Algebralians

Algebralians (a demonym derived from the word "algebra") are a fictional genus of colorful, sentient beings based upon mathematical symbols that are from the Equation Playground. They are notable for their appearances in "X Finds Out His Value" (XFOHV), "The Number Playground Chronicle!", and Battle for BFB.

Note that the only canonical appearances of Algebralians are from Battle for Dream Island. Their appearances in the pre-BFDI comics and XFOHV are considered not canon, meaning they are not part of the central universe and timeline of events.

Trivia

• The term "Algebralian" (also spelled "Algebralien", a portmanteau of "algebra" and "alien") was invented by fans of Battle for BFB, and was later adopted for use by Cary Huang, solidifying the nickname as an official name.
• Algebralians might have very fragile skin. In BFB 17, Two says that glue can damage an Algebralian's pelt, even though they never say how.
