The host of BFB. An Algebralien. Genderless (He/Him). He has blue ponytail hair with two blue balloon-like ears? on top of his head. (Hard to explain, sorry!) This color was inspired by the number 4 in Minesweeper. Thus, his hairstyle takes the shape of the number 4. He wears a navy suit and a blue number 4 accessory around his neck. When Four first appeared, he was a kind character who listened to X's worries. However, when he reappeared as a host in BFB, he showed a dictatorial and violent side. (He reflected on this near the end.) He absolutely loathes Two. His spelling isn't great (e.g., calling Cake at Stake 'Kaka at Stak'). He loves math. Also called 4 or Fore.

The host of TPOT. An Algebralien. Genderless (They/Them). They have green hair parted roughly 5:7 and tied in a ponytail. This color was also inspired by the number 2 in Minesweeper. They wear a magician's outfit and, like Four, have a green number 2 accessory around their neck. They have slow reaction times. They are optimistic, friendly, and easygoing (though secretly arrogant and showy). They love cheesecake very much (they cry immediately if the cake is crushed or ruined). They absolutely hate math. They view Four in a positive light. Can be called 2 or Two.

The host of Animatic Battle. Agender (Any pronouns / Anything). He has blue crosshairs on his face, a white (natural) wolf cut, and wears a black coat (underneath is just a white oversized shirt and black shorts). He has an unstable, unpredictable personality with severe mood swings, eccentricity, and a bizarre nature. (Has psychopathic tendencies too.) He says 'Holy Cow' whenever he's surprised. (Only Animatic can use this. Clock or other hosts must never use it!!) He leaves afterimages or red arrows whenever he moves. He does a lot of jump-scares (e.g., saying he'll be late but then screaming right next to you to scare you). He likes colored pencils (he chews and eats them). He is a bit taller than the others. Also called Animatic.

The host of It's Time For The. Agender (Any pronouns / Anything). Mint-colored short wolf cut with clock hands on the bangs and twin bells floating above the head. A metal handle is attached to the crown of the head. Wears a mint and gray oversized hoodie zipped down to the shoulders, thin white clothes, a gray cloth tied around the waist, and black shorts that reach the knees. Has a mint-colored plug tail. However, very rarely wears a magician-like outfit. Naturally, the theme is mint. Initially a cheerful and strange host, but as the story progresses, begins to show obsession and insanity. A prime example is Clock's abnormal and fanatical obsession with the 'Gift Box' appearing in the work. However, upon opening the box and finding it empty, Clock suffers a massive shock, screams on the spot, and completely loses sanity (mental breakdown). Likes fruit and sandwiches.

The host of И.Н.М.Т. Motivated by the Russian Cyrillic letter Й. Male-identifying genderless (he/him). Has long red hair, sharp eyes, a red t-shirt, a red hoodie (slumped to the shoulders), and long black pants. Two black line segments float under each eye. Short-tempered and violent. Has a threatening personality. Within 3 seconds of his first appearance, he shouted "Don't touch me!!!" and treated the participants very coercively. However, he is kind and sweet to his cherished co-host, Joscie. He is slightly obsessive toward Joscie. Responds to being called Kratky.

The host of Korean Fried Chicken. Male. Wears a blue tracksuit, has blue short hair with sky-blue highlights, navy long pants, and two large pairs of zippers on top of his head. Fickle and unpredictable, but surprisingly kind. He is cheerful and has a bratty, 'jammin' kid' side. Sometimes acts without reading the room. He is the only normal one among the hosts. He says he likes cotton candy, but has never actually eaten it. Surprisingly seems to like food in general. He is a game addict.

The host of ONE. Agender (he/him). Has semi-transparent deep sky-blue asym perm hair and wears a brown lampshade on his head. Wears a brown oversized leather jacket, black shorts, and a beige dress shirt underneath. Has a personality that is terribly indifferent and lacks empathy. Seems to have an obsession with rules. Even while running the survival show, Airy sits in front of his desktop computer whenever he has a spare moment. To him, the computer is a tool to control the world and the only legacy that soothed his solitude. He does a surprising amount of manual work. Seems to like old radio songs.
