thing the show has to an actual teacher, along with Face 9000.
* NervousWreck: She can be pretty nervous when under pressure. Examples would be in "My Fair Jet", where she is anxious about the DSA Open House not going well, and in "Astronaut Ellen Ochoa", where she, along with her co-workers, is nervous about Ellen Ochoa's visit to the DSA. It's possible that Sean gets his NervousWreck tendencies from her.
* OnlySaneWoman: Dr. Rafferty is shown several times to be smarter than her coworker, Bergs. In fact, she is the smartest human character on the show. (The smartest character in the entire show is Face 9000).
* OrangeBlueContrast: Her blue shirt contrasts with Bergs' orange shirt.
* PinkMeansFeminine: Dr. Rafferty has pink glasses and earrings.
* SimilarSquad: To her son Sean, with whom she has SharedFamilyQuirks, namely them being the most nervous of their respective teams. Like his mother, Sean is fairly intelligent and level-headed (most of the time).
* SmartPeopleWearGlasses: Dr. Rafferty is an accomplished scientist, and wears glasses.
* TheSpock: Dr. Rafferty serves this role in the FreudianTrio with Skelley and Bergs. While Rafferty is more open and friendly than most examples of the trope, she's the most intellectual of three and even though she's a NervousWreck at times, at least she has more self-composure than Bergs.
* StacysMom: Jet had a crush on her for a few episodes (most prominent in "Visit to Mom's Office" and "Asteroid Patrol"), though this was eventually phased out.
* TrueBlueFemininity: She wears a blue shirt.
* UnnamedParent: Her first name is unknown.
* YouRemindMeOfX: In "Visit to Mom's Office", she says that Jet reminds her of herself when she was a kid. For context, Jet ended up telling her that he's an alien from another planet, but Dr. Rafferty interprets this as him pretending to be one, and says that she felt like an alien when she was kid, too. Dr. Rafferty also admires how Jet's got it all worked out.
* YouthfulFreckles: Dr. Rafferty appears to be relatively young, and she has freckles just like her son.

!!Dr. Bergs
[[quoteright:296:https://static.tvtropes.org/pmwiki/pub/images/drbergs.png]]
-->'''Voiced by''': Creator/BrianDrummond
Dr. Bergs is Dr. Rafferty's co-worker.

* AmbiguousSituation: In "A Visit to the Planetarium", a man named Don appears in the booth to let Jet, Sean, Sydney, and Sunspot into the planetarium. Only his silhouette is shown, but it resembles Bergs. The kicker? They're both voiced by Brian Drummond. It's unknown if Don and Bergs are the same person, and if this would make his first name Don.
* AgonyOfTheFeet: In "Astronaut Ellen Ochoa", he hurts his foot.
* BigEater: Bergs loves to eat pies and other sorts of pastries.
* BlondeBrunetteRedhead: The Blonde to Skelley/Peterson's Brunette and Rafferty's Redhead.
* BunnyEarsLawyer: Despite his bumbling, Bergs is a very smart scientist who helps the kids learn facts about space.
* ButtMonkey: Can be this at times. Especially prominent in season 2, where Sunspot keeps stealing his watch.

* WomenAreWiser: Dr. Rafferty is shown several times to be smarter than her coworker, Bergs. In fact, she is the smartest human character on the show. (The smartest character in the entire show is Face 9000).

* {{Expy}}: Appearance-wise, she resembles Sonya Lee from ''WesternAnimation/LittlePeople''.

* LovedByAll: Ellen seems to have this reputation amongst the Boxwood Terrace population. All the DSA scientists are eager to impress her, the kids taking a liking to her immediately, and even Floyd the squirrel is nice to her.

* HundredPercentAdorationRating: Ellen seems to have a reputation amongst the Boxwood Terrace population. All the DSA scientists are eager to impress, the kids taking a liking to her immediately, and even Floyd the squirrel is nice to her.

* HotScientist: Dr. Rafferty is a scientist, but is incredibly beautiful. So much so, that Jet had a crush on her (but it went away in later episodes).

* AmbiguousDisorder: Since Sean is heavily neurodivergent-coded, it's possible he inherited it from Dr. Rafferty. It helps that she said she felt like an alien, which is a common metaphorical description of what autism is like. She even speculates InUniverse that Jet is the same way (although she doesn't know that he's actually an extraterrestrial).

** In "Astronaut Ellen Ochoa", Bergs' already-established caffeine addiction is taken UpToEleven, where he drinks lots of coffee to compensate for his nervousness and is devastated when his Ellen Ochoa coffee mug breaks. As such, Dr. Skelley advises him to drink decaf instead.

Dr. Rafferty is competent and is almost never used for jokes, while Dr. Bergs is a bit of a bumbling BigEater who is often used for jokes, especially if it involves his coffee obsession.

While there is her apparent AllOfTheOtherReindeer childhood where she "felt like an alien", it is only implied and has never been mentioned since "Visit to Mom's Office".

* DumbBlonde: Not exactly ''dumb'', per se. He's smart, but not so much compared to Dr. Rafferty.
