Six is a recommended character and an algebralian. They made an appearance in "Don't Dig Straight Down" as a recommended character. They also appeared briefly in "Out of the Blue. Six is a sky-blue colored Arabic numeral six: 6. Six did not have a strong defined personality until "Thanks for 900,000 subscribers!". Before then, Six was shown to be somewhat antagonistic to Seven even before Seven kicked them out of the sub count, as they took despicable happiness in laughter when Seven was crying due to not being in the Sub Count in "Thanks for 600,000 subscribers!". They are shown to have a malicious side, such as kicking Seven and agreeing to kick out Eight.

In "Thanks for 900,000 subscribers!", Six appears to be somewhat irritable but also knowledgeable, as they knew that Seven's "ears" were squishy and that was how they were able to kick Seven. However, she is also quite friendly when interacting with Nine. Though this does not extend in helping others in trouble from their fellow kind, as they viewed Pie being attacked by Pi in "Pie Vs Pi: The Pi Day Massacre" as not their (referring to them alongside Two and Eight) problem. Six is seen blowing bubbles at the very beginning of "X Finds Out His Value". 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. They enjoy the sub counts. They made another appearance in "Lo-Fi Beats to Yoyle To", where they are blowing bubbles, much like their role in "X Finds Out His Value". They have fun.

Six was kicked out of the sub count by Seven in "Thanks for 700,000 subscribers!" and spinning around the Earth. Six screams.

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 sought out to help out Nine when requested to in "Thanks for 900,000 subscribers!" by mining stone to create the Stone-To-Boot, for kicking Eight out of the Jacknjellify sub count.

In "Out Of The Blue", they briefly appear while Pencil opens a door in the EXIT and says 'Hey!' as she states that one number is enough to deal with, before she shuts the door. Six is an artist. Six is one of three algebralians to be voiced by a woman. The others are One and Square Root of Two. Six, Nine, Tack and Pie are the only BFDI characters confirmed to have a pet. In both Six and Nine's cases, they own cats. Six's cat is black with white facial features. Six, alongside every other integer, was named "Six Integer" in The Number Playground Chronicle!. Six was credited as the cover designer of Section B: Business in The Number Playground Chronicle! Six is one out of the four algebralians who are blue; the others are One, Four, and Tau.
