You can give your character a unique backstory. For example, if your character is from a different country but has a strong connection to the ideals that Captain America represents. Maybe your character has a family history of standing up against tyranny in their homeland. Another way is to give your character an unusual skill or ability. It could be something like being able to communicate with animals, which might come in handy during missions in unexpected ways.
One way to make your self - insert character unique is through their motivation. For instance, while Captain America fights for justice and freedom in a broad sense, your character could be fighting for a very personal reason. It could be to avenge a loved one who was killed by the enemy. Additionally, your character could have a different cultural background that influences their perspective. They might approach problems and solutions in ways that are different from the other characters in the fanfiction, which would make them stand out.
Give your self - insert character a unique hobby. For example, if you make them a collector of rare sea shells. This could lead to interesting interactions with Nami, as she might be interested in using these shells for navigation or just be curious about their beauty. Also, give them a distinct personality trait like being extremely superstitious. This would contrast with Nami's more practical nature and create some fun and comical moments in the fanfiction.
Create a new kind of magic or ability for your self - inserted character. In Warcraft, there are already many types of magic like arcane, fel, and nature magic. But if you come up with something like a 'chronomancy' that deals with time manipulation, it can set your story apart. You can then explore how this new power affects the existing power dynamics in Azeroth.
One idea could be inserting yourself as a new recruit in the Howling Commandos. You could have a special skill, like being an expert in decoding enemy messages. Then, you get to interact with Captain America and the team, facing challenges together and forging strong friendships. Another plot could be that you are a scientist in the same era as Steve Rogers. You accidentally discover a new element that could enhance the super - soldier serum. This draws the attention of both Captain America and the bad guys, leading to a race to protect or steal your discovery.
A great way to make a unique character is to give them a special ability or weakness that is related to the Omnitrix. For example, they might be able to sense when the Omnitrix is about to run out of energy. Or their weakness could be that they get really sick every time they transform into a certain type of alien. This kind of detail will add depth to your character in the Omnitrix self - insert fanfiction. You can also base their character on a combination of different existing characters from the Omnitrix universe, but with a new twist.
Give your character a distinct appearance. For example, a unique hairstyle or a piece of clothing that has a special meaning. This will make them visually stand out among the other characters in the story.
To make it unique, focus on the character's backstory. Instead of the typical 'orphan turned Sith' story, give your self - insert a complex past from our world. Maybe they were a scientist who was obsessed with the concept of power, and that led them to the Sith. Also, create new Sith powers or abilities that are specific to your character. This will set your fanfiction apart from others.
First, think about their semblance. It should be something that fits within the RWBY universe's rules of magic and power. For example, if it's a power related to nature, explain how it interacts with the existing Grimm and Dust in the world. Then, consider their backstory. Maybe they grew up in a small village on the outskirts of Vale that was constantly under threat from Grimm. This would shape their personality as someone who is tough and determined.
First, think about your character's backstory. For example, where they come from, their family situation. Then, consider their special abilities or skills that would make them stand out in the Percy Jackson world. Maybe they have a unique power related to water like Percy, but with a different twist.
They could stand out by their backstory. If they come from a different part of the non - magical world or have a really strange family history related to magic. Say, their family was once part of a secret dark magic cult but they didn't know until they entered the wizarding world. This would give them a different perspective and make them stand out. Also, their attitude towards the existing power structures in the wizarding world, like being very critical of Dumbledore's decisions from the start, would make them distinct.
By changing key events. For instance, if the self - insert is present during a major battle, they could make a different decision than the original characters, which might lead to a different outcome for the battle and subsequent events in the story.
