X (Battle for BFDI)

"NO MORE SCREECHY PLEASE!"

- X to Four in BFB

X is the co-host of Battle for BFDI, the fourth season in the BFDI series.

X's first appearance in BFDI is in Getting Teardrop to Talk where he and Four lead a game to win "a BFDI" (in which it means the winners will get another battle for Dream Island). X appeared alongside Four, another abstract being representing a real-life number or variable. He had died in Four Goes Too Far along with Four. X can be seen inside of fries in Questions Answered, and he comes out of fries to host again in This Episode Is About Basketball.

Appearance
Similar to Four, he is purposefully drawn simplistically, with different assets and four fingers on each hand.

Role
X plays a role as Four's assistant. and is passive by their latest appearance in Lick Your Way to Freedom.

He sets up the challenges as seen in Getting Teardrop to Talk, where the contestants must reach X to bring his baskets back, while Four says that teams are safe and which team is set for elimination.

X is the person who hands out prizes to the safe competitors at Cake at Stake. He did not do this in Why Would You Do This on a Swingset because he was sent to the "burn center".
