Supernatural: Every Major Villain Ranked Worst To Best
9. Abaddon
Abaddon was one of the last remaining demons that genuinely presented some kind of threat to the Winchester brothers.
Originally thought to have been killed, she travelled through time and began wreaking havoc in what was then the modern-day. Her tenacity and vicious love for killing was only matched by her dark sense of humour. Even when up against Dean and co. she enjoyed their seemingly futile attempts at fighting her.
Abaddon has been shot, stabbed, and decapitated but still managed to bounce back proving she was worthy of the Knight of Hell title. Her cocky demeanour and quite frankly total disregard for caution ended with Dean finally piercing her with the First Blade while branded with the Mark of Cain.
It was a fun experience to watch a demon genuinely enjoy their work, however sadistic it was.
