Chapter Complete (flanderized)
Four is an integer and the main host as well as one of the three main antagonists (alongside Announcer and Purple Face) of BFB, and 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.
