Four

Four  is the main host and arguably the main antagonist of Battle for BFDI. Four and his co-host X first appeared in the video "X Finds Out His Value". Four exhibits very surreal mannerisms, including being able to deform characters strongly, reviving them, screeching in order to stun characters, eliminated contestants by sucking them into his body (sending them to Eternal Algebra Class), and has the ability to shoot laser beams (called "zappies" by Nickel) from his hands. Four's first appearance in BFB was "Getting Teardrop to Talk", where he leads a game to win "a BFDI" (in which the winners will possibly get another Battle for Dream Island). Four appears alongside X, another abstract being representing a real-life number, letter, or algebraic variable
