Members of Odd Squad, the organization founded to stop oddness. Every employee is a child.

  • Badass in a Nice Suit: Most investigation and management agents wear suits.
  • Bunny-Ears Lawyer: The characters are very quirky, yet all competent.
  • Chaotic Good: More than a bit weird in personality, organization, and techniques, but are definitely good people tying to stop odd and help others.
  • Hero of Another Story: While the only characters to really get focus on their cases are the main characters, episodes pop up here and there to show what the other agents work on.
  • Kid Detective: Well, they're all kids, and must do some detective work in order to stop oddness.
  • Little Miss Badass: Most female agents are this to some extent.

  • Platonic Life-Partners: See above.

    Season One 


Agent Olive

Played by: Dalila Bela
A 12-year-old veteran agent of the Odd Squad. She used to have another partner before she had Otto; it was unclear whom until Wham Episode Training Day.

Agent Otto

Played by: Filip Geijo
A 10-year-old new recruit of the Odd Squad, Otto is fascinated by everything that goes on around him. Being around Olive, his current partner, hasn't changed him—he's still the life of the party. Sometimes Olive gets annoyed at him, but together they make the perfect team.

Ms. O
Played by: Millie Davis

Ms. O, formerly Agent Oprah, is the head of Odd Squad. She delivers cases to agents who then go on their way to solve them. She is tough, grumpy, short-tempered, and easily angered, but she will always lend a helping hand to those agents who struggle. She used to have Agent O'Donahue for a partner before he officially retired.

Agent Oscar
Played by: Sean Michael Kyer

The head scientist of the Odd Squad Lab. Goofy and ditzy, he has a gadget for almost everything. He takes care of his gadgets, and he always greets others with "Hey guys!" He is renowned for creating addable gadgets.

  • Absent-Minded Professor: Genius, but can be a bit forgetful.
  • Adorkable: He's awkward but endearing.
  • Gadgeteer Genius: He makes the gadgets for the odd squad agents. Though making gadgets is a thing every scientist does, he's special for the fact he created addable gadgets, a very important tool in Odd Squad.
  • Genius Ditz: He's very smart, but can be a bit awkward.
  • Labcoat of Science and Medicine: A trademark of his department.
  • Mad Scientist: While he's not evil, a lot of problems occur due to one of his inventions going wrong.
  • Put on a Bus: Leaves #13579 to head the Science Headquarters.
  • Teen Genius: See Gadgeteer Genius.
    • A sidenote: he ages further in the Season 2 premiere, due to his actor aging in real time. In-universe, this is due to an aging-gadget going off.
    Ms. O: Something's different about you...
    Oscar: Oh yeah. This Make-You-Older-inator went off. I like the new voice, though.

    Season Two 

Agent Olympia
Played by: Anna Cathcart

Olive and Otto's replacements and the main characters of the second season. Olympia was a great student at the academy and Otis came from... somewhere. They are introduced in the second season premiere.

  • Beware the Nice Ones: Sure, Olympia's a Genki Girl, but she's not afraid to show her mean side.
  • Character Blog: Oddtube was a 20 episode YouTube series starring Olympia.
  • Contrasting Sequel Main Character: While only a new cast for a new season, this still applies as Otis and Olympia have the exact opposite dynamic as Olive and Otto, save for Olympia being the one who's the protocol fiend, with Olympia being the chipper bouncy one while the more reserved Otis is frequently sighing in irritation at her antics.
  • Genki Girl: Olympia is very enthusiastic.
  • Fangirl: Olympia's one of Otto and Olive, and freaks out every time she gets to meet them.
  • Foil: To Ohlm. Both of them were excellent students at the Odd Squad Academy. But while Olympia was happy to just be an agent, Ohlm wanted to become the Big O immediately. This resulted in him plotting to take over Odd Squad.
  • Meganekko: Olympia's cute and a glasses wearer.
  • Nice Girl: Olympia just wants to be the best agent she can.
  • Savvy Guy, Energetic Girl: Olympia is a Genki Girl while Otis is more reserved.

Agent Otis
Played by Isaac Kragten

Otto's replacement and one of the main characters of the second season. He came from... somewhere. Like Olympia, he is introduced in the second season premiere.

  • Absurd Phobia: Otis is not a fan of ducks. He thinks it's his old family coming for him.

  • Dark Secret: He used to be a villain.
  • Flight: Is revealed to be able to fly.
  • Heel–Face Turn: Is revealed to be the White Sheep of a villainous duck family.
  • Mysterious Past: Like in Oscar's words, "Then where did he (Otis) come from?" Otis's past is the main mystery of the second season. It is hinted to have something to do with villains and is confirmed .
  • Raised by Wolves: He was raised by ducks.
  • Read the Freaking Manual: Otis has not read the Odd Squad handbook at all. This is contrasted with Olympia, who loves to get her hands on anything OS related.
  • Savvy Guy, Energetic Girl: As noted above, he is the Savvy Guy to Olympia's Energetic Girl.
  • Socially Awkward Hero: When he started off, Otis wasn't very good at communicating with others. He got better.

Agent Oona

Oscar's assistant and eventual replacement, becoming the head of the Science Department.

     Other Agents 

Agents Oren and Olaf
Oren (left) and Olaf (right)
Two recurring supporting characters. They are often opponents of Otto and Olive.

  • Absurd Phobia: Oren seems to be scared of pancakes.
  • Blatant Lies: During a "Meet the Agents" sequence, Oren says that he's great at sharing (followed by a clip of him and Olaf fighting Olive and Otto over new office chairs) and that's he's a very hard worker (followed by a clip of him and Olaf lounging in the ball pit).
  • Catchphrase: For Olaf: "I'm Olaf!"
  • Cloudcuckoolander: Olaf is possibly the most odd-ball member of Odd Squad, which is saying something.
  • Hidden Depths: Olaf tends to be simple-minded, but can have surprising moments of genius. For example, in one episode, Otto keeps shrinking and Olive has to team up with Oren and Olaf to find a cure. Olaf proves to be the only one who knows the secret to reversing the shrinking, and his normally very limited vocabulary begins to approach Sesquipedalian Loquaciousness.
  • It's All About Me: Oren.
  • Noodle Incident: "If Ms. O offers to send you to Blobsylvania to count blobs, DO. NOT. GO." Subverted in that we get to see a clip of Oren and Olaf counting blobs.note 
  • Perpetual Smiler: Olaf is almost always happy and excited, which sometimes gets on Oren's nerves.
  • The Reveal: Olaf is a werewolf
  • Sarcastic Clapping: In Blob On the Job.
  • Sitcom Arch-Nemesis: To Olive and Otto.
  • Those Two Guys: Agents who appear every so often to annoy our heroes.
  • Trademark Favorite Food: Olaf loves potatoes.
  • True Companions: Really do care for each other.

Agent Orchid
One of the younger agents, she is sassy and particular.

Agents Octavia and Oz

Octavia, another agent, will appear here and there in Season One. She is not the smartest tool in the shed, but always tries to be helpful. Her partner, Oz, is only seen in flashbacks, and for good reason.

  • The Ditz: Agent Octavia. She doesn't always understand things.
  • Invisibility: Agent Oz, thanks to looking at a gadget the wrong way.
  • Nice Girl: Is there to help, even if she doesn't know what's she's doing.

Agent Ohlm
Introduced in the first season finale. Quite dimwitted.
  • Bond Villain Stupidity: Ohlm was so focused on getting revenge on Odd Squad an creating a black hole, that he didn't stop to think about himself getting sucked into his own black hole. He could have used a get away vehicle or something to escape his own doom.
  • Crouching Moron, Hidden Badass: While looking dumb, he is still a good agent and succeeds in getting the remote back.
  • Evil All Along: Revealed to have been plotting to take down Odd Sqad since he started working here, because he wasn't made a Mr. O immediately upon graduating the academy.
  • Foil: To Olympia. Both of them were excellent students at the Odd Squad Academy. But while Olympia was happy to just be an agent, Ohlm wanted to become the Big O immediately. This resulted in him plotting to take over Odd Squad.
  • Four Eyes, Zero Soul: When Ohlm reveals his true colors in the Season 2 finale, he puts on a pair of glasses.
  • Obfuscating Stupidity: He used his dumbness to hide his real plans to destroy Odd Squad.
  • Repetitive Name: His full name is Ohlm Ohlm.
  • Ungrateful Bastard: You'd think that Ohlm would have been grateful that the agents were willing to save his life after they found out his true colors, but no, he continues threating to destroy the company after they closed his black hole and doesn't even thank them. Yeah, he had that grounding coming.
  • Walking Spoiler: He's been faking his ditziness to help villains to sabotage his precinct, so he could manipulate events to get Ms. O fired and destroy Odd Squad.
  • You Are Grounded: Is grounded by his parents when defeated by Ms. O.

Agent Obfusco
He's an expert on dealing with oddities and trains current agents. However, he talks in a weird way, which means it hard for agents to understand him.

Doctor O
Obviously, the Doctor of #13579.
  • Catchphrase: "Trust me, I'm a doctor".
    • Also "WHAT'S NEXT??".
  • The Comically Serious: She is less prone to acting silly, and gets down to business. Her abrupt deadpan and straight face contrast with everyone else's behavior, making her funny.
  • I'm a Doctor, Not a Placeholder: Dr. O is always reminding everyone that she's a doctor.
  • Put on a Bus: Departs for the Odd Squad Space Station in "Doctor O, Party Time, Excellent."
  • Super Doc: The only one at #13579, and knows how to treat both oddities and normal illnesses.
  • Trust Me, I'm an X: She says stuff like this often.

Agent Oksana
The cook of the precinct. Is neither talkative nor emotional.

A new employee, he works with odd creatures. He's an expert at dealing with them and taking care of them.

  • Fluffy Tamer: His expertise extends to frightening animals, and cares for them as well.
  • Friend to All Living Things: He is very fond of creatures and will risk his life to give one the chance of survival.
  • Mellow Fellow: So laid-back it's amazing he doesn't slide out of his chair onto the floor.
  • Nature Lover: Comes with his love of animals.
  • The Watson: Ends up having to ask the questions, such as in A Case of the Sillies where he needs to know about measurement quantities.


Odd Todd
A former Odd Squad agent who was the best at solving many cases and winning many awards (including the one for most awards). He is really good at solving math problems in his head, leading to his successes. Eventually, he started to believe that the Odd Squad's quest to stop odd things from happening was wrong, so he started to deliberately cause odd cases to be unsolved. He got fired for this, then came back to cause a Pie-nado in HQ and re-invent himself as a villain.

One of the squad's most consistent enemies.
