History NightmareFuel / CodeLyoko

*** To make matters worse, Yumi did in fact die temporarily in the same season in the episode"Cruel Dilemma" where she fell into the Digital Sea in the climax where Ulrich arrived too late to save her. Had it not been for Aelita's kindness to offer up a chance of being materialized to Earth to bring Yumi back. '''Yumi would have died permanently in Lyoko!'''

** Speaking of Yumi, she got the closest any of the heroes had of being KilledOffForReal (next to Aelita who actually did die temporarily in the Season 2 finale), when XANA took control of the eponymous satellite in "Satellite" to fire on her, how close was she to being splatted by the laser? A ''millisecond'', had Jeremie and Aelita been a second late, Yumi would have been brutally murdered in front of everyone. [[note]]Making matters worse was that the blast radius would've incinerated Odd and the other kids that were around the area, meaning XANA would've killed a bunch of [[DeathOfaChild kids]].[[/note]]

** For the crows, much like in the infamous 1963 horror classic film ''Film/TheBirds'' they almost shred poor Yumi into pieces. Literally she was screaming while they were pecking her into a coma (in a not too similar scenario to the iconic phone booth scene) while she was hiding out in garden shed. If it hadn't been for Jim and Principal Delmas arriving at the right moment, Yumi would have been found dead in a horrible mash, and she was still barely alive on the way to the hospital, luckily she was saved with a Return to the Past.

* "Guided Missile": This episode provides one of the most horrifying XANA attacks of the entire series. Jeremie, who has a fear of flying, is trapped in a falling fighter plane about to hit the factory. Anyone who does not get heavy {{Fridge Horror}} vibes was probably born after 2001. The military proceeds to threaten the 'tango contingency', which means shooting down the plane. The pilot's attempt to eject fails, which is Nightmare Fuel in of itself, as that would mean XANA has accessed non-electronic technology in their seats. But what truly sells it are the only two options the military has: shoot down Jeremie and the pilot, or let the plane crash. This becomes horrifyingly familiar, [[RippedFromTheHeadlines considering suicide bombings in today's world]]. If it hadn't been for Aelita, this episode would have had a massive {{Downer Ending}}.

** One time XANA decides to store up electricity in a power transformer to sabotage a nearby nuclear power plant and thus, cause a meltdown! As soon as the Lyoko Warriors realize what's going on there is instant infighting as Yumi wants to tell everybody what's going on while Jeremie is suffering from a serious case of LoveMakesYouDumb and doesn't want to tell anyone to preserve Aelita. Considering how many lives could've been lost if XANA succeeded and considering what happened the few times there have been nuclear meltdowns, there are some serious cases of FridgeHorror there. Did we mention that this happened in the ''second episode''?

** XANA-William. Now under XANA's control, William has been upgraded into a dark and powerful [[TheJuggernaut juggernaut]] leading XANA's forces on Lyoko. His expressions are unsettling, and much like his master, he rarely ever talks, except to grunt and yell... until later, when he starts ''taunting'' his former allies and openly threatening them with his demonically warped voice. He's extremely brutal in battle, to the point of the show needing to use a GoryDiscretionShot at times, which it has NEVER needed with XANA's other monsters.

** The reason being that XANA was, and in fact, still is, unique among the majority villains in the realm of pop culture is that he never personally appeared or communicated with anyone throughout the entire series, with the exception of four/five episodes at most, out of ''97 total'', meaning the viewers were just in the dark about it as the characters, in fact, to this day, audiences re-watching the series have a hard time pinning down XANA's motives. XANA is literally the result of a villain who is NothingIsScarier as a character. If this isn't enough convince you how terrifying he is, just read the rest of this page to see how much it is related to XANA. It's made even more eerie considering that unlike most villains, XANA ''has'' no face nor voice: It (or "he" as referenced by the cast, [[Main/LostInTranslation due to French grammar]]) simply uses actions to "speak", which basically is '''kill all humans''' for [[ForTheEvulz no other reason other than sadism]].

* A lot of the crazed expressions XANAfied William makes.
** Not just him actually, ''any'' XANAfied person will often wear an unsettling expression with VoiceOfTheLegion to boot.
