X

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.

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

Coverage
X's first appearance was in a 2008 animation X Finds Out His Value along with Four, nine years before first appearing in the BFDI series in Season 4, with Four possibly making up as a host and running gag because of the season they first come back in. This also shows that X doesn't refer to the English letter, but the algebraic variable or the math symbol of multiplication.

X played a major role in the challenge in Getting Teardrop to Talk. The contestants had to return his baskets back to X, who was standing on a tall platform, in order to avoid elimination. At the end of the episode, X puts on 4 of his baskets, causing him to spin fast.

In Lick Your Way to Freedom, X collaborates in the Cake at Stake as the character who throws the cakes, with Four being the one who says who is safe and who goes home/gets eliminated. Later in the episode, he warns Beep that Four won't like the fact that Roboty was missing. Once Beep loses, X tells them that one of them will be eliminated.

In Why Would You Do This on a Swingset, X reminds Four that it's called Cake at Stake, and not Brake at Flake, prompting Four to insult X. Four later causes X to cry when they say that nobody noticed he was gone, despite Cloudy noticing.

In Today's Very Special Episode, Four once again causes X to cry during Cake at Stake when X got the number of votes wrong. X also translates Four's muffled speech. X assists Four in placing the team tags on the rating scale during the challenge and offers his opinion on iance's and Death P.A.C.T.'s make-overs. The Loser's make-over was a papier-mâché mold encasing X, which may have contributed to their low placing at 7th.

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".
