A young boy who practices the martial arts. He can be very rude and annoying at times. He doesn't like to have relationships much. He transforms into a young girl when hit by cold water and back with hot water. In his girl form he is admired by the likes of Kuno, to his disgust. His signature move is "Roasting Chestnuts on Open Fire" (weird name...) It involves retrieving chestnuts from a bonfire w/o getting burnt. He constantly fight with his father and his fiance, Akane.

She is very mad at the fact that she was engaged to be married without her consent. She also studies the martial arts. She can act very much like a tomboy at times, but her looks say otherwise. In the Tendo household, she is infamous for her horrid cooking skills. To Ranma's displeasure, he is her favorite taster for her creations.

He is Ranma's lazy father. He has taught Ranma everything he knew in the martial arts. He is a bit of a loafer and a glutton, at the same time, though. He transforms into a panda when soaked in cold water. Whenever he's in panda form, since pandas can't talk, he holds up wooden signs saying what he wants.

He is one of Ranma's rivals. He has a really bad sense of direction (when I said bad, I meant really, really bad). He is cursed as a small black pig. He blames Ranma for the curse, which is why he wants to kill him so badly. Akane adopts his pig form as "P-chan" not knowing his real identity. His signature move is the "Breaking Point" which shatters anything he touches with a point (no effect on humans). He later changes it to the "Lion's Roar Blast" which depends on his amount of depression.

He is an upper-class man in high school. He always carries around a wooden sword like a swordsman. Unfortunately, he is pathetic compared to Ranma. He is absolutely obsessed with Akane and the "Pig-tailed Girl" (Ranma's girl half).

A vicious chinese amazon woman who was defeated by Ranma's girl half. According to their rules, she must chase him and kill him, I mean her. Upon learning of his curse, she decides to marry him. She views Akane as a rival for the love of Ranma. She transforms into a cat when hit by cold water.

An admirer of Shampoo, or rather stalker. He can't get over the fact that Shampoo doesn't like him. He's far-sighted, for that reason, he wears glasses. Without them, he confuses people with objects and vice-versa. He is jealous of Ranma because Shampoo likes Ranma. So he sees Ranma as a bitter rival. His fighting style involves the mastery of the "Art of Hidden Weapons" in which can pull out a great assortment of objects hidden in his sleeves and use them as weapons. He turns into a duck when hit by cold water because of one of his backfired plans.

This old man is the master of Ranma's father. Despite his age, he is a huge pervert who takes joy in stealing bras and panties from girls locker rooms. He is an expert when it comes to the matial arts. He and Ranma fight often. His favorite move is the "Happo Fireburst" which is actually just a bomb of fireworks made by him.

She is the obnoxious sister of Tatewaki Kuno. She excels in rythmic martial arts gymnastics. Her motto is "All's Fair in Love and War", thus she enjoys winning by default or making her opponent unable to fight in the actual match. She falls in love with Ranma and views Akane as a Rival. Her title is "The Black Rose". She is called as such because she usually uses black roses to conceal paralyzing powder or sleep powder in her traps.

She was also engaged to Ranma. She is good at making okonomiyaki and applies this as well in fighting. She uses a huge spatula on her back to fight. Ranma previously thought of her as a boy because of her appearance. She is also another one of Akane's rivals.

She is the oldest sister of Akane. She does all the housework since their mother died. She is very kind to all. Unfortunately, she can be very oblivious of the events happening around her.

She is also an older sister of Akane. All she cares about is money and will try to extort cash from anyone. She makes business with almost anything. Her victims include Ranma and Tatewaki Kuno.
