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.
Zero made their first public appearance in "Thanks for 600,000 subscribers!". In that video, five Zeroes are standing next to Six to show the Jacknjellify subscriber count. This marks the first appearance of Zero's clones.
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.
They appear again in "Thanks for 900,000 subscribers!", fulfilling mostly the same role as they did in the three previous videos.
They appear yet again in “Thanks for 1,000,000 subscribers!”, fulfilling mostly the same role as they did in their previous appearances.
- Their limb and body colors are very similar, but are not the exact same shade.
- Zero's color is taken from an empty cell in Minesweeper.
- Zero is the third algebralian to not appear in XFOHV, the second and the first are Nine and Ten.
One is an algebralian and recommended character from the bfdi universe.
In X Finds Out His Value, X finds out that their value is seven, which is considered to be a lucky number. 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, likely due to One and Three forming into a Thirteen, which is considered 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 armless.
One is mentioned by Four in "Thanks for 1,000,000 subscribers!", but never makes an appearance. Once Four tells Nine that the subscriber count has reached 1,000,000 subscribers, Four tries to find One (and possibly another Zero) but they can't, and everyone decides that finding Ten is the best alternative. Seven also mentions that One is their BFF and that they could take Ten's place in the subscriber count.
- One is so far the only major algebralian character to have no arms.
— Three, "X Finds Out His Value"
Three is an algebralian from "X Finds Out His Value". At the beginning of the video, they are seen playing catch with Five. Later on, they become jealous of Four and X when they find X's value is seven, a lucky number, while with One, they form into a thirteen, an unlucky number. Three grunts at the sight.
Three appeared in the traditional art style for the first time as 2 recommended characters (recommended twice) in BFB 27, and once again in BFB 28, and thus was the last XFOHV character to appear in the BFDI universe.
Coincidentally, they've been recommended 3 times.
