I would cast Tom Hiddleston as the main villain. He has already played Loki in the MCU and has proven his ability to be a complex and engaging villain. His charm and acting skills could bring a new level of menace to an Avengers fanfiction.
No, it wasn't. There was no mention that Natasha was the main character in The Avengers. The main character of My Marvel Superman Girlfriend, Xinian, had superpowers. In addition, Natasha in My Sister is a Black Widow also appeared in the Avengers, but there was no mention that she was also a superhero.
It could be Mysterio. He's a master of illusions. He might trick the Avengers into believing that Spiderman is a danger, using his illusions to make it seem like Spiderman is doing bad things. So the Avengers, thinking they're doing the right thing, kidnap Spiderman.
Loki could be a likely villain. He has a history of mind - controlling people and causing chaos within the Avengers. He might see Hawkeye as a useful tool to disrupt the team again. His mischievous nature and magic powers would make it easy for him to brainwash Hawkeye without being detected at first.
Scum Villain Self-Saving System was a novel in which the male protagonist was a man with a complicated background and different goals. The story was about how he became a villain for some reason, but after constant struggle and self-reflection, he gradually cleared himself and finally became a positive character. The novel was a fantasy novel with ups and downs in the plot and vivid characters, which was very popular among readers.
The so-called Scum Rebel was an anime whose name came from the novel," Scum Villain Self-Rescue System." The main story of the work was about a male protagonist named 'what'. He was a controversial character with many identities and goals, but he was often in trouble. In the anime, the characters were vivid, the plot was compact, and the beautiful pictures and music were deeply loved by the audience.
An extremely down-to-earth anime referred to a very realistic work that was close to life. The storyline and characters were very practical and close to reality, and could resonate with the audience. The story was about an ordinary person named Xiao Tian. He worked hard to realize his dream, but at the same time, many stories about family, friendship and love happened. It was very touching.
In some fanfictions, Tony might be kicked out of the Avengers because of a conflict in leadership styles. Maybe his high - tech and sometimes risky solutions don't sit well with other members who prefer more traditional or cautious approaches. For example, if a mission goes wrong due to one of his untested inventions, the team could lose faith in his decision - making abilities.
I recommend " Dressed as an Ancient Glamorous Man, Coaxing the Big Villain Every Day " and " Villain and Blondie." Both novels had plots where the female lead turned into a villain or a bad woman, and both had magic elements. The former was about the protagonist transmigrating into a Mary Sue novel and becoming a dark, ugly, and fat villain, and successfully counterattacking through the system, while the latter was about the protagonist transmigrating into a primitive fantasy world and becoming a yellow-haired villain, getting along with all kinds of strange characters and taking risks. I hope you like my recommendation.😗
One great Avengers fanfiction to watch next could be 'The New Avenger'. It has an interesting plot where a new hero emerges and has to prove themselves to the established Avengers. The character development is really well - done.
