History NightmareFuel / JonnyQuestTheRealAdventures

* The aquatic monsters accidentally unleashed in "Undersea Urgency" are unrelenting killing machines who claw apart and devour dozens of characters onscreen. When it looks like one has been killed, the head scientist of the undersea base wishes to take the corpse with her so they can learn more about its species... and then the creature awakens in her arms. It immediately cuts back to Dr. Quest and Jonny, who can only cringe in horror as the scientist is ripped apart.

** To make it worse, at the end of the episode, the monsters are still free, and our heroes don't do anything to try to stop or contain them.

* "Race Against Danger" had Clark and Hill killed in extremely disturbing fashion by having Hill thrown into a pit and Clark ripped apart by mechanical branches. It is later revealed, in the surveillance video Race and Jonny are forced to watch, that Hill is not just thrown into just a simple pit, but a SPIKED PIT.

* "More Than Zero" was an episode about two paranormal specialists investigating a haunted house in Venice, and Dr. Quest arrives with Race, Jonny, and Hadji to lend a hand. Needless to say, the house is more haunted than ''any'' of them would've expected.

* The villain of "Nuclear Netherworld" falls into his own radioactive waste. The result is [[RealityEnsues he suffers from severe burns and radiation poisoning]], and he dies very soon.
* "Ndovu's Last Journey" sees the EvilPoacher villain light a fire to around Jonny, Jessie, Hadji, and a border patrol in an attempt to kill them all. One of the unlucky patrolmen actually catches on fire.

* Also in Race Against Danger, [[spoiler: Greg Temple who had been impersonating Kreed, meets with a kharmic end when one of the machines death traps malfunctions on him and kills him. Could Greg Temple possibly survive being shot several times??? Maybe, but not the islands self destruct mechanism which has now been reactivated upon him dropping the controller for it. Bonus points for if he was not quite dead yet from the gunshots but still aware of the countdown to the explosion, whilst being too weak or injured to crawl to the remote to stop it.]]
* The hunter getting mauled by a tiger in the episode "Manhattan Maneater". Seeing nothing but the tiger's claws only adds to the terror.
* The greedy developer [[spoiler: eaten alive by alligators in "Alligators and Okeechobee Vikings". Though it's offscreen, you can see the movements of the gators' heads as they rend the flesh asunder.]]
* In "The Mummies of Malenque", a mad scientist and self-proclaimed descendant of the Malenque plans to infect the world with an ancient virus. [[spoiler: However he gets a taste of his own medicine (well, disease) as his ancestors rise from their graves and give him a good whiff of the virus.]]

* In "The Haunted Sonata", the climax includes [[spoiler:the ghost of the original composer of the sonata, who was hidden in the wall of the basement after being pushed down the stairs and breaking her neck, come back to kill the greedy descendant of the man who killed her. She drags him into the wall by the neck and the wall reforms around them, sealing him inside with her red-eyed corpse. Although we later find she didn't actually kill him, we're told by the time he was pulled out of the chamber he'd gone totally insane. We're never told what the ghost did to him.]]

** [[spoiler: The entity in the house pulls the two specialists inside a room where the ceiling begins to descend. The two men desperately try to get out and can be heard screaming their heads off... and then it cuts to outside the door where the ceiling is heard slamming on the floor and the screams stop. Race’s reaction when he opens the door afterwards to see what’s left doesn’t help either.]]
** [[spoiler: The source of the haunting is a malevolent black pearl containing some sort of entity which feeds off human greed. 200 years prior, the pearl corrupted the original owner of the house and his business partner, empowering the partner and cursing the owner with eternal old age. The man wasn't sure what happened to his partner, until we discover exposure to the pearl turned him into some kind of horrible octopus like monstrosity living hidden inside a sealed room in the house.]]

* "In the Wake of the ''Mary Celeste''" is terrifying from the start, with the titular vessel encountering a moving circle of unearthly green light. The crew is driven mad with fear while the captain, his wife and their daughter seek refuge in their cabin. The opening closes with a shot of the trio crying out in horror as the brightening "unearthly" light overtakes them.
