Some characters and story ideas wouldn't work for the first Avengers movie, What characters do you think should be in the sequel? Who should be the bad guy, what story should they do? I have an idea for the sequel that wouldn't work really for the first Avengers movie. Avengers 1) Introduce all the characters, get to know them and their abilities, and personalities. I think Loki/ Hulk team up would be good, with Hulk being manipulated by Loki against the Avengers until Loki fights the Avengers himself. Avengers 2, or 3) Ultron was the bad guy. While the other films hint at Hank Pym's instability, this film really shows it. We see how insecure he is, how mentally unstable he is, and how he resents his fellow Avengers, and himself. He even has a break down earlier, perhaps. He feels he is a failure as a scientist, avenger, and husband. He might not be, but he thinks he is. He builds Ultron, and AI robot. Ultron hates all life on Earth and wants to destroy it, but most of all he hates the Avengers. Especially Hank Pym. Ultron would be a living embodiment of Pym's dark side. While this film would have ultron as the villain, and focus on him, the main focus of the Avengers movie could be Hank Pym. Ultron, in his plans for destroying the Avengers and all human life, creates robot drones. His greatest weapon is the Vision. Vision, perhaps near the end of the movie, turns on Ultron very similar to how Ultron turned on Pym. Its not really plotted out, just some ideas of mine on how a Ultron Avengers movie could go. I also think that after Avengers 3 they could start with the rotating cast, maybe introduce some characters in Avengers 2 or 3 that would stick around as main cast members in Avengers 4, like Scarlet Witch, Hawkeye, Quicksilver, Vision, Tigra, Falcon, She-Hulk, Hercules, any character who would fit with the stories. Anyone else have any ideas on Avengers sequals, the characters, stories, coarse the movies would take?
