X

X, full name X Variable, is a Latin 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. X seems to be much more friendly than Four, and is usually seen to be quite happy and friendly towards the contestants and other people Im general. 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. 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. After returning in TPOT, X is the hotel’s chef with Four, being more similar to his early-BFB self. Like Four, he is strange and erratic in behavior, and can sometimes be cruel or violent to the contestants. In general, X is still the more peaceful and good-natured of the two; he simply shares Four's unusual and alien morality.
