Nightmare X: If I had to describe this guy in one word it would most likely be "Hateful". NMX spends 28 hours a day hating everyone and everything, from Ronald McDonalds to Hippies to endtype to pretty much everyone else. Nightmare X also enjoys pissing other people off and getting as much hate as possible, why? I have no idea, but he claims he "enjoys making fun of his haters".
Nightmare X enjoys eating Doritos, annoying people, being overly mean for no good reason at all, bashing people belonging to "dumb stereotypes" and making fun of everyone who ever opposes him in an overly sarcastic way.
NMX also has an enormous grudge against the Italians, because "they want to steal his Dorito Stash".
Nightmare X is currently on TPH, typing a post about himself from a third-person perspective.
By the way, Nightmare X hates you, even if he has no idea who you are, he would probably punch you in the face if he met you in real life.
Lucifer/L/The Sum of All Fears/That Guy/TheSmash/L is ON FIRE!!/something else: Insane, simply insane, if I had to describe his insanity his description would be longer than mine and since I'm a fuggin egomaniac I'm not going to allow that.
KingSpider: Undercover agent dude, pretends to be nice to stupid losers lurking the internet and spies upon them gullible dumbasses, despite the fact he's as mean and badass as the rest of the Illuminati.
