!!Betty Boop
http://static.tvtropes.org/pmwiki/pub/images/imagesCA2AF8LP_9562.jpg

A 16 year old 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.

!!Bimbo

The 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 MickeyMouse. 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, [[InterspeciesRomance 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.
-----
* AllMenArePerverts: Er, dogs anyway.
* ArtEvolution: 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.
* CatchPhrase: "Okay, colonel!"
* ChuckCunninghamSyndrome: As mentioned above, he was abandoned post-1933 due to the Hays Office objecting to Betty having InterspeciesRomance with him.
* HalfDressedCartoonAnimal
* InterspeciesRomance: With Betty, after she became human.
* MeaningfulName: During the 30's, anyways--back then, "Bimbo" was slang for "loser".
* SatelliteCharacter: Really dosen't have much of a personality.
* UnfortunateName: 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 Clown

The original star of the Max Fleischer cartoon studio from the ''OutOfTheInkwell'' series, [[TheSilentAgeOfAnimation Silent Age cartoon veteran]] Koko the Clown made occasional appearances in the shorts as a copatriot of Betty and Bimbo.
-----
* CartoonCreature: Koko may be a clown, but he's certainly not human--he's more of an ink creature.
* TheCameo: Briefly appeared in his small form in the short "Minnie the Moocher".
* ChuckCunninghamSyndrome: Didn't make that many appearances in this series.
* NonIronicClown
* ThoseTwoGuys: When he teams up with Bimbo, such as in "Snow White".

!!Pudgy

After 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 WaltDisney's [[PlutoThePup Pluto]], but arguably much cuter.
-----
* CharacterFocus: Some episodes would be entirely centered around him.
* PreciousPuppies
* KindheartedCatLover: Befriends a small kitten in one episode.
* RidiculouslyCuteCritter
* TheVoiceless

Betty's grandpa, who happens to be a genius inventor.
-----
* AbsentMindedProfessor
* AscendedExtra: Was a recurring character of the later Betty Boop shorts, but was apparently liked enough to headline a ColorClassics short "Christmas Comes But Once A Year".
* BigDamnHeroes: By virtue of CarFu in "Be Human".
* CatchPhrase: "Ahahahaah! ''I've'' got it!"
* CoolOldGuy
* GadgeteerGenius
* MacGyvering
* MrFixit
