First, develop your OC well. Give them a unique backstory, powers, and personality. For example, if their magic is related to nature, explain how they discovered it. Then, make sure your story fits within the Young Justice universe. Know the existing characters and the overall tone. Don't make your OC overpowered to the point it's unrealistic.
In this type of fanfiction, magic could play a role in character development. For Naruto, experiencing a different type of power system like magic in the Young Justice world could make him question his own ninja way. He might start to adapt some of the magic concepts into his own fighting style. And for the Young Justice characters, learning about Naruto's 'magic' (chakra) could open their eyes to new ways of thinking about power and how to use it more effectively.
Well, Tumblr can be a great place too. There are many Young Justice fans on Tumblr who create and share their own fanfictions or reblog interesting ones with magic OCs. You can search relevant tags like #YoungJustice #MagicOC #Fanfiction. Also, some Reddit communities related to Young Justice might have some hidden gems in terms of such fanfictions.
The appeal lies in the freedom to create. With an OC, you can shape a character exactly as you want. You can give them a backstory, motives, and relationships that are unique. When paired with Superboy, it can lead to some really interesting storylines.
How about a villain named Shadowstrike? He's an assassin with shadow - based powers. He was trained in a secret organization but turned against them. In the Young Justice fanfiction, he could target the heroes because they represent the establishment that he hates. He can move through shadows and use them to surprise his opponents.
In Young Justice Superboy and OC fanfiction, character development is key. The OC can be used to highlight different sides of Superboy. Maybe the OC has a troubled past, and through their interactions, Superboy learns more about himself and his own humanity. Fanfiction gives the opportunity to dig deeper into the emotional aspects of these characters.
A common motivation could be revenge. For example, if the OC villain was wronged by a hero or an organization in the past, they would seek revenge. Maybe their family was killed during a superhero battle and they hold all heroes accountable.
One aspect to consider in Young Justice Cheshire x OC fanfiction is the character dynamics. The OC (Original Character) has to be well - developed to interact believably with Cheshire. For example, if the OC is a hero, there will be a natural conflict with Cheshire who is often on the villainous side. The story could explore how their relationship evolves over time, perhaps starting from mutual distrust to a more complex understanding. Another point is the setting within the Young Justice universe. The fanfiction should adhere to the general rules and lore of this world, like the existence of different superhero teams and their modus operandi. This helps to ground the relationship between Cheshire and the OC in a familiar context for fans of the series.
One idea could be that Naruto is somehow transported to the Young Justice universe and his chakra is mistaken for a form of magic. This could lead to some interesting team - ups and misunderstandings as the Young Justice characters try to figure out who Naruto is and what his 'magic' can do.
A more complex approach could be to introduce a new threat to the Young Justice universe that is specifically related to cybernetic technology. Your Cyborg OC, with their unique knowledge and abilities, would then be crucial in dealing with this threat. This not only inserts your OC into the story but also creates a new and exciting storyline that can explore different aspects of the Young Justice world and your OC's character.
