To clarify, Paranoia removes your vision of friendly champions. This is usually followed up by Nocturne flying across the map to murder someone, and you won't know who until he latches onto his target.
And to make matters worse, it is implied that it is a spell that affects the summoners themselves, making them untrustfull towards eachother for a short moment. And if that wasn't bad enough, it is revealed in the "A Twist of Fate"-cinematic that the champions affected by it also get to see some rather damn creepy stuff similar to that of Dante's Inferno.
Gangplank's laugh when he fires his ult.
Fiddlesticks. Fucking Fiddlesticks. His Ult. is perhaps the scariest as well as the most dangerous. Made worse is that a good Fiddlesticks player WILL do it when everyone least expects it.
The huge-ass Shark that Fizz summons is quite scary the first time. Doesn't help that it's a huge Game Breaker.
If the shark finishes off a small champion, it eats them , as in, it takes the whole body and doesn't leave behind a corpse.
That moment in midair after a Singed fling/Blitz grab as you travel towards the enemy team.
Skarner's ult is the worst with it- before the bug was fixed, teleport used to be considered a debuff. So Skarners would hide in the bush, ult you, use teleport, then hit cleanse to reach their base instantly, taking you for the ride.
Cho'Gath's feast ability. He EATS YOU.ALIVE.
Cho'gath claims to have far worse things in store for you than merely eating you.
DEATH, is NOT the end for you. I have seen to it. For eternity; YOU. ARE. MINE.
Any character that turns invisible is this and Paranoia Fuel. Especially the Joker Expy Shaco with his boxes, and Twitch with his creepy laugh and devastating ult.
Twitch: Uehahauahahuaeuh!
Announcer: Pentakill!
Being taunted by Galio, Rammus, and Shen when you least want it.
When you're losing a match and your jungle is unwarded, suddenly the entire map is a very large, empty place, with the entire enemy team hidden just ahead in the fog of war. In every direction.
Warwick, especially when he smells you when your health is low. Just when you think your safe.....SURPRESSION!
Any time there's a skilled Rengar on the opposing team. That bush you're running by? He could be in there, waiting to pounce and take your head for his collection. Similar case with Kha'Zix except he doesn't even need a bush - and he'll likely leave less than a head behind.
Cassiopeia's ultimate ability, which petrifies nearby enemies that are her facing her, and to top it off it's accompanied by an almost demonic shrieking sound.
Zac. Oh, sure, he's a nice, friendly blob monster who is actually one of the straight-up good guys among the champion roster. He's also capable of coming from literally anywhere when he initiates ganks. With careful movement, he can avoid the common ward spots on the map, thereby likely bypassing your vision, and then come flying at you from odd angles. While he's far from the only champ with a wall bypass, nobody can bypass walls with the same distance and frequency as Zac. The entire game, you're left wondering if, when, and from where he's going to come at you.
Lores
Warwick was originally a deranged Mad Scientist prior to his transformation. The fact that someone only became worse when they had been cursed is really saying something. Just how horrible was he prior to his transformation?
Judging by what we saw in Karma's League Judgment, he was an absolutely disgusting bastard who made Singed look like a saint. Singed is merely callous and uncaring; Warwick went out of his way to be as horrible as he could out of sheer sadistic joy in the carnage he was causing.
With the new lore for Warwick, he's even worse. He befriended Soraka, then hired some guys to attack him so that she'd defend him, losing her divine powers in the process. Why? So he could eat her heart.
Singed, Warwick's student. Remember what happened in Riven's backstory? During a war with the Noxians and Ionians, Singed fired off salvos of an extremely powerful chemical weapon with no regard for who he hit, leaving the poor girl shattered mentally at the scene.
Turns out Master Yi was also a victim to this asshole. His village, attacked by Noxians, was brought down to ashes by Singed. Yi isolated himself to ensure that, as the last of the Wuju style, would not die out.
It can be said this champion is responsible for a lot of champions' fucked up lore.
He may have been a source of humorous memes, but Dr.Mundo may have actually been worse than Warwick. He started his sadistic experiments as a child, and only got worse and worse.
Here's some Fridge Horror: What the hell happens to his victims? Did they just die horribly? Or did he do even worse things? His Parents went missing by the time he was a teenager.
Urgot's fate. You're basically Immortal while being horrendously disfigured. He even laments that it sucks in his current position.
And what comes with his disfigured body? Eternal pain. Literal eternal pain. The only thing keeping him going is his near-endless hatred for Demacia, especially Garen. Come to think of it, pretty much every single thing about Urgot is terrifying.
Renekton. He had been around evil people for too long, destroying his mind and making him go crazy.
Orianna:[after reliving her implanted memories of the death of the original Orianna Reveck] Yes, I died.
Summoner Carin: We have entered your mind, Orianna. How did this make you feel?
Orianna:[creepy mechanical giggle] It was fun. I like memories. Don't you?
Fiddlesticks is bad enough in-game. His lore makes him much worse. He had to be sealed into the summoning chamber because they couldn't get rid of him. Everyone who went in was either cut down or driven mad.
Even worse, all anyone knows about his orgins is that a summoner attempted an extra-planar summoning. No one knows what happened or where the summoner went; all that's left of the event is Fiddlesticks.
Also [citation needs to be found] in the forums many people had asked for more information about Fiddlesticks his designer said 2 words, "He waits."
Some champions have to go to extreme lengths, if not divinely blessed, to get their magical powers. Syndra was some ordinary farm girl who was born with enough power to wipe out her village, and managed to raise a huge floating castle with sheer magical willpower alone.
Mordekaiser has been given new lore that paints him in a more horrifying light. A being of pure agony and suffering that predates the Shadow Isles, Mordekaiser is a master of using pain as a weapon and is on a horrifying quest across the land. A story from a young mage in training describes him interrogating her teacher. He said he would die before talking. Mordekaiser promptly kills him and tears out his soul to get the information.
Elise, the Spider Queen. Outside of being a horrifying Spider Creature, her lore is pretty nightmarish. As the leader of a cult worshipping a Spider God, she will occasionally take a pilgrimage of her followers to the Shadow Isles to find a shrine to their god. Once there... She lures them into a cave where a gigantic, undead spider lays in wait, which eats all the followers and gives Elise venom that staves off mortality a little bit longer. The kicker? Elise does this every few weeks.
Evelynn is a total mystery, and the only thing people can gather from her is that she likes to kill. And is very good at it. What makes this very scary is that nobody knows the real reason for why she is in the league, but whatever the reason may be, it's big and she will probably effect everyone with it.
Though if she and Twisted Fate could get along, maybe she's not the worst thing to step into the League.
It gets better. Almost all of them have specific dialogue for when they capture the West or East Altar. The spirits of the East altar beckon them to let loose their powers, and the spirits of the west either hold them in contempt or tries to reason with their better nature. The spirit of the West Altar also implies that Mordekaiser is actively using Hecarim to his own ends.
Hecarim's lore is bad enough by itself. He's an undead centaur who commands an army of ghosts, and he's only a demonstration of the Shadow Isles' military strength. His battles before he entered the League left everyone that stood against him insane or dead. And the Altars hint that he may have once been a knightwho was killed by Mordekaiser, with his soul trapped in his haunted armour.
Cling, clang, go the chains Someone's out to find you Cling, clang, oh the chains The Warden's right behind you Quick now, the seeking chains Approach with their shrill scrape Don't stop, flee the chains Your last chance to escape Drag the chains, drag the chains With all the strength you may Drag the chains, drag the chains Or they'll drag you away Cling, clang, go the chains There's no more time for fear Cling, clang, oh the chains The last sound that you'llhear.
It doesn't(?) help that he was horrifying both in life and after, as Thresh. In life he was a sadistic jailer. After death, he only got worse - now he tortures you and then imprisons you in his lantern to be taken to a forsaken ghost-hell-island.
