You write speculative fiction for the same reason you’ve read or watched it your entire life. There’s something inside of you that craves tales of relatable characters overcoming adversity. It’s your inner hero, and it manifests on that illuminated screen when you sit alone, clicking away on the keyboard. That something becomes the characters that you put your heart and soul into, hoping to all things sacred that your readers will love them–because after all, they’re a part of you.
But what about the bad guy? Every element in good storytelling exists for one of two reasons: it either builds tension (conflict) or releases it (resolution). Genre fiction often utilizes an antagonist to build its tension. Since horror thrives on developing this character, authors of other speculative genres can learn a lot from horror writers about creating good villains. There are many ways to craft a good bad guy, but this horror author has found that they essentially boil down to three “R”s.
1) MAKE YOUR ANTAGONIST REAL.
Whether your bad guy is a malevolent mastermind from another realm, a big, dumb troll, or a serial killer, your task as a writer is to make me believe he is real within the world you’ve created. After all, how could something phony pose any real threat? If it’s sentient, consider adding a humanistic quality: Jealousy. Genuine anger. A moment of empathy. Maybe even a brief second-guessing of the morality of his actions. Anything with which your audience can relate, and therefore, believe. Unless this character is invisible, be diligent in your physical description of him. This may seem like a no-brainer, but you would be surprised how many authors over-describe their heroes, yet under-describe their bad guys. Think of your story in terms of visual-media, and give your antagonist some close-ups. Tell me about his rancid breath as he leans in to place cold, steel chains on your heroine’s wrists. How do the warm drops of sweat feel as they roll off his bald head to land on her face? Are the threads that stick out from the bottom of his robe frizzed? You don’t have to describe every crack in his pinky-nail, but a few cleverly placed details will give him flesh.
2) MAKE YOUR ANTAGONIST REALLY MENACING.
Not just menacing to the world at large, either. This malevolent force should be particularly menacing to your hero or heroine. A manifestation of their fears and past failures. His very existence should threaten something dear, even if it’s only their sanity. Reveal just how terrible he is in increments, as the story unfolds, through acts of treachery. Deviate from your outline, and use him to kill a character you never intended to kill (if it hurts you, it will hurt your readers.) Progressively change the tone of your writing to reflect your hero’s growing distress with each revelation. This will cause the audience to sympathize with them, putting them in your hero’s shoes, and increasing the satisfaction of their ultimate triumph (or in the case of many horror stories, the impact of their failure).
