I'm inspired by Draco Malfoy from the Harry Potter series! When I was younger, he was always my favorite character- I guess I just have a thing for snobbish, intellectual boys? He ended up reforming at the end, and I thought that was very noble of him. I liked how his character arc turned him from a whining, self-centered asshole into a developed person with thoughts and motivations.
I also take a lot of inspiration from Light Yagami, the main character of Death Note. I guess inspiration isn't a very good word... but he's diligent, and works to create a better world in the beginning, though his ego is his downfall. Light is clearly the villain, saying he's driven by a better world in the end, when, in actuality, his motivation is his ego and lust for power, but he got results.
Clearly, cold boys in fictional series capture my attention better than everyone else. ^^;
