Koron

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.
