Create complex relationships between your OC and the existing Arcobaleno characters. For example, if your OC has a love - hate relationship with one of the Arcobaleno, it will add a lot of drama and intrigue. Also, don't be afraid to put your OC in difficult moral situations, like having to choose between the safety of the Arcobaleno and the greater good.
Develop a really unique OC. Give them distinct personality traits, like being overly curious but also extremely cautious. Also, a unique backstory that ties into the world of the Arcobaleno in an unexpected way.
First, focus on creating a really unique OC. Give them a distinct personality, backstory, and appearance. For example, if your OC has a tragic past that led to their Persona awakening, it can make them more interesting. Second, tie their story into the existing lore of Persona 5 in an unexpected way. Maybe your OC discovers a hidden aspect of the Metaverse that the Phantom Thieves didn't know about. Third, use vivid descriptions, especially when it comes to the battles in the Metaverse and the manifestations of the Personas.
To make your Shanks OC stand out, focus on their backstory. Maybe they come from a small, forgotten island with a special culture that no one else in the One Piece world has seen. This could influence their values and how they interact with Shanks and his crew. Their goals should also be different. Instead of just wanting to be a powerful pirate, they could be on a quest to find a certain type of flower that only grows in the most dangerous parts of the Grand Line because it has a connection to their past. And don't forget relationships. If your OC has a complex relationship with Shanks, like being in love with him but also being his rival in some ways, it will make them more interesting.
Give your OC a distinct personality trait. For instance, if your OC is super optimistic in the face of every difficulty at PCA. This positive attitude will set them apart from other characters.
Create a distinct appearance. Instead of just having a regular human - like form, you could make your OC a combination of different Inkwell Isles creatures. Say, with the body of a frog and the wings of a dragonfly. The more unusual the appearance, the more it will stand out.
Use vivid and detailed descriptions. When describing Rumpelstiltskin, don't just say he's small and imp - like. Describe his tattered clothes in detail, the way his eyes glint with mischief. For the OC, describe their emotions and reactions in a more nuanced way. For example, when they first meet Rumpelstiltskin, they might be both terrified and fascinated at the same time. This will draw the readers in and make your fanfiction more memorable.
Give your OC a unique backstory. For example, if your OC has an elemental power, explain how they got it in a different way than the main characters. Maybe they got it from an ancient artifact instead of being born with it. Also, give them a distinct personality trait. If all the ninja are brave, make your OC brave but also really superstitious.
Develop a really unique and well - thought - out OC. Give them a distinct personality, backstory, and set of skills. For instance, an OC with a phobia that they have to overcome during missions can make for an interesting read.
Develop a really unique personality for your OC. Don't just make them a copy of existing characters. Give them quirks, like a strange fear of a certain type of magic or an obsession with collecting rare herbs.
Give your OC a unique personality trait. For example, if most characters in Riverdale are extroverted and bold, make your OC shy and introverted but with a hidden strength. This contrast will make them stand out. Also, give them a distinct appearance, like a particular style of clothing or a unique hair color.
Use detailed descriptions. When writing about your OC's world or their battles, be as vivid as possible. If your OC is in a fight, describe the movements of their keyblade, the sparks flying, and the emotions they're feeling. Also, explore different themes. Kingdom Hearts has themes of friendship, light vs. dark, and self - discovery. You can add new themes through your OC, like the idea of redemption for a character who has made mistakes in the past.
