I'm not sure specifically as it could be a very niche or unique fanfiction. It might be a story where the Naruto character is somehow associated with the concept of 'zer0', perhaps in a new power or identity context.
Zer0 crossover fanfiction is a type of fan - created writing that combines the character Zer0 from a particular source (like the Borderlands series) with elements from other universes or stories. It allows fans to explore new and interesting scenarios by mixing different fictional worlds.
Zer0's backstory also contributes to his appeal in harem fanfiction. Since he has a somewhat unclear past, it leaves room for the fanfiction writers to explore and create different scenarios. In a harem context, this can lead to some really emotional and deep - rooted relationships. The harem members can be the ones who gradually help Zer0 come to terms with his past or vice versa, creating a complex and engaging web of relationships.
One example could be a crossover where Zer0 ends up in the world of "The Lord of the Rings" and has to deal with orcs and hobbits. Another might be a story where Zer0 crosses over into the "Mass Effect" universe and teams up with Commander Shepard. There could also be a crossover with a horror - themed universe like "Resident Evil", where Zer0 has to fight zombies and bio - organic monsters.
One popular Borderlands Zer0 x Harem fanfiction is 'Zer0's Unusual Allies'. It shows Zer0 gradually forming a unique bond with a group of characters in a harem - like situation. The story has great character development and action scenes.
One common theme is adventure. Since Borderlands is an action - filled world, many fanfics have the reader and Zer0 going on exciting adventures together. Another theme is loyalty. They often face difficult situations that test their loyalty to each other.
In my opinion, a great Zer0 x Angel fanfic would incorporate the unique lore of Borderlands 2. The world is full of strange creatures, interesting technology, and a rich backstory. If the fanfic can weave this lore into the relationship between Zer0 and Angel, it would be really good. Also, good writing style is important. Vivid descriptions and realistic dialogue can bring the characters to life and make the story more immersive. For instance, if it can show Zer0's silent but deadly actions and Angel's more vocal and guiding personality through their conversations and actions in the story.
You can try fanfic websites like Archive of Our Own (AO3) or FanFiction.net. These platforms usually have a large collection of fan - made stories, including ones about Zer0 and Angel from Borderlands 2.
Some popular 'Borderlands Zer0 x Reader fanfic' include 'Finding Zer0'. In this one, the reader embarks on a journey to find Zer0 after he goes missing. 'Zer0's Promise' is also good. It shows how Zer0 makes a promise to the reader and how they both strive to keep it throughout various challenges in the Borderlands.
