A flapper girl, looking for a good time and good at heart. Was gradually toned down post-1933, but is still remembered today as the peppy, cute youth of her early days.
- Alliterative Name: Betty Boop.
- Ambiguously Jewish: Hinted at in "Minnie the Moocher".
- Anthropomorphic Shift: Originally appeared as a cartoon poodle, but gradually morphed into a cartoon human.
- Catch Phrase: "Boop-boop-a-doop!"
- Early Installment Character-Design Difference: Betty was originally a dog; however, later her species was changed to a human. She also originally had red hair according to her only colored classic cartoon (Cinderella) but all later appearances give her black hair.
- The Flapper: She was born as a caricature of this.
- Good Bad Girl
- Hartman Hips
- Hello, Nurse!: She got this reaction in most of her cartoons before the Hays Code kicked in.
- Impossible Hourglass Figure: Betty Boop was described in a 1934 court case as: "combin[ing] in appearance the childish with the sophisticated — a large round baby face with big eyes and a nose like a button, framed in a somewhat careful coiffure, with a very small body of which perhaps the leading characteristic is the most self-confident little bust imaginable."
- Ms. Fanservice: She is regarded as one of the first and most famous sex symbols on the animated screen. Her popularity was drawn largely from adult audiences, and the cartoons, while seemingly surreal, contained many sexual and psychological elements.
- New Job as the Plot Demands
- Progressively Prettier: She went through such a process during her Art Evolution. She started out as an anthropomorphic dog, and somehow ended up a cute flapper girl.
- Puppy-Dog Eyes: A Trope Codifier alongside Bambi, considering theirs were the bases for Osamu Tezuka's, and by extension anime as a genre's, large eye style.
- Sexy Backless Outfit: Often wears these types of dresses.
- She's Got Legs: She's got some of the nicest legs ever drawn.
- So Beautiful, It's a Curse: In both the shorts Chess-Nuts and Boop-Oop-a-Doop where the bad guy lust for her and she need to be saved.
- Stocking Filler: Almost never seen without a garter on her left thigh.
- The Tease
- Vague Age: She's either a teenager or young adult, depending on the short.
BimboThe initial star of the Max Fleischer Talkartoons series of sound cartoons, Bimbo is a cartoon dog, bred of the stock rubberhose art style of the time and the Fleischers answer to Mickey Mouse. Betty was initially created to be his girlfriend, but ended up becoming so popular that Talkartoons became her own series, with Bimbo getting into many escapades with her, some of which were romantic. However, once the Hays Office grew its claws in 1934, Bimbo was immediately abandoned due to the Codes rules against bestiality.
- All Men Are Perverts: Er, dogs anyway.
- Art Evolution: In his early appearances, the animators simply could not make up their minds as to how Bimbo should be drawn, resulting in him constantly changing design between shorts, until they settled into a final sweater wearing design.
- The Bus Came Back: Despite being abandoned in the mid 1930's, he still appears in merchandise with Betty, albeit with the romantic implications sometimes downplayed or abandoned in favor of making him a friend of Betty. His name is rarely mentioned in merchandising though, due to how dated and unfortunate it can sound.
- Catch Phrase: "Okay, colonel!"
- Chuck Cunningham Syndrome: As mentioned above, he was abandoned post-1933 due to the Hays Office objecting to Betty having Interspecies Romance with him.
- Half-Dressed Cartoon Animal: Usually just wears a sweater, gloves and shoes. His early Talkartoons appearances often had him wearing just shoes and a hat.
- Interspecies Romance: With Betty, after she became human.
- Meaningful Name: During the 30's, anyways—back then, "Bimbo" was slang for "loser".
- Satellite Character: After Betty became a series regular, Bimbo was rarely seen without her company.
- Unfortunate Name: Of the "changed meaning" variety—back in the 30's, Bimbo was slang for "Loser." Making it a bit unfortunate to begin with.
Koko The ClownThe original star of the Max Fleischer cartoon studio from the Out of the Inkwell series, Silent Age cartoon veteran Koko the Clown made occasional appearances in the shorts as a copatriot of Betty and Bimbo.
- Cartoon Creature: Koko may be a clown, but he's certainly not human—he's more of an ink creature.
- The Cameo: Briefly appeared in his small form in the short "Minnie the Moocher". Fittingly, Betty pulls out him of an inkwell when she reaches for a pen, a nod to his original series.
- Canon Immigrant: He was brought over directly from Fleischer's silent-era series Out of the Inkwell as a side character for this series.
- Chuck Cunningham Syndrome: Didn't make that many appearances in this series.
- Non-Ironic Clown
- Those Two Guys: When he teams up with Bimbo, such as in "Snow White".
PudgyAfter Betty was cleaned up by the Hays Office, animator Myron Waldman decided to give Betty a new friend, a moon-faced puppy named Pudgy, to replace Bimbo (a character whom Waldman despised). In a sense, Pudgy is Fleischer's answer to Walt Disney's Pluto, but arguably much cuter.
- Character Focus: Some episodes would be entirely centered around him.
- Precious Puppies
- Kindhearted Cat Lover: Befriends a small kitten in one episode.
- Ridiculously Cute Critter
- The Voiceless
GrampyBetty's grandpa, who happens to be a genius inventor.
- Absent-Minded Professor
- Ascended Extra: Was a recurring character of the later Betty Boop shorts, but was apparently liked enough to headline a Color Classics short "Christmas Comes But Once A Year".
- Big Damn Heroes: By virtue of Car Fu in "Be Human".
- Catch Phrase: "Ahahahaah! I've got it!"
- Cool Old Guy: Just ask the orphans in the aforementioned "Christmas Comes But Once A Year".
- Gadgeteer Genius
- Mr. Fixit
