Kuno is an Idiot. And that's almost Insulting to idiots when I say that. He lives in his own little fantasy world where he is the Greatest Swordsman to ever live, and if he is ever defeated, it must be due to his opponent using foul Black magic. He tends to Glomp Ranma-chan whenever he gets the chance, spouting phrases like "Come to my arms, my fair Pig-tailed Goddess!" etc etc etc. Whenever he gets the chance to buy cheesecake photos of Akane or Ranma from Nabiki, He pays whatever price Nabiki asks for them, out of pocket. He comes from a rich family so money is not a problem for him. He hates his father too, who is a nut with a penchant for Buzz cuts. In fact, the whole Kuno Line is a walking talking Insane asylum. I think Tatewaki Kunos mother is the only sane person to ever be a part of it. She's dead though.
Tatewaki also has a habiot of spouting flowery poetry at all times when he speaks. Excepting situations where he is Extremely surprised or is information Nabiki of how much he loathes her. "I hate you." "I know, Kuno-chan."
Tatewaki doesn't realize that Ranma girl form, and Ranma as a guy are the same person. He thinks that Ranma is an Evil Sorceror, who has Ensorcelled the fair pigtailed maiden (Ranma Girlform) and is keeping her from him with black magic. He also believes that Ranma is keeping Akane from him in the same manner, even though Akane was pummeling him long before Ranma ever showed up.
He does have some small amount of skill though. He can strike with a staccato thrusting attack that can damage just from the air-pressure. It's a small additional in his favor, but it doesn't add up to much.
Elder Khu Lon is a Complex Character, She's over 350 years old. She's also the Matriarch of the Joketsuzoku Amazons, (The Head leader of the village.) Being in that position in an amazon society should give you some small indication of her martial ability. She is actually a Walking repository of Martial Arts Knowledge and knows many Special Techniques, Ki attacks, and Esoteric Pressure points, such as a "Sleeper point" that knocks an opponent unconscious, the "Cat's tongue full body shiatsu" technique, a pressure point that makes ones body extremely sensitive to heat, as well as many others. While many people can Claim, "Well NOW I've seen Everything" Cologne is probably the only one in the world who can make that claim truthfully.
Cologne is Adamant about the Amazon Laws being upheld and is doing everything in her power to ensure that Ranma comes back to Joketsuzoku with them. Or so everyone thinks, Given the amount of chances she's had to do so, One wonders if she really means to keep helping Xian pu capture her "husband", or if she merely enjoys teaching Ranma in the Martial Arts.
She does have a Habit of calling Ranma "Son-in-Law". She is also short in stature, about the size of a small child. she carries a Staff twice her hieght and her usual means of transportation is hopping on her staff, which puts her almost at eye level with most adults.
One should not judge Elder Khu Lon by her stature, she is a fierce opponent in battle, having defeated Ranma Many times over the course of their interactions. In the Beginning of the series right after Happosai was freed, she was the only one able to go Toe to toe with the old Lecher, and it was a fierce battle even though she was defeated.
