An exceptionally old and wizened member of the Joketsuzoku tribe, and Shampoo’s great-grandmother. If Cologne has lost any steps due to old age, she conceals it well, for she is intelligent, extremely canny, and an incredibly adept martial artist. Well, it’s true she has lost the beauty (and height) of her youth, but she does not like to be reminded of these facts.
While powerful enough to easily defeat the likes of Ranma, Cologne mostly prefers to play the role of advisor, sage, and annoying old meddler in other people’s affairs. However, she seems to have the best interests of her great-granddaughter and others she takes a liking to at heart, and will often offer advice, aid, or artifacts from her considerable collection of powerful magical items without requiring any form of payment.
Cologne knows a great deal of ancient lore, mythological, magical, and martial. While wise, however, she is not infallible, and has been known to underestimate foes.
