Anticlimax Boss: The Hydroclops was built up for most of the first season as being a huge threat by being shown in both the intro and some of the show's segments. In the episode it was set to premiere in, however, it gets roughly a minute of screen-time, and is defeated with one of Oscar's socks.
Author's Saving Throw: In the first few episodes of the series, Ms. O would yell at the agents as a hobby. But as the series progressed, her yelling roles became less and less, making her more likable and relatable. Plus, she would often team up with the agents, and become a victim of oddness, also making her more likable. When you get to know her, she's a pretty nice lady, and being a Management agent is not an easy task.
Jerkass Woobie: Agent Oksanna is this. The real agents get to go on exciting and dangerous adventures, while she's stuck in the kitchen making food for the agents, all day and all night. Poor Oksanna. Agents are quick to accuse her job of being easy, but anytime they have to be her for the day, they are proven wrong.
Ms. O is made of awesome. She can lift a car, defeat any villain, knows all the agents' strategies, and does excellent on cases as well. To say she's a Pintsized Powerhouse is an Understatement.
The sequence of plot twists in the Season 2 finale. Sure some people predicted Otis used to be a villain, but how many of you knew Ohlm would be a villain? Huh? The writers of the program really know their stuff.
Periphery Demographic: The show is garnering many fans who are far past the age of your average PBS Kids viewer, mainly because of the surrealism and clever humor that goes over kids' heads. Carryover of existing older fans of Wild Kratts no doubt helps, as the shows often air consecutively and have similar approaches to conveying STEM information mid-adventure.
The Scrappy: Xena and Xavier. Despite having limited appearances they're both extremely mean-spirited, their laughs are annoying, and one time, they took Olympia's black pen even though they had gold ones because "they made their pens feel better about themselves." Also, they tried to shut down Odd Squad for being over-budget on stuff they needed, while they wasted their money on stuff they bought for themselves they didn't need. All of their appearances are based on them being mean-spirited.
The Tube Operators for showing little to no respect for the agents.In "Trials and Tubulations", they are being self-centered and cared about their happiness more than the agents' safety. In "Trading Places", O'Fynne accuses Olive of being an adult criminal breaking into headquarters. Even when she's proven innocent, she thinks Olive's a criminal. What a jerk.
Ship Tease: The character dynamics and emotional scenes are really well done, so a fan can't be blamed if they have a ship.
Tear Jerker: The scene at the beginning of the movie where Olympia, Otis, Oona, and Ms. O are standing in the middle of a road talking about Odd Squad being shut down, how they're not needed anymore. All four of them look very depressed. Including Olympia and Oona no less. It only gets more depressing in the middle of the film where the scene is revisited and the audience now knows why the scene happened, also it ends with the agents sadly walking back to their homes and Olympia out of all people decided to go last. This scene is without a doubt one of the saddest moments on the show.
If the accompanying conversation wouldn't immediately counteract it, that is...Same goes for the "Saddest Song" above, Soundcheck can't make a properly depressive song.
Trope Overdosed: Dear Odd Squad Troper. If you watch The Movie (or any episode, but especially The Movie) - only hit the pause button on every trope occurance to recover from laughing, otherwise an half hour film would take three. (If you protocol any lampshade, six.)
They Really Can Act: The child stars are impeccable actors, despite their age. The actor for Otis has now snagged an Emmy for this show.
Unintentionally Unsympathetic: Dr. O, Ocean, Oona, and Owen in Olympia's Day. Olympia wanted her own room so she could have a conversation with the Noisemaker, but the other agents didn't care about Olympia's problem, they just wanted to invade her space. Little did they know, they would be crammed in their spaces. Plus when there was a piece left over, Dr. O and Ocean wouldn't let Olympia have that piece, they wanted it for themselves! It's her room guys, let her do what she wants, she isn't stopping you from doing your jobs!
What an Idiot!: What a group of idiots! In Odd Squad: The Movie, townspeople were quick to see Odd Squad agents as evil, just because a villain says they are. Let me repeat, the trusted a stranger they knew for a few days, over the people they knew for decades! Didn't anyone teach these guys about strangers?
The villains of the show love to commit odd crimes around the city hoping not to get caught by Odd Squad You'd expect:, the villains would go in a random order and cover their tracks, Instead, the always travel in specific patterns. As a result, The Odd Squad agents, always figure out the pattern and catch the villains.
Disorder in the Court: Odd Todd and the Shapeshifter have just been exposed for shrinking the town museum framing Olive for it, and Todd leaves Olive with a choice between catching the shrunken town museum and letting him get away, or catching Todd and letting the museum land with a rough thud. You'd expect: Since there were multiple agents in the room, Ms. O would sent one of the agents to capture Todd, and another to catch the town museum before it falls. Instead: When Todd threw the museum in the air, Olive manages to catch the museum, but fails to stop Todd. As a result: The Shapeshifter changed into a getaway jetpack, and Todd got away, but for some reason, none of the agents even cared about it.
Show Me The Money: Okay Oona, you knew you had a collection of unlucky coins in the container, that would bring upon the end of the world as you know it. So why on Earth would you leave the container of coins lying around unprotected, where any fool could accidentally pick one of the coins up?! Answer me that.
World Turned Odd: When Olympia, Otis and Oona accidently altered the day Oprah became a Ms. O, there's a moment of idiocy when Oprah looks at an upside-down 6, and assumed it was 9 Green Street, (rather than 6 Green Street-where she was supposed to go.) Any smart person would find it peculiar that there would be a 9 Green Street on the even-numbered side of the street. If Oprah had noticed that the other buildings on that side where even-numbered, or at least realized a 9 is an upside-down 6. She could've still became a Ms. O, but instead, it took someone pointing this out personally for her to realize this.
Odds and Ends: Sure Big O, give the falseditz control of Odd Squad just because he gave you an action figure. You had hundreds of other worthy candidates, but no, you went with the kid who had never solved any cases within his job.
The Woobie: That poor man with the foot-and-voice problem at the beginning of "No Ifs, And, or Robots" who never got his odd problem fixed, and can't even let them know where he is, or walk towards them.
