Nightmare Fuel / Life After People

An abandoned city is pretty creepy on its own; an entire world without people is much, much worse.
     Original special 
  • Total blackouts worldwide following mass power outage just a day or two after people count, and it pretty much warms up the viewers of what else is to come.
  • Seeing-eye dogs, particularly ones with breeds, fending or trying to fend for themselves. Especially as most of them aren't suitable for such a situation without humans. The thought that our precious friends will become vicious hunters. The notion that animals will forget you and humanity in due time. The fact that the smaller and weaker pets, such as toy breeds, will not survive along with some of the more poorly designed breeds.
  • Eventually, given millions of years, there will be no trace of evidence that we humans were ever here, save for perhaps some fossils if we get so lucky. All of our achievements, all of our buildings, all of our records now lost and buried with time. Like we never existed in the first place.
  • Seeing your home city being abandoned in the series combines both Nightmare Fuel and Tear Jerker.
  • Prypiat, Ukraine. A ghost town which residents evacuated after the Chernobyl disaster. And they just HAD to add creepy child laughter in the background, too...

     The Bodies Left Behind 
  • Mixed with a heavy amount of squick, the eventual decomposition of all human remains in general, particularly those in cryofreeze.

     Outbreak 
  • Atlanta would be overrun with kudzu. However, when the kudzu dries up, it forms a tinderbox. Once lightning strikes, the kudzu ignites and burns down most of Atlanta.

     The Capital Threat 
  • The entirety of Los Angeles being engulfed by a wildfire 10-15 years after people is really unnerving.
    • This is topped by an earthquake 50 years after people that makes quick work of most of LA.
  • Washington D.C. being flooded.

     Heavy Metal 

     The Invaders 

     Bound and Buried 
  • A San Francisco cable car's cable snaps, sending it careening downhill. It goes so fast that it ploughs through a car.

     Sin City Meltdown 

     Armed and Defenseless 

     Road to Nowhere 
  • An oil refinery near Houston explodes just an HOUR after people.

     Waters of Death 

     Wrath of God 
  • Christ the Redeemer's eventual downfall. Firsly, as the time goes on, the statue's hands plummet on the ground below. Eventually, the statue itself collapses after being covered by plants.
    • Actually, the whole episode may be terrifying if you are devoted to God.

     Toxic Revenge 
  • The dead zones around nuclear power plants.

     Crypt of Civilization 
  • The fate of the titular "Crypt of Civilization".

     The Last Supper 
  • Abandoned supermarkets. Especially the meat and deli departments. All that rotting food is the stuff of nightmares...
  • The clouds of sugar dust in a refinery igniting violently. We get to see the fireball race along the conveyor belts and catwalks before hitting the silos. Eventually, the fires get so hot that the moisture in the concrete structures turns to steam and the entire plant explodes like a bomb. Worse, it's stated that at least 4 such fires occur in the U.S. every year.

     Home Wrecked Home 
  • The gas explosion in the empty kitchen which happens just a single day after people.
  • The San Remo apartments burn down after rags soaked with linseed-oil paint spontaneously combust.
  • The collapse of the Burj Khalifa in Dubai.

     Holiday Hell 
  • Salton City. A once bustling resort town turned into what could best described as "desert with a lot of trash in it".
  • The power in Christmas shop going out in the beginning. Unlike previous episodes, where the power grid failures were not given special attention, in this episode, as the power goes out, the Christmas song which had been playing even after people were gone, becomes more and more distorted until it completely fades into obscurity. Also, it happened during the very first day after people, while in other episodes, it took up to several days for power grid to fail completely.

     Waves of Devastation 
  • Just 10 years after people, Sacramento's Folsom Dam will break and the resulting floodwaters would demolish everything in the city.
  • Similarly to Sacramento, many cities in the Netherlands would end up flooded within months.

     Sky's The Limit 

     Depths of Destruction
