XFOHV: Hasn't been seen on camera since the last 14 years, but we have some idea about their personality. She seems to be pretty energetic, when she's doing something they like (playing catch/being in videos) they're active, if she dislikes something (Five not picking up the ball/Being in number 13) they're vocal about it. They may have anger issues, as he threatens to beat up Five for not picking up a ball; she also writes in newspapers. 
TPOT: trapped in 4, chooses to stay.

A silly number from BFDI whose rather impulsive

XFOHV: Despite being energetic and seeming optimistic, Fourteen is a cannibal. They enjoy eating the skin of others and playing pranks. They're basically insane or smthng idk, he's currently in jail and has to update the subcount.

A silly number from BFDI who eats skin

XFOHV: Sad because they didn't know his value (it's 7, but X says his value changes everyday), gets along well with the other numbers (except Three).
BFB: Is Four's Co-host. X is shown to be much more kind, considerate, and understanding then Four; all contestants seem to respect/care about him. Being loyal to Four, X started off as dependent and nervous on their own but has managed to develop into a more confident host. In summary, X is generally friendly. They like bowls I guess.
TPOT: Chef

XFOHV: Optimistic and kind, Ten is friends with everyone in the Equation-Playground, being seen as a 'role-model' for other numbers. He enjoys spotlight (but isn't egocentric), keylime pie, playing sports, and helping his friends. Ten is generally accepting towards everyone, but their best friend would be Eight. Their only enemy is Fourteen, who ate his skin. 

A silly number from BFDI who is loved by all

XFOHV: Six's personality varies; They seem vengeful/violent on one side, wanting to kick Seven (potential arch-enemy) and Eight (friends?), while also attacking Nine (frenemy) after being called annoying by her. Otherwise they're more friendly when interacting with others, mostly shown in their interactions with Nine. They have a pet cat, and has various hobbies: Painting and drawing, kicking, blowing bubbles, and playing cards/boardgames with other numbers.

A silly number from BFDI who likes to kick people

XFOHV: His first appearance was shown helping X, their best friend, find their value. Likes math/algebra.
BFB: Being the n1 BFDI fan, they hosted a season named 'BFB'. In the first half, Four presents an unpredictable persona; being calm but sadistic and cruel, often zapping/screeching contestants to death in angered. After their enemy, Two, 'stole' their show, Four became more childish, demanding people to stay. He becomes apologetic/nice in the end.
TPOT: Is Chef, still chaotic.

XFOHV: Unlike other numbers, Eight is much more monotone, calm, and reasonable; leaving them to get along with everyone (Ten being their best friend) for being the most respectful member of the group. He likes playing cards, watching Object Show 87, and enjoys the quiet, only wanting a peaceful life. He is supposedly made of pure lead and won 10million dollars from BFTPTMT.

A silly number from BFDI whose pretty normal

XFOHV: Being an introvert, she wants to isolate herself from other numbers, and lives extremely far away from the Equation-Playground to do so. We don't see much of her, but she seems to have violent tendencies; keeping a flamethrower and attacking those who disturb her. She just wants to be left alone. She's lives in a shack, supposedly likes forests, and stole Nine's sunglasses.

A silly number from BFDI who hates everyone

XFOHV: An irritable and sarcastic number, despite being 'bossy', they end up being a more knowledgeable number compared to others; planning ways to trap Fourteen and enjoying books. Despite being one of the smarter ones, he can't pick up a ball. They don't seem to have a sense of humor and is generally law-abiding and logical.
Used to be a stoner.
Likes to read.
Dislikes everyone except for Ten.
Can't have 'fun'

A silly number from BFDI whose surrounded by idiot

XFOHV: She's stereotypically cool. She wears stereotypically cool shades whilst skating around the equation-playground on her stereotypically cool skateboard. Despite trying to seem cool Nine is shown to be the most sensitive of all the numbers as he cries over numerous subjects, such as; Six (frenemy) saying they have no style and Ten's skin getting eaten, she's also afraid of Seven for some reason. She has a cat + a motorcycle, she cyberbullies, and she discovered division

A silly number from BFDI who tries to be cool

XFOHV: Seems to be friends with Nine, but doesn't appear much because they hate math.
TPOT: 'Stole' Fours show by convincing 40/54 contestants to join him. They're shown to be much more calm, being friendly, reasonable, and an outgoing host, but he ends up being a bit of a pushover in return. Two can get irritated when interrupted. Their favorite contestant is Gatey, but he cares about all of them and tries to help solve their problems. Is really powerful, bakes.

A silly number who hosts BFDI/TPOT

XFOHV: Shown for a short bit of time, dislikes the concept of luck and being in an unlucky number (13), perhaps friends with Three and Seven. Considered missing.
TPOT: Supposedly lived inside the moon for 14 years straight, but broke out of it (was either trapped or stayed inside of her own choice). Despite being trapped for such a long time, One greeted the audience happily, seeming sweet and social.
HC: She/They likes space, ends every sentence with an emoticon :>

Silly number who lives in the moon, from BFDI/TPOT

Pretty easygoing - throws a couple funny remarks there and there but generally takes a back-seat in her show. Regardless of that Puffball Speaker Box [PSB] is the most professional host of BFDI, being focused on her work and gets along well with others in and out the show, however PSB holds grudges and can be back-handed. She's still generally wellmeaning.
Died twice.

Sometimes the host of BFDIA

6 teams of 7 and 1 of 1 - will you win the power of Two?

Trying to make this AS accurate to TPOT as possibl

XFOHV: Despite trying to be funny and social, Seven pretty much has no friends (gets along with One, Eight, X, and Ten). They like being in the spotlight which causes them to be pretty stubborn in return; not willing to help others, they are particularly hostile towards Six (arch-enemy) and doesn't get along with Five or Nine. Seven still considers them 'friends' and tries to make them laugh, despite usually being the butt of the joke 90% of the time. Bad cook but is supposedly pretty strong.
