Not much REAL information is known on Xelloss. He doesn't exactly talk much about himself; in fact, his response to most if not all personal questions is "sore wa, himitsu desu" (Literally, "That is a secret."). However, there is some information which is known:

Xelloss is the general-priest of Greater Beast Zelas-Metallium, one of the Mazoku lords underneath Ruby-Eye Shabranigdu. Most people tend not to trust the main subordinate of a major demon, and rightfully so -- on more than one occasion, Xelloss has (apparently) doublecrossed those who may have considered him a friend. However, he doesn't really doublecross anyone; anyone who follows the trail of clues which Xelloss leaves behind actually sets themselves up for trouble. You see, Xelloss prefers lying in the shadows, for to simply tell you the answer isn't very fun at all, now, is it? Xelloss would rather give someone a gentle nudge here and there towards the direction which he wants them to go, and let them figure it out. Xelloss talks very little, except to make trouble. He might tell a story, but the parts he leaves out of the story are probably a lot more important than the ones he tells. He even has a habit of disappearing for seemingly no reason at all, coming and going as he pleases.

Xelloss has reputation of being a bit of trickster - he even calls himself the "Trickster Priest" from time to time. He roamsthe countryside with his bag of pranks, bringing trouble and good fortune wherever he went. He always seems to prefer a good laugh to the 'proper' thing to do, though.

However, Xelloss also has a nasty streak in him. He's a bit of a glutton for punishment, seeking to hurt, and to be hurt. He has no respect for boundaries, or when to shut up, or anything like that; he has little if any fear of ANYTHING. Partially due to Zelas-Metallium, he has almost no weaknesses, so his fearlessness is somewhat justified. Damage means little - he can regenerate fairly quickly, and physical damage is nigh irrelevant. Xelloss is even resistant to most non-physical attacks such as magic, even many attacks coming from other Mazoku. The nature of Xelloss' resistance is not quite known.

Above all else, Xelloss is loyal to his master. Zelas-Metallium has a secret agenda, and Xelloss does a very good job of sticking to it, as well as keeping it secret. No one is quite sure of what 'the plan' is, and Xelloss sure isn't revealing it. Supposedly, Zelas-Metallium was in cohorts with the Hellmaster Fibrizo before his demise, but, again, the details of the alliance are shaky at best.
