One idea could be that Broly somehow ends up in the world of Black Lagoon. He might initially be seen as a huge threat by the Lagoon Company. But as the story progresses, they realize his power can be useful against their common enemies. For example, when facing powerful crime syndicates or military forces that are too much for them to handle alone.
One idea could be that Naruto and his team are sent on a mission to the world of Black Lagoon. They team up with Rock to take on a powerful crime syndicate that is after a powerful jutsu Naruto has. Another could be that Revy gets transported to the Naruto universe and has to deal with the shinobi world's politics while also teaching some of the younger ninjas her combat skills.
I think Hinata and Balalaika would make for a really interesting pairing in a Naruto Black Lagoon crossover fanfiction. Hinata is shy and gentle, while Balalaika is a powerful and intimidating crime boss. Their interactions could be really fascinating as Hinata tries to understand Balalaika's world and Balalaika might be a bit bemused by Hinata's innocence. Also, Kakashi and Dutch could be a great pair. Kakashi's calm and strategic mind would work well with Dutch's leadership skills in the Lagoon Company.
One great Naruto and Black Lagoon fanfiction is 'Ninja in the Lagoon'. It combines the unique ninja elements from Naruto with the gritty underworld of Black Lagoon.

One interesting Naruto Black Lagoon fanfiction could be about Naruto ending up in the world of Black Lagoon. He might use his ninja skills in the lawless world of Roanapur. For example, his shadow clone jutsu could be used to create distractions during a gunfight, which would be a really cool combination of the two universes.
One idea could be Naruto being transported to the world of Black Lagoon. He might use his ninja skills in the gritty and dangerous underworld. For example, his shadow clone jutsu could be used for various heist strategies or in combat against the many dangerous foes in the Black Lagoon world.
Naruto himself is a very popular character to include. His unique powers and personality can add a lot to the stories. Also, Revy from Black Lagoon is often included. Her bad - ass nature and excellent gun - fighting skills make for great interactions with the Naruto characters.
Well, Naruto's Rasengan could be used as a powerful attack in the Black Lagoon world. Imagine him using it to take on a group of heavily armed mercenaries. His chakra control could also be used in stealth situations, like sneaking past security systems in the criminal underworld.
Roberta in fanfiction is usually a complex character. She is torn between her loyalty to her former masters and her newfound friendships in the Black Lagoon world. In some fanfictions, like 'Roberta's Dilemma', this internal struggle is the main focus, showing her as a character full of contradictions.
Well, Broly is extremely powerful and has a short temper. The characters in Black Lagoon are tough but not on Broly's level. So, there would be a lot of tension at first. For instance, Revy from Black Lagoon is used to being in control in a fight, but Broly would completely overpower her. This would create a power struggle within the group.
