The niku-man men (Niku, An, Karee, and Piza)

In the Tsinghai region of China, four little men come to the Yakusaikan store seeking a 4000 year old secret "dragon's hair" of mysterious power. They coerce the shopkeeper to draw them a picture of the person who has it now, who has a conspicuous pigtail. Finally they find Ranma, who uses it to tie off the end of his pigtail and never removes it because it's his "seal". But when they do remove it...

Nodoka Saotome

Later on, Ranma saves her when she falls off a cliff. She then agrees that Genma has kept his promise and that Ranma is a manly man. However, they fall into the water and Nodoka finds out about Ranma's curse, but decides they don't have to commit seppuku after all.

Herb

Not sure whether or not that's his cursed form.

Leader of the Musk Dynasty with the ability to fly. Said to have dragon genes, direct from his ancestors. When he threw a monkey in Nyanniichuan, he was so captivated by his first sight of breasts, the monkey girl pushed him into the spring too. Then, captivated by his/her new body, the monkey girl splashed her with Chiisui-ton (stopping water bucket) water. So Herb came to Japan in search of the long-lost opposite to the Chiisui-ton, the Kaisui-fuu (opening water pot). Wears gold armor, which reflects blinding light into opponent's eyes. Also said to weigh Herb down and keep him from flying away!

Mint

A wolf-boy with superhuman speed, who has never seen a woman before. When Herb paid a visit to Cologne, being fascinated by just seeing women, Mint beat up Moose and "kidnapped" Shampoo. Throws knives incredibly fast.

Lime

A tiger-boy with superhuman strength, who has never seen a woman before either. While Mint "kidnapped" Shampoo, Lime beat up Ryouga and "kidnapped" Akane. Later, in the Nekohanten, when Herb told Mint and Lime that they were leaving, Lime threw Akane away (who was caught by Ranma, who became really really pissed...)

Ryu Kumon

A martial artist who was given a scroll for the Saotome school technique Yamasen-ken developed by Genma long ago. After saving Ranma's mother from a rampaging bear, he drops the scroll, which Nodoka picks up and returns to him, thinking that he's Ranma. Nodoka becomes happy to see him (since she thought he was Ranma), so he plays along, thinking he might be able to get his hands on the scroll for the complementing technique, the Umisen-ken. With the other scroll, he intended to restore his dojou, which had been falling apart. While practicing on the house, he accidently brought it down, which killed his father (and where do you suppose the blame goes?)

Kinnosuke

When Nabiki is on a typical 'date' (ie: sponging off the poor guy) one day, she feels that someone is watching her. She then receives a date-challenge, so she forces Ranma (as a girl) to go in her place. A nice looking guy (Kinnosuke) shows up saying it was a joke, so Nabiki shoves off Ranma and gets treated to an expensive meal. But Nabiki doesn't bring her purse on a date, and Kinnosuke uses a silly butler hand-puppet to get out of paying- Ranma and Akane get the bill. They soon find out that Kinnosuke is from the Kash-oo School, which sponge off others. Nabiki resolves to drain every penny Kinnosuke has, while Kinnosuke wants to force Nabiki to spend her money. Nabiki seems to be in love with Kinnosuke, but they break up after their second date.

Akari Unryuu

Late in the series, Ryouga casually beats a huge pig while fighting Ranma. A girl runs up to him, and gives him a letter and runs off. Ryouga and Ranma are surprised that it is a love letter from a girl named Akari Unryuu. When they meet her again, Akari explains how her late grandfather told her that she could only marry someone who was strong enough to beat their champion sumo pig. Akari starts going on about how she think's Ryouga's her perfect man - strong, robust, intelligent, gentle, etc. like a pig. Ryouga thinks that she's making fun of him being part-pig and runs off. She becomes overjoyed when she finds out about Ryouga's curse. Wears a red ribbon in her hair.

Rouge

When the Tendous and Saotomes are watching a TV broadcast where they see Pansuto-monster being attacked by a bright light earlier in China, he literally drops in, all beaten up. Meanwhile, when Akane is coming back from tennis, she sees a bright light and a splash is heard from a nearby fountain, where she finds a steaming fountain and a naked girl getting out. Later, the girl introduces herself as Rouge, a poor beautiful girl who was peeped on and robbed while taking a bath by a vulgar, evil (etc.) guy- who they later find out is Pansuto Tarou. When he sees Rouge, he becomes a bit pissed off and tries to beat her up- only to be beaten up by the others. No one believes him when he says that he's the victim and when he protests he stole nothing from Rouge, so he turns into a monster, and busts up the house a bit before leaving. Later, they find out that Rouge was the bright light that they saw earlier, and that Rouge had fallen into (or was doused with water from) the Jhusenkyo spring where the strongest Indian warrior Goddess Asura had drowned 4000 years ago. Rouge's cursed form has 3 heads, and 6 arms, and emits a serious amount of energy.

Asuka Saginomiya

Ten years ago, when Kodachi and Asuka were in kindergarden, they had fought over who could get the coolest boy (and beat up each other's boy) which Kodachi had won, so Asuka challenged Kodachi to a double-date duel 10 years from then over who has the coolest boyfriend. Almost like the a twin sister of Kodachi, as she uses many low and underhanded tricks. Also known as Asuka the White Lily.

Konatsu Kenzan

A martial arts genius, whose like only appears once in a century. Was brought up as a female ninja, and regards himself as a girl. When Happosai took Ranma and Genma training, they visited the Konoichi (female ninja) tea-shop. At a nearby river, Konatsu was working, doing chores in a standard, but worn ninja outfit. When he got ready to go back to the tea-shop, he saw it reduced to rubbled by a Happoudaikarin. His (her) step-mother and step-sisters send her off to get revenge on Happousai, Ranma and Genma. Rebels against his step-mother and step-sisters when they kidnap Ukyou (and later, Akane). Cooperates with Ranma and they rescue Ukyou and Akane. Shocked everyone before they found out he was a boy when he wrote on a scroll `Konatsu loves Ukyou, even though it's "forbidden"'.

Konatsu is the typical Cinderella, doing all the hard work. Taken in by Ukyou and works at Utchan's as a waitress.

Plum

The Jhusenkyou guide's daughter, who is sent to Japan carrying a map of Jhusenkyou. She is attacked by the bird-men of Phoenix Mountain, but is rescued by Ranma and Ryouga.
