X

X from Battle for Dream Island (BFDI) is generally a friendly, supportive, and nervous co-host, often overshadowed by Four, but can show darker, meaner, or even insane moments, revealing a more complex personality that sometimes acts out due to mistreatment or becomes sarcastic and condescending, especially as the series progresses. He's a loyal Algebralien, but also capable of sudden cruelty, making him a mix of gentle and volatile.
