There are Loads and Loads of Characters in this show, and that's just WITHOUT all of the recommended characters.
Blocky (BFDI Ranking: 11th.)
- Ax-Crazy: He has killed the most contestants in the show of all, at 164. In the first episode alone, he debuts trying to kill Bubble, stating he is "just in the mood to hurt someone". He also pulls various cruel pranks on contestants. And then in BFB he breaks Tennis Ball and later Golf Ball both for trying to be in charge.
- The Bus Came Back: Rejoins the game in episode 9.
- Cool Big Bro: As of BFB 2, he seems to act as a sort of brotherly figure to Grassy, who can often be seen sitting on his head.
- Freudian Excuse: Uses one when confronted by Bubble in the first episode.Blocky: I'm just in the mood to hurt someone!
- It's All About Me: Said he is the "star of the show" in episode 17. A flashback shows him being eliminated in episode 4 which shows that this is not the case.
- Jerk Jock: Along with Eraser and Snowball, he is this.
- Jerk with a Heart of Gold: In spite of his aggressiveness and bullying, he calls Golf Ball out for not treating Grassy respectfully.
- Nice, Mean, and In-Between: The mean to Pen's nice and Eraser's in-between. Blocky is one of the most violent characters in the series and while his temper isn't anywhere as bad as Snowball's or Flower's, he's much more prone to killing others than either of them.
- Power Trio: Part of a jock posse along with Pen and Eraser.
- Put on a Bus: He does not recieve enough votes to compete in season 2.
- Took a Level in Kindness: Starting from BFB, he's started to act considerate and less of a bully. Although he wants to do pranks again, he'll have to wait for the recovery centers to be built.
- Would Hit a Girl: He spends much of his time trying to kill Bubble and Ice Cube For the Evulz and once broke Golf Ball in half out of anger.
Bubble (BFDI Rank: 3rd.)
- Back for the Dead: More often than not she'll be revived only to die again shortly after.
- Butt-Monkey: She and Ice Cube are prime examples.
- The Chew Toy: She's one of the most fragile characters in the series and is frequently popped for the amusement of the other contestants.
- Catchphrase: "Yoylecake!".
- The Dog Bites Back: Finally decides to kill Blocky in "Vote Yoylecake" after he attempts to pop her for the umpteenth time, and succeeds in popping him.
- Elmuh Fudd Syndwome: A lot of her vowels are replaced with "oi's".
- Extreme Doormat: She cracks easily when pressured by others. When she tries to stop Lightning from zapping Fanny in BFB 1, Pencil proceeds to mock her for going against the alliances objectives and reminds her of her new bember status, so Bubble gives up and lets him electrocute Fanny.
- Glass Cannon: Shown to be this in Vote Yoylecake, where she somehow pops Blocky.
- Nightmare Face: Pulls off one per YouTuber suggestion in "Gardening Hero".
- Power Trio: With Match and Pencil.
- Killed Off for Real: Flower popped her after destroying all the recovery centers, preventing her from coming back to life.
Puffball Speaker Box: You're not an official BFDI contestant!
- Back from the Dead: She's revived shortly after by Match and Pencil in BFDIA, and while she's killed in one of Bomby's explosions the introduction of the HPRC in the next episode rectifies that. Unfortunately, her death prevents her from competing in the season.
- The Last DJ: In BFB 1, she was strongly against Lightning being used by Match and Pencil to zap unwanted contestants. They then see her as a traitor and reprimand her twice. First, by demoting her to "bember", then, by restating her "bemberhood". This makes Pencil the first eliminated contestant in BFB, after she and Match made their team lose because of their despotism.
- My God, What Have I Done?: She believes Matchs elimination in BFB was her fault since she didnt immediately forgive her for verbally pressuring and demoting her, so she goes around forgiving the other members of iance hoping it wont happen again.
- "The Reason You Suck" Speech: Bubble gives a well deserved one to Flower in "Return of the Hang Glider."Bubble: Flower, I'm tired of this. [...] I mean, I'm tired of your self-centeredness. I'm tired the way you act around us. You know what that's mean? I'm tired of you! [...] Flower, your own popularity is your own fault. Everyone hates you because we can't stand all you talking about yourself!
- They Killed Kenny Again: She is so fragile; she's died at least ninety times; but fortunately there's always a Bubble Recovery Center lying around!
- Token Good Teammate: Bubble is a hell of a lot kinder than Pencil and Match, preferring not to deliberately hurt others' feelings or manipulate them.
- Trademark Favorite Food: She sure loves her Yoylecake.
- Weak, but Skilled: Although she doesn't start out as this, Bubble gradually becomes this trope throughout the series, and makes it through the final challenge in BFDI very quickly, earning her the final immunity ticket.
- What the Hell, Hero?: 3 episodes after the incident from BFB 8, Bubble finally brings herself to stand up to Match and chews her out for acting like Pencil by verbally pressuring and demoting her when she just wanted someone to support her during Pencils absence.
Coiny (BFDI Rank: 16th.) (BFDIA Rank: ??th.)
- Arch-Nemesis: Firey.
- Character Development: He was quite immature in BFDI, mostly thanks to his unfriendly rivalry with Firey. When BFDIA rolls around, he chooses to ignore him when he tries to provoke him and is more of a strategist. By BFB, the two of them have stopped their conflict altogether.
- Flat Character: Back during BFDI, the main extants of his personality were hating Firey and constantly getting into slap battles with him.
- K-I-S-S-I-N-G in a Tree: Does this to Tennis Ball and Golf Ball in the first episode. She disapproves.
- The Leader: Of W.O.A.H Bunch along with Pin.
- Manipulative Bastard: Extorts several members of Team No Name into joining W.O.A.H Bunch.
- Money for Nothing: Being in proximity to Nickel can spawn thousands of dollars within seconds, but the only real use of money the contestants have during their time in BFDI is to bribe each other.
- Reality Warper: If he gets too close to Nickel, they start warping space and creating counless amounts of money from nothing.
- Schemer: In addition to his methods of forcing other contestants to join his team, he has come up with several plans that have saved it from elimination.
- Unfortunate Names: Decides to name his team Wheel Ooze A Hole Bunch, which sounds like "We('ll) lose a whole bunch".
- Undesirable Prize: Let's out a sigh of dissapointment after winning a handful of seeds in BFDIA 2. Averted after they turn out to be Yoyle seeds and the competition of the episode was to make Yoyle-stew.
- Would Rather Suffer: Elects to join the team with only one other member on it rather than the team consisting of every single other contestant after Firey tries to slap him.
- You Are Better Than You Think You Are: When Pin worries about the possibility of Loser being eliminated since her team relied on him so much, Coiny reminds her that hes her right-hand man and she herself has the potential to be a heroic leader. Sadly becomes Harsher in Hindsight since Loser is voted off in the next episode.
David (BFDI Rank: 8th.)
- Catchphrase: "Aw, seriously?". Taken Up to Eleven because it's just about the only thing he says!
- Ambiguously Human: The other contestants claim that David is a human or a man multiple times, not that his stick figure appearance shows it.
- The Friend Nobody Likes: David has been shown multiple times to have even less friends than Spongy. Even if his appearance doesn't appear off-putting to someone, chances are that his personality will alienate them instead.
- The Last of These Is Not Like the Others: Is a stick figure rather then an object.
- Line Boil: Done occasionally while he speaks.
- The Load: Usually refuses to help the rest of BEEP and is generally a prime benefactor in the competitions they lose.
- Non-Standard Character Design: Not an inanimate object and animated slightly differently from the other characters.
- Plot Allergy: He's allergic to sunrises.
- Sixth Ranger: Was BFDI's first mid-season addition as a recommended character.
- Uncanny Valley: David is generally regarded in-universe to be somewhat creepy. He's one of the few contestants to not be an object, Gelatin considers him to be weird and Cloudy almost pukes when he learns David is a man.
- We Hardly Knew Ye: Was only in the first season for 3 episodes, and didn't come back until BFB.
Eraser (BFDI Ranking: 13th.)
- Absurd Phobia: In BFB 1, He is shown to have a fear of pentagons. He freaks out further when he learns that Foldy and Ruby technically are pentagons, too.
- Catchphrase: "Which is...?"
- Jerk Jock: Together with Blocky as one of the "tougher" characters.
- Jerk with a Heart of Gold: A bit rough around the edges figuratively and literally, but he has no problem with being friendly with others most of the time.
- Nice, Mean, and In-Between: The in-between to Pen's nice and Blocky's mean. He shares the latter's jock-ish attitude, and while he's not as cordial as Pen is he's definitely more good with people and less prone to violence than Blocky.
- Power Trio: Part of a trio of jocks along with Blocky and Pen.
- Real Men Wear Pink: Being one of the "tough guy" characters of the show, and he Lampshades this in "Lofty".Snowball: "The balloons were pink! Pink is too girly!"Eraser: "I would disagree. I think pink is quite manly."
Firey (BFDI Rank: 1st.) (BFDIA Rank: ??th.
- Arch-Nemesis: Firey and Coiny loathed each other with a passion until BFB, constantly insulting and slapping one another. Even now, they generally tolerate each other at best as part of The Losers.
- Big Damn Hero: Saves Leafy from being executed by the other contestants in the BFDI finale by swooping in with a hang-glider and whisking her away.
- The Chew Toy: Like Bubble and Ice Cube, he's easy to kill.
- Decoy Protagonist: Despite being the titular character of BFDI's predecessor comic series Total Firey Island, he was eliminated halfway through.
- The Ditz: He can be naive and scatterbrained at times, such as when he fails to realize that Leafy is vulnerable to lava.
- Enemy Mine: Despite his hatred for Coiny, he allowed him to come on Dream Island.
- Kill It with Water: His weakness and why he refuses to take part in the final challenge in "Barriers and Pitfalls" involving scooping up water. Firey will hurt himself if he sweats, will likely die if he can't escape rainfall and being injected with freeze juice is a death sentence as he will be extinguished upon thawing out.
- Narcissist: Implied; given that both his speaker box and Flower's speaker box were the judges of the beauty contest that Firey and Flower won thanks to their respective speaker boxes, and because contestant-created speaker boxes generally have similar personalities to their creators, Firey might have a sliver of narcissism.
- Nice Guy: While his rivalry with Coiny can make him somewhat obnoxious, Firey is a good person through and through.
- Playing with Fire: But of course.
- Screams Like a Little Girl: Whenever he dies or shows signs of his fear of heights, he lets out a very high-pitched scream. Just listen to him.
- Why Did It Have to Be Snakes?: He suffers from aquaphobia and acrophobia.
Flower (BFDI Rank: 4th.)
- Character Development: While still a narcissist, she becomes less aggressive in BFB and has started to befriend Ruby.
- Foul Flower: Is a pretty-looking flower with pink petals, but is most certainly not a pleasant person.
- The Friend Nobody Likes: Disliked by most of the contestants because of her narcissitic personality and constantly screwing over or trying to kill everyone else. The events of the finale firmly cements her status as that, with even reviving her being considered a very bad act. While she's not as hated in BFB, several contestants still want nothing to do with her.
- Hair-Trigger Temper: Its very easy to set her off.
- It's All About Me: Flower is ridiculously self-centered and obsessed with her beauty.
- Jerkass: The only way you can even hope to get respect from Flower is if you suck up to her. She's incredibly petty and will not hesitate to attack or inconvenience others.
- Muscles Are Meaningless: Despite the fact that she's as skinny as David and Dora, she's more than capable of carrying the Master Recovery Center with nothing but her bare hands.
- Narcissist: Big time.
- Non-Standard Character Design: The only non-David contestant to have a stick figure body.
- Pink Means Feminine
- Took a Level in Badass: Inverted. In the Season 1 finale, she's easily able to lift the Master Recovery Center, which is made of metal and is the size of a building, and throw it into an incinerator, but in the first episode of BFB, she struggles to open a jar of cyanide.
- Why Did It Have to Be Snakes?: Shes entomophobic (afraid of insects).
Golf Ball (BFDI Ranking: 17th.) (BFDIA Rank: ??th.)
- Adorkable: Despite her bossiness and mean attitude. Bonus points for being small.
- Birds of a Feather: Is often seen together with Tennis Ball. Both are nerdy and both are sports balls.
- Dark and Troubled Past: Heavily implied to have one of these. A flashback in IDFB shows a white ball (which is presumably her) hiding behind a vase as a spiked club proceeds to smash them. What happened afterwards is currently unknown, but the incident most certainly left her traumatized.
- Giver of Lame Names:
- Accidentally. In episode 9, when Firey wants the name of the new team to be the Squashy Grapes, Golf Ball tells him that Leafy's team is already the Squashy Grapes, and that their team name has to be another name. Because of this, their team name ends up being "Another Name".
- Happens again in BFB 1. Observing that one of the teams has already named themselves, she says that her team needs to have a better name than that. TV takes this literally.
- Huge Guy, Tiny Girl: The tiny girl to Tennis Ball's huge guy.
- Insufferable Genius: Clearly a smart one but she gets egocentric and tactless with her fellow teammates.
- It's All About Me: In BFDIA 5a, she claims that if she's eliminated, her team will be plunged into chaos.Firey: That didn't happen last time.
- The Leader: The self proclaimed one of team No-Name. She also tries to be the leader of A Better Name Than That, but 8-Ball ends up taking over instead, much to her chagrin.
- Older Than They Look: If the BFDI Books of Tips and Tricks is to be believed than she's over a billion years old, but this could likely be overexaggerated.
- Red Oni, Blue Oni: Golf Ball is the loud and bossy Red Oni to Tennis Ball's introverted and calm Blue Oni.
- Reverse Psychology: After her team turned to 8-Ball in BFB, she used this strategy in BFB 3 to manipulate the team into swinging all 50 times.
- The Smart Guy: One of the more intelligent contestants, being obsessed with calculations and knowledge in addition to owning a massive underground laboratory.
- Supervillain Lair: Owns a secret underground factory, complete with its own incinerator.
- Tiny Tyrannical Girl: She may be small, but her words are pure, insufferable authority.
- Vocal Dissonance: Lampshaded by Pen in episode 11.Pen: Golf Ball sounds like a boy, even though she's a girl!
- One of Book's pages also mentions this trope applying to Golf Ball.
Ice Cube (BFDI Rank: 7th.) (BFDIA Rank: ??th.)
- Backstabbing the Alpha Bitch: Having enough of Book and her being apathetic towards her teammates, Ice Cube leaves Bleh so she'll be happier.
- The Chew Toy: Is right behind Bubble as the most frequently killed off contestant in the series.
- The Friend Nobody Likes: Match, Pencil and Bubble clearly dislike her and constantly treat her like dirt yet she wants nothing more than to be a part of their friend group.
- Kill It with Fire: Her ultimate weakness.
- Screw This, I'm Outta Here!: Decides to switch teams due to Book's tyranny, and eventually ends up joining iance. She is still technically a member of Bleh, however.
- Stealth Pun: Being a vengeful ice cube, she may be a walking pun on the saying "revenge is best served cold."
- Stock Audio Clip: Past episode 4, every single line of dialogue she has is recycled. This is taken to some impressive lengths given that she was in almost every episode of BFDI. This record was broken in BFDIA 5, and Lampshaded in BFB 1.
- The Dog Bites Back: She generally won't give up an opportunity to enact vengeance against someone.
- They Killed Kenny Again: Vulnerable to melting and shattering, but good for there's always an Ice Cube Recovery Center lying around!
Leafy (BFDI Rank: 2nd.)
- Berserk Button: Do not reject her kindness.
- Beware the Nice Ones: In the BFDI finale, she stole Dream Island out of rage of being 2nd place and Firey allowing everyone but her to come into it, causing everyone sans Firey to hate her. After fleeing to Yoyleland, she develops a murderous demeanor, trying to kill Needle, Gelatin, and Puffball after they arrive.
- Control Freak: Becomes this in BFB, obsessively micromanaging her teammates and giving them jobs during challenges.
- FaceHeel Turn: Turns on everyone in the BFDI finale out of selfishness and then becomes a recurring antagonist in BFDIA and IDFB. By the time BFB rolls around, she's trying to be cordial again.
- The Friend Nobody Likes: The events of BFDI's finale and BFDIA have made Leafy quite unpopular among the other objects. When she is voted back into BFB in "Get to the Top in 500 Steps", her former team just backs away from her slowly.
- Genki Girl: BFB shows that she can be very energetic and talkative when shes at her best.
- Informed Kindness: While she is a nice character, she does have several mean moments. However, her list of niceness states that she's eight levels above "reality-ending nice." All the other contestants, asides from Bubble, are way below the "mean" level, despite many of them being Leafy's friends.
- Innocently Insensitive:
- In spite of her selfish tendencies and somewhat controlling nature, Leafy is unaware of these flaws and believes shes genuinely trying to do good. She eventually realizes these flaws got her eliminated, so she apologizes to the viewers for her behavior in her rejoining audition.
- After finding out she rejoined the game, Leafy starts crying Tears of Joy and unintentionally uses Braceletys drawing for Ice Cube as a tissue not long after shes asked to give it to her.
- It's All About Me: Leafy, despite her overall friendliness, is actually quite selfish, evident by the way she lashes out at Bubble when she unintentionally rejects her acts of kindness. When disagreed with, she can become defensive and try to prove that her opinion is the superior one. This comes to a head in BFDI's finale when she buys Dream Island from the Announcer when Firey allows everyone but her in it due to her displeasure with his ferris wheel in the previous episode.
- Kill It with Fire: Gets burned to death at least once. It doesnt help that, in later episodes, she spends much of her time with Firey.
- Knife Nut: After being slapped by Needle in Yoyleland, she tries to murder her, Gelatin and Puffball with knives.
- Larynx Dissonance: Due to her deep, boyish voice in later episodes, fans often mistake her for a male.
- Nice Girl: She was initially very helpful to her fellow contestants (Ice Cube especially) and got along with most of them, which makes her shift in personality jarring from the BFDI finale onwards.
- Non-Indicative Name: Is actually a football in a leaf costume, as revealed in "Return of the Hang Glider."
- Tomboy: Much more boyish compared to characters like Flower and Match.
Match (BFDI Ranking: 14th.) (BFDIA Rank: 19th.)
- Alpha Bitch: She and Pencil love to boss around their alliance and teammates, especially Bubble.
- Freudian Excuse: When trying to reason with Bubble in BFB 11, she claims the reason she treated her so harshly during the eighth challenge was so she could act as a placeholder for Pencil during her absence and set an example so the other members of iance wouldnt screw up. Bubble doesnt immediately forgive her.
- Heterosexual Life-Partners: With Pencil.
- Hypocrite: Fanny accuses her of being this, as she berated Bubble for the entirety of Episode 8s challenge just because she didnt know the answers to a majority of the questions, while Match herself was no better.
- Jerkass: Incredibly judgemental towards people she dislikes - Spongy especially. Even her own friends aren't safe from her abuse.
- Jerkass Has a Point: In BFB 8, despite her verbally pressuring Bubble for most of the challenge, she rightfully points out that iance should not be up for elimination due to Stapys cheating.
- Like Is, Like, a Comma: Inserts the word like in her sentences almost every time she talks. Taken Up to Eleven during her elimination in BFDI, which actually provides the page quote.Match: Youve got to win this for, like, like, like, like, the both of us!
- Valley Girl
Needle (BFDI Ranking: 19th.) (BFDIA Rank: ??th.)
- Berserk Button: Dont call her Needy, or shell slap you.
- Lethal Chef: Added so much yeast to a cake that it grew into a bubble the size of a star and achieved nuclear fusion several weeks later, plunging Earth into a torrent of solar wind.
- Lightning Bruiser: Very fast on her feet as shown in BFB 11, and can slap hard enough to launch others into the sky. She's also got the toughness to back it up, as at one point, she got knocked into space, popped a star-sized yeast bubble, and fell straight back to Earth with not a scratch on her.
- Nice Girl: Shes very soft-spoken when she isnt slapping others.
Pen (BFDI Ranking: 12th.)
- Breaking the Fourth Wall: Addresses and thanks the viewers in the 4th anniversary video for BFDI.
- Buffy Speak: Refers to the Announcer occasionally as "Announcer Thing".
- Cheaters Never Prosper: Despite being one of the kindest characters on the show, he ends up cheating his way through challenges three times in the first season. To elaborate, he and Blocky find the test answers in episode 3, and he buys cake and part of a taco from Leafy in episodes 4 and 15 respectively. The last instance is what led to his elimination.
- Competition Freak: Out of all the contestants, he seems to be the most focused on winning Dream Island.
- Crouching Moron, Hidden Badass: Although he can be dim-witted, he's the reason Death P.A.C.T. got 1st place in most of the challenges.
- Heroic BSoD: Goes through a short one in BFB 1 when his friends end up on separate teams from him.
- Keet: In stark contrast to Eraser, Pen is very cheerful and positive.
- Nice Guy: Much friendlier compared to Eraser, Blocky, and Snowball. He smiles a lot more often and shows the most concern out of everyone when Flower destroys all of the recovery centers.
- Nice Hat: His cap functions as this.
- Nice, Mean, and In-Between: The nice to Blocky's mean and Eraser's in-between. He may be a jock like them, but he's friendlier than both of them combined.
- Sensitive Guy and Manly Man: The sensitive guy to Eraser/Blocky/Snowball's manly men. Blocky and Snowball are aggressive and find entertainment in beating people up and Eraser is grumpy and doesnt show much emotion. Pen, on the other hand, is much sweeter and more emotional, serving as the groups Morality Pet of sorts and being part of a team with pacifist goals in BFB.
- Terrible Artist: At least in the eyes of Four, X, and the recommended characters, since his drawing of Four led to his teams loss in BFB 4.X: You are a disgrace to the entire art community, and the entire world would rejoice if you never touched a piece of paper again, EVER!
Pencil (BFDI Ranking: 9th.) (BFDIA Rank: ??th.)
- The Alliance: With Match and Bubble. Ruby gets added in BFDIA, while Book and Ice Cube are alternates. When Book and Ice Cube left in BFB, the name was reduced to "iance" as suggested by Snowball and done by Fanny.
- Alpha Bitch: Has shades of this, being the leader of a mostly faithful Girl Posse, very selfish, and generally rude towards others, even her alliance members. Unlike most examples of this trope, shes not as blatantly girly.
- Cool People Rebel Against Authority: When Golf Ball makes Team No-Name promise to never switch to W.O.A.H Bunch, Pencil refuses and instead decides to start her own team with her alliance as team members.
- Does Not Like Men: Implied; she reacts with disgust when a group of males enter Eternal Algebra Class, which initially consisted of only girls.
- Girl Posse: Pencil's alliance consists entirely of girls, and she and Match generally subject the other four members to their whims with little care.EWWWW, ITS A BUNCH OF BOYS!
- Heterosexual Life-Partners: With Match.
- Hypocrite: Consistently accuses Golf Ball of being a bossy-bot. Pencil herself isnt any better.
- Jerkass: Shes very bossy and quite egotistical. By the time BFB airs, shes even worse than before, ordering Lightning to electrocute anyone she dislikes and demoting Bubble to a bember when she tries to prevent him from zapping Fanny. This led to her elimination in the following episode.
- Mad Libs Dialogue: Usually in her rejoining auditions:(X) yeah yeah yeah, (Y) yeah yeah yeah, so I can win the contest, so I can win the contest!
- Nice Guy: She was this before she became a Jerkass. She would get mad when someone killed her friends and didn't get voted for because of this trope.
- Valley Girl: Not as easily noticeable as it is with Match, but she definitely has shades of this trope. She says "OMG" more often than other contestants, and occasionally says "like," but not as frequently as Match.
Pin (BFDI Ranking: 20th.) (BFDIA Rank: ??th.)
- An Arm and a Leg: Loses all four of her limbs in "Get in the Van" as revenge by Puffball for accidentally killing her Speaker Box. She gets new limbs made out of her pigment by IDFB 1, though.
- Heroic BSoD: During BFBs sixth challenge, she worries about the possibility of Loser being eliminated since the team relied on him so much, and frets if they can do things independently if hes gone. Thankfully, Coiny is there to give her a pep talk.
- Hidden Depths: Pin is an excellent pattisere and seems to have a fondness for gardening, as shes instantly able to recognize what Yoyle seeds look like, finds it cute when she notices Fries trying to grow potatoes (and tries to befriend him in the process), and carried some blueberry seeds with her in BFB 1.
- Super Strength: Pin is by far the strongest character next to Loser. As shown in Zeeky Boogy Doog, she can effortlessly shake the Eiffel Tower as if it's made of papier-mâché.
- Supreme Chef: Wins the cake-baking contest in "Sweet Tooth" by making a cake replica of Flower, and baked the cake used for "Enter the Exit"'s Cake at Stake which X describes as being made by someone very talented. It's because of this that she's chosen to pipe Four's essence into his usual shape to revive him.
- Took a Level in Kindness: Started off as a mean, selfish bitch. From BFDIA on, shes a lot more cheerful and outgoing, even developing a close friendship with Coiny.
Rocky (BFDI Ranking: 6th.) (BFDIA Rank: ??th.)
- Breath Weapon: Rocky's barf has a lot of uses, making effective projectiles or even being able to propel him into the air.
- Flat Character: Aside from the swiss army barf, there really isn't that much about Rocky.
- The Friend Nobody Likes: Despite his mostly pacific attitude, Rocky has abrasive relationships with most contestants due to his abrasive vomit.
- Perpetual Smiler: Almost always wears a huge smile on his face.
- The Voiceless: He has had very few speaking roles in the series, with most of them being in the 1st episode and one being in the 19th episode. The only sound he makes other than his signature "Bulleh!" is a high-pitched squeak. Double-subverted. Vocally reacting to Balloony's death in BFB 12 is what gives him away as BEEP's imposter.
- Vomit Indiscretion Shot: Whenever Rocky's around, expect this to happen at least Once an Episode (outside of BFDIA, that is).
Snowball (BFDI Ranking: 15th.)
- Berserk Button: When Golf Ball claims he has a tiny brain, he gets pissed.
- But for Me, It Was Tuesday: Has no clue why Fanny would be pissed off at him during Cake At Stake in BFB 12 even though he nearly completely decapitated her in the previous episode because she told him to just let Flower do the challenge to not invoke her wrath.
- Dumb Muscle: One of the physically strongest characters, but he cant even remember his own name.
- Everyone Has Standards: Despite his aggressive and rude demeanor, he refuses to beat up Bubble when Flower asks him to. He's got no problem popping her whenever he feels like it, though.
- Fantastic Racism: Shows consistent prejudice against armless objects, thinking they are weaker than those with arms. Fanny seems to be an exception since he praises her for her abrasive personality.
- Grievous Harm with a Body: Threw Rocky at Golf Ball in one instance.
- Jerk Jock: Along with Blocky and Eraser. While they at least have some shreds of decency, Snowball is just a thorough jerkass.
- The Load: It's easier to count the number of times Snowball has contributed to challenges or at least tried to rather than the times he's hindered his teams.
- Took a Level in Kindness: Starting in BFB 13, he's become friendlier than usual, having normal conversations with his team and even helping save Bubble's life.
- Static Character: He's known for being aggressive and angry, and never changes at all.
- Would Hit a Girl: He tried to hit Golf Ball two times, once slammed Fanny onto the ground and broke her, and has killed Bubble multiple times.
Spongy (BFDI Ranking: 5th.) (BFDIA Rank: ??th.)
- Dumb Muscle: Spongy's far from being smart, but his size means he has the brawn to make up for it.
- The Friend Nobody Likes: Almost everybody else hates Spongy because of his size and bad hygiene, even though he's almost always nothing but kind.
- Gentle Giant: By far the largest contestant in the show, and one of the kindest.
- Hidden Depths: Spongy wants to do a lot more than his overly large size lets him do and is a bit of a thrill seeker despite his soft demeanor, including skydiving, playing table tennis and ping-pong, tightrope walking, flying hot air balloons, flying planes, and...sailing airplanes?
- Iron Butt Monkey: Another one of the characters prone to getting abuse both verbal and physical from the others, Spongy is on the receiving end of quite a bit of slapstick throughout most of his time on the show. However, there's not much that can actually kill him unlike the series' other Butt Monkeys, with his only known weaknesses being lava and Spikes of Doom.
- Karma Houdini: He caused the whole lava outbreak in BFB 14, and then refused to save his teammates for petty reasons, yet he's one of the survivors by the end of the episode.
- Mighty Glacier: Abundant in strength (he is said to be good at throwing in episode 5 of BFDIA, and even helps carry a bag of money the others can't carry in the same episode), but his vast weight makes it hard for him to maneuver or perform tasks the other contestants could easily perform. He's only fast enough to back several trips to the bread basket and back in BFDI 14, but he manages to carry so many loaves at a time that he's able to win the challenge and rejoin. He is only beaten in the slowness department by Rocky.
- Nice Guy: Spongy usually likes everyone, even the contestants who frequently get ostracised by others for petty reasons.
- Prone to Tears: It doesn't take much to upset him.
- Supreme Chef: Is shown to be a downplayed version of this in the episode Vomitaco, where he makes a taco that the majority of the eliminated contestants like despite it having been made with his feet.
- Your Size May Vary: In several instances, Spongy is large enough to serve as a platform for others, while in others, he's only somewhat larger than the next largest contestant, Tennis Ball.
- Justified because sponges are able to expand in water and shrink when dried, albeit it is a bit exaggerated.
Teardrop (BFDI Ranking: 18th.) (BFDIA Rank: 20th.)
- Hidden Depths: Teardrop is hinted to be fairly intelligent, as she managed to pass the test in Episode 3, with 15 points.
- Out of Focus: Her early eliminations in both BFDI and BFDIA in combination with her inability to speak haven't given her much of a chance to show much characterisation. She's survived BFB for nearly the time she played in both prior seasons combined, but the sheer number of characters doesn't help.
- Pint-Sized Powerhouse: Sent Woody flying into the air with just a kick in the first episode.
- The Quiet One: Teardrop is apparently unable to talk, a trait the other contestants love to abuse.
Tennis Ball (BFDI Ranking: 10th.) (BFDIA Rank: ??th.)
- Adorkable: A given, being softer than Golf Ball yet still nerdy at the same time.
- Berserk Button: Do not call him clumsy.
- Birds of a Feather: Is often seen together with Golf Ball. Both are nerdy and both are sports balls.
- Gentle Giant: One of the largest characters with a nice and friendly attitude.
- Huge Guy, Tiny Girl: The huge guy to Golf Ball's tiny girl.
- The Klutz: His large size and lack of arms make him quite clumsy, something the Announcer loves to tease him over. When him and Leafy are tied to be eliminated and must jump over a cliff to survive, it's him who messes up and bounces off.
- Morality Pet: To Golf Ball, although shes not evil nor a complete Jerkass, shes just very bossy. Hes one of the only contestants shes consistently friendly with.
- Only Sane Man: On several occasions, Tennis Ball has shown to be much more rational than the other contestants. Best expressed in BFDI 14 when the Announcer throws his marble collection (worth 15 bonus points) into a pool of hydrochloric acid, as rather than mindlessly jumping in like the other contestants, Tennis Ball uses his magnet to retrieve the marbles, something the other contestants wouldn't have thought of.
- Red Oni, Blue Oni: The calm and rational blue to Golf Ball's easily angered and loud red.
Woody (BFDI Ranking: 21st.)
- Abhorrent Admirer: He is this to Teardrop in Episode 1, albeit briefly, because a single kick from her sends him flying.
- Absurd Phobia: He is afraid of everything—he even dies temporarily after seeing the color grey.
- Comical Overreacting: Something as small as sticking a fork in his face tends to garner the same reaction from Woody as if he saw someone get brutally maimed in front of him.
- Hard Head: In the first episode, a piece of his head gets chipped off after hitting Rocky, it stays that way for the rest of the series, but doesn't seem to hurt him or even bother him.
- Lovable Coward: Averted in BFDI, as almost no one likes him due to his panophobia. Played straight in BFB, however, due to having his panophobia toned down significantly and becoming more cheerful and useful in challenges.
- Minor Injury Overreaction: When he gets chipped in the first episode, he screams loud enough that Eraser and Pen can hear it from some distance away.
- Prone to Tears: Pretty much everything causes him to have a major freakout.
- Scars Are Forever: He's retained the chip on the top of his head he received in the first episode for the entire series, regardless of dying and being recovered, and spent half of BFB's current runtime being dyed orange by Four and dented by Bell.
- Screams Like a Little Girl
- Shrinking Violet: Quite the shy type.
- The Unintelligible: Has only spoken one coherent sentence during his entire time on the show, in BFB 2.Roboty! (panting) Tell me where you aaaare!!! Can you hear me? We need you!!!!
- Took a Level in Cheerfulness: As of BFB, hes less of a wimp than in BFDI and smiles a lot more often. Its adorable.
Bomby (BFDIA Rank: ??th.)
- Ascended Extra: Started out as a cameo character in episodes 9, 11, 17, 18 and 22 (the first recommended character to appear in the series no less) and finally became a full on character in season 2.
- Berserk Button: Whatever you do, don't take his banana, or he'll (figuratively) explode on you.
- Catchphrase: "Ohnofireyyoulitmyfuse!"
- Cartoon Bomb: His design is based off it.
- The Chew Toy: His other teammates have taken advantage of his explosive tendencies to win a challenge on several occasions. Gelatin has attempted to do this numerous times in BFB and is always quickly shot down by the rest of Team Ice Cube.
- Death Is Cheap: He'll panic when his fuse is lit or someone makes him explode, but as long as he's able to be recovered he doesn't care much about dying all that often.
- Fruit of the Loon: Often holds a banana, but is never seen eating it. Taking it from him makes him angry, though.
- Join or Die: Unwillingly joins team W.O.A.H. Bunch after Coiny threatens to ignite him with Firey.
- Motor Mouth: Has a tendency to talk really fast.
- Out of Focus: Suffers this a lot in BFDIA and BFB.
- Promoted to Playable: In BFDIA.
- The Quiet One: He doesn't speak most of the time, as shown in BFB. Even Fries lampshaded his silentness.
- Running Gag: Can often be seen eating a slice of cake and a banana, and usually explodes at least once per episode. This stopped in BFB as his teammates do their best to prevent that.
- Stuff Blowing Up: Thanks to his debut, these gags are now possible. During BFDIA, the others exploited this for all it was worth.
- Trademark Favorite Food: Often holds a banana and cake slice.
- Ungrateful Bastard: He's more concerned about how Black Hole destroyed his banana in BFB 11 when Flower knocks him off the staircase rather than how he prevented him from impacting the ground and exploding. At the very least, he's died so many times that he doesn't care about his life being saved anymore.
Book (BFDIA Rank: ??th.)
- Academic Alpha Bitch: Showed this starting from BFB 3. She bullies Taco out of belief that she abandoned her and doesn't show compassion for Saw's "eight" condition. Lollipop lampshaded this behavior in BFB 13 after being tired with her.
- Berserk Button: Do not call her "well-read".
- Cool Big Sis: Acts like one towards Ice Cube.
- Cool People Rebel Against Authority: Leaves Team No-Name to form a new team after seeing the other members of Pencil's alliance do so.
- The Ditz: As of BFB, unlike her in BFDIA.
- She blatantly ignored Taco's jawbreaker on her team's swingset, as well as her being surrounded by the pieces of the broken jawbreaker, and even her boasting that she freed herself, leaving Book to believe that she abandoned the team, which stuck to her ever since.
- She ignored the twinkle on earth as her team latches onto ABNTT's rocket in episode 6, and even commented on the view down there. She didn't even notice the twinkle catching onto her team, or even herself. The only time when she ever reacted was when Taco dropped off to get the twinkle back down.
- In the next episode, she used the ship's communicator dish as a dipping plate for her chips, which made it a lot harder for ABNTT to connect with Remote.
- Exactly What It Says on the Tin: As of BFB, when referring to the cover title on her first two designs in season 1.
- Flanderization: Her personality quickly devolved to having a scathing hatred of Taco after the events of BFB 3.
- Great Big Book of Everything: Book is many things - a dictionary, a BFDI tips and tricks guide, an HPHPRCC manual, etc.
- Heel Realization: When Gaty tells Book to look up herself in herself, she does, and her definition literally changes to "MEAN" before her eyes. It is then she realizes she is being irrational.
- He Who Fights Monsters: After leaving Pencil's alliance in BFB for being too unhealthy, she also left her sanity and intelligence there.
- Jack-of-All-Trades: Functions as a Dictionary, a Journal, an HPHPRCC manual and an IDFB books of tips and tricks all in one.
- Jerkass Ball: Places a firm grip on it after Taco goes missing and she ends up believing that she abandoned the team. After the third challenge, she regularly badmouths Taco and is much more aggressive, and her behavior only gets worse until Gaty manages to talk her out of it.
- Nerdy Bully: She acts like this towards Taco, believing she abandoned her team and will take any chance to bring her down. Another factor is that she's intelligent and is a manual.
- Nice Girl: Much more sensible compared to Pencil and Match.
- Not So Above It All: While she may be one of the kinder and more rational characters on the show, she ends up believing that Taco abandoned her teammates out of spite, solely because they completed the first challenge very slowly. After Taco is freed, Book begins to detest her for that very reason, even though it clearly isnt true.
- Sudden Name Change: Goes from Dictionary in BFDI to Book in BFDIA.
- Took a Level in Dumbass: Was once the voice of reason for Freesmart, now nothing but a bumbling, stubborn, and ignorant loony with red ink for Taco.
- Took a Level in Jerkass: After believing Taco abandoned the team, Book develops a massive hatred for her, constantly talking shit about her, jumping to conclusions more often, and having more emotional outbursts, a very far cry from her usual softspoken Nice Girl attitude. It's not until BFB 13 she starts seeing the error of her ways.
- Ungrateful Bastard: In BFB 6, Taco let go and fell back to earth just to get the twinkle off of the moon. Book still sees this as counting as abandoning the team. Lampshaded by Lollipop in BFB 12.Lollipop: I happen to know that this fishy friend of ours is the only reason we survived episode 6. It was because of her strategy.
Dora (BFDIA Rank: 21st.)
- Arch-Nemesis: She apparently tried to killed David a lot of times.
- Bizarre Taste in Food: Her diet consists almost entirely of islands.
- Expy: Based on Dora The Explorer.Puffball Speaker Box: Dora, why don't you go explore the TLC?
- Gratuitous Spanish: Dora's pre-BFB dialogue was made of very fast Spanish, often accompanied by English subtitles running nearly as fast.Estoy muy contento de que Fries me haya dado la pala y, con ella, la capacidad de cavar. Sé que si puedo cavar, ¡puedo crear islas! Y como las islas son mi único alimento, crear islas es muy importante para mí. Amo tanto las islas que he escrito mi propia canción isleña. ¿Te gustaría escucharlo? No importa, no me importa tu opinión. Lo voy a cantar de todos modos. Dice: "¡Islas, islas! ¡Yum, yum yum! ¡Islas, islas! ¡Chomp. Islands! ¡Son tan deliciosas! ¡Dame islas ahora! ¡Dame! ¡Dame dame, dame! ¡Dame! ¡Islas! ¡Yum! ¡Islas. "Gloop! Gulp! Lala! Islands". ¿Entonces, qué te parece? No importa, no me importa tu opinión. Sé que tú, siendo parcial contra nosotros, comedores de islas, dirás que lo odias. Pero los amantes de las islas sabemos que todas las canciones que escribimos son maravillosas. Mis dos cosas favoritas en el mundo son las islas y las canciones. Mis dos cosas menos favoritas son tú y David. David no es mi hermano. Ni siquiera está relacionado conmigo. He intentado matarlo muchas veces, pero todos mis intentos han fallado miserablemente. La mayoría de mis fracasos son el resultado del horrendo "David Cloner". Olvidé decirte que el David Cloner ocupa el tercer lugar en mi lista de menos favoritos. De todos modos, de vuelta a las islas. Me gustan las islas Ellos son buenos. ¡Qué bien, quiero cantar mi canción otra vez! "¡Islas, islas! ¡Yum, yum yum! ¡Islas, islas! ¡Chomp. Islands! ¡Son tan deliciosas! ¡Dame islas ahora! ¡Dame! ¡Dame dame, dame! ¡Dame! ¡Islas! ¡Yum! ¡Islas! Gulp! Lala! Islands ".
- The Last of These Is Not Like the Others: Like David, she's a stick figure not an object.
- Lightning Bruiser: Exaggerated to insane extremes; she's capable of withstanding the heat of lava, can break open a giant jawbreaker with little effort, and can run so fast that she can knock others out of her way (given she has the time to charge up).
- Line Boil: Done occasionally while she speaks.
- Made of Iron: Somehow manages to survive running through an oven and swimming through molten lava-and completely undamaged!
- Non-Standard Character Design: Not an inanimate object and animated slightly differently from the other characters.
- Strange Minds Think Alike: Whatever the hell she says most of the time, it's definitely in a manner that politely convinces Four to stop screwing around.
- Trademark Favorite Food: Appears to be Islands.
- The Unintelligible: Not that one would even be remotely able to understand her original hyperspeed Spanish, but as of BFB her voice is just a bunch of Animal Crossing syllables.
- We Hardly Knew Ye: During BFDIA, she only lasted three episodes and only had one speaking role.
Donut (BFDIA Rank 22nd.)
- Early Installment Character-Design Difference: Originally looked a lot more cheerful, and lacked arms.
- Hostile Show Takeover: Not exactly hostile, since he only became the host because of Golf Balls plan to get rid of Four and X, who ended up getting sealed inside of him.
- Jerk with a Heart of Gold: While irritable and somewhat crabby, Donut is very considerate and respectful of others, such as when he shows distaste towards the others climbing Bell without her consent. This is more noticeable in BFB since he was eliminated early in BFDIA.
- No Sense of Humor: Tends to not take others' jokes well, especially if they don't make any sense as seen when Tennis Ball and Golf Ball give each other shifty eyebrows other the supposed innuendo in saying that Donut has the factor of Four within him.
- Noodle Incident: What sort of horrifying things has he discovered about Bomby?
- Power Incontinence: If he tries to resurrect someone Four-style, he ends up mutilating them.
- Took a Level in Kindness: Hes much less of a Jerkass in BFB. Best shown in BFB 3, when he tries to motivate his teammates to win the third challenge. Even though his team loses, he shows genuine concern for an injured Bomby and even brings him a first-aid kit with bandages. Hes come a long way since BFDIA.
- Sealed Inside a Person-Shaped Can: Four and X get sealed inside him in BFB 6 after Golf Ball's devious plan to multiply Four by Donut succeeds. X actually escaped offscreen at the last minute, and Firey extracts Four's essence from Donut's body several episodes later.
- Straight Man and Wise Guy: Has this dynamic with Gelatin, being the Straight Man to his Wise Guy.
- Reality Warper: Nowhere near the extent of Four, but absorbing him still allows him to casually break most laws of physics.
Fries (BFDIA Rank: ??th.)
- Catchphrase: "Get digging, X, the ingredients are probably underground".
- Characterization Marches On: He was originally a cannibal who was always seen carrying around a box of fries with him. So far, this has never come up in BFDIA, although he did eat Spongy in episode 4.note
- Early Installment Character-Design Difference: In the original BFDI he had had a B on the front of his box resembling the McDonald's golden arches. This was replaced in BFDIA with a pair of yellow stripes.
- Grumpy Bear: He's almost never in a good mood.
- Hypocrite: Lambasts others (particularly Gelatin) for trying to eat his fries, but originally debuted carrying and eating a smaller packet of fries. Then again, he has stated that he will die if he runs out of fries for an extended period of time.
- No Sympathy: Calls Teardrop lazy for not spinning the prize wheel despite the fact that she was killed by poison in the previous episode.
- Running Gag: The other contestants will constantly eat his fries, much to his annoyance.
- Surrounded by Idiots: When with Gelatin and Firey.
- Would Hit a Girl: Has no problem slapping Book back in the premiere of BFDIA when he remarked that he couldn't stand her cover.
Gelatin (BFDIA Rank: ??th.)
- Cloudcuckoolander: Develops a strange obsession with forks in BFB.
- Combat Pragmatist: In BFB, he has a habit of trying to use Bomby to sabotage the challenges and make his team win. This strategy makes his team lose in BFB 3. Occasionally subverted, such as in BFB 9 and offscreen in 11, where he suggested to use Bomby to do the challenge instead of for the usual foul play.
- Idiot Ball: In episode 5, he randomly ties his legs with Firey's twice.
- Ditzy Genius: Is able to make an antidote for poisoning and is the inventor of the freeze juice, but he is stupid enough to tie his legs with Firey twice and keeps shoving his teammates off Puffball when they are flying on her due to perceived space issues.
- Manchild: Becomes this in BFB. Donut questions why he acts like a six-year old, to which Gelatin replies that he is six. He was either being sarcastic or telling the truth.
- Straight Man and Wise Guy: Has this dynamic with Donut, being the Wise Guy to his Straight Man.
- Took a Level in Dumbass: Starts off as calm and laid-back. Ends up becoming an immature weirdo by BFDIA 5 and develops an odd thing for forks by BFB.
Nickel (BFDIA Rank: ??th.)
- Adaptational Nice Guy: In stark contrast to the Nickel on Inanimate Insanity, who is a cynical, uncaring Jerkass. This Nickel, however, is much nicer, less sarcastic (in BFB, he doesnt seem to understand when its being used), and is willing to get himself involved in his teammates weirdness.
- Early Installment Character-Design Difference: In Season 1 he had arms, yet they were removed during Season 2. Although in his first season 1 appearance he was armless. Later on he got arm to hold up a sign
- Expy: Is also a character on Inanimate Insanity.
- Large Ham: In BFB.Nickel: HOLY ROLY POLY CRAWLING IN GUACAMOLE!
- Money for Nothing: Being in proximity to Coiny can spawn thousands of dollars within seconds, but the only real use of money the contestants have during their time in BFDI is to bribe each other.
- Reality Warper: If he gets too close to Coiny, they start warping space and creating counless amounts of money from nothing.
- Sarcasm-Blind: In contrast to his Inanimate Insanity foil, who is a Deadpan Snarker to the max.
Puffball (BFDIA Rank: 18th.)
- Auto-Tune: Her voice is heavily vocoded.
- Berserk Button: Does not like being called Puffy. W.O.A.H. Bunch tries to abuse it in BFDIA 5d to blackmail her into carrying them to Yoyleland, but it doesn't work and she just revives Gelatin to get him to make them shut up.Pencil: feeling the personal speaker box Puffball won as a prize Hey, it's so fuzzy!
Puffball Speaker Box: Stop that!
Pencil: It even sounds like you, Puffy!
Puffball: Don't call me Puffy, but I'm not going to slap you, 'cause I'm nice.
Pencil: No, you're not gonna slap me because you don't have arms.
- Cloud Cuckoo Lander: Pink, flashes rainbows when talking, can fly and says random things in a vocoded voice.
- Everything's Better with Rainbows: She's capable of vomiting them.
- Fatal Flaw: Greed - she is very prone to losing her composure when introduced to the prospect of rewards. Downplayed a bit in BFB 9, where she hogs the cake slices that were meant for Foldy and Bell.
- It's All About Me: Puffball will not miss an opportunity to indulge in greed even at her teammate's expense.
- Jerkass Ball: She sabotages her teams chances of winning just so she can win the prize when they get put up for elimination. This scores her enough dislikes to be eliminated.
- Killed Offscreen: She's eliminated in between the events of BFDIA 5 and IDFB 1 but it's never actually shown.
- Size Shifter: Can enlarge herself enough to carry everyone for air transport.
Ruby (BFDIA Rank: ??th.)
- Camera Obscurer: Implied in IDFB episode "Welcome Back" to have done this every day for three years because she doesn't know what a lens cap is.
- The Cutie: She's very perky and sweet, so that's why she's this trope.
- The Ditz: More obvious than other members of Pencil's Alliance.
- Genki Girl: One of the liveliest characters on the show. A non-canon video even has Tennis Ball tell her to lay off the sugar.
- Not So Different: After Pencil and Match were eliminated, she takes command of iance and starts ordering her teammates, just like Pencil.
- Prone to Tears: Definitely not as shy as most examples of this trope, but shes very sensitive and bursts into tears when Pencil yells at her in BFDIA 5C.
- Sixth Ranger: The fourth member in Pencil's Alliance.
- Too Dumb to Live: Jumps down the Yoyle Needy to catch the falling Pencil, citing that it's a quicker way to the ground than the staircase, and predictably shatters on impact.
Yellow Face (BFDIA Rank: ??th.)
- Ascended Extra: Initially a promoter in BFDI's occasional commercials but becomes a contestant in BFDIA.
- Catchphrase: "So yeah, BUY NOW!" and "YAY!"
- Driven to Suicide: Is capable of dying on command, something W.O.A.H. Bunch needs to do when he gets stuck in FreeSmart's glue trail.
- Everything's Better with Rainbows: His favorite screen.
- Expy: Possibly of various commercial salesman like Billy Mays.
- Fantastic Racism: "Oh my gosh, you do not know anything! You're... PURPLE!"
- Large Ham
- Non-Standard Character Design: His outlines are much thinner and his speech animations are cruder, reminiscent of the style that would be used to animate Four and X come BFB in 2017.
- Cruel and Unusual Death: His elimination. After hes voted off the show, Donut traps him in between the moon and the Earth, then turns the gravity back on so the moon slowly crushes him to death. Thankfully, its not permanent.
- Cannot Convey Sarcasm: In BFB 4 8-Ball reveals that every time he said the opposite of what Golf Ball told their team to do, it was supposed to be in a sarcastic tone.
- Commander Contrarian: Frequently tells the rest of his team to do the opposite of what Golf Ball tells them to do, but he's actually trying to be sarcastic and means no malice to her.
- The Leader: Replaces Golf Ball as the team leader after leading his team to victory in BFB 1.
- Machine Monotone: Speaks in this tone of voice, making him come off as emotionless and overly stoic. This makes him unable to use sarcasm properly, since whenever he told his team to do the opposite of whatever Golf Ball said, they thought he was being sincere.
- Mighty Glacier: 8-Ball can painlessly break open a giant jawbreaker simply by chomping down on it. However, due to having no limbs, he has to roll around to move.
- Not So Stoic: At the end of BFB 4, he drops his monotone voice and breaks down crying while explaining his failure to convey sarcasm to Golf Ball.
- Suspiciously Specific Denial: Constantly denies having a favorite number. Its become a Catchphrase of sorts.
- The Chew Toy: Surprisingly averted; he's one of the few "fragile" characters who isn't abused by the others, and is instead seen as a fatherly figure to his team.
- Cool Big Bro: Seems to act like this to Rocky, who he refers to as little one.
- The Heart: A friendly guy who loves to help out his teammates when he can and is respected greatly in return. Cloudy laments in BFB 10 that being deceased through the previous three episodes has had a major impact on their team and their success.
- Insistent Terminology: He refers to vomit as "salt and vinegar", but as an endearing slang term. Would vomit really be that appetizing into first place?
- Team Dad: Acts a lot like this, often scolding his teammates for being uncooperative or reckless, but hes a very Nice Guy overall and cares a lot for Rocky.
- Arch-Nemesis: Lollipop.
- Berserk Button: She hates when people don't take her seriously because of what she is.
- Cool Big Sis: Serves as a sort of older sister figure to the other members of Team Ice Cube.
- The Dog Bites Back: After 8 episodes, in "Questions Answered," Barf Bag finally stands up to Lollipop's abuse of her.Barf Bag: (speaking to Donut) Sorry, my reflexes are too slow.Lollipop: (pops up) It's the barf molecules.Barf Bag: Shut it, LolliPOOP!
- The Friend Nobody Likes: Downplayed. Although not unpopular and hated, Barf Bag is constantly judged by her peers due to her appearance and overall species. Despite that, she keeps trying to prove herself to them, especially Lollipop.
- Nice Girl: Generally friendly and empathetic as long as you don't get on her bad side.
- Not So Above It All: Although being wise than most contestants, she didn't hesitate to climb Bell's string, which Donut was against.
- The Smart Girl: Actually pretty intelligent and rational-minded compared to...about ninety-percent of the cast, but no one takes her seriously solely because she's a barf bag and the vomit is apparently messing with her brain.
- Tomboyish Voice: Which leads to some viewers mistaking her for a male. In fact, when she first spoke in BFDI, her voice was actually masculine and manly.
- Nice Girl: Despite her rebelling against Golf Ball, she's nothing but kind to others and acts like a big sister figure to Grassy.
- "Oh, Crap!" Smile: Her reaction to getting caught as the fake Rocky in BFB 12.Uh, I mean...bull-ehh?....
- Wrench Wench: In BFB 7, she mentions that she spent much of her time "inspecting" Robot Flower and uses her to try and control Remote.
- Ambiguously Gay: Seems to enjoy Taco's flirting in BFB 6, and is visibly flustered by it.
- Berserk Button: Don't climb her string.
- Rejected Apology: In the stinger of BFB 10, she confirms to Taco that she holds a grudge against her for using her to get the twinkle off of the moon, and never gets over it.
- Tomboy and Girly Girl: The girly girl to Tacos tomboy.
- Ambiguous Disorder: According to Remote, his sense of hearing isnt too great.Remote: Black holes aren't known for their sense of hearing.
- Artistic License Physics: He has complete control over his gravity field. Zig-zagged whenever anyone gets dangerously close to his event horizon.
- Dark Is Not Evil: Hes easily one of the most (if not the most) powerful characters on the show, and could cause a massive amount of destruction if he wanted to. Despite this, hes surprisingly laid-back and does not use his powers for evil, meaning he has excellent self-control.
- Eldritch Abomination: Is a black hole.
- Reality Warper: In BFB 3, he states that he can "pull like there's no tomorrow", then explains it by saying that he can warp space-time so hard that there will be no tomorrow.
- The Generic Guy: Almost-comically the most-normal character in the entire cast, with no real quirks aside from his powers.
- Gravity Master: Black Hole's immense gravity has been very useful in regards to both preventing death and keeping Death P.A.C.T. safe during challenges. He can even slingshot falling contestants back into the sky by staying the right distance away from them so that they are affected by his pull, but not enough to be sucked into him.
- Mellow Fellow: He's a very calm, rational and friendly individual.
- Nice Guy: He's a pretty chill guy and wants to prevent death and control his powers.
- Unrealistic Black Hole: He has a gender identity, a personality, and can talk like the rest of the cast.
- Catchphrase: "And X is dead!"
- Captain Obvious: Frequently says certain characters are dead, after they are shown dying ahead of time.
- The Ditz: A bit of an airhead, likely because Bottle is an empty bottle literally filled with air.
- Literally Shattered Lives: An inevitable result of a combination of being in a show where characters die frequently and being made of thin glass. Tree is unwilling to shatter her to free himself after somehow getting jammed in her during BFB 7, but Taco is perfectly fine with doing so when her mind is injected into his body five episodes later.
- The Pirates Who Don't Do Anything: She was never shown to be actively saving lives, even when right next to her. Lampshaded by Remote and Liy after her two Captain Obvious announcements:
- Ascended Fangirl: She was originally a minor recommended character who supported and idolized Ice Cube before she joined the game officially in BFB. Unfortunately, she misses out on the chance to be in the same team as her at the last minute.
- Favouritism Flip Flop: When she arrived at EXIT, and is informed of Loser's lying, she says that she doesn't hate him, until 8-ball states that Ice Cube hates Loser, and she changed her mind and says that Loser sucks after all.
- Genki Girl: Incredibly hyperactive and loud, especially when Ice Cube is involved.
- Lipstick Lesbian: After being eliminated, a picture of her and Ice Cube surrounded by hearts is featured among one of the teams' art projects.
- The Millstone: She outright admits that she'd prefer to help Bleh win challenges because it's the team Ice Cube is on.
- No Indoor Voice: She yells a lot.
- We Hardly Knew Ye: Currently holds the record for the least amount of episodes participated in at four, as she was the first of BFB's newcomers to be eliminated.
- Luminescent Blush: Does this a lot.
- Masculine Girl, Feminine Boy: The feminine boy to Pie's masculine girl. Is voiced by a female, however.
- Shrinking Violet: One of the shyest and most easily frightened contestants, frequently relying on Loser for emotional support.
- Arch-Enemy: Seems to be Four, as he stands up to him more often than the other contestants and is frequently screeched at in return. Fours to-do list in BFB 10 even lists Kill Clock.
- Comical Overreacting: When someone tries to touch his clock hands.Don't you ticking dare touch my clock hands!
- Collector of the Strange: Has a convenient pile of junk lying around.
- Elmuh Fudd Syndwome: Has a weird accent that swaps letter sounds.
- Mood-Swinger: Becomes a rain cloud when sad, becomes a thunderstorm when angry.
- Stealth Pun: He is a cumulus cloud who also happens to be The Collector.
- What the Hell Is That Accent?: He speaks with an accent switching voiced and unvoiced consonants note
- The Ingenue: Sweet, shy, and very kindhearted.
- Not So Above It All: Believes Barf Bag's brain is infected with Barf Molecules like the others and was unfairly harsh to Clock when he made the team lose in BFB 6 despite Clock helping the team more than she did.
- Grumpy Bear: Shes always in a bad mood.
- Hates Everyone Equally: Fanny hates everyone and everything with no real reasoning and the only explanation she gives is in her speech to Clock.Clock: Why would you hate me? I'm just trying to stand up for Teardrop!Fanny: Because self-improvement only occurs when we acknowledge that our own behaviors are far from perfect, and, dare I say, worthy of hate.
- Hidden Depths: If this line from her is anything to go by, Fanny also hates herself.Bracelety: You're worthy of hate!Fanny: Yes, I am!
- Jerk with a Heart of Gold:
- Grouchy as she is, she goes out of her way to try and comfort Bubble in BFB 8s post-credits scene.
- Overall, Fanny seems to have a strong sense of morality, giving Loser a What the Hell, Hero? rant for lying (albeit harmlessly) and expressing hatred towards Match for her verbal pressure towards Bubble and hypocritical actions.
- Made of Iron: BFB 12 reveals that Fanny survived her supposed decapitation from the previous episode, and isn't shown to have trouble functioning at all.
- Perpetual Frowner: Shes almost always seen with a massive frown on her face.
- Tomboy: Mostly when compared to her teammates.
- Bratty Half-Pint: He can be very insensitive and obnoxious at his worst, which is demonstrated in BFB 12, when he badmouths his teammates throughout the entire challenge.
- Inexplicably Identical Individuals: Is literally just a smaller version of Firey. Whether or not theyre related is currently unknown.
- Out of Focus: He, like Naily, had barely had any focus in the series until BFB 12.
- Took a Level in Jerkass: BFB 12 really showed his jerk attitude. As a character not really shown to do anything before, this might as well be an Establishing Character Moment.
- Beware the Nice Ones: When she finds out that Match recorded footage of Stapy cheating in BFB 8's quiz and subsequently that he was eliminated, she decides to avenge him by getting into a fight with Flower to make sure iance loses the stair-climbing contest.
- Nice Girl: Sweet and kind, though she has a rivalry with Liy and a major grudge against iance for getting Stapy eliminated.
- Not Quite Flight: Foldy can take advantage of her thin and light body to glide on the wind.
- Power Trio: With Marker and Stapy.
- Revenge Before Reason: Tries to make sure iance will lose the contest as a payback for getting her best friend Stapy eliminated, even if it means risking her own team's chance of winning.
- Jerk with a Heart of Gold: She can be grumpy and passive-aggressive, but she ultimately means well and is one of the few members of her team who doesn't hate Taco. She even tries to get Book to put herself back together as her Jerkass behavior starts to get worse.
- Larynx Dissonance: Has a masculine voice but is female. Her voice actor is female too, oddly enough.
- Not So Above It All: Despite being one of the rational contestants, she had no problem boasting to Four that they couldn't eliminate her because she's never been up for elimination. Four understandably blasts her in return.
- Only Sane Man: One of the very few members of her team who doesnt get involved in the Taco drama. Shes also more straightforward compared to them.
- Passive-Aggressive Kombat: Gaty is very grumpy and usually complains during challenges despite not doing anything herself.
- Smug Snake: She had no problem boasting that she couldn't be eliminated.
- Token Good Teammate: The only person on Bleh apart from Dora who doesn't badmouth Taco at all following the events of BFB 3 when she finally escapes from the jawbreaker she was trapped in for weeks.
- Cheerful Child: Is always excited and and happy.
- Third-Person Person: This trope applies to him most of the time.Grassy: "Grassy needs respect!"
- Blind Obedience: Almost immediately obeys the orders of Pencil and Match without arguing back.
- Harmless Electrocution: Zig-zagged. Whenever he electrocutes another contestant, it only results in stunning them, but he mentions that hes killed dozens when Snowball recruits him.
- Shock and Awe: Naturally.
- Vocal Dissonance: Has an oddly high and wavy voice despite being a guy.
- Arch-Nemesis: Shes involved in a feud with Foldy and Stapy for a currently unexplained reason.
- Dude, Where's My Respect?: She does not take her elimination well, complaining that out of everyone in Death P.A.C.T., she saved the most lives.
- Fantastic Racism: Believes she knows better than Clock because she's a light switch and he isn't.
- Innocently Insensitive: She doesnt seem to know that her actions tend to hurt others, such as when she uses Ice Cube to forcefully get Teardrop to speak and when she climbs Bell without her consent. This is further characterized by her innocent-sounding voice.
- Insane Troll Logic: How does she try to get Teardrop to talk? She holds her mouth open while another participant wiggles her vocal cords so they make noise. It doesnt work.
- Jerk with a Heart of Gold: While she isnt exactly the friendliest, she does want to help prevent death and create trust among the contestants.
- Manipulative Bitch: She forces Ice Cube to help her make Teardrop talk against her will, even though Ice Cube herself isnt willing to do so.
- Token Evil Teammate: Parodied on Death P.A.C.T. Although she wants to save lives, she killed someone before, and is the only one to do so. Unlike Black Hole, Pen, and Remote's kills, hers was on purpose.
- What the Hell, Hero?: She gives this to her team when she's eliminated, due to how she saved the most lives and doesn't get support.
- Arch-Nemesis: Barf Bag.
- Insufferable Genius: Very much so. Shes intelligent enough to create fork repellent, but shes arrogant and prone to judging others based on their appearance.
- Jerkass: Shes very judgemental and rude, insulting Barf Bag by claiming that the vomit molecules inside of her have infected her brain and therefore makes her stupid, and tries to make her to look like she doesn't care about the issue by forcefully wiggling her arms when she presents proof that her intelligence isn't being affected.
- Jerk with a Heart of Gold: Unlike the rest of her team, Lollipop has realized the truth behind Tacos supposed betrayal and sticks up for her in BFB 12.
- Jerk with a Heart of Jerk: During BFB 4, the only time that this invention and its antics were ever onscreen, The fork repellent is actually made to make the forks attracted to Four. She sprayed them on Death P.A.C.T because they're the primary target for Gelatin to throw forks at. When Four was hit with them, they blamed it on Gelatin. During the challenge, the repellant went as far as making all of the forks attracted to Four, distracting Death P.A.C.T from the challenge into protecting Four from them, until the last minute. She might be trying to take advantage of that team's overly pacifist and protective nature. They eventually lost the challenge, but for a different reason.
- Nerdy Bully: She is as intelligent as arrogant and judgmental, and frequently gets into fights with Barf Bag, just because she is a barf bag.
- The Nicknamer: Refers to her fellow contestants with nicknames-examples include Bagel Brain for Donut, Sport Globules for Tennis Ball and Golf Ball, and Little Gray Zig-zag for Saw.
- 100% Adoration Rating: Every character seems to love him. Becomes 0% Approval Rating when it turns out he was lying about poppers.
- The Ace: He's probably a Parody Stu given how much he is idolized, but Loser is by far the most skilled member of his team.
- Broken Pedestal: Lying about loving to play with poppers when he was younger seems to have soured most of the contestants' opinion of him.
- Fate Worse than Death: At the end of BFB 7, he is trapped in an inverted jawbreaker and flying in space. Four rescues him in BFB 10.
- The Heart: Seems to be this among the contestants. This is evident after his elimination, when several of them begin to go rogue during the episodes challenge.
- Ironic Name: Treated with respect with most of the cast, despite his name. At least until BFB 7.
- Living Emotional Crutch: While a lot of characters rely on him for support, Cake relies on him the most and has trouble doing a lot of things without him, which is evident after his elimination.
- Non-Indicative Name: One of the few characters who isnt named after what object they are. Loser is a golden cube, previously used in the first season to represent members of a losing team.
- Pintsized Powerhouse: Loser is one of the smaller contestants, but in BFB 1, he lifts a large basket that is trapping part of his team.
- Beware the Silly Ones: He's a dirt eater for sure, but he ate Lollipop out of anger for her not being Foldy.
- Cassandra Truth: Desperately tries to convince Firey Jr. that he summoned Four by shaping his hand into a four during a game of rock paper scissors, but his only witnesses to the event are either eliminated and busy having tea with Pillow (Stapy) or dead (Foldy).
- Cloudcuckoolander: Even zanier than most other contestants. He enjoys playing bizarre games like "Toss the Dirt," somehow manages to make all sorts of impossible hand shapes while playing RockPaperScissors with Foldy and Stapy - with one even managing to turn into Four's body, and believes that vampires exist.
- Elmuh Fudd Syndwome: Swaps the sound "r" with "w", just like the Trope Namer.
- Extreme Omnivore: He eats dirt in BFB 9.
- Power Trio: With Foldy and Stapy.
- Cat Smile: Frequently sports one.
- Out of Focus: She, like Firey Jr., had barely had any focus in the series until BFB 12.
- Pungeon Master: Frequently makes puns, usually variations on "Nailed it!"
- Ungrateful Bastard: Accused of being one by Barf Bag and Firey Jr, when she said Loser deserved his elimination.
- Character Tics: Has a tendency to sit in odd positions whenever she can.
- Larynx Dissonance: Has an oddly masculine voice.
- Made of Explodium: Is made of blueberries, which are explosive in the BFDI universe.
- Masculine Girl, Feminine Boy: The masculine girl to Cake's feminine boy.
- Mellow Fellow: Very laid-back, but also very apathetic.
- Cloudcuckoolander: If her arm-fluttering theory is anything to go by. She also licks Lollipop while the other contestants are trying to bring back Four, claiming she was just hungry.
- The Ditz: Visually represented in the beginning of BFB 7 where a popper made a bulge in her, showing just how empty that she is.
- Know-Nothing Know-It-All: Downplayed; shes not an idiot, but she is a smart-alec, claiming that Teardrop was making an arm-fluttering gesture to show how little she cared for Eggy and giving an in-depth explanation on how the gesture worked.
- Competition Freak: In Episode 7, in order to help her pacifistic team win, she impulsively sends A Better Name than That and Bleh a bomb after being remote controlled by Robot Flower and nearly making Death P.A.C.T. lose against her own will.
- Overall, Remote seems to be far more focused on winning than on her team's goal of preventing death.
- Hoist by Their Own Petard: When Robot Flower cuts the signal that connect's her team's rocket to Remote, the bomb that Remote had set up and attempted to send them returns and causes her to explode.
- Shoot the Dog: Despite being a member of the team whose primary goal is to put an end to the contestants' constant run-ins with death, she attempts to send A Better Name Than That a bomb when they use Robot Flower to possess her and move the Liar Ball from the moon. Understandably, Pie and Black Hole aren't happy with her attempted murder.
- Synthetic Voice Actor
- Jerk with a Heart of Gold: Threatens the viewers into voting for her and purposely sabotages Blocky in BFB 1, but later sacrifices her team's chance of winning in order to save them and Bleh from Remote's bomb in BFB 6.
- The Load: Is largely useless in challenges due to a lack of limbs, snail-tier mobility, and inability to speak human language, not at all helped by him constantly teleporting off to parts unknown during challenges.
- Offscreen Teleportation: Twice in BFB. The first instance is during the second challenge when he tries to get away from Leafys obsessive micromanaging, and the second is after hes eliminated.
- Terse Talker: Because of how long that each letter is in audio length in morse code, his dialogue needs to be as short as possible to stay around as long as normal speech.
- The Unintelligible: Double subverted - Roboty talks in morse code, but none of the other contestants can understand it.
- The Chew Toy: Managed to run through the world's largest oven and retrieve a basket in "Getting Teardrop To Talk", resulting in her handle being burnt off and the deaths of everyone else on her team but Dora. When 8-Ball is crushed into fumes by the moon, she accidentally inhales him and becomes unable to speak sentences without ending them in "eight", not at all a help in a trivia-based challenge.
- Everyone Has Standards: Despite her hating Taco like the rest of her team, she felt sad when she thought Taco died in "The Liar Ball You Don't Want", showing that she doesn't hate her completely.
- Verbal Tic: After inhaling 8-Balls fumes, she ends up gaining a habit of randomly saying eight. She tries to fix it, but ends up regularly shouting "eight".
- What Happened to the Mouse?: She mysterious went missing as of BFB 9, and didn't appear again until BFB 13, having gone to fix her Verbal Tic.
- Arch-Enemy: Stapy and Liy mutually hate each other for reasons unknown.
- Berserk Button: While normally very laid-back, he gets incredibly pissed when Fries accidentally kills Foldy in BFB 1.
- Cheaters Never Prosper: He uses a fake buzzer to put iance up for elimination in BFB 8, but Match catches footage of him cheating and Donut promptly puts Free Food up for elimination instead. This is what got him eliminated.
- Escalating War: Triggers a massive feud between iance and Free Food when he decides to spend the entirety of BFB 8's challenge constructing a false buzzer to cheat his way to victory at iance's expense, only thwarted by Match showing Donut the footage. Stapy is elimimated, Foldy seeks revenge on iance upon doing so and prevents Flower from completing BFB 11's challenge, and then Ruby unfolds her to get back at her team being UFE.
- Everyone Has Standards: Although he loves playing dirt games with Marker, like Toss the Dirt, he draws the line when it comes to Eat the Dirt.
- Mighty Glacier: Admits to being one of the heaviest contestants. In order to move, he has to leap around due to his weight and lack of legs.
- Never My Fault: If he does something wrong, intentionally or otherwise, expect him to blame it on his stapler instincts, even if it has nothing to do with mistaken stapling or anything.
- Power Trio: With Foldy and Marker.
- And I Must Scream: As a result of Nickel telling David to stop licking the last jawbreaker after BEEP loses, Taco is trapped in said jawbreaker for several weeks. Sound can pass into it but not out of it, leaving her at the mercy of her team with no way to inform them of her whereabouts, and is forced to eat her own fillings to avoid starvation.
- Determinator: She makes her teammates run through a scorching desert, the worlds largest oven, and molten lava just to retrieve a basket for the first challenge. She dies in the process, but it saves them from elimination in the end.
- The Friend Nobody Likes: She remains trapped in a jawbreaker for the entirety of Episode 3s challenge, but her teammates are unable to hear her pleas and come to the conclusion that she either died or abandoned them. Once shes finally freed, they end up showing massive contempt towards her.
- No Respect Guy: Taco's been the reason Bleh have survived most of the challenges, but nobody gives her any gratitude for anything she does whatsoever because they think she willingly abandoned them when nobody released her from her jawbreaker in BFB 2.
- Trauma Conga Line: Things have not been going well for her. Stuck in a jawbreaker without anyone to free her, forced to listen to hear teammates lament her presumed death/abandoning the team, shunned by them once shes freed, and scorned by Bell when she tries to apologize for using her in the sixth challenge.
- Tomboy and Girly Girl: The tomboy to Bells girly girl.
- Tomboyish Voice: She has a fairly deep-sounding voice, which fits with her stubborn and somewhat reckless personality.
- Hypocrite: In "Today's Very Special Episode", he tells Pen to solve a problem on his own rather than going and asking Black Hole, saying that a true winner does his research. Immediately after, Tree asks Black Hole to solve the same problem Pen wanted to solve when a manual shows that's what he should do.
- Only Sane Man: Is the most serious of his team, and is one of the few objects that doesn't have completely twisted logic.
- Ascended Extra: He doesn't get enough votes to join BFDIA, but Firey says he should be the host since he resembles the Announcer and is spared from the LOL as a result.
- Dreadful Musician: His first Cake at Stake song isn't anything to write home about, but the second one is an earsplitting mess.
- The Faceless: Rarely uses his screen to project his face, usually displaying footage of the surrounding area to help his team with challenges or expressing emotions through video clips.
- Synthetic Voice Actor: On the very rare occasion he speaks. It seems to have a Scottish accent.
- Chuck Cunningham Syndrome: Aside from three cameos in BFDIA, he is completely absent from BFDIA, IDFB and BFB.
- Didn't Think This Through: A lot of challenges of his are easily cheated on by contestants with abilities that can be used to do so, and some of these challenges even hinder contestants with very glaring disadvantages.
- Jerkass: Consistantly subjects the contestants to cruel challenges, toys with them to amuse himself and traps the eliminated ones in a cramped metal box for months.
- Jerk with a Heart of Jerk: At the end of "Insectophobe's Nightmare 2", he reveals he spent his own money on the recovery centers for contestants... so he could enjoy killing them again.
- Karma Houdini: After all he's done, culminating in rendering the competition pointless by selling Dream Island to Leafy after Firey bans her from it, he escapes back to his home planet with other speaker boxes and with millions of dollars in his pockets without as much as a slap on the wrist.
- Synthetic Voice Actor
Firey Speaker Box
- The Bus Came Back: Firey pulls him out to serve as a replacement host when the Puffball Speaker Box is slain.
- Karmic Death: Decides to chop up Donut's body to use as a cake for BFDIA 5A. Donut returns the favor shortly after he becomes BFB's host minus the recovery.
Flower Speaker Box
- Killed Off for Real: By her own creator via a bowling ball on accident.
- We Hardly Knew Ye: Only lives for a couple of episodes before another of Flower's awry revenge schemes kills her.
Puffball Speaker Box
- Auto-Tune: Like her owner.
- Everything's Better with Rainbows: Cycles through the color spectrum when talking much more than Puffball does. Not everything is better with rainbows, however, if you're currently barfing up gallons of multicolored bodily fluids after having a large knife lodged into your back.
- Killed Off for Real: Accidentally murdered by Pin when a knife thrown by her at Leafy is dodged by everyone else in its trajectory.
- Fantastic Racism: Claims Yellow Face was this after he said "Oh my gosh, you do not know anything! You're... PURPLE!"
- We Hardly Knew Ye: Was only in Insectphobe's Nightmare 2 for a brief commercial.
- Whatever Happened to the Mouse?: Hasn't been seen after Yellow Face ate him.
Recommended Characters (ones that never joined the game and ether made a cameo or didn't get enough votes)
- Recurring Extra: They may not be in the game but are just as useful as cameos, especially crowd shots.
- Astral Projection: He can project his body into his inner dimension to interact with eliminated contestants in EXIT. This does however have the side effect of leaving him near immobile in the outside world.
- Ax-Crazy: Very, very prone to inflicting horrendous trauma, physical or otherwise, on anyone and everyone.
- Berserk Button:
- Do not throw things at him, particularly forks. Gelatin learned this the hard way.
- Dont criticize him either. In BFB 2, when the other contestants yell at him for refusing to recover the dead contestants, he gets frustrated and explains the second challenge in a very angry tone. He also prepares to kill Nickel just because he objected to one of his comments.
- Don't say that four isn't the most important number or not your favorite one.
- Brown Note: Four screams to stun contestants when they attempt to provoke a conversation with or aggravate him.
- Can't Take Criticism: Whenever a contestant tries to protest against his behavior or talks back to him, Four will either screech at them, deform them, or flat-out ignore them until he decides to oblige to their complaints.Four: I think someone is criticizing me. I don't like criticism!
- Comedic Sociopathy: Four's failure to build relationships and just be nice to everyone is often made fun of.
- Easily Forgiven: Despite insulting and physically harming X throughout the first 5 episodes, X doesnt seem to harbor any malice towards him and remains as loyal to him as ever.
- Eldritch Abomination: He can deform, revive or absorb characters, warp matter with ease or freely create it, and managed to somehow shrink Black Hole by crushing him with his hand. Overall, he's generally invulnerable outside of physical math equations. If Balloony's knowledge of EXIT is any indication, his inner dimension may also function as an afterlife.
- Genius Loci: There's a clasroom inside his body that he absorbs eliminated contestants into and then projects himself inside to teach them algebra.
- Jerkass: He has little to no concern for the contestants well-being. When he deforms Pin in BFB 1, he refuses to recover her, and when the alive contestants demand he recover all the characters who died, he ignores them until he decides to give in.
- Kick the Dog: Does this a lot, such as when he mutilates Pin solely because he can and rubs it in Coinys face. He also tends to berate X, such as mocking him for not knowing his value or claiming that nobody noticed his absence in BFB 3 (which makes him cry).
- No Biological Sex: While he uses male pronouns, Word of God is that Four is sexless and he states in BFB 10 that "they don't have (gender) where he's from".
- Off-Model: Appears more like a poorly-animated doodle, being cruder than the likes of Yellow Face.
- Pre Ass Kicking One Liner: Before he blasts Gelatin with lasers in BFB 3 and brings him to the brink of death, he says, "It's time." Subverted with BFB 6, as before he can fry Nickel with his Wave Motion Gun, he is multiplied by Donut thanks to A Better Name Than That's plan.
- Reality Warper: Frequently creates things out of nothing, can mutilate others with a touch, has the power to shoot lasers with cause videogame-style damage, can revive people by shooting them out of his arms and can fuse with other mathematical symbol-like people in manners akin to equations. Inside him is a pocket dimension containing a classroom where he can project himself inside to teach eliminated (and possibly deceased) contestants algebra.
- Sanity Slippage: Over the series, Four's mannerisms slowly get more absurd to the point that, in BFB 6, Golf Ball hatches a successful plan to take out Four and X after Four's destruction gets more and more ruthless. He appears to be toning down after being revived by Pin and Firey in BFB 10, luckily.
- Took a Level in Kindness: Sincerely thanks Pin for reviving him in BFB 10 and happily reciprocates X's feelings when he says that he missed him along with praising him for doing a good job hosting the show while he was gone.
- Wave Motion Gun: Can fire this from his hands at any victim who has offended him.
- Butt-Monkey: Forced into being Four's co-host for BFB. Hes also a common victim of his screeching and insults.
- Disney Death: Is revealed to have escaped the incident that killed Four in BFB 9, having run away before he could be absorbed into Donut. Just touching him was enough to begin the multiplication process.
- Nice Guy: Especially when compared to Four. He tries his best to be considerate of the contestants' feelings and give them nice cakes when he holds Cake at Stake unlike the other hosts who tend to reward odd or inedible things, and comforts Cloudy when he's miserable over Balloony's death and inability to be revived, something he also apoligizes for not being capable of doing.
- Not So Above It All: While he may be sweeter than Four, he ruthlessly insults Pens artistic ability in BFB 5, calling him a disgrace to the entire art community.
- Off-Model: Appears more like a doodle, being cruder than the likes of Yellow Face.
- Prone to Tears: Bursts into tears in BFB 3 when Four says that no one noticed he was gone.
- Shrinking Violet: Without Four, X is shown to be extremely shy when asked to host in Episode 9. He has trouble speaking up, and is so shy that he fails to explain the rules of the episode's challenge clearly (or at least to Team BEEP).
- Big Ol' Eyebrows: Oh yes.
- Chuck Cunningham Syndrome: She hasn't been seen since IDFB, although she appear as a recommended character in Four Goes To Far.
- Eldritch Abomination: The other contestants seem to treat her like a Slender Man-esque horror. She phases into anybody she captures, but the effects are unknown.
- Evil Counterpart: She's either this to Leafy or an evil split personality.
- Genius Loci: Has a entire population of objects on her.
- Obviously Evil: Red color, Big Ol' Eyebrows, and a disturbing angry expression. She is even called "Evil Leafy".
- Silent Antagonist: Never talks. This is what makes her so scary.
- Teleport Spam: Rather than walking, she constantly teleports to move around.
- Thousand-Yard Stare: Which only adds to her creepiness.
- The Quiet One: Has never spoken.
- Ascended Extra: Went from being a background character made by a fan, to having a somewhat imporant role in Welcome Back. They even saved iance from elimination in Questions Answered, despite not being on their team, or even a contestant.
- Ambiguous Gender: is yet to be reffered with male or female pronouns.
- Living Prop: It looks like a camera, acts like a camera, and make noises like a camera. Has also never spoken.
