* ''UFO: Extraterrestrials'' goes with this while also introducing elements of LensmanArmsRace - while the aliens are clearly technologically superior in many ways (and general scope of their invasion fleet), there's also a definite back-and-forth with humans reverse engineering alien technology, adapting it into something better, and the aliens responding with their own riffs on the human improvements.

* The aliens in ''VideoGame/{{XCOM}}''. Interestingly, all XCOM games so far have the titular organization stealing technology from the dead alien bodies and reverse engineering it to use it against those who introduced it, performing AlienAutopsy on those bodies they recover to learn about the alien's cybernetic technology, and so on.
** The spiritual successor UFO: Extraterrestrials goes with this as well, while also introducing elements of LensmanArmsRace - while the aliens are clearly technologically superior in many ways (and general scope of their invasion fleet), there's also a definite back-and-forth with humans reverse engineering alien technology, adapting it into something better, and the aliens responding with their own riffs on the human improvements.

* ''Film/{{Outlander}}'': Features a Norse Viking population suddenly being violently attacked by [[spoiler:an intelligent, nigh indestructible creature, driven to anger and desperation by the genocide of its entire species on a distant planet]]. Mostly they refer to it as a dragon, sometimes as a demon. Luckily they have an OutsideContextProblem to help them.

* In ''Manga/{{Hengoku no Schwester}}'', the protagonist is on the wrong end of a WitchHunt by the church, and forced into their monastery. And while the story is set in 1542, the KnightTemplar church is shown to possess technology from later ages and hoards them jealously. For instance, they are able to conduct rudimentary blood transfusion and know the concept of blood types; for reference, the first recorded successful blood transfusion is in 1665. The church also employs a girl gifted with EideticMemory, able memorize an archive's worth of books at a glance and recall it perfectly, which the church uses as a human computer database. The church leader also believes that TheWorldIsNotReady for such knowledge, and the way she explains the potential of people being hunted and milked for their blood, [[VillainHasAPoint it's hard to argue that she's wrong.]]

** This is the entire point of the movie ''Film/{{Predator}}'': five heavily-armed military men hunting down a missing cabinet member when suddenly... technologically-advanced alien hunter!

** Interestingly, this also applies to the enemy faction. [[spoiler: Marley has held military superiority over the rest of the world for over a century by weaponizing Titans. Unfortunately for them, the other nations have slowly advanced to the point that they are starting to roll out weaponry and vehicles that are more practical and effective than a rampaging horde of uncontrolled naked giants could ever be. The Marleans know that it's just a matter of time until their enemies develop technology renders their Titans obsolete and end their dominance. The reason they're so desperate to attack Paradis is that they need to obtain the power of the Founding Titan to turn the tide before that happens.]]

* ''WesternAnimation/ThunderCats2011'' presents [[BigBad Mumm-Ra]] this way to the Cats, as he and the LostTechnology his armies use have both been reduced to superstitions and legends in the centuries since he was first defeated by their ancestors.

** What makes the Reapers so devastating is that the scale and capabilities of the Reapers sits outside of the context of the Citadel's military doctrine. The three primary Citadel species have geared their militaries to cooperate and specialize, with each species supporting one another: the turians serve as the primary heavy combat element, supplying most of the ground troops, armored vehicles, and spacecraft. The asari provide elite biotic special forces and economic and diplomatic clout, at the expense of heavy combat units. The salarians provide advanced technology, intelligence, and covert operations units at the expense of heavy combat elements as well. This works just fine for the enemies that the Citadel is accustomed to fighting. But when the Reapers show up, they're so fast, they have such huge numbers, they have nonexistent logistics requirements, they have technology that at times breaks the laws of physics, and they have firepower and armor more powerful than anything the other races can even hope to achieve, which means they can attack ''anywhere'' at their leisure. As a result, the asari military gets smashed and the salarians only survive the majority of the war because the Reapers haven't bothered with them because their intelligence apparatus (geared to fight more conventional enemies) is a nonthreat. The turians are the only ones who spend the entire game in a (losing) slugging match over their homeworld.
