Monkey Fist is often a popular choice. His villainous nature and his connection to martial arts and ancient artifacts can add a lot of intrigue to a time - travel based fanfiction. He could be chasing Kim and Ron through different time periods, trying to steal some powerful relic.
One idea could be that Kim and Ron get stuck in a time loop within a particular historical event. They have to keep reliving the same day until they figure out how to correct an anachronism that's disrupting the time - space continuum. Another could be that they travel to the future and see versions of themselves that have changed in unexpected ways due to different life choices.
Their relationship could develop more quickly in the fanfiction. For instance, during the 'Sitch in Time' events, they might have a moment of realization where they understand their feelings for each other more deeply due to the high - stakes time - traveling situation. They could start to act more like a couple earlier than in the original story.
Maybe in the fanfiction, Kim and Ron find a hidden power within the time - traveling device during 'Sitch in Time'. This power allows them to visit different key moments in their past adventures but also attracts the attention of a new villain who wants to steal this power for their own evil plans. So they have to protect this power while still trying to fix any disruptions in time.
Perhaps in this fanfiction, Kim might lose some of her powers during the time - traveling adventures in 'a sitch in time 2'. She then has to rely on her wits and the help of her friends like Ron and Rufus in a more creative way. For example, she might use her knowledge of history to outsmart the bad guys instead of just relying on her usual martial arts and gadgets.
There could be a time - guardian character. This character could be an ancient being that has been protecting the timelines and appears to help Kim understand the true nature of time - traveling and the rules she must follow to set things right.
One big challenge is their own immaturity. They are still young and might not be fully ready to be parents. Emotionally, they'll have to deal with the stress of a new relationship dynamic. Financially, as I said, it's a huge issue. They'll need to figure out housing too. And education for the child in the future is another thing to worry about. They'll also have to face the possible judgment from their peers and the community at large.
No. Fanfiction involving sexual content is not appropriate. It goes against ethical and moral standards, especially when it involves characters like Kim and Ron who are often associated with younger audiences in their original shows.
One common theme is their relationship. Whether it's about them falling in love or strengthening their friendship. Another theme could be adventure. Since they are from an action - oriented series, fanfictions often take them on new adventures.
In fanfiction, 'Kim Possible Ron and Betty' can be used to create various storylines. It might explore different relationships between the characters. For example, it could be about how Ron and Betty interact within the Kim Possible universe, perhaps in a new adventure or a different take on their existing relationships.
