Black Widow is also a great character to focus on. Her past as a spy and her relationship with Hulk are interesting aspects. Fanfiction could explore her feelings towards her teammates and how she copes with the new threats in 'Avengers Age of Ultron'. Maybe a story about her training the new recruits or something related to her secret agent skills.
Vision is definitely an interesting character. His unique origin as a combination of JARVIS, the Mind Stone, and Tony Stark's creation makes for a lot of potential exploration. Wanda Maximoff is also great. Her powers are complex and her backstory of loss and revenge can be delved into deeper. And of course, Ultron himself. His view of humanity and his extreme measures to 'save' the world can be examined from different angles.
Definitely the Avengers as a whole. However, some fanfictions might also put a spotlight on Jarvis or Vision. Jarvis was important in the lead - up to Ultron's creation, and Vision was a key part of the solution to the Ultron problem. So, their roles could be expanded and their characters more fully developed in the fanfiction compared to the movie.
It can also be frustrating at times. Some fanfictions lack the proper understanding of the movie's lore. They might introduce concepts that don't fit well with the established Marvel Cinematic Universe. But on the positive side, many fanfictions are a labor of love. Authors pour their passion for the movie into their writing, and that can really shine through, especially when they capture the essence of the characters as we know them from the movie.
Well, one reaction could be excitement. Fanfictions often explore different aspects of the characters and storylines that might not have been fully delved into in the movie. For example, they might focus on the relationships between the Avengers in more depth, like the budding romance between Black Widow and Hulk. It can be really interesting to see how different authors interpret the characters' emotions and motives.
The main characters are the Avengers. This includes Iron Man, Captain America, Thor, Hulk, Black Widow and Hawkeye. Ultron is also a major character as he is the main antagonist in the story.
One possibility could be that Naruto is somehow transported to the Avengers' world during the Age of Ultron. He might initially be seen as a threat due to his strange powers. But then he could prove his worth by using his ninja skills to fight Ultron's minions. His shadow clone jutsu, for example, could be very useful in confusing the robotic enemies.
I think Loki can be a really interesting character to focus on in Avengers sitcom fanfiction. He has that mischievous nature that can stir up all kinds of trouble in a sitcom environment. His illusions and tricks could be used for comical purposes, like making the other Avengers think there are hordes of tiny monsters attacking them. Scarlet Witch could also be great. Her powers are a bit unpredictable, and in a sitcom, this could lead to some really funny and unexpected events. Maybe she accidentally turns all the furniture in the compound into animals one day while trying to practice her powers.
Spiderman's presence could also change the outcome in terms of morale. His youthful energy and determination could inspire the other Avengers. In the face of Ultron's seemingly unstoppable army, Spiderman's never - give - up attitude could be the spark that keeps the Avengers fighting and ultimately leads to their victory.
If Flash joined the Avengers in the Age of Ultron, his super - speed could have been a great asset. He could quickly reach danger zones, evacuate civilians much faster than anyone else. Maybe he could even run circles around Ultron's minions, confusing them and buying time for the Avengers to strategize.
Definitely Coulson. He has such a rich backstory and his relationship with both the Agents of Shield and the Avengers (in an indirect way) is very interesting. His resurrection in Agents of Shield also provides a lot of potential for fanfiction. You could explore how he copes with being brought back to life and his new purpose.
