A wind - up mouse could be a potential character. It's always scurrying around and stumbles upon the toy lemon by accident. Then there could be a wise old toy owl that gives advice to the other toys about the significance of the toy lemon. And a bouncy rubber ball that adds some fun and energy to the group of toys in the fanfic.
Obviously, Kushina herself would be a central character. Minato could also be an important character as he is likely to be the father. Her friends, like Mikoto, could be there to support her throughout the pregnancy. Also, the medical ninjas in the village who take care of her during the pregnancy would be part of the story.
A possible set of characters could include a healer in a Pokemon village. Salazzle gets injured and is brought to this healer. The healer, who has a gentle and kind heart, takes care of Salazzle. There could also be some of the village elders who are skeptical about having a Salazzle around. And a wandering adventurer who passes through the village and has some knowledge about Salazzle's rare abilities, which helps the healer and the village deal with Salazzle in a better way.
Well, there could be doctors like Dr. Smith, a brilliant surgeon. Nurses such as Nurse Johnson, who is very kind but strict about following procedures. There might also be patients like Mr. Brown, a friendly old man with a heart condition. And don't forget the hospital administrators like Ms. Davis who is always trying to keep the hospital running smoothly.
Mike and Sulley could be great main characters in this kind of fanfiction. They could get involved in a lemon - themed adventure on campus, like searching for a rare lemon - flavored monster treat that is said to give special powers to whoever eats it.
It could be a young orphan. Orphans often struggle to find a place where they belong, so this character would have a strong motivation to search for that special place. They could be kind - hearted but also have a bit of a feisty side to survive in the world of the fanfic.
Jackie Estacado from 'the darkness' is an obvious choice. His connection to the Darkness power makes him a central figure and his skills and personality can drive the story forward in a crossover.
Obviously, Percy is the main character. There could also be some native Alaskan characters, like an Inuit elder who gives Percy some valuable advice or a young Alaskan hunter who becomes Percy's friend.
Tsunade might also play a role. She could suspect Naruto of having a secret life and start an investigation. And of course, Orochimaru could be involved as well, either trying to use Naruto's secret for his own gain or being a part of the mystery that Naruto is trying to solve in his secret life.
Obviously, Ranma and Akane are prime candidates. Their relationship is central to the series, so a pregnancy between them would create a lot of drama and interesting storylines. Shampoo could also be involved in some way. Maybe she's jealous and tries to interfere, or she could be surprisingly helpful. Genma, Ranma's father, would also play a role. He might have some old - fashioned or comical ideas about the situation.
Obviously Naruto as the main character. Sasuke could be there, and his relationship with Naruto might change due to Naruto's new identity. There could also be characters from the underworld, like minions of Hades or other mythological creatures.
