Nightmare Fuel / Gerry Anderson's New Captain Scarlet

• The Mysterons evoke the same feeling of Nothing Is Scarier as their original depiction in the show. If anything, this new iteration of the Mysterons is even more terrifying than the original series. In the puppet show, the Mysterons at least provided either a direct or cryptic warning as to what their intentions were. Here, the Mysterons offer no such courtesy and always seek the most destructive route possible in their war of nerves. As such, Spectrum is kept on their toes and any incident, no matter how small, must be investigated.
• At of the 2nd episode of Instrument of Destruction Black kills business man by driving him to the scrapyard and trapping him to be crushed in the car crusher and he is the first person to be killed by Black with Mysteron replica of him cancelling all plans and he never seen again after the episode.
• The Mysteron-infected robotic bugs in "Swarm". They can eat through metal and nearly kill Destiny by eating her jet. They also have the ability to breed meaning that one getting aboard the Skybase leads to hundreds of them being born within minutes. But the most horrifying thing is what they do to poor Lieutenant Green. They wrap her in a cocoon and probe her mind for information on the Skybase so they can figure out a way to crash it. Scarlet manages to stop them but the sight of him being attacked by a swarm of the insects is also terrifying.
• The RAT (Remote Aquisition's Technology) from "Rat Trap". It's a robotic probe that was created to study in hostile environments on Mars but was taken over by the Mysterons. Throughout the episode, the RAT proves to be quite the Implacable Man, being immune to the heroes' weapons and nearly killing Captain Blue with its diamond-tipped saw.
• The Mysteron Replicant of Lieutenant Green's father Commander Lewis invokes a lot of this in "The Homecoming":
  • When Dr. Gold attempts to draw blood from him to make sure he isn't a replicate, Lewis wakes up and hypnotizes the doctor into using the syringe on himself and then using his own blood sample to fake the test results. Seeing the old doctor futilely struggle against the Mysteron's control is truly unnerving.
  • His "sparring" session with Captain Scarlet very quickly escalates to him trying to kill Scarlet. Where it not for Green showing up at that moment, who knows what would have happened.
  • His plan to rig an antimatter reactor to blow, leaving nothing but a smoking hole from California to Texas and taking 8 million people with it.
  • Just picture all this from Green's perspective. She gets her father back after all these years only to discover he is now a Mysteron and is planning to murder her, her friends and all of humanity. It's both horrifying and heartbreaking.
  • Towards the end of the episode, the replicant taunts Serena, by telling her just how her father died. Like his comrades, he died inside a faulty cryo chamber, screaming for help. Talk about needlessly cruel and thought-provoking.
  • Then, in what doubles as a massive tearjerker, just before Scarlet saves the day, Commander Lewis manages to break free of the Mysteron's control. Knowing that he will not remain free for long, Lewis pleads with his daughter to kill him, both to stop the creature from controlling him and end his suffering.
  • A town in the episode A Storm at the End of the World is massacred (including children) by a mysterioned soldier in a tank.
  • In A Trap for a Rhino the Mackenzie's killed brutally with Mrs. Mackenzie being burnt alive offscreen by the Mysterons and Harmony's cadet Johnson' has coffee poisoned by Mystrons which kills him.
  • Touch of Reaper Has a disease called the razer virus that kills a doctor and his assistant named Dayna and Micahel while they were trying to make a cure they kill some people offscreen by the Mysterons with disease and with Dyna kills her TV reporter boyfriend with a kiss and When King is captured his body limps over with no irises the Mysterons reveal what they are planning soon as it finishes King disappears a Mysterionised Lykid attempts to kill the President of the United States with his touch he manages to infect Scarlet but Scarlet is able to defeat with him falling out of the sky to his death
