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.
Another possibility could be an original antagonist created specifically for the fanfiction. For example, a powerful sorcerer from a hidden dimension who sees the OC's rebirth as a disruption to the natural order of the MCU universe. This sorcerer could try to eliminate the OC and use their power for their own dark purposes. They might be able to manipulate magic in ways that even Doctor Strange hasn't seen before, making them a formidable foe.
Not always. While the MCU draws inspiration from the comics, there are often changes and adaptations made to fit the cinematic universe and modern audiences.
They contribute in several ways. Firstly, they keep the fans engaged between movie releases. They also introduce new concepts and ideas that might later be incorporated into the movies. For instance, some new villains or plot twists can first be tested in the graphic novels. Also, they can provide different interpretations of the characters, adding more dimensions to the overall MCU franchise. Moreover, they can attract new fans who are more into reading graphic novels rather than just watching movies.
The origin stories give depth to the characters. Captain America's origin, with his roots in World War II, adds a historical and moral weight to the MCU. His values shape his actions and influence other characters. Also, his origin story allows for interesting time - travel and alternate - reality plotlines later in the MCU.
Captain America's origin story is quite interesting. Steve Rogers was a weak but very brave and kind - hearted man. He was selected for an experiment to create a super - soldier during World War II. The experiment transformed him into the strong and patriotic Captain America. His origin is deeply rooted in the war - time context and the need for a symbol of hope.
There's a good chance they will. Comic Con is a major platform for promoting and generating buzz for upcoming MCU films and shows. But it depends on their schedule and promotional plans.
