At NYCC, Lone Wolf & Cub creator Kazuo Koike offered a pro-tip for writers and aspiring writers who struggle to write their stories:
Create the villain first.
For Koike, once a writer has a well-defined villain with motives and the antagonism he or she might wreck, it gives something for the heroes to fight against. The villain's actions come to define the hero.
Citing the CW TV series Supernatural as an example, Koike talked about how the heroes Sam and Dean were likeable, slightly hapless guys who don't know what to do when the villain of the week attacks, and have to work out how to fight and win each week. That is how the audience comes to know the heroes.
Creating a good villain for this reason is a practice commonly preached by the likes of screenwriing guru Robert McKee, other writing teachers, and the best screenwriters in Hollywood and beyond.
Perhaps the most pleasantly surprising revelation here is that Koike-sensei likes to watch Supernatural.
