Numbers in this article must be official numbers that have appeared in videos such as X Finds Out His Value, BFDI, or in shorts. Recommended characters and promotional characters that are numbers are excluded.
They appear again in "Thanks for 700,000 subscribers! (Leafy Plush & BFB 22 on July 24)", fulfilling mostly the same role as they did in the previous video.
They appear again in "Thanks for 800,000 subscribers!", fulfilling mostly the same role as they did in the two previous videos. They appear to be upset when Seven gets kicked.
After X finds out his value, which is seven, One is seen watching Four and X with an angry expression on their face. Three, who is next to One, is also seen angry at Four and X. This could likely be due to seven being a lucky number, as Four mentions, and One and Three forming Thirteen, which is an unlucky number.
In the original storyboard of "X Finds Out His Value", One was supposed to say "Hmph!" instead of Three.
One has appeared in the traditional art style for the first time as a recommended character in BFB 25, which revealed One is the only Algebralien to be armless.
— Three, "X Finds Out His Value"
Three is a number from "X Finds Out His Value". At the beginning of the video, they are seen playing catch with Five. Later on, they are jealous at Four and X when they find X's value is lucky, while with One, they make thirteen, an unlucky number..
Five is seen in "The Four is Lava", where he was engulfed by lava.
|“||Ooh hoo-hoo! Revenge time!~||”|
— Six, "Thanks for 800,000 subscribers!"
Six is seen blowing bubbles at the very beginning of XFOHV.
They reappear as a recommended character in "Don't Dig Straight Down".
Six appears again in "Thanks for 600,000 subscribers!", where they are maliciously standing next to five Zeroes, forming a representation of the jacknjellify subscriber count, angering Seven.
Six had to be brought down from the orbit in "Thanks for 800,000 subscribers!" by Four and the other numbers. After being told Eight needed to replace Seven, they happily kicked Seven out of the sub count stating "Revenge time!".
Six appears to be rather vengeful, as seen in "Thanks for 800,000 subscribers!", where they kicked Seven out of the sub count due to Seven kicking Six out of the sub count in "Thanks for 700,000 subscribers!". They also enjoy blowing bubbles.
|“||Ahh!! I'm sorry!! Help me!!||”|
— Seven, "Thanks for 800,000 subscribers!"
Seven is seen sitting on a bench relaxing. Seven reappears at the end of the video dancing with X and Four after X found out his value was 7. They appear in Battle for BFDI as a cameo in the alternate Cake at Stake Intro in "Today's Very Special Episode". Four referred to them using singular they pronouns in "Thanks for 600,000 subscribers!".
They appear once again as a recommended character in "Return of the Rocket Ship". They appear three times in the episode. First, they were watching the Cake at Stake ceremony with the other recommended characters. They are then seen watching Fanny fly over the second group of recommended characters, and finally, they are seen underground with the third group as A Better Name Than That is digging with their rocket ship.
They then reappear in "Don't Dig Straight Down" as a recommended character.
They reappear once again in "The Four is Lava" as a recommended character near the end of the episode where Clock seems to be talking to himself. This is their fourth appearance in a row.
Seven makes their first official reappearance in "Thanks for 600,000 subscribers!", where they are crying because they want to be on the sub count, but 6 is instead.
In "Thanks for 800,000 subscribers!", Seven was seen not wanting to leave the sub count.
Seven only cares about being in the spotlight, according to Eight. Seven is a whiny person, due to them crying over not being in the sub count (and therefore not in the spotlight) in "Thanks for 600,000 subscribers!". As well as selfish, stubborn and uncaring to an extent, shown by them being unwilling to help the other numbers catch Six and to leave the sub count so Eight can take their place in "Thanks for 800,000 subscribers!".
|“||If the viewer wants to subscribe, g-great! But if they don't want to subscribe, that's cool too.||”|
— Eight, "Thanks for 700,000 subscribers!"
Eight is one of the numbers in the Equation Playground, saying "Huh?" when Four touched them and put them on the seesaw.
Eight appeared again in "Thanks for 700,000 subscribers!", when Four asked Eight about the fact that Eight may be the next number on the sub count. Eight responds with the fact that they don't really care about it and it's up to the viewers to subscribe. Four then praises Eight, only for Eight to remind Four that he called Eight "too heavy" in "X Finds Out His Value".
Eight appears to be somewhat apathetic and inspiring, but also seems to remember things from long ago that may upset others. Eight does not seem to have a strong opinion on many things and sometimes comes off as irritable.
|“||Whazzup guys? As you can tell by my rapper sunnies, I'm the awesome one around here!||”|
— Nine, "Thanks for 800,000 subscribers!"
Nine's personality appears to be based upon the exaggeration of the skater subculture in the late 1990's and early 2000's, using slang such as "tubular", having sunglasses, and owning a skateboard, which was very popular around that time period. As a result of this, Nine acts like they're very cool.
- Nine is the only minor number to not be originally created by Cary and Michael Huang, as they originated as a recommended character by MiitopianOlive.
- Despite Nine's appearance having a light gray shade color, when they were recommended by MiitopianOlive, they were meant to be white.
- Nine was given a skateboard and sunglasses in their appearance in "Thanks for 800,000 subscribers!". It is unknown if Nine has these items all the time.
- The shine design in Nine’s sunglasses seems to be a flipped version of the background in Gelatin’s voting icon, and the Final Fourteen picture.
- Nine's skateboard has a color scheme similar to the shine design on their sunglasses.
