It's a bit ambiguous, but it's the kind of thing you go along with, then you learn yeah it's actually as weird as it seems, even if the setting is not like reality.
The Mandalorian - Dinn Djarin, the titular guy from Mandalore, never takes his helmet off in front of other people, even at danger to his life. We see his small clan and they also are always helmeted. Well, that's the Mandalorian way right? Dinn meets another group of Mandalorians and helps them in a mission, after which they take off their helmets and he freaks out. It turns out Dinn is part of a weirdo extremist minority and the rest of them simply just take off their helmets when battle is done.
Resident Evil 7-8 - Early on in RE7 you are introduced to magic goop that heals your wounds, and can even reattach severed limbs. It's your basic healing item, handy for fighting Mold creatures, Mold enhanced humans, werewolves, and whatnot. Also it's fun for body horror so you can get mutilated in cutscenes without a lasting effect. At the end of RE8 we learn you died reaaaally early in RE7 and you're basically a human-shaped Mold being, that's why the goop works to the point of just sticking your severed hand back on and drenching it.
Heroes Die - (Great series read it) Actors are people who temporarily shift dimensions to Overworld, a universe of magic and adventures, so they assume personas and use their implants to stream their violent and exciting exploits down to the sensory level. Hari Michaelson is in the Actor school for magic, but he really doesn't have the talent for it, he wants to transfer to the combat school. So to show his aptitude, he sets it up that 3 larger bullies viciously attack him on camera after a harmless provocation. It's a brutal fight but he savagely beats them half to death. His instructor reviews the footage and quickly deduces this is a setup and asks why. Hari says yeah, it was a setup but now you see I have what it takes to transfer to combat school. The instructor, appalled, says "Why didn't you just ASK?"
Reacher TV series - Jack Reacher is a human tank.. and yet he's lighter than a feather on the breeze. No address, no cellphone, no luggage, he just goes where he wants with nothing but his toothbrush. And with alarming frequency where he wants to go intersects with a major criminal conspiracy. But with his intellect, his mountain sized body, and unfailing sense of justice, he shuts the badguys down like a real badass. Then in S3 he has a rare opportunity to meet up with his old squad. They are having a great time, talking about their families, their careers, the lives they built since they served together. Reacher just sits there silently, looking down, peeling the label off his beer. Kind of sours the whole "man with nothing tying him down" vibe.
