Example: The villains who are powerful, but aren't the most powerful would have code names like Rome, Ankara, Vienna, and Canberra. Is this a good idea or not?
Does anyone have advice on how to make characters that aren't needed to push the story forward but are still likable?
Edit: This is off-topic, but I don't want to create a thread that could be unnecessary. Is it a good idea to have the MC turn out to be working for the opposite side?
