Chaos

ケイオス

Chaos is a playable character in the Xenosaga series. Little is known about Chaos or his past. His personality is kind and gentle, displaying a philosophical wisdom and maturity that betray his true age. He rarely seems upset or stressed, taking almost everything in stride. Chaos's easygoing and contemplative nature is such that Jr. even accuses him of being "so slow." Most people, even complete strangers, find his presence calming and soothing, often opening up to him completely with their problems, as was the case with Allen. However, despite his cheerfulness and seemingly carefree attitude, Chaos is commonly described as having a near-perpetual melancholy expression stemming from some unknown anxiety and unfulfilled state. Although he often says that he doesn't like to fight, he nevertheless does so to protect others and to help his friends.
Chaos's name is always deliberately written in lowercase, although the reasoning for this is unknown. This stands in direct contrast to KOS-MOS's name, which is always written in uppercase (because it is an acronym). Another contrast between the two characters is the derived meaning of their names. Chaos literally means anarchy and confusion, while kosmos means "order" in Greek.
In official artwork, he is sometimes portrayed with six white angel wings.
