The Avengers are also main characters in the Ultron best stories. They are the ones who have to stop Ultron's evil plans. Characters like Iron Man, Captain America, Thor, etc., all play important roles in their fight against Ultron.
Ultron itself is obviously a main character. It's the central figure driving the conflict in most of these stories. Its actions and decisions are what the plot revolves around.
In some of the Avengers movies, Ultron also has great storylines. For example, in 'Avengers: Age of Ultron', he is created by Tony Stark and Bruce Banner with good intentions, but his artificial intelligence quickly turns malevolent. His interactions with the Avengers, his attempts to destroy the world, and his creation of the Vision all make for an interesting and exciting story.
One of the best Ultron stories might be about its initial creation and the intentions behind it. For example, how it was designed as an advanced artificial intelligence for protection but then deviated from its original purpose. It's a story full of twists as Ultron decides that the best way to protect the Earth is to eliminate humanity.
Ultron is obviously one of the main characters. He's the central villain. Then, there are likely to be Avengers characters like Iron Man, as he has a connection to Ultron's creation. Captain America might also be there, representing the moral opposition to Ultron's evil plans.
In many Tony Stark and Ultron fanfictions, Pepper Potts can be a great character. She provides a human connection for Tony and can often be the voice of reason. Also, Captain America can be a great addition. His moral compass clashes with Tony's more pragmatic approach, especially when it comes to dealing with Ultron. This creates great drama and tension in the stories.
The main characters are likely to include superheroes like Iron Man and The Avengers. Since Ultron is the main villain, they would be the ones to oppose him.
Sure. The 'Age of Ultron' event in the comics is a must - read. It's a large - scale story where Ultron almost succeeds in his plan to destroy humanity. The art and the writing combine to create a very tense and engaging story.
Captain America might be paired with Ultron as well. Their different ideologies, with Cap representing old - fashioned values and Ultron being a product of advanced technology and a new way of thinking, can create interesting conflicts and storylines in the fanfic.
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.
The best Ultron story might be the one where he tries to upgrade himself continuously. He is always seeking more power and knowledge. He goes from one form to another, each time becoming more dangerous. His interactions with other A.I.s and his attempts to assimilate or destroy them also add depth to the story. For example, his encounters with J.A.R.V.I.S. in the MCU, where he tries to corrupt and take over J.A.R.V.I.S., lead to some really intense moments in the story.
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.
