Michael Myers


 * Psychotic: Literally all Michael Myers does is kill and stalk people he plans on killing.
 * Emotionless: Myers barely even qualifies as a human, moreso a personification of evil itself. Emotion is irrelevant, he never speaks, and his mask is specifically designed to be as inhuman and hollow as possible to embody who he is perfectly.
 * Determined: Evil is unstoppable, which means Michael is.
 * Sociopathic: Painfully murdering innocent teenagers for absolutely no reason is his full-time job.
