the reason 15 is popular is probably because, the higher the number, the more popular. Thats why even 10 liked 15, so considering that i think 1 wouldn't be very popular.

wait actually look at this:

I am pretty sure the algebraliens inherit other's traits only if they combined, like six and nine. And maybe you are right, but, their photos (like in 1:33) kind of depict their personalities. So i am sure that one's personality is either extremely annoyed by everything (unlike five, who isn't always annoyed) or has anger issues.

If so then imagine on the Thanks for 2 000 000 subs vid Twenty shows up and then says :

well that explains why 14 is insane

I hope we get to see One and Three in the future! And I actually believe One is popular thanks to you!

With this logic all of the 20's are british

nice to see people talking about one

i love this theory! this could actually be real. i hope to see One in the future!

Yeah , 14 acts like pre split 4 where he kills anyone just because

This actually seems like it could be real, good job!

(Spoiler alert for now)

“And fourteen can causally get away with eating people’s skin”

this theory is actually super good keep it up

Maybe One's personality is that they show extreme emotions/mood swings? As we have seen that 14 personality is like 4's but chranked upto its extreem and the same with 15 as they're alot more grumpy and violent than 5 maybe but idk (and it maybe true that their personalities are a combination of the numbers they are made of)

I like to think that being a first contributer in anyway of a big channel/from a big audience (in this case, first from millions of people) can make them VERY special. In example, knda like how JSB Blue Jay became popular because of being the first voter of bfdi!

“In thanks for 1000000 subscribers”, Ten (10) is described as athletic, and 0 is a “former athlete”, as stated in Number Playground Chronicles. Coincidence? I think not.
