This article is about the relationships and interactions between X and the other characters.
X acts much nicer and docile towards the contestants than Four, most of the time at least.
In "A Taste of Space", when X has cooled down, Blocky shines a mirror back to the sun, making the sun hotter, and making X burst into flames again. This results in his team losing 1 point. Later in the challenge Blocky complains to X that their team got fewer points than the Have Cots. This results in Blocky's team losing 3 points, since he was "being mean". When Blocky freezes the sun by insulting it, X is angry since it's now way to cold, and subtracts 7,000 points from his team. When Blocky puts a block around the Earth to protect X from the sun, X does not see it as an improvement, and takes away 8,422 points from his team.
In "How Loe Can You Grow?", Bubble asks X if he's actually trying to grow aloe vera. X says he is, so Bubble informs him that aloe vera can't grow in the biome they are in, due to too little sun. Later, X asks Bubble how she knows so much about aloe vera. Bubble explains that she uses it to keep her skin moist and demonstrates by rubbing some on herself. X says he's happy to hear that it works for her. When Lollipop demands an answer from X, Bubble tells X he doesn't have to answer unless he's comfortable. X says he can, but just needed to figure out how to word it.
In "Enter The Exit", X talks to Cloudy because he is sad that Balloony is dead. X tells him that he will be safe before the elimination starts to make him feel better.
In "Enter The Exit", Four is not available to take David to EXIT, so he tells David to go "be eliminated" until Four comes back. David yells "No!" and runs away from X. X manages to catch David and shoves him inside his head.
