Fictional characters that would have made movies more badass if they had a bigger role. These characters should have been featured more in a movie or have their own movie. You can add on to this list. Some of these characters were real, and the actors were portraying real people. I don't consider their interpretation to be real and to me it is a fictional character that can be in a badass spinoff movie.
