How can I make my 'Lucifer Morningstar x OC fanfiction' stand out?

Focus on character development. Make your OC have unique traits and backstory that interact well with Obito's character. For example, if your OC has a strong sense of justice, it can contrast or complement Obito's more morally ambiguous actions.

Focus on character development. Give your OC a distinct personality, backstory, and goals. For example, if your OC has a troubled past that affects how they interact with Digimon, it will make the story more engaging.

Create a unique backstory for your OC. Give them a motivation and a history that ties into the Dragon Ball universe in an interesting way. For example, if your OC has a vendetta against a certain villain that Kefla has also faced, it can create an instant connection between them.

Give your OC a unique backstory. For example, if they come from a strange or mysterious place, it will make them more interesting. Also, give them a distinct personality trait like being extremely shy but super competitive when it comes to the Running Man games. Another way is to give them a special skill or ability that no one else in the Running Man world has.

Use dialogue effectively. Have Darly and the OC have conversations that are not just about their feelings but also about their views on the world, how to deal with threats, and their hopes for the future. This will make their relationship seem more real. Also, add some mystery to the OC. Don't reveal everything about them at once. Let the readers be curious and keep reading to find out more about the character.

Incorporate real historical events into the story. Since 'Rurouni Kenshin' is set in a historical context, adding details about the Meiji Restoration or other relevant events can make the story more immersive. Also, focus on the character development of both the OC and Kenshin. Show how they change and grow because of their interactions.

Play with the relationships. Instead of just having the OC be a sidekick, create complex relationships. Maybe the OC has a romantic interest in one of the Sailor Scouts' enemies, which causes a rift in the group at first but then leads to a deeper understanding of the enemy's motives and a new way to defeat them. It's all about adding unexpected twists and turns to the story.

Develop a really unique OC. Give them distinct personality traits, like being extremely shy but having a hidden fierce side in battle. Also, create a detailed backstory for them that ties into the Naruto universe in an interesting way.

Create strong relationships between your OC and the existing characters. Don't just have them tag along. Have them interact in meaningful ways, like having deep conversations, sharing secrets, or having conflicts that are resolved in an interesting way. This will make your OC more integrated into the story.

First, develop a really unique character design for your OC. Give them distinct physical features, like a troll with glowing crystals on their body or a human with a strange birthmark that has a connection to the troll world. Second, focus on an original plot. Don't just follow the typical good - vs - evil story. Maybe your OC has to solve a mystery that involves both troll and human cultures. Third, use vivid descriptions. When you describe the troll world or the actions of your OC, make the reader feel like they are there.
