Four!

So uh once again to not do this again! sorry!! Four is a poorly-drawn Arabic numeral four. He has a blue wretched, squishy body and limbs that are more lightly-colored. Four is an algebralian, the host of Battle for BFDI & Battle for BFB, temporary host for Battle for Dream Island: The Power of Two, and the host of the non-canon one-episode series, Battle for Permission to Meet 10. Four and his co-host X first appeared as the main protagonists in the 2008 video "X Finds Out His Value". They are also the mascot of Jacknjellify. They appear to be abstract beings representing real-life numbers, letters, or algebraic variables. Four exhibits very surreal mannerisms, including being able to deform or change mutilate characters, revive them, screech to stun them (killing them on some occasions), eliminate them by sucking them into his body (sending them to the EXIT), and shoot energy beams from his hands. Four's first appearance in the entire BFDI series was in "Getting Teardrop to Talk", where they lead a game to win a BFDI. In "B.F.B. = Back From Beginning", Four merged into the Desert. They reformed to their original state in "Chapter Complete." Four makes a cameo on both TV and in the stinger in "You Know Those Buttons Don't Do Anything, Right?". He reappears in "The Great Goikian Bake-Off" as a chef with X. Four temporarily hosts Battle for Dream Island: The Power of Two in the episode "The Power of Four" as a result of Two's depression due to Gaty going missing. Anyways! you can be X or anyone!
