Another possibility is a conflict within the group. There could be misunderstandings or power struggles. For instance, if some of the Sailor Scouts start to question Sailor Moon's leadership or decisions too often, it could lead to her feeling alienated and ultimately deciding to leave.
There could be a plot where Sailor Moon loses her memory and the other Sailor Scouts have to help her regain it while still fighting off villains. They might use their unique powers in creative ways to jog her memory. For example, Sailor Venus could use her love - based powers to trigger memories related to her friends and allies.
Well, they might go on a new adventure together. Maybe face a new enemy that wasn't in the original series. They could also have some really deep conversations about their powers and responsibilities.
Often, the story becomes darker. The Sailor Scouts are left without their leader, so they may struggle at first. They might start to doubt themselves and their abilities. Meanwhile, Sailor Moon might be on her own journey of self - discovery, facing challenges that test her strength and resolve without the support of her friends.
Another option is to check out some Sailor Moon - focused forums. Sometimes, fans will share their own 'dark sailor scouts fanfiction' or recommend stories they've found elsewhere on these forums.
One good 'dark sailor scouts fanfiction' could be one where the dark sailor scouts have to face an even greater evil that forces them to team up with the regular scouts. This could lead to interesting character developments as they overcome their differences.
The Scouts could use their combined powers. Sailor Moon might use her Moon Healing Escalation to break free from any bindings or barriers Jadeite has put in place. The other Scouts could also contribute their powers to create a distraction or a force field to protect themselves while they escape.
Maybe in the fanfic, there's a war for control of a powerful energy source located in the outer planets. The Sailor Warriors of the outer planets are in a race against an unknown force. Sailor Uranus and Sailor Neptune are on a reconnaissance mission to find out more about this enemy. Meanwhile, Sailor Pluto is guarding the time - space gateway to prevent any surprise attacks from other timelines. Sailor Saturn is in a state of waiting, as her power is too great to be unleashed without proper consideration, but she's ready to act when the situation calls for it.
Overall, Haruka's desire to be a man will likely cause some initial shockwaves in her relationships with the other Sailor Scouts. But as they are a group that values friendship and understanding, they will most likely end up accepting her and standing by her side. It could also lead to some of the other Scouts exploring their own ideas about gender and identity more deeply as a result of Haruka's journey.
Sailor Uranus might become more open about her feelings. In a war situation, she would have to rely on her teammates more, and this could break down some of her tough - exterior walls. For example, she might show more vulnerability to Sailor Neptune. Sailor Neptune, in turn, could develop a stronger sense of leadership. She has always been intelligent and calm, and in a war, these qualities could put her in a leading position among the outer planet Sailor Scouts.
