- Annoying Laugh: And yet, also strangely endearing. This is also a Shout-Out to his role as Lewis in Revenge of the Nerds.

- Cute but Cacophonic: Loves to sing, and this annoys Danielle.
- Determinator: Goes as far as winning three Nerd-Offs, making it all the way to the Final Two.
- Genki Girl
- Hypocrite: Somewhat. She goes along with Danielle's idea to send Celeste to the Nerd Off, even though herself and Celeste were allied. Later, when Celeste turns against Genevieve, she gets mad at Celeste for "betraying" her when she did the same to her.
From: Somerville, MAAn MIT graduate who specializes in geophysics.
- Cloudcuckoolander: Once you hear that he loves to forage for and eat wild mushrooms, and see him wandering about Nerdvana in the early hours of the morning wearing a space helmet, hiding in bushes and climbing trees... it's difficult not to get this impression of him.
- Reptiles Are Abhorrent: Subverted. His picture shows him having a snake, though he himself isn't a villain at all.
- We Hardly Knew Ye
Ivan Van Norman
From: Torrance, CADeveloper of Tabletop RPGs and a fire dancer.

- Heel–Face Turn
- Hidden Depths: He is rather proficient at dance video games.
Season 2 Contestants
From: Denver, COA library science scholar and trivia expert.
- Action Girlfriend: Brian's lady-friend Liz Thomas is a well-traveled adventure athlete most known for breaking the women’s unsupported speed record on the Appalachian Trail in 2011.
- Badass Beard: Obviously.
- Bewarethe Nice Ones: We all may just want to rub his fuzzy head, but he was happy to keep Zack in as long as possible to crush his opponents.

- Catch Phrase: He has "Mad research skills!" Also he's "Wacky."

From: Waco, TXA structural engineer and MENSA member.
- The Ace
- Black and Nerdy
- Hoist by His Own Petard: He believes that his attempts to play mind games with Zack and Jack just motivated their team to finally win after a long losing streak. He gets eliminated in the Nerd-Off later, with his mind games being a big part of why they nominated him.
- Jerk Ass: In "Nerds To the Rescue," he tries to play mind games with the other team, trying to convince Jack he's angry at him for picking him to be electrocuted in the previous Nerd-Off and constantly trying to annoy or otherwise set off Zack's Hair-Trigger Temper
- The Leader
- The Stoic
- The Strategist
From: Urbana, ILAn M.D./Ph.D. student who specializes in bioengineering.
- Asian and Nerdy
- Bald of Awesome: After he shaved his head for the LARP challenge. Subverted, though, in that he clearly did it to impress the judges... who had no prior knowledge of whether he was bald or not.
- Nice Guy: Seems to be the only person that is generally nice to Zack.
- Karma Houdini: Well, he didn't really deserve much karma for dropping the ring during the challenge and thus preventing "lava" from coming out of their volcano, but with the way the rest of the team acted, you'd think he was bound to go to the Nerd-Off. Instead, he only got one vote (that was shown, at least), and everyone seemed to forget about it.
- To be fair, nobody tried to help him find the ring, and his mistake was overshadowed by Zack's obnoxious behavior.
- Morality Pet: Develops into this for Zack in later episodes.
- Self-Deprecation: On Zack's bad go-karting skills: "An Asian just told you to drive better!"
From: Grayslake, ILVideo game vlogger and Pokémon enthusiast.
- Deadpan Snarker: Zack cuts him off, and his response is just "That's fine, I didn't want to finish anyway..."
- Name's the Same: Not to be confused with Joshua from the first season.
- Unwitting Pawn: To the Purple Team. The Purple Team sent Josh to the Nerd-Off in the hopes that he would lose against Zack, as Zack himself was a detriment to his own team. Josh lost.
From: Pittsburgh, PAA roboticist and puppeteer whose claim includes best-dressed.
From: Greenacres, WAAspiring space explorer whose sight is set on Mars.
- Ambiguously Gay: Essentially states it in the third episode, saying the pirate ship has something for everyone including "tons of cute guys... for Xander".
- She also says in the semifinal episode that she's used to being around guys, but isn't used to the guys paying attention to her, referring to how she's the only girl left in the house.
- For the Evulz: She has first place in the "Nerdio Kart" race, outlapping other people, and still proceeds to crash into them to hinder their progress. Zack fiercely believes she did it on purpose, since after she crashed into him and drove off, she laughed. It's not unlikely.
- Lesbian Jock: Hinted at.
- Never Bareheaded: Almost always seen with her trademark backwards baseball cap. In "Nerdio Kart", she trades it in for a Tron-like racing helmet.
- Trekkie: Is a HUGE Star Trek fan, to the point where she does not have a high opinion of Star Wars.
From: Canton, GAA quad-lingual Japanophile and graduate student.
- Cloudcuckoolander: She was described as being a lot like Luna Lovegood.
- The Ditz

- We Hardly Knew Ye: Lost the nerd-off in episode 1.
Mary Kate Smith
From: Starkville, MSAn aerospace engineering student who gets fired up by rockets.
- Big Beautiful Woman : Has a pretty face and a buxom build.
- Broken Tears: She was not happy and started crying when Josh was eliminated, as she really wanted to see Zack eliminated.
- Fag Hag: Seems to be very close with contestant Xander
- Southern-Fried Genius
From: Milwaukee, WIA chemist and roller derbier who is passionate about vanadium compounds.
- Genre Savvy: In Episode 1, she openly explained in her confessionals that she was not going to reveal her chemistry background in the fears that she would have a target on her back.
- Subverted in the fact that she did tell one person, Zack (in order to set up a two-person alliance), who ultimately told everyone in Episode 2 that she was a chemist due to the science-based task that the teams were participating.
- Hypocritical Humor: Her stated reason for helping Kayla over Jack is that latter's argument's for why the former "shouldn't" be the King of Nerds annoyed her since she doesn't like people proclaiming others "shouldn't" be anything for arbitrary, trivial reasons. Undermining her sentiment was that in a previous confession cam the former also argued that the latter shouldn't be King of Nerds because of a lack of pop culture knowledge.
- Manipulative Bitch: Knows that psychological warfare is the way to win and isn't afraid to prod Zack's ego to get him to do what she wants, as seen in Episode 3.
- Morality Pet: Was this for Zack.
- Team Mom: Was the only member of Midas Touch Attack that was trying to bring the team back together after Zack's outbursts.
- The Starscream: Because of Zack's ego, and the fact that he destroyed the alliance between him and Nicole by revealing her chemistry background, motivated her to send him to the Nerd-Off.
- She's also the only member of Midas Touch Attack to aid Kayla in the finale and that proves to be crucial to the end result.
From: Los Angeles, CAA live-action roleplayer and gamer whose personal motto is "be an open book".
- Camp Gay: A minor example of this.
- Catch Phrase: "Glitterfit"
- The Dandy: Wears multiple costumes throughout the show, especially in the finale
- Gay Best Friend: Is friends with almost everyone on the show, and provides commentary throughout
- Gentle Giant: 6'2"
- Greek Chorus: Gives running commentary on multiple episodes
- Large Ham: Especially during his team's presentation during the challenge in Episode 2.
- Lovable Nerd: Generally loved by the other contestants and fans
- Nice Guy: He's probably the nicest guy on the show.
- Subverted temporarily in his threatening proposal to Kayla to try and remain safe from elimination; he basically tells her that if she votes for him, he'll see to it that something bad happens to her. Though as it turns out, he's not very good at being threatening, because as soon as Kayla points out what he's doing he suddenly gets sheepish and mutters "Awkward..." before proceeding to worry about what might happen.
Zachary "Zack" Storch
From: Minneapolis, MNA fantasy writer and World of Warcraft enthusiast who loves swords and belts.
- Annoying Laugh
- Badass: He survived three Nerd-Offs in a row, the same amount that Genevieve of the previous season went through. The fourth one was his undoing, however.
- Break the Haughty: In the robot dodgeball challenge, Midas Touch Attack seems ready to possibly win, with the challenge being close...and then Zack accidentally drives the robot backwards a bit, getting it stuck on a bar and making it an easy target. Instead of getting angry at the controller or something like a sore loser, he gets mad at himself for screwing up so badly despite being a gamer and his team assuring him for a while beforehand that he could do it. Even the other team acknowledges this, saying to themselves not to rub salt in the wound and staying quiet rather than celebrating like the winning team normally does after these challenges.
- Brilliant, but Lazy: His team accused him of this during the Volcano task, as he would meditate, then nap to help their team.
- The Caligula: As he is the leader, he's pretty much shaping up to be this.
- Can't Hold His Liquor
- Can't Kill You, Still Need You: Titans of Rigel have this feeling towards him; they want him gone as much as Midas Touch Attack does, but they also know the most strategic move is to keep him in the game to cause chaos for Midas Touch Attack, and so force themselves to vote weaker players to face against him to ensure he wins.
- Catch Phrase: "Victory for Sylvanas!"
- The Dog Bites Back: In his eyes, this is what he's doing; getting back at his team for not "appreciating" him.
- Face–Heel Turn: In Nicole's eyes, he pulled one when he revealed her chemistry background, destroying their alliance. To the rest of his team, he pulled one when he didn't seem to help much in the challenge, then had a bit of a rant when he was sent to the Nerd Off.
- Heel–Face Revolving Door: He was nice in the first episode, and in the second until after the challenge. Then he became a jerk, but a dangerous jerk, even to the others on his team, until the preparation for the Nerd Off in the third episode. He made a speech to everyone else (on both teams) and seemed ready to change his ways, but he was still blurring the line between "good" and "bad" until episode 4, where - while still an Insufferable Genius - he seemed to get along with everyone again. But seeing as they still sent him to the Nerd Off that episode, the rest of his team don't believe the change has stuck.
- Hair-Trigger Temper: What triggers some of his more Jerk Ass moments. He has a tendency to go from happy and calm to RAAAAAAAAAGE within a few seconds of something not going his way or him feeling disrespected or unappreciated.
- Insufferable Genius: While he seems to have no idea how to interact with others, his intelligence gives him a legitimate chance at winning.
- Jerk with a Heart of Gold: He seems like he genuinely wants to be friends with the people there, but from his perspective, the other people don't appreciate him. And he did hate going against Nicole, saying he really doesn't want to send her home.
- Small Name, Big Ego: His bragging (and berating) of Josh before the Nerd-Off in Episode 2 certainly did not go over well with his team.
- Sweet Tooth: Zack is often seen with a lollipop in his mouth.
- Token Evil Teammate
Season 3 Contestants
From: Gilbert, ArizonaBookworm.
- Heterosexual Life-Partners: With Heather
From: Los Angeles, CaliforniaMarine biologist.
From: Chicago, IllinoisJeopardy! champion.

- The Stoic
From: Denver, ColoradoNeuroscientist.
From: Oakland, CaliforniaQuizmaster.
- We Hardly Knew Ye: Lost the nerd-off in episode 1.

From: Tempe, ArizonaMathematician.
From: Redwood City, CaliforniaNASA engineer.
From: Denver, ColoradoCompetitive cosplayer.
From: Silver Spring, MarylandLAR Per.
- Butt Monkey: Nobody on his team seems to like him very much.
- The Ditz: His clumsiness messes them up while putting together their Rube-Goldberg Machine, he takes a long time making oars for a boating challenge (and said oars end up falling apart), and in general he doesn't seem too bright.
- Genius Ditz: When he gets voted into the first Nerd-Off, it's about anime. He gets every question right and outright decimates his opponent.
- The Load: Though subverted as, in the episodes where this comes across most apparently and causes him to get ragged on the most, his team still wins.
- He also proves valuable in the cosplay skit challenge thanks to his ability to choreograph fights.
- Nice Guy
From: Springfield, MissouriGamer.
From: Huntington Beach, CaliforniaBrony.
From: Pittsburgh, PennsylvaniaComic book nerd.
- Beware the Nice Ones: He was a Nice Guy in episodes one and two. Then in the third, he learns that he's being unanimously voted into the Nerd Off, even though he had done his job to a tee and Lily was slacking off in favour of flirting with Ben, making her a better one to send home. He held it in as Tranquil Fury until he exploded on Lily in a massive "The Reason You Suck" Speech, which everyone from both teams had to intervene in. Whether this was a Face–Heel Turn or Jerkass Has a Point is up to the viewers, but everyone on both teams seemed to see it as the former.
- Face–Heel Turn: In episode three, as seen under Beware the Nice Ones above. Much like Zack from season two, he went from a Nice Guy to a Token Evil Teammate. Unlike Zack, though, he didn't stick around long enough to really follow through.
- Heel–Face Turn: In the season finale, he atones for his previous actions by choosing to support Lily in the second-to-last Nerd-Off.
