Another way is to create a conflict where the OC has to work with the heroes despite hating them. This can lead to some interesting character development for both the OC and the heroes. The OC could gradually learn to see the heroes in a different light, or the heroes could realize that they have been wrong in some ways. You can also add some mystery to the story. Maybe the OC has a secret power that the heroes need, and this forces them to interact. This power could be related to something that the heroes have been searching for, but they didn't expect it to come from someone who hates them.
Perhaps the concept of heroes in the fanfiction goes against the OC's values. For example, if the heroes use violence as a first resort and the OC is a pacifist, that could lead to a dislike. It could also be that the fanfiction portrays the heroes as always being right, and the OC, who may have a different perspective, is constantly marginalized.
One way is to show Bella's reactions whenever Christmas is mentioned in the fanfiction world. For example, she could roll her eyes or make sarcastic comments. This would immediately establish her dislike for Christmas - related fanfiction.
One way is to explore the magical interactions between them. For example, Harry could try to use his spells against Odin's divine powers and see what happens. This would add more action and tension to the story.
The character Oc can be developed by exploring his backstory. Maybe he had a different upbringing than Joker, which led him to have different values. For instance, if he was sent away to a boarding school while Joker was left behind in a tough neighborhood, this could shape his more refined and moral personality.
Well, they could start to communicate more. If Dawn realizes that Ash dislikes her and tries to have an open conversation with him, things might change.
One option is to simply avoid reading or engaging with Rias fanfiction. If the OC hates it, there's no need to subject it to that content.
The OC's powers could be developed through training with a Lucario. Since Lucario are known for their control over aura, they could teach the OC how to focus and strengthen their own aura-based powers. For example, by sparring with the Lucario, the OC can learn new attack techniques and improve their speed and strength.
You could start with the OC's origin. If they are from a different kingdom, describe what that kingdom is like. Is it a place full of magic like Corona? Or is it a more industrialized place? Then, talk about their family. Were they poor or wealthy? Did they have a big family or were they an only child? All these details can shape the OC's personality. For instance, if they were poor, they might be more resourceful and street - smart. You can also include events that led them to meet Rapunzel, like a quest or a journey they were on.
To develop the OC in an Infinity Gauntlet fanfiction, start with their initial state of mind when they first encounter the gauntlet. Are they curious, greedy, or cautious? As the story progresses, put them in situations where they have to rely on the gauntlet's powers. For instance, they might use it to save a loved one from a dangerous situation. This not only shows their love for family or friends but also how they are starting to understand the power they hold. Then, introduce moral dilemmas. If they can use the gauntlet to make themselves rich, but it would harm others, what do they do? These types of situations will slowly but surely develop the OC's character in a complex and interesting way.
OC could be developed by giving them a unique backstory related to the world of Bioshock. For example, they could be a descendant of an early Rapture scientist who was sent away before the fall. This would give them a connection to the place and a reason to explore it.
