Xaos were 8 to 10 feet tall. So he was twice normal size.

Xaos was immune to any spell that affect its original form, including petrification and polymorph. He was also immune to any critical hit.

Combat
Xaos use his claws to cut up the flesh of his opponents. As special ability the Xaos may use his Corporeal instability attack which could turn the targeted creature into a spongy, amorphous mass. Corporeal instability is not a a disease or a curse and, for this reason, is hard to remove.

History
Xaos was released from the stasis sphere by the evil sorcerer Telkoun Adranther in the Telkoun's Tower. Eventually Telkoun casted the spell Charm Monster on the beast and so he gained control of the creature.
