Setting up the villain in a series is pivotal for the show's success, and some TV shows manage to introduce their antagonists spectacularly. While the show may revolve around its protagonist or hero, the villain is often equally important as they provide tension, drama, and challenges for the hero to overcome. Whether this villain is menacing, murderous, or overwhelmingly intimidating, their first appearance and introduction as the antagonist is vital for setting the tone of their character.
