Melleck Xaos

Melleck Xaos is the name of a fictional character, the principal villain in the web comic The Wotch. The "X" in "Xaos" is actually the Greek letter chi (χ), so the name is pronounced as "chaos".

This may be a reference to the Yazidi peacock-god Malak Ta'us, or maybe to Alan Moore's comic Top 10, where there is a character named King Peacock who is a Yazidist.
