Deep-State Corporate Cover-Ups (K-Pop: Demon Hunters)
During a subway train fight, Huntrix failed their mission and let the swarm of demons suck the souls out of an entire train car full of commuters, vaporizing their physical bodies instantly and leaving nothing behind but piles of clothes. Because background news reports explicitly show that "missing persons cases have tripled" across Seoul, we know the victims aren't magically erased from history by their families cause their loved ones are still actively grieving them. This means the girls' management agency operates a deep-state shadow government that sits entirely above national law; to protect the group's brand image, the corporate executives must actively bribe thousands of grieving families, weaponize the mainstream media to gaslight the country into normalizing mass disappearances, and completely confiscate or erase government CCTV surveillance footage before the police can even arrive. If it's only a few individuals then it can be filed as normal missing person reports, but a whole train of passengers vanishing would definitely make into global news outside of South Korea yet the general public is still not aware of demons.
The Baby Corp Supply Chain (The Boss Baby)
Because all babies are manufactured on a giant conveyor belt at Baby Corp and sorted into "Management" or "Family Material," traditional human biology is completely irrelevant. Adult humans in this universe possess no biological reproductive capabilities, meaning humanity has completely broken off from Earth's natural evolutionary tree to become a species of corporate-manufactured clones. To make it even darker, official timelines reveal Baby Corp has existed since around 100,000 B.C., meaning that while prehistoric humans were discovering fire and painting on cave walls, a celestial corporate board of directors was already sitting in a high-tech skyscraper, drinking anti-aging formula, and managing the planet's population. Who even built Baby corp and do they just skip basic biology class at schools ?
Basically everything about this franchise (Cars 1/2/3 )
In Cars 2, they go through intense airport security checkpoints where they have to take off their tires like shoes, and in Planes, the Twin Towers are visibly missing from the NYC skyline meaning a Car 9/11 is absolute canon. Because planes are sentient living beings, it means aircraft were either radicalized into willingly committing acts of mass terror or were violently hijacked and forced to use their own screaming, living bodies as weapons. By extension, this means Car World Wars, a Car Hitler, and probably a Car Jesus too due to the existence of the Catholic Church via the Pope. On top of that, their society is built on a brutal caste system where your shape determines your freedom; if you are born a Ferrari, you are a wealthy celebrity, but if you are born a commercial jet/train/cargo ship, your anatomy dictates you are a literal slave-class, destined to spend your life parked in isolation and can't have social life because of your size, opening up your torso to let other cars sit inside your internal organs. Not to mention there are vehicles that get treated as animals ( the cows, insects and birds )
=> These are like details that were never really specified during the show or magically handwaved away but audiences can deduct by themselves from watching, a rabbit hole you may say.
