I just started writing a sci-fi/action/romance novel that was going to be about two people stuck in the middle of a war between humans and robots. The original idea was that machines would be getting so smart that they would become smarter than us, and they would be threatening to become the dominant species on the planet. I have been thinking hard about how it would work, and I didn't think it would be a very good idea (the reasons behind that decision are way too complicated for me to write down), so I decided to change my idea of an antagonist to something else. (If you want to see the original post on my story, go here: https://www.writingforums.org/threads/how-do-i-write-about-multi-day-events-such-as-going-to-school-every-day.131386/ ) I started to write the first ten pages or so of my story, and I mentioned a bully who pushed everybody out of his way on the transit system. I decided that I should focus on this bully as the main antagonist, since he used to be the boyfriend of the girl that the main character is involved with. (For the discussion on the main characters' relationship, go here: https://www.writingforums.org/threads/any-good-ideas-for-how-i-should-portray-romance-in-my-story.132331/ ) He is really good with science and engineering, so he's probably going to use his inventions to chase down the main characters either to get his girlfriend back or to try to kill them in anger and revenge. Exactly what's going to happen in the climax when he unleashes his ultimate creation, I'm not sure. I don't know if you guys have any DIFFERENT ideas or if you might be able to provide constructive criticism, but if you do, I would appreciate it!!
