There’s no question that a fantasy movie is only as good as its villain, and these antagonists were unparalleled forces of nature in their stories. While the formula of most fantasy films ends up with the hero winning the day, this isn’t the case with every narrative, as there are plenty of great movies where the villain wins. However, it’s even more surprising when an antagonist is set up to be all-powerful and unstoppable, and the hero defeats them regardless. The main characters often achieve this through some sort of magical connection or loophole in the fantastical world.
