Xanthos is a skinny, silver male Water Dragon with gold eyes and aqua colored wing membranes. He has several scars and bruises covering his entire body.
Xanthos is the "older" twin brother of Balios, and the older adoptive brother of Pedasos. He also has a younger sister, though she is deceased. Xanthos has always been very kind to others. He sleeps a lot, mostly to try to get away from Balios. He is a good hunter, but an extremely poor fighter. He dislikes violence, especially after his parents' murder when he was still a hatchling.
He was seen talking to Asurai in the Dragon RP, and shortly after he was beaten up by Balios for locking him inside the den.
