History NightmareFuel / SamuraiJack

*** Now, think back to “The Aku Infection”. Jack swallowed only a small portion of Aku, and it slowly mutated him into an Aku clone. The High Priestess drank ''way more'' than that, and it didn’t mutate her like Jack. That’s only a testament to not only how psychotically devoted she was, but how she was ''already'' so corrupt that even Aku’s evil essence can’t corrupt her any further. She likely thought she could get a portion of his powers for herself.

'''Jack:''' ''(completely possessed by Aku except for a bit of his face left) ''I seek to foil the samurai! To destroy his dream of going '''home!''' And to destroy all who stand in my way!''''

-->'''Jack:''' "I'm getting..."

-->"Come... ''Come...!''"

-->''"Once again, I am free to smite the world as I did in days long past."''

* It gets downright hectic and overall a bit eerie, since you have two of the deadliest warriors hunting one another in the art of ninjutsu. All the while, they're both clad for the appropriate elements. One fights in the shadows, while the other fights in pure blinding light. The whole fight in the very wooden tower is both a respectful mix of NightmareFuel and ParanoiaFuel. And to add even more fuel to an already deadly, adrenaline-rushing encounter? The soundtrack throughout the whole fight! ... Horror chords and all. [[https://www.youtube.com/watch?v=bmkxsQnNujI Here is the fight in its entirety]].

* TheReveal that '''''JACK LOST HIS SWORD'''''. Yes, that's right; '''''[[PunctuatedForEmphasis JACK. LOST. HIS. SWORD,]]''''' the ''only'' weapon on Earth that can harm Aku. And while he's managed to keep that fact hidden so far, it's only a matter of time before Aku himself finds out about it. Good luck, Jack. ''You'll need it.''

* The Mechanical Beast is absolutely frightening to behold. First, it sneaks up on Jack and the king of the Spartans out of a pipe, its malicious red eyes lighting up in the dark and glowering down at them. Then out comes a giant ball with huge fangs and toothy tentacles that makes the [[WesternAnimation/TheIncredibles Omnidroid]] look like a dust bunny. And all the gravelly [[HellIsThatNoise SCREECHING]] it does when it's angry or injured is like hearing the bloodlust of an angry vampire bat!!

* Think of how powerful Aku is. Now mull over the fact that as horrifically mighty as Aku is, he is nothing but a tiny, tiny fragment of an infinitely more powerful EldritchAbomination that took the heads of three pantheons working together to kill... and even then they failed to finish the job. It's a bona fide CosmicHorrorStory, [[WhatDoYouMeanItsForKids in a cartoon for kids]].

** In each of the visions Jack sees... ''someone'' on horseback. We're never told or fully shown who it is... but whoever it is? It's something that '''terrifies''' Jack. ''Yes, Jack is '''terrified''' of something''.

*** Bit of a meta-example: [[ShoutOut the dog's name is]] '''[[{{Manga/Parasyte}} Shinichi]]'''. Considering the fact that Aku was little more than a parasitic life-form growing bigger and stronger from devouring other life-forms at this point in time, and the fact that the ''Parasyte'' manga features a dog overtaken by a parasite eating another dog, creates a creepy crisscrossing reminder of each work's NightmareFuel.

* In the online game "Desert Quest", Aku and his minions attack a village and injure many people, [[WouldHurtAChild including a little girl]] who is on the verge of death unless Jack can retrieve a sacred crystal that can be used to heal her.

* When Jack and Ashi are visiting a BazaarOfTheBizarre, Jack eats a weird and still-living [[AlienLunch worm creature]] which he thinks tastes delicious... but then his face suddenly turns into a ''colorful fish''. It creeps out Ashi so much she decides not to eat it. Even though the effect is temporary and PlayedForLaughs, it's still a little bit freaky.
