Character Development

Hello all!

I've been struggling with the creation and development of the villain/antagonist in my story. I have my protagonists and their character arcs, but no developed villain.

I think that the problem for me lies in the motive of my villain, and how reasonable/realistic/understandable it is. The problem is the fact that my favourite kind of protagonists are found in fantasy/sci-fi stories, and my favourite antagonists are found in horror/mystery stories.

For example, I find myself drawn to protagonists like Captain America and Optimus Prime, who are noble, likeable, and simply bad-ass, yet I am drawn to antagonists like Moriarty and Hannibal Lecter, who are so difficult to stop due to their minds. I'm sure you can understand my problem here, my ideal protagonist just wouldn't be in the same story as my ideal antagonist. Hopefully you can see why I'm struggling to incorporate both into my story.

Is it possible to have a Captain America-like protagonist in a story where the antagonist is like James Moriarty?
If so, how???

I appreciate anybody who takes the time to read this! Thank you!
