* The planet Chimera in ''Manga/JyuOhSei''.

** As of Chapter 263, we see the creatures that can survive such an environment. [[spoiler: The Four Beast that nearly killed the human world is revealed to be nothing more then an ant in the grand scheme of these creatures. This included a massive Stronghold Rhino, a powerful humanoid multi-armed Thunderous Devil that makes volcanoes seem only as big as anthills underneath its feet, itself dwarfed and nearly stomped on by an even bigger Ficasdaltonphant, with a flying dragon like creature overhead that's stronger than ''that'', only for that to run away from a fully-grown Battle Wolf. To put this in perspective, the Four Beast had a Capture Level that maxed out at 350. The beasts just mentioned range from ''972'' to '''6,090'''. And this is all before we even get started the titanic beasts that ''rule'' these inhospitable lands. The tl;dr is that the [[ThingOMeter Measuring Tongs]] weren't ''made'' that can read them properly.]]
** That would be the Eight Kings. Each one has a capture level over 6000. They include a 22-kilometer horse that can create vacuums and send columns of air straight through the aforementioned massive planet by ''breathing'', a monkey that plays by throwing mountains around the world, a whale with a literal black hole in its stomach, a deer the size of a '''''continent''''', a snake as long as ''the circumference of the world'', a crow that can kill anything by casting its shadow on it, the aforementioned Battle Wolf (actually one way stronger than the level 6090 one), and a huge dragon that can fire planet-busting beams.

** The Swindler's Swamp is an exceptionally dangerous area, even to Hunters. The Swamp's entire ecosystem has evolved around deceiving and eating humans, with such friendly wildlife as "man-faced apes" which go out to masquerade as humans and lure them back to the swamp. Swindler's Swamp is used as staging ground of the second phase of the Hunter Exam that Gon and company take. The goal is simply to reach the other side. Everyone who reached this phase is a 1 in 10000 badass. Out of a group of a few hundred, only ''150'' make it out alive. The rest became lunch [[spoiler: or were killed by Hisoka]].

* The world of ''Manga/{{Toriko}}'', as it is filled to the brim with animals that are strong enough to level cities (creatures are given capture levels, and monster with a capture level 5 or higher can topple tanks singlehanded), the worst place being the Gourmet world, a region which basically encompasses 2/3 of the planet, and was originally thought to be a paradise since no one who went there ever returned, until someone actually did return, and revealed that it was in reality a hell that would kill a normal person almost instantly and even trained professionals who are considered superhuman can't survive without considerable training. Chapter 259 reveals that Gourmet World [[spoiler:was created when a Gourmet Cell infused meteorite struck Earth. The Gourmet Cells absorbed energy from Earth's mantle and grew additional landmass. "Human World", the safest part of the world, is the original Earth. The reason Gourmet World is such a hostile and alien environment is because it was spawned by something from the depths of space. And apparently, this alien being did this on purpose. It's fattening the world [[PlanetEater for dinner]].]]

* ''WesternAnimation/{{Trolls}}'': Setting foot outside the Trolls' warren is basically signing your own death warrant. The forests are filled with bizarre predators constantly devouring each other, the plant life is poisonous, and the weather can change from mild to blizzard to boiling at the drop of a hat. And everything is painted in cheerful pastel colors.

* ''Series/TheMandalorian'': While Mandalore wasn't exactly a paradise before (contrary to what Din has been told about it by the [[{{Cult}} Children of the Path]]; see ''WesternAnimation/StarWarsTheCloneWars'' under Western Animation for more details) the planet became ''even more'' inhospitable after the Empire ravaged the planet's surface, turning it from a war-torn desert to a ball of glass. While the air is still breathable (contrary to initial reports), the upper atmosphere is wracked with electromagnetic storm clouds, the Empire's fusion bombs destabilized the planet's magnetic field (making communication outside the atmosphere impossible), and various hostile beings of varying sapience have moved into the ruins of Sundari, including some bio-mechanical creature of unknown origin that has kidnapped and harvested the blood of several Mandalorians.
