X

X is a variable and the co-host of the fourth season of the Battle for Dream Island series, BFB. X is a drawing of the letter X with a yellow body and lighter yellow limbs. Similar to Four, they are purposefully drawn simplistically, with different assets and four fingers. X plays a role as Four's assistant. They set up some of the challenges and host Cake at Stake, sometimes handing out prizes to the safe competitors. X seems to be much more friendly than Four, and is usually seen to be quite happy and friendly towards the contestants. However, X also seems to be quite soft, as they cry after Four stated that nobody noticed their disappearance (despite Cloudy asking about X), and became frightened after Four screeched at them and when Snowball threatened them in "This Episode Is About Basketball". He has a squeaky voice. They can also be considered a bit ignorant, such as thanking the ground for "catching" Beep after they fell from their plane, or even asking to get screeched by Four. They can also show to get very nervous under pressure. As they host in "This Episode Is About Basketball", they're very hesitant while talking and tends to mess up things, such as reading the votes backwards when Free Food was up for elimination. X is overall quite docile by nature and remains loyal to Four, even after the times Four has mistreated them. In "Fashion For Your Face!", they have become more confident in hosting. However, in "A Taste of Space", they show a more irritable, somewhat bratty side to their character as they begin subtracting points from the teams for petty and minor reasons. Notably, in "B.F.B. = Back From Beginning", it is shown that X can be pushed to their limits. When they mistakenly believed Teardrop wanted to quit BFB and didn't care, they shot some sort of zappies out of their eyes which instantly killed Teardrop. It can be assumed that Four's abilities are not unique.
