A really interesting plot would be if Balalaika gets cursed by a voodoo priest in Roanapur. As a result, she starts to see hallucinations of her dead comrades and is forced to confront her past traumas. To break the curse, she has to perform a series of tasks that go against her nature, like showing kindness to her enemies. This would be a great way to explore her character in a new light and also introduce some supernatural elements into the Black Lagoon universe.
Another plot could involve Balalaika having to protect a valuable artifact that has some connection to her past. This could draw her into a conflict with other powerful factions in Roanapur, all while she is haunted by the memories associated with the artifact. Maybe it was something she lost during a war and now she has a chance to regain it, but at great risk.
Balalaika is such a complex and fascinating character. In my fanfiction, I would start with her past, exploring how she became the tough and feared leader she is. Maybe she has a secret mission that takes her back to her homeland, and along the way, she meets an unexpected ally who challenges her views and makes her question her loyalty to her current organization.
The fanfiction could also delve into how Balalaika and Eda view the world of 'Black Lagoon'. Balalaika, who has a more structured view due to her military upbringing, and Eda, who has seen the seedy underbelly from a different perspective. Their different worldviews could cause conflicts or alliances as they navigate the dangerous world of crime and violence in the story.
Perhaps a fanfiction could focus on Shenhua's past. Show how she became the skilled fighter she is in the present. It could involve her training under a strict master in a remote location and the events that led her to the Black Lagoon area.
A more complex plot could be that there is a prophecy in both universes about a combined force of a shinobi and a powerful figure like Balalaika. Naruto and Balalaika are brought together by this prophecy and must figure out how to fulfill it while dealing with the cultural differences and political intrigue in both their worlds.
A great Black Lagoon Balalaika fanfic often has a deep understanding of her character. It should capture her tough and no - nonsense personality. For example, showing her strategic mind in handling the Russian mafia business.
Balalaika is often portrayed as a powerful and intimidating figure. In fanfiction, she could be the driving force behind a major plotline involving Eda. Maybe she recruits Eda for a special task that only Eda can do because of her connections in the underworld.
One idea could be exploring their past before they became the way they are in Black Lagoon. Maybe a story about their life in the facility where they were experimented on, and how they first started to form their unique bond.
One idea could be that the creature forms an unexpected alliance with a local scientist who wants to protect the lagoon from being exploited. They work together to fend off greedy developers.
One idea could be exploring the backstories of the mercenaries in more detail. For example, delving into how Revy became such a skilled fighter. Another could be creating a new mission for them that involves a powerful and mysterious enemy. Maybe a shadowy organization that has ties to their pasts.
Another plot could involve the two universes being on a collision course because of some interdimensional rift. Ghost Rider and the main characters of Black Lagoon must work together to close the rift while also dealing with the threats that come from both worlds merging. There could be a lot of action and character development as they learn to trust and rely on each other in this strange situation.
