X

X is the co-host of Battle for BFDI, the 4th season in the BFDI series.

X's first appearance in BFDI is Getting Teardrop to Talk where X 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 badly, with different assets and three fingers all the time.

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 put 4 of his baskets on him, 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.

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 BFB 1 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.
