An 'oc' can fit into the Disney universe by having a backstory that ties into the existing lore. For instance, if it's a 'Beauty and the Beast' fanfiction, the 'oc' could be from a neighboring village that has always had a strange connection to the enchanted castle. This connection can be explored through interactions with Belle and the Beast.
An 'oc' can be integrated into the Disney universe by having a relationship with an existing character. In a 'Toy Story' fanfiction, an 'oc' could be a new toy that was created by the same company as Woody. This connection allows the 'oc' to enter the world of the toys in Andy's room and have adventures with them.
It would be a darker universe. The villains' victories would mean that their cruel and self - centered desires are fulfilled. For instance, Gaston might have taken over Belle's village and turned it into a place full of his own statues and hunting grounds.
The OC could be a new hero from a different part of the world. For example, if they come from a small, technologically advanced country, they could bring a fresh perspective to the Marvel universe. Their skills and abilities could complement Spider - Man and Iron Man. They might start by helping out in local problems in their home country and then get noticed by the two heroes, eventually joining them in bigger battles.
Naruto could be a sort of protector or helper in the Disney princesses' world. Maybe he arrives just in time to save Sleeping Beauty from Maleficent's new evil plan. And in terms of the 'lemon' part, it could be that Naruto has some strange cultural misunderstandings. He could think that the princesses' ball gowns are some sort of ninja - like uniforms and try to add his own 'improvements' to them, creating some really funny and unique situations.
The OC could also fit in through their personality. If they are really outgoing and positive, they can boost the team's morale. Or if they are more of a calm and collected type, they can help keep the team level - headed during tough situations. They can form unique friendships within the team based on shared interests or values, which helps integrate them into the group.
Mickey Mouse would be a great fit. He's a classic Disney character and his leadership skills could match up well with the Power Rangers' leadership within their team. He could use his charm and quick thinking to help the Rangers in tricky situations.
They add depth by showing that there are complex emotions and situations. For example, in Beauty and the Beast, the Beast's past and his curse give a darker undertone. It makes the story more than just a simple love story as it shows the consequences of pride and rudeness. This adds realism and makes the Disney universe seem more multi - faceted.
The OC could be a descendant of a minor god or goddess that hasn't been explored much in the Percy Jackson universe. For example, a descendant of Hecate. This would give the OC powers related to magic and the ability to interact with the supernatural in unique ways that tie into the existing mythology.
Disney could issue statements firmly distancing themselves from such fanfiction. They can remind fans about their official values and the intended nature of their characters.
A Winged OC can fit in as a new ally. For instance, if the TMNT are facing a foe that has an aerial advantage, the Winged OC can use their flight abilities to even the odds. They could also be a source of new knowledge, like knowledge about a hidden part of the city that can only be reached by flying.
A Dragonborn OC can fit into the RWBY universe by having their own unique backstory related to dragons. For example, they could have been born in a world where dragons were both feared and revered. When they enter the RWBY universe, their dragon - like abilities such as enhanced speed, strength, and the ability to breathe fire or ice can make them stand out. They could become a new type of huntsman or huntress, using their powers for good.
