What to wear: We have a feeling Negan will be a popular costume this year, and for good reason. Slick your hair back, glue on a mustache, and then put on a black leather jacket, a red scarf, dark pants, and a leather glove on one hand, and carry around a baseball bat covered in barbed wire.
How to act: Negan treats everything he does as if he's centre stage, in the midst of a performance. He's simultaneously charismatic and terrifying.
