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 is a number that first appeared in "The Number Playground Chronicle!", where they were a former athlete.
Zero made their first public appearance in "Thanks for 600,000 subscribers!". In that video, five Zeroes are standing next to Six to show off the Jacknjellify sub 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 person to not appear in XFOHV, the second and the first are Nine and Ten.
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 known algebralien to be armless.
One is mentioned by Four in "Thanks for 1,000,000 subscribers!", once Four tells Nine that the subscriber count has reached 1,000,000 subscribers, Four tries to find One (and possibly Zero) but they can't, then 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 for them in the subscriber count.
— 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.
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.
