"Firstly, the character has to, in one way or another, be funny," says Shea Serrano. "...Secondly, the character has to seem like they would be a chore to hang out with but also like it might be the most fun imaginable...Thirdly, the character has to make you ask yourself some questions that maybe you’re not so interested in answering...Fourthly, and this is a silly one but also a very important one, but the character has to have a cool name....Fifthly—and this is the inverse of the funny thing from earlier—the character has to be able to access a level of emotional warfare that you weren’t expecting...Sixthly, the character has to be able to be completely comfortable no matter who they’re sharing a scene with...Seventhly, and lastly, and the most vaguely, the character has to have that indescribable quality that makes you feel excited whenever they pop up on screen."
