Four is an algebralian, the main host of BFB, and the host of the non-canon one-episode series, Battle for Permission to Meet 10. Four and their co-host X first appeared in the 2008 video "X Finds Out His Value". They appear to be abstract beings representing real-life numbers, letters, or algebraic variables.
