Fallen/YMMV


 * Complete Monster: Azazel, considering his M.O. is to completely ruin people's lives and then kill them.
 * Fridge Horror:
 * This happens anyway, since he possesses a nearby guard instead.
 * Paranoia Fuel: Azazel lives and breathes this trope. He can freely possess anyone who doesn't have strong enough willpower to resist him with a touch. In a crowded area he can be anywhere in moments. And if you kill one of his hosts he can just possess anyone he likes. He turns normal people into serial killers and does it purely For the Evulz. And it could easily be you next.
 * The Woobie: Plenty of Azazel's hosts qualify, Charles being a very notable example.
