Surprisingly Super-Tough Thing is when an inanimate object, building, or vehicle is attacked with futility, even though the attackers expect it to be outright destroyed.
However, the futility of the attack has nothing to do with the actual vulnerability of the object. The object can even be a vase made of paper thin glass; all things being relative, what's Made of Indestructium to an ant is Made of Plasticine to a human. The key word here is "surprisingly": this trope isn't about objects that are indestructible, it's about objects that are surprisingly so to an attacker who expects their destruction (or at least destruction from their initial attacks. If they change their weapon or adjust their technique which succeeds in destroying the object, then their failed first try still counts toward this trope).
Interestingly, this trope is omnipresent in video games. Since every object that doesn't have a damage model coded for it is effectively invincible barring exploitation of glitches, many players invoke this trope when using their weapons on random things lying on the ground instead of enemies.
Be aware that when adding examples, be sure that A) There is a building, vehicle, or item B) a character judges that thing to be destructible within their abilities, and C) the object is attacked with very little to no effect. Be especially careful with B; a character attacking something they know they can't destroy because of instinct, desperation, mind control, or spite does not count. Regardless of the quality of their judgement, if the character in question believes they can harm or destroy the object in question, requirement B is fufilled. Even if omnipotent gods have failed to destroy the MacGuffin, if Average Joe is stupid, arrogant, mentally ill, or intoxicated enough to think his mortal punches will crush it, then it counts.
For things that really are indestructible, and not those that just seem that way, check out Made of Indestructium. If a character's most powerful attack or weapon invokes this trope, it can overlap with The Worf Barrage. Compare No-Sell, which is more about characters fighting each other than failing to destroy inanimate items. Tonka Tough toys may invoke this trope in real life.
- Late in Dragon Ball Z, the legendary power of the Z Sword is tested against a brick of Katchin, the densest metal in the universe. Everyone think it will be short work because not only is it a legendary sword, but everything in the universe is Made of Plasticine around the ridiculous power of the heroes. They all get a nasty surprise, though, when it breaks the sword.
Goku: I guess it's not called "the hardest metal in the universe" for nothing...
- A segment in the final episode of Nichijou features Mio and Yukko going to greater and greater extremes in the course of trying to break open a pumpkin.
- A Certain Magical Index: Accelerator, in a fit of rage, once attempted to destroy the Windowless Building which houses Academy City's leadership. He did this by throwing an entire skyscraper at it at multiple times the speed of sound. Result? Not a scratch (though the thrown building was totally pulverized). Later novels note that the Windowless Building is made out of some kind of self-aware material named "Calculate Fortress", which is able to alter its composition and vibration properties to withstand any amount of force. The only way to break it is to exploit logical weaknesses in its self-altering procedures.
- Dune: Paul tells the Fremen about an obelisk "cut from your hardest rock." He has them kick it, yell at it and cut it with a laser. Nothing. Then he blasts it with the weirding module and shatters it.
- In the Hilarious Outtakes of Toy Story 2, Buzz and co use Rex's head as a battering ram to open a gas vent, and fail. (They succeed in the actual story.)
- In The Lord of the Rings: The Fellowship of the Ring, Gimli tries to destroy the One Ring. His axe shatters upon striking it. Elrond then explains that the Ring can only be destroyed in the fires of Mount Doom.
- Marvel Cinematic Universe:
- In The Avengers, Thor tries to break out of a containment cell built for the Hulk. He's surprised when it actually holds against his first hammer hit. After he's been dumped with the cell into free-fall, he adjusts his technique and flies straight at the crack he made with the first hit, breaking through.
- In Thor: The Dark World, it's Thor again, this time trying to destroy the Aether (which once resisted the entirety of Asgard's power) with the hammer Mjölnir. It fails.
- In Independence Day the US military launches a nuclear missile at a city-sized alien spacecraft. The ship's deflector shields repulsed normal missiles from jet fighters earlier, but everyone is truly demoralized when the intense fireball explosion subsides, only to reveal that the alien craft hasn't even suffered a single scratch.
- In Monty Python and the Holy Grail, there's a brief shot during the first French castle attack where Lancelot is visibly stabbing the wall. Granted, Lancelot's Ax-Crazy, but some of the other knights are seen hacking at the wall in between being pelted with farm animals.
- In Breaking Bad, Walt attempts to break a window in Ted's office building with a plant decoration. He does not succeed and is escorted out by security officers.
- In Just Shoot Me!, Dennis gets an ugly home-made vase Jack made in pottery class. Dennis tries to "accidentally" break it, but no matter how hard he drops it, the vase proves indestructible.
- In the Scrubs episode "My Best Laid Plans" Turk's phone withstands, unharmed, J.D. hurling it to the floor then stamping repeatedly on it, and being thrown from a fourth-story window.
J.D.: This phone is indestructible, if it has a camera I am so getting one!
- In The Goldbergs episode "Kara-Te", Barry signs up for a school talent show. Onstage, he attempts to break a wooden board with his martial arts skills, but it fails hilariously with the board not even cracking.
- The Star Trek: Deep Space Nine episode "Valiant" had the eponymous Defiant-class fire a modified torpedo at a Jem'Hadar dreadnought, expecting it to disrupt the ship's antimatter containment system. Cue titanic explosion, only to have the dreadnought come out of the fireball with no apparent damage and blast the USS Valiant to pieces in minutes.
- Stargate SG-1:
- "The Serpent's Lair" has the Air Force fire a pair of ballistic missiles tipped with 1-gigaton naquadah-enhanced nukes at a pair of orbiting Goa'uld Ha'tak-class motherships. Apophis and Klorel raise shields and the missiles impact rather pathetically to no effect whatsoever.
- In "The Quest, Part 2", the team searching for the Sangraal is faced with a dragon. They eventually settle on trying to blow it up by throwing all their C-4 in a bundle at it. Teal'c grabs the makeshift satchel charge and throws it at the dragon, trying to hit the underside because Cam thinks that's where dragons are weakest; it turns into Feed It a Bomb when the dragon snaps it out of midair, swallows it, and has the C-4 go off in its stomach to no effect whatsoever. The Oh, Crap! look on Teal'c's face is hilarious.
- The Teaser of "Revelations" has Thor's starship Beliskner fire on a Ha'tak. The Asgard had long held a technological edge over the Goa'uld, but this time the Beliskner's weapons do absolutely squat. In the ensuing off-screen battle the Beliskner is destroyed and Thor captured.
- The first encounter with a Kull warrior in "Evolution, Part 1" has Teal'c and Bra'tac shoot at it with staff weapon and zat guns, since in this 'verse armor is usually useless. The weapons have no effect, but luckily for them it keels over from unrelated cardiac arrest about five seconds later.
- In one episode of Angel, Doyle attempts to ram a gate in his car, but the gate holds.
Doyle: Damn, that's a good gate.
- In a famous episode of The Twilight Zone, a father finds that his daughter's "Talky Tina" doll can't be destroyed by any of the power tools in his basement, which include a rotating saw blade and a blowtorch.
- In Red Dead Redemption, there are lanterns in towns which you can vandalize, and dynamite crates which blow up when shot. You can also shoot the "arms" off of cacti.
- In the text based RPG Mobile Armored Marine, your character must get past a heavily fortified door to continue the mission. One of your options is to try to blast it away with your weapons. That will fail, much to your described (remember, it's text based) surprise. However, after that you have the option of piling all your grenades against the door, which will work. The first plays this trope straight, but the latter part of this example inverts it.
- In Devil May Cry, all objects that can be interacted(meaning it reacts to an attack) with are breakable, with the following exceptions:
- "Red/blue devices" (Basically, switches in the form of a a pedestal with a ships's-wheel-like thing on it or a shield in the case of DMC) which appear throughout the original franchise which can only be activated by Dante/Nero/Vergil's only means of interacting with the environment: attacking it. They won't break even if you use the character's strongest attack, though they'll activate faster if you do that.
- Combat Adjudicators in DMC 3 & 4. They react to weapon attacks but not firearms. And they are invulnerable except for their Kryptonite Factor Element or character (either Nero or Dante).
- DMC 4 has Gyro Blades, torch/top-like devices which at least have the excuse of being sturdy enough to destroy indestructible doors and pedestals. slashing it once it's ignited will make it spin faster and move faster when launched with the Devil Bringer.
- The Giant Dice from the same game which activates a Board Minigame, Nero can shoot, slash, and punch it all he wants and it will never break. Later subverted when it turns out you can actually destroy it, which Dante does by pulling off a Diagonal Cut on it before it activates the minigame.
- Deus Ex has a notable example in door confusion. Most locked doors go and tell you whether or not they can be battered down or blasted open, and is shown as effectively a health bar. What isn't shown is how damaging a weapon it takes to actually damage it. This sometimes, but not always, corresponds with how much health it starts with. Sometimes you can crowbar your way into a door only to later find a door with the same amount of health that said weapon can't scratch. Likewise, after finding the Dragons Tooth Sword and maxing out the low-tech weapons skill, many locked doors with finite durability can be destroyed with it. Then sometimes you encounter a fairly low-durability door that still shrugs off everything sort of explosives.
- A Looney Tunes cartoon, "Much Ado About Nutting", features a squirrel getting a hold of a coconut and finding it harder than normal to break open. This escalates until the coconut is dropped off the roof of a skyscraper and leaving only a crater in the street, before falling off of it's stand and finally opening... revealing another coconut shell.
- Sometimes, when police raid a building, they may find that doors that look normal from the outside are quite strongly reinforced and barricaded on the inside.
- 1967: Missouri Tigers football coach Dan Devine tried to motivate his team for the upcoming game against the Nebraska Cornhuskers by playing the Cornhuskers fight song over and over again, whose band played it every time they scored a touchdown. On game day he picked up the record and said "I never want to hear this song again!" and threw it down on the floor, expecting it to shatter. Instead it bounced up into the air. He tried the floor again and failed again. He picked it up and bent it, but it still wouldn't break. He hurled it against a wall and it bounced back again.
Dan Devine: I don't know when I've ever been so embarrassed and humiliated. Finally, I just went over to a window, opened it, and threw the record out. Then I got out of there as fast as I could.
- Despite the pep talk setback, the Tigers went on to win the game 10-7.
- As stated in the description, those plastic and/or metal playthings can be known to be quite surprisingly formidable, what with being mere toys.
- During the Battle of Stalingrad, a 30-man platoon of Soviet soldiers were ordered to defend an apartment building and hold the surrounding blocks of the city. The Nazi forces, certain that this would be an easy victory, set out to capture or destroy the strategically-located building. What began with orderly assaults soon devolved into a 58-day-long Zerg Rush that threw entire divisions of troops, tanks, heavy artillery, and air raids at the structure. At the end, Pavlov's House was battered but still standing and uncaptured as the Red Army's counter-offensive arrived to retake the city.
