Algebralian

A fan-made term used to describe numeric characters from the long-running YouTube show, Battle For Dream Island, or BFDI, originating from an educational video titled X Finds Out His Value. It is used most commonly to describe original characters of the species, but is also referred to the canon characters, X, Four, and Two. The term currently has never been accepted as canon into the show, but the official Twitter account, Jacknjellify, had used the term when describing artwork.

Four is a funky little Algebralian.

algebralien

An alien that’s an algebraic symbol such as four, x, and 2 the most popular of their species, the algebraliens usually are found in the number playground and which is where they were first introduced specifically four and x they were finding out the value of x and spoiler alert…. He equaled to 7! The algebraliens don’t have genders but people presume four, x, and 2 being male and fun fact all of the algebraliens have all their limbs except one. How weird is that?

Person 1: hey who’s your guy’s favorite algebralien?

Person 2: Personally I like nine since he’s cool

Person 3: well I like x because he’s adorable

Person 1: I honestly like 7 although he’s the most hated I think he’s just super underrated
