- Flat Character: For the most part, given that they're supposed to be easily identifiable and kinda predictable. They dip into Static Characters at times, since they can show some Hidden Depths or have a new ability, but for the most part, they remain completely one-dimensional.
- Sitcom Character Archetypes: Accordingly, all of the main characters fall into this, although it's a little more dynamic than usual. Let's see:
- The Horse's role is to be the Straight Man a.k.a. The Square to all of the shenanigans around him. Alternatively, he's the "sagacious dispenser of advice" and "the classy player" due to his paternal role and often having to educate his children and his status as the best lawyer in the firm Libertore & Associates. He can also fall into The Wisecracker, since he simply loves being a Pungeon Master.
- Olivia is comparatively The Bully due to her more rebellious personality out of the three orphans, as well as her more intolerant attitude towards her siblings and being proved wrong. She also fits into The Charmer since she's the most worried about personal status and the most socially invested out of the three.
- Ethan is The Dork being the most knowledgeable of all in terms of political systems and matters, while also being the most gawky in comparison to the rest.
- Sabrina is a mixture of The Wisecracker with her snappy and rebellious attitude, The Goofball with her outlandish yet still childish ideas and her tendency to be innocent in every account and The Precocious due to her young age and her belief on childhood tales like Santa.

- Nay-Theist: Hinted at when he explains to Sabrina the way the Santa's Existence Clause works, which mirrors the way atheists think and view the world. Being the family-friendly program this one is, it doesn't matter much.The Horse: You can't be good just to expect a reward. You have to be good just to be good.

- Standard '50s Father: A Parody of such, given the kind of show this one is.The Horse: Sabrina, you and Olivia and Ethan are the best things that have ever happened to me, and if it took your parents dying for you to be part of my life, well, then I'm glad your parents died.Sabrina: Oh, you don't mean that.The Horse: No, I do, I'm glad your parents are dead and are never coming back.
- Who Names Their Kid "Dude"?: Since it seems like it's his real name, it's a really weird decision to name your kid the same way as his species.
- Workaholic: Used to be this before he adopted the children. Mr. Libertore laments that Horse has gone soft.
- Mr. Libertore: I can't say I'm not disappointed. Time was, I thought you were a go-getter.
Played by: Joelle Clarke Real Actress

- Belligerent Sexual Tension: With Goober.
- Blonde, Brunette, Redhead: Blonde to Ethan's Redhead and Sabrina's Brunette.

Played by: Bradley Hitler-Smith Real Actor
The middle child.
- A Boy, a Girl, and a Baby Family: The Boy of the three orphans.
- Ascended Extra: In-universe, Bradley creates a Horsin' Around spin-off focused on Ethan who has grown up and adopted 3 young horses.
- Blonde, Brunette, Redhead: Redhead.
- Catchphrase: "Yowza yowza bo bowza!" (This never really caught on, as demonstrated when he uses this line in the first Christmas Special.)
- Character Filibuster: He would often fly off into long tangents involving politics, national issues and serious discussion about dark matters even if they had nothing to do with what they were discussing or wondering about.
- Forced Meme: His catchphrase of "Yowza yowza bo-bowza!", not even the studio audience reacts to it (say for one guy clapping).
- Happily Adopted: With the Horse.
- Heartwarming Orphan: Deliberately Invoked.
- Nerd Glasses: He has a pair.

- The Smart Guy: He's quite well-versed for his age and really invested in politics.
- Youthful Freckles: In a similar way to Sabrina, he has freckles, although in this case it's because he's a redhead.
Played by: Sarah Lynn Real Actress
The youngest one of the orphans.
- A Boy, a Girl, and a Baby Family: While Sabrina is 5 and way older than a baby, she fits The Baby as she's still the youngest one of the three.
- The Baby of the Bunch: She's the youngest one of the orphans and the most insecure.
- Blonde, Brunette, Redhead: Brunette.
- Breakout Character: Apparently, her in-universe popularity was so big, she alone started to take episodes that were supposed to go to other characters.
- Catchphrase: "That's too much, man!"
- Daddy's Girl: Out of the three, she's the closest one to The Horse. Reality Subtext as Bojack Horseman and Sarah Lynn were pretty close during production, although not in a healthy way.

- Happily Adopted: With The Horse, although she still wishes every so often her parents were still alive.
- Heartwarming Orphan: Invoked.
- Make a Wish: For Christmas, all she wished was for her parents to come back. It didn't work.
- Sitcom Character Archetypes: Sabrina is a mixture of The Wisecracker with her snappy and rebellious attitude, The Goofball with her outlandish yet still childish ideas and her tendency to be innocent in every account and The Precocious due to her young age and her belief on childhood tales like Santa.
Played by: N/A Real Actress
- Ambiguously Brown: She has a darker skin tone than most of the cast, but it's still lighter than other people. Not to mention her mostly puffy hair.
- Hypercompetent Sidekick: To Mr. Libertore, being his assistant and all.
- Implied Love Interest: Being the kind of show this one is, her flirting with The Horse is enough to showcase them as possible love interests, yet it's never explicit enough to confirm it.
- Interspecies Romance: With The Horse, a....Horse.
- Lampshaded Double Entendre: Whenever she and The Horse would flirt, this would often be present:The Horse: Tracey, if you wanted to see my briefs, all you had to do was ask.Tracey: Why, if I didn't know any better, I'd say you were flirting with me. (Audience woos)
- Plucky Office Girl: A Parody of the trope, as Tracey checks every single requirement for it.
- Ship Tease: With The Horse.
- Sassy Secretary: Quite willing to make a snappy comeback and snark in a friendly tone.
- Sexy Secretary: Oh, yes. From her dress, her cleavage and skirt. She particularly loves to Show Some Leg.
Played by: Herb Kazzaz Real Actor
The Horse's boss at Libertore & Associates.
- Benevolent Boss: Downplayed. He's not a saint by any chance, but if it's clear that you work hard and what you ask doesn't conflict in any way with the company or can be reasonable, he'll grant it with certain conditions such as The Horse asking for a small vacation to celebrate Christmas with his family.
- Descended Creator: In-Universe example. Mr. Libertore's voice is provided by the show's creator, Herb Kazzaz.
- Disappointed in You: His opinion of The Horse nowadays: the guy seems to care more about his kids rather than being #1 at work, complete opposite of how he used to be.
- The Grinch: Making money and working are the two number one priorities in his mind and predictably (initially) forbids The Horse to take the Christmas day off to spend time with his kids, only relenting when it's only the Christmas morning off instead of the whole day.
- Jerk with a Heart of Gold: Not a nice guy or selfless boss, but he does end up relenting and gives The Horse half the day off to spend time with his kids.
- Jerk with a Heart of Jerk: Then again, it's only half day instead of a full one like he asked and once it's over, he must return immediately.
- Mean Boss: Arrogant, standoffish and greedy by the show's standards. A professional for sure, but expects everyone to be as committed to the job as he is.
- Right Behind Me: A clever variation. After The Horse goes into a tirade against Libertore, Tracy tries to get him to stop talking as if he's standing behind him. When he gets the message, he simply stops and looks behind only to find there's no one. As it turns out, he's been hearing through the intercom.
- The Voice: He never appears on screen, only speaking through the intercom at Tracy's desk.
- Workaholic: Dedicated to the job like crazy.
Played by: Richie Osborne Real Actor
An annoying neighbor who casually drops by at the Horse' house, much to everyone's detritement.
- A Day in the Limelight: "Goober Goes Home"note .
- Belligerent Sexual Tension: With Olivia.
- Drop-In Character: A parody of the concept, his only purpose was to come in and act Totally Radical.
- The Friend Nobody Likes: He just comes and goes whenever he feels like it, mooches out food, annoys Olivia, Sabrina and Ethan barely put up with him and the reason he's allowed in is because The Horse doesn't mind him and even he can be kind of a dick to him when he's had enough. Otherwise, no one can stand Goober, although from Olivia's point-of-view, it's more a case of Slap-Slap-Kiss.
- Mall Santa: During "Sabrina's Christmas Wish".
- Nice Character, Mean Actor: Well, Goober wouldn't be what you'd call "nice", but still: annoying and unwanted is a step up from a sexual offender and all around sleaze bag who nowadays runs a drug ring and a low-level whorehouse like Richie Osbourne.
- Phrase Catcher: "Go home, Goober!"
- Ship Tease: With Olivia.
- The Thing That Would Not Leave: No wonder the family always yells for him to leave when he annoys them.
- Throw the Dog a Bone: Implied in "Goober Goes Home".
- Undermined by Reality: In-Universe, a lot of the character's wacky antics were seen in a different light after the actor was later arrested for sex crimes.
Exactly What It Says on the Tin. They speak and shout during the taping of the show.
- Audience Participation: Constantly yell, shout or react to the events unfolding in the set. They can get way too involved with the story and it does take a bit from the actors not to directly interact with the audience.
- Audience Surrogate: Absolutely has nothing to do with the out-of-universe public that watch the show. Nope.
- Shipper on Deck: At least the one guy in the Christmas Special seems to ship The Horse and Tracy, and Olivia and Goober.
