Nightmare Fuel / Denji Sentai Megaranger

• Practically everything about Nezirejia in general. Some Nezire Beasts are disturbing in appearance even compared to Sentai standards, and some of them are terrifying just due to what they do.

• Episode 4 introduces Chamelon Nezire, who Shibolena uses to turn internet users into psychopaths and dark their dark inhibitions, special note being Ms. Nishiyama who murdered small animals before attempting to kill Koichirou. It becomes Harsher in Hindsight when people are manipulated via the internet into doing terrible things without Nezirejia's help.
• Episode 14 has the Kunekune taking on the appearance of citizens, their leader Boss Kunekune posing as a police officer. It could be seen as similar to Invasion of the Body Snatchers (1956) in concept.
• Guirail counts: his debut episode, where he arranged children to be used as human shields with Kenta nearly quitting after accidentally hospitalized a kid the villain placed in the way of his punch. The following episode, he modifies Crocodile Nejire via cloning technology with the process bordering Body Horror.
• Coral Nezire is horrifying. His appearance is like that of a coral-like Monster Clown, and his special ability is spitting foam all over his victims, which causes them to slowly transform into coral. Episode 27 is full of his terrifying plan to transform as many people he can by dragging them into the ocean and infecting them with his poisonous foam, resulting in their slow and painful transformation.
• What becomes of Guirail... well, we can't say he didn't deserve it, but it is pretty terrifying as to what happens when he eats the Nezire Source Capsule. After kicking around the Megarangers for a good long — and blasting Shougo because he was there — suddenly, Guirail starts to let off bursts of sparks, and he starts to tremble as a viscuous ooze starts to leak from his body. Guirail retreats while covered in this slimy, disgusting fluid, all the while in immense pain. And then he's confronted by Dr. Hinelar and Shibolena, who explain the consequences of the Nezire Source Capsule. Turns out, it's an unstable pill guaranteed to cause hideous mutations while transforming the consumer into a mindless, twisted giant. And just that happens to Guirail, as he grows into a titanic, horrifying monstrosity that proceeds to wreak havoc all across Tokyo. It's pretty obvious that when the Megarangers come across this monstrous new form of him, it seems as though he's in a constant state of immense pain, roaring and screaming and lashing out at everything he sees. But then he becomes The Juggernaut, in that despite being robbed of his personality and mind, he is still incredibly powerful thanks to the Nezire Source Capsule increasing his strength exponentially. The Super Galaxy Mega is left powerless in his wake. Oh, and he spawns a monster after getting hit by the machine's brand-new finisher, which hardly fazes him aside from knocking him down. The Megarangers almost don't defeat him and were it not for the Space Mega Project being complete, the abomination of Nezirejian science that was Mad Guirail would've meant the end of Earth.
• Episode 38 has the newly introduced Nezirangers memorizing the sound of the Megarangers' Digitizer, which potentially allows them to seek out the Megarangers before they can henshin. This leads to a horrific montage of them assualting random civilians who own a popular minicomputer. Why? The device makes the same sound as the Digitizer. Cue Nezi Black throwing one of the Megarangers' friends from school into a bench, and two girls being given a Neck Lift by Nezi Pink, who strangles them into unconsciousness. Nezi Black eventually catches on when he notices the device... not that it stops them from assaulting more people.
• Javious' death in Episode 43 especially counts — when the Nezirangers have finally managed to drain all of his power, he screams Hinelar's name as his eyeball bursts out of his monitor, in CGI, and gets way too close to the camera before it explodes into a billion pieces. Brrr.
• In episode 48, Hinelar pulls the mother of all Near Villain Victories when he lures the Megaranger to a trap where he's converting humans into data cards, easily tricking Pink and Red into falling straight into the path of his machine, with Pink sacrificing herself to save Red, who can only helplessly watch as she screams to be saved before she is reduced to a mere data card. Hinelar proceeds to explain his intend of altering everyone's data to make them [Cult of Personality committed to him and his vision.]], informing Mega Red that his machine is the only thing that can restore Pink as she pleas him to destroy it regardless of becomes of her. Hinelar mocks Mega Red putting his heart first as the other Megarangers enter and digitizes them all quickly, essentially ensuring Hinelar's victory there and then. It's only thanks to the Nezirangers' interference that Hinelar does not have the chance to turn the Megarangers into his followers.
