One way to create a Kryptonian OC (Original Character) in MCU fanfiction is to first understand the basic traits of Kryptonians in the DC lore. Kryptonians are known for their super strength, flight, heat vision etc. In an MCU context, you could blend these traits with the existing MCU universe's rules. For example, how would a Kryptonian's powers interact with the Infinity Stones? Maybe your OC could be a Kryptonian who was sent to the MCU universe by some cosmic accident. Their journey could involve learning about this new universe while also trying to hide their true identity as they are far more powerful than most beings there.
To incorporate a Kryptonian OC into MCU fanfiction, look at the existing power hierarchy in the MCU. Your Kryptonian OC would be very powerful, so how does that fit in? They could be a game - changer in battles. Also, think about their cultural background. Kryptonians have their own language and customs. How would that play out in the MCU? Maybe they introduce some new technology or knowledge from Krypton. This could attract the attention of characters like Tony Stark or Bruce Banner. Their presence could also disrupt the balance of power in the MCU, leading to new storylines and character developments.
One interesting MCU OC fanfiction could be about an OC with the power to manipulate time who teams up with the Avengers during the Endgame battle. This OC could use their power to reverse some of Thanos' actions in a unique way.
Well, the plot could involve the OC being reborn with some special powers. Maybe they're reborn as an Asgardian but with a unique twist. They could then interact with the existing MCU characters like Thor or Loki, and get involved in their adventures, perhaps helping to stop a new threat to Asgard or even all of the Nine Realms.
An interesting MCU OC fanfic idea could be an OC who is a journalist. They are always on the hunt for the next big story about the superheroes. This could lead them into all sorts of dangerous situations as they try to get exclusive interviews or expose secrets. Another could be an OC who is a mutant in the MCU (even though mutants are not as prominent yet). This OC would have to deal with being different and feared, while also trying to use their powers for good. And a third idea is an OC who is a reformed villain. They were once on the wrong side but now want to make amends and help the heroes in their fight.
There are mcu male oc fanfics that focus on the character's origin story. Maybe he's an alien who crash - landed on Earth long before the events of the movies. His struggle to fit in and understand human culture while hiding his true identity can make for a really engaging fanfic. He could then get involved in MCU events in unexpected ways.
First, give your male OC a unique backstory. It could be related to an event in the MCU. For example, if he's from Asgard, his story might involve the fall of Asgard. Second, define his powers or skills. Maybe he has the ability to manipulate energy like Doctor Strange but in a different way. Third, give him some flaws. No one is perfect, and this makes the character more relatable. For instance, he could be overconfident at times, which gets him into trouble.
One interesting MCU SI OC fanfiction could be where the self - insert (SI) character has unique powers and teams up with the Avengers in unexpected ways. For example, an SI with the power to manipulate time might help prevent Thanos from getting the Infinity Stones in the first place.
First, create your original character. Decide on their appearance, powers (if any), and personality. For example, if your OC has super strength, think about how they got it. Then, think about where in the MCU timeline your story will take place. You could start right after the events of 'Civil War' for example.
One idea could be creating a male OC who is a brilliant scientist from a small town. He discovers a new form of energy that attracts the attention of Tony Stark. Another could be a male OC with super speed who has to hide his powers until he's forced to use them to save a city. Maybe a male OC who is an alien prince stranded on Earth and has to learn about human culture while also trying to find a way back home.
