Колон

Cologne is the great-grandmother of Shampoo. She accompanies Shampoo on her return to Japan, and opens the Cat Café in Furinkan. She is a contemporary of Happosai, and well over one hundred years old. She calls Ranma "bride-groom" and "son-in-law" due to her attempts to have him marry Shampoo, and just to watch him become enraged. She is a grand master of martial arts, and occasionally teaches Ranma and his rivals new techniques. She gets around by pogoing on a gnarled wooden staff that she sometimes uses as a weapon.

She is the grand master of the Chinese Amazon martial arts, allowing her to manipulate water and ice, create whirlwinds using an opponent's aura against them, shatter inanimate objects with a simple touch, and touch pressure points to make a person feel like they are burning with even the slightest amount of heat. Cologne is knowledgeable in several other disciplines such as arcane lore, cooking, Chinese mythology, and magic artifacts. (Source: Wikipedia)
