Odd Squad

Description

Odd Squad is a live-action children's educational comedy series where the entire workforce consists of kids who solve strange problems using math. The show follows agents from Precinct 13579, an investigation division of the Odd Squad organization. During the first season, the main agents are Olive and Otto, played by Dalila Bela and Filip Geljo. In the second season, the focus shifts to new agents Olympia and Otis, played by Anna Cathcart and Isaac Kragten.

Other employees, such as security officers, tube operators, and scientists, appear in selected episodes. Nearly all character names begin with the letter O. The agents receive their cases from their boss, Ms. O, played by Millie Davis, and travel through a network of tubes to reach their destinations. They solve each episode's plot by applying basic math concepts like addition, multiplication, and data graphs. When stuck, they often return to headquarters or the Mathroom, a sentient space that communicates through large paper fortune tellers, unfolding to reveal clues.

The agents also use gadgets created by the lab team. In season one, Agent Oscar, played by Sean Michael Kyer, runs the lab; he later gains an assistant, Agent Oona, played by Olivia Presti, who takes over after Oscar is promoted. Recurring villains appear, each with mathematically themed schemes. The third season, called Odd Squad Mobile Unit, moves the action from the precinct to a van, where four agents are assigned by the Big O to travel the world solving cases that local precincts cannot handle. The fourth season, Odd Squad UK, is set in a British Odd Squad location.

Cast and characters

Agent Olive (Isabela Moner, pilot; Dalila Bela, season 1): Referred to as a longtime employee of the Odd Squad, Olive began season one adapting to working with and training her new partner, Otto. Olive is usually calm, brisk and serious. She has a morbid fear of pies, which she acquired after saving her organization's building from a pie-related disaster caused by her former partner, Todd. In the season one finale, Olive departs the series along with her partner, Otto, to run a different Odd Squad precinct as Ms. O.

Agent Otto (Jaden Michael, pilot; Filip Geljo, season 1): Olive's partner and, in the first episode, the newest employee of the organization. In contrast to his partner's more serious demeanor, he is a more lenient, laid-back employee. Despite his lack of experience, Otto frequently uncovers the facts needed to solve the case at hand, even doing so in the absence of his more experienced partner. In the season finale, Otto departs the series to run another Odd Squad precinct as Mr. O with Olive as his partner.

Big O (Millie Davis, seasons 1-3): Known as "Ms. O" in the first two seasons, she is a very strict boss. She tends to yell (a habit seen less frequently as the series progresses) and is often seen sipping a juice box. Despite appearing younger than most of the agents, Ms. O's tenure at the precinct and her actual age remain a mystery. In-show, it is revealed that her actual name is "Oprah."

In the season two finale, Ms. O is promoted to the rank of Big O, the leader of the entire Odd Squad organization. She leaves the show after the Season 3 episode "Odd Off The Press" due to traveling to outer space, appointing Orpita, an agent-in-training, as the Little O to replace her. Agent Oscar (Sean Michael Kyer, seasons 1-2): Oscar was the precinct's head scientist, in charge of the laboratory. Other employees go to him for technical solutions.

Oscar is depicted as being very intelligent and having a quirky and goofy personality. He leaves the show after the Season 2 episode "Oscar Strikes Back," where he becomes the president of the organization's science division after the former president is dismissed for misconduct. He appoints Agent Oona to take over for him. Agent Olympia (Anna Cathcart, season 2): Introduced in the first episode of season two, Olympia joins the series to fill the opening left by the departure of Olive.

She was given early graduation from the organization's training academy. She is depicted as being very sociable and outgoing and having a generally happy and carefree personality. Agent Otis (Isaac Kragten, season 2): Like Olympia, Otis was introduced at the start of season two, brought in to fill the opening left by the departure of Otto. Unlike his partner, he has a more serious and socially reserved personality.

There are no records of him attending the organization's academy, but he is depicted as being the more seasoned member of the new team. He has a fear of ducks, revealed in the season two finale to be related to the fact he was once part of a family of villainous ducks. Ms. O took pity on Otis and trained him herself to become an Odd Squad agent. Agent Oona (Olivia Presti, season 2; special guest season 3): Initially Oscar's assistant, she takes up his position after his departure.

Like Oscar, she is depicted as having a quirky personality. Agent Opal (Valentina Herrera, season 3): Originally stationed at a precinct in the Arctic with Omar, she is competitive with a strong desire to be working on cases important to combating oddness, viewing herself as the leader of OSMU. Opal's sister, Olizabeth, is The Shadow. She departed the series after the Season 3 episode "End of the Road" because she is staying with Olizabeth to fix the damage done in Australia.

Agent Omar (Jayce Alexander, season 3): Originally stationed in the Arctic with Opal, he is known to value friendship and connection with his fellow agents, often attempting to mediate or calm the waters among his team, although his tendency to do so can sometimes distract him from the mission at hand. Agent Oswald (Gavin MacIver-Wright, season 3): Before being assigned to the Odd Squad Mobile Unit, Oswald worked as the only employee of the Odd Squad museum in New York City.

Having spent his entire career behind a desk, he is often excited to jump into tasks or cases. Agent Orla (Alyssa Hidalgo, season 3): Orla joins the Odd Squad Mobile Unit after being isolated for 400 years at an ancient Odd Squad headquarters protecting the powerful 44-leaf clover. Because of her separation from society and her history standing guard, she is often unfamiliar with modern inventions and has a tendency to react to situations quickly and without forethought.

Agent Osmeralda (Glee Dango, season 3): Appearing as Esmeralda Kim in early season 3, she often showed up desiring to help but stating she was too busy with various hobbies such as karate or music instrument practice. In "Odd Off the Press," having finally cleared up her schedule, she is brought in to fill the opening left by the departure of Opal. She brings her out-of-the-box thinking skills to the team. Little O (Shazdeh Kapadia, season 3): Formerly Big O's assistant, she takes a position as a substitute for Big O as the head of Odd Squad at the end of "Odd Off the Press."

Agent Ozzie (Alexander Shaw, season 4): An agent at an Odd Squad precinct in the United Kingdom. Agent Orli (Asha Soetan, season 4): An agent who lives and works in Niagara Falls and is called to the United Kingdom Odd Squad precinct to assist in stemming the rising oddness rates. Captain O (Shelly Lagodinsky, season 4): The head of an Odd Squad precinct in the United Kingdom. Agent Onom (Samir Simon-Keegan, season 4): A scientist at an Odd Squad precinct in the United Kingdom. Agent Orwell (Alexander Joseph, season 4): A security agent at an Odd Squad precinct in the United Kingdom.
