In a fanfiction, their characters could also develop emotionally. Zero, who is often stoic, could start to show more vulnerability around Lilith. And Lilith, who is strong - willed, could learn to be more patient and understanding. This could be shown through various interactions like when they face difficult decisions or when they are in the middle of an intense battle and have to rely on each other not just physically but also emotionally.
For Zero, his development could focus on his social skills. Since he's often a lone wolf, being around Lilith could make him more open and communicative. For example, he could start to crack jokes or share more of his past experiences with her.
One possible storyline could be them teaming up to take on a new and powerful enemy in the Borderlands. Maybe a new kind of Hyperion mech that has some unique abilities. They could start off not trusting each other fully, but as the battle progresses, they learn to work together better and form a deeper bond.
To develop their characters, you can focus on their backstories. For Scorpion, explore his past as a ninja and how his thirst for vengeance has shaped him. Show how he starts to question this vengeance when he interacts with Sub - Zero. For Sub - Zero, you can delve into his loyalty to his clan and how that conflicts with his relationship with Scorpion. As the story progresses, have them learn from each other's strengths and weaknesses. For example, Scorpion could learn discipline from Sub - Zero, and Sub - Zero could learn about passion from Scorpion.
It could be about Naruto being summoned to the Borderlands by some strange magic or technology. Once there, he meets Lilith and they start to fight together against the bandits and other threats. Naruto's ninjutsu would be really cool to see in the Borderlands setting.
One common theme is the clash of different powers. Naruto has his chakra - based abilities like the Rasengan, while Lilith has her Siren powers. Fanfictions often explore how these powers interact when they are in the same situation. For example, in a battle scenario.
Another way to find good 'Borderlands Lilith x Naruto' fanfiction is by asking in relevant fan communities. There are forums dedicated to Borderlands and Naruto separately, and you can post a request for fanfictions that combine these two characters. Fellow fans might be able to recommend some hidden gems that you wouldn't find through normal search engines.
You could also develop their characters through their interactions with other characters. Zero's relationships with other vampire hunters or his classmates could influence how he behaves with Kaname. And Kaname's interactions with other Purebloods could affect how he approaches Zero. For example, if Kaname has to deal with a Pureblood who is jealous of his relationship with Zero, it could bring out new aspects of his character.
One possibility could be that Naruto finds himself transported to the Borderlands world and teams up with Lilith. Maybe Naruto's unique abilities like the Rasengan would be a great asset in the combat - filled Borderlands. His speed and strength could help Lilith in her battles against the various enemies in that universe.
A simple plot could be that Noble Six is lost in the Borderlands and Lilith finds them. Lilith decides to help Noble Six get back home. Along the way, they encounter various threats like the Hyperion forces or some dangerous wildlife. They have to use their combined skills to survive.
Their relationship can be developed through shared experiences. For example, going on dangerous adventures together. When they face life - threatening situations, they'll learn to trust and rely on each other more. Another way is through communication. If they open up about their pasts, fears, and dreams, it'll bring them closer.
Writers can develop Axton by focusing on his military past. For example, they can show how his training affects his decision - making during missions with Lilith. His loyalty to his comrades and his sense of duty can be explored further. For Lilith, her Siren powers can be developed more in - depth. Writers can create scenarios where she discovers new aspects of her powers while working with Axton. Maybe she can use her powers in ways she hadn't thought of before, which Axton's strategic mind helps her realize.
