History NightmareFuel / PowerRangersDinoCharge

* The Rangers' plan to save the Earth in ''End of Extinction'' backfires horribly, causing the planet to be pulled into a black hole. Even with the RetCon after they go into the past fixing things, they will still have to live with the knowledge of what happened in the original timeline.

* The Sabertooth Tiger at the beginning of "Return of a Caveman" (though the ConspicuousCG makes it more of a NightmareRetardant).

* ''Nightmare in Amber Beach'': despite the monster of the week's ridiculous design, his demeanor and the things he does involving his attacks on the Rangers is pretty scary.

** When Sledge shows up, it actually becomes clear that he was planning on [[spoiler: executing both her ''and'' Keeper, immediately]]. No [[BondVillainStupidity convoluted death traps]], no taking the time to try to interrogate either of them for information that he knows they would never give, just the immediate decision [[GenreSavvy to get them out of the equation, permanently]].

* The AdultFear moment in "Rise of a Ranger": Chase's little sister is in the middle of a firefight, being ''actively targeted'' by the bad guys, she's calling for her big brother, and Chase can't reach her.

* An in-universe one for Koda when Iceage almost freezes him in "When Evil Stirs", it triggers memories from when he was frozen 100,000 years ago and Koda understandably panics.

* ''Gone Fishin' '' features Riley's brother caught up in the machinations of Heckyl. Stuck below the surface of the water, slowly suffocating to death. It's just like in True Black, only here, it's even worse, because they don't even know where in the lake he is.

** Conductro and Screech themselves could also add to the creepiness. While many of the other monsters are more colorful and silly looking in appearance, Conductro and Screech appear to be nothing more than humanoids in plain black and white suits and hoods, with each wearing a plain white mask, Screech's being an overbearing smile, and Conductro's being an agonizing and sorrowful frown.

* Conductro and Screech's plan to use music to turn the entirety of Amber Beach into zombies, the music instantly causing anyone who hears their music to not only fall under their spell, but also become pale with dark circles around their glassy eyes.

** Alsongside this, the ominous and disjointed music that Screech plays with his trumpet doesn't make it any better.

** And it has the power to bring out a person's dark side and give it form, as shown with the creation of Doomwing from Zenowing or completely corrupt a person, like it did with [[spoiler: Heckyl]].

* The backstory to the Dark Energem. The EvilCounterpart to the energems, it was hidden away on a planet called Sentai 6...only for an alien warlord to blow up the whole planet just to get his hands on it. Nasty.

* ''Gone Fishin' '' features Riley's brother caught up in the machinations of Heckyl. Stuck below the surface of the water, slowly suffocating to death. It's just like in True Black, only here, it's even worse, because they don't even know where in the lake he is.

* [[spoiler:The monster locked up in solitary confinement. It's not even fully contained in there as it's tentacles are able to slip out and attack anything.]] If you're a Kyoryuger fan, you know exactly who is locked up in there.

** Hell, Heckyl's behavior throughout the episode is akin to a stalker or killer.

** The confrontation between Heckyl and Shelby, which is tense simply because there's no telling what someone as psychotic as Heckyl would do in that situation.

* Within ''hours'' of taking charge, [[spoiler: Heckyl/Snide]] is able to [[spoiler: capture five Rangers and, seemingly, line them up to be ''executed'']].

* An in-universe one for Koda when Iceage almost freezes him in "When Evil Stirs", it triggers memories from when he was frozen 100,000 years ago and Koda understandably panics.

* Albert Smith. He has bonded with the Purple Energem, stopped purse robbers, saved cats, and arrested thieves. The way he constantly freezes up in front of Monsters, wanting to ''kill him for the Energem'' serves as what can happen when [[NothingIsScarier an inexperienced Ranger goes up against a monster willing to kill them without hesitation]].
* Wrench was perfectly willing to [[spoiler: toss Kendall into the incenrator.]]

* Greenzilla. Not only is it hideous, it comes off as a nonsapient beast with little more intelligence than 'maul whatever is in front of me'. It basically spends most of it's battle with the Dino Charge megazord ''literally'' mauling it, with even their {{Finishing Move}}s not so much as scratching it.

* An in-universe one for Koda when Iceage almost freezes him in ''When Evil Stirs'', it triggers memories from when he was frozen 100,000 years ago and Koda understandably panics.

* The last few moments of "One More Energem": [[spoiler: Sledge's ship is crashed, but someone is still alive on the ship, ready for his chance of power--It's Heckyl/Snide.]]

* The last few moments of "One More Energem": [[spoiler: Sledge's ship is crashed, but some''thing'' is still alive there and is pretty eager to get in on the action now that it's free]].
