I am not a native speaker of English. If I make a grammar or word choice error correct me please. Spelling errors are also possible but this work is spell-checked (British English – with the exception of the word "movies") and I have better spelling than many native speakers. Pronunciation errors would be much more probable because I have learned English by reading it more than by speaking it.
I have many ideas for stories that I will probably never write in full length. In chapter 1, I have presented my ideas for Ranma fanfiction based on existing fanfiction. In chapter 2 and 3, I will present my ideas for Ranma fanfiction that may be inspired or influenced by existing fanfiction but they are based only on Ranma½ or other original fiction. The shorter story ideas are in this chapter, the more detailed ones will be in chapter 3.

Ideas not based on another fanfiction (Senshi Troubles is influenced by existing fanfiction but (unlike story ideas from chapter 1) it doesn't use any existing fanfiction as a background story and it is different enough from existing fanfiction to be included in this chapter; I'm a boy! was my own idea but I have the name Kaneda from a similar fanfiction that I have read later; all the other ideas are completely original):
I'm a boy!
Type: AH
My idea, Kaneda's name inspired by Ron Dow75 (Ranma & Kaneda)
Kaneda Tendo is biologically female and his birth name was Akane but he dresses as a boy, binds his female breasts and acts in all aspects as a male. He is engaged to Ranma: a boy whose sex is determined by water temperature. How will this engagement work?

Ranma Shimeru
Type: XO, AU
My idea
Ranma is the son of Genma Saotome and Kahoru Iroka. Genma and Kahoru didn't marry and Kahoru has never told Genma her secret. Kahoru is from the Shimeru clan who change genders when they get excited. Genma knows Kahoru only in her excited form. Her relaxed form is male. Genma and Ranma sign the seppuku pact and leave before Kahoru remembers that she should warn Genma that Ranma will start changing genders. For the first 14 years of his life Ranma seems to be a normal boy but then he starts turning female when excited. He also becomes full time female for a week during every menstruation. Ranma manages to hide it from all of his classmates including Ryoga but there are many sightings of a red-haired girl near the boys school. Genma and Ranma visit Jusenkyo, Genma falls into the Spring of Drowned Panda and Ranma falls into the Spring of Drowned Girl but the curse doesn't turn Ranma into a normal girl. Ranma's cursed form is female when relaxed and male when excited. Jusenkyo curses aren't affected by menstruation but every Shimeru is locked in her/his female form during it and the curse has no visible effect on Ranma when he/she menstruates. Ranma was male at Jusenkyo and the curse changed him into a girl but she became male again while chasing Genma-Panda. Ranma stopped chasing him before meeting Ryoga but Genma didn't stop and the collision of Genma and Ryoga caused Ryoga's fall into the Spring of Drowned Little Black Pig. Ranma has forgiven Genma because the curse makes the gender-changing easier to manage.

Senshi Troubles
Type: XO
Inspired by Carrotglace, Ryo-Wolf and others
Luna has big problems: Sailor Moon is afraid of cats, Sailor Mercury is a blackmailing mercenary, Sailor Mars has a dangerous temper, Sailor Jupiter has a big spatula, Sailor Venus is a Chinese bimbo and Tuxedo Kamen is a delusional samurai wannabe.

Spring of Drowned Twins
Type: AH
My idea
Ranma's curse was split by the water of the Spring of Drowned Twins. When Ranma is splashed with cold water he becomes two persons – one boy (Ranma) and one girl (Ranko). When one of them is splashed with hot water while touching the other they merge. When they merge, their memories and experience merge too. When they separate, their minds are the same. Genma-panda brings Ranko to the Tendos and Ranma comes while Akane and Ranko are in the bath. Only Genma's curse is mentioned. Ranma is engaged to Akane but only Ranko goes to Furinkan High School and has to deal with Kuno. Ranma and Ranko merge every evening in the bath and separate before going to sleep. Ryoga falls in love with Ranko and not with Akane.

Unequal Genders
Type: AU
My idea
How would Ranma's life look like if he lived in a world that is similar to ours but there is the difference that one gender (male or female) has a serious handicap (like not being able to speak, see or eat solid food)?
T-T-T-T-T-T-T
World for Men
Type: AU
My idea
Men live in their own world but they are connected to the world of women by their penis. Jusenkyo exists in both worlds. Women and animals exist only in one world. Men cursed to turn into women or animals from the world of women are fully transported into the world of women by the curse and hot water transports them back. Men cursed to turn into animals from the world of men lose their connection with the world of women and this connection is restored by hot water.

World for Women
Type: AU
My idea
When girls are about 12 years old, they get a body in another world (the World of Women) that is internally connected to their old body. At first, it looks like a baby but when they are about twenty, it is fully grown up. Babies are born into the World of Women but they must go to the first world through the genital organs of their mother (or another woman) before they are five years old. If a girl stays in the World of Women, her second body starts developing inside her because there isn't any third world. Boys wouldn't have this problem but many vitamins are missing in local food (women get them from their first body and babies get them from breastfeeding). When Ranma becomes female, his second body appears in the World of Women. When he becomes male, the body disappears and when he becomes female again, it appears in the same place where it disappeared. Ranma meets Nodoka, Akane and Ukyo in this world before meeting them (again) in the first world.
