History DoesNotKnowHisOwnStrength / LiveActionTV

* ''Series/TheTwilightZone1959'': In "[[Recap/TheTwilightZoneS3E93TheLittlePeople The Little People]]", one of the giant spacemen accidentally crushes Peter Craig to death when he picks him up to examine him. He feels guilty about it.

** Early on, Kintaros from ''Series/KamenRiderDenO'' suffered from this, or at least K-Ryotaro/K-Masaru(first possessee), breaking everything from park benches to lamp posts.

* ''Series/{{Bonanza}}'': The Season 2 episode "The Ape" used this trope as its centerpiece: a lonely, mentally challenged man named Arnie desperately seeking both love and a chance at owning his own farm causing great physical harm to people who cruelly mock him. Hoss sees potential in Arnie and tries to mentor him, but his efforts are always thwarted by Arnie's desire to marry a barmaid, Shari, who wants nothing to do with him ... and Arnie's own temper and inability to realize that, due to his tremendous strength, he can kill a man rather easily. Hoss repeatedly tries to warn Arnie that he doesn't know his own strength. Before the episode ends, Arnie indeed kills at least two people: a Ponderosa ranch hand who had mocked his slow, awkward ways; and Shari, after he attempts to gift her with an expensive strand of pearls), who slaps the necklace away and tells him he's just a big old, dumb "ape" (Arnie grabs the much smaller Shari by the neck and shake her violently, until she dies). When Hoss realizes what Arnie has done, he tries to get Arnie to understand that he killed someone (and possibly a second person, too) and that he has to go to jail. Arnie then knocks down Hoss and tries to flee. When a sheriff's posse surrounds Arnie, he picks up a huge boulder and attempts to hurl it toward everybody, forcing them to gun him down.

* ''Series/AlteredCarbon''. Lieutenant Ortega doesn't even realise her arm has been replaced by an artificial limb until [[ArtificialLimbsAreStronger she bends a rail]] on the hospital gurney she's lying on.
* In ''Series/{{Angel}}'' episode "Carpe Noctem" Angel's Vampire body is taken over by a DirtyOldMan Marcus who at one point while out on the town, gets into a fight and sends a dude flying [[SuperStrength with a single punch]] causing Marcus to yell "NICE!" in glee.
* ''Series/BionicWoman''. After discovering her MadScientist fiancee has turned her into a bionic woman, Jaime Sommers decides to stop looking for Mr Right and settle for Mr Right Now. At that moment a handsome stranger catches her eye; SmashCut to them making out in the toilet. Unfortunately Jaime accidentally breaks one of his ribs in her enthusiasm, [[MomentKiller putting an abrupt end to events]].
* There's an accidental version in ''Series/BlakesSeven''. In "[[{{Recap/BlakesSevenS4E6Headhunter}} Headhunter]]", a character breaks off the teleport control handle when he grabs it violently. This is nothing unusual given the NoBudget sets, but he's later revealed to be an android disguised as a human, so this trope could be in play also.

** In "Blank", Clark has his memories removed, resulting in him ripping the door to his home from its hinges as he literally doesn't know his own strength.
** Chloe once winced when he grabbed her shoulders with unnecessary force. In "Persona", when Chloe admits she couldn't help with what he is doing, Clark grabbed her arm forcibly, only to let her go quickly. [[spoiler:[[OutOfCharacterAlert It tipped her off that he is actually Bizarro.]]]]
** In "Warrior", a newly empowered superhero accidentally crushes Chloe's hand.
* ''Series/StargateSG1'': In "Upgrades", Jack, Sam, and Daniel are all equipped with an alien wristband that enhances the wearer's speed and strength, if only for a limited amount of time. In the episode, Jack crushes a grip-meter and accidentally takes a chunk out of General Hammond's wall just by lazily kicking it. He also knocks Sgt. Siler off a balcony while trying to high-five him. In this case, said alien tech grants super strength and poor judgement. Siler was a genuine accident. The other two times were demonstrations of his strength, just poorly thought out.
** They also got into a bar fight, earning themselves a rebuke from General Hammond. After all, with their strength and speed, they could have easily killed those guys (especially since Jack is a ColonelBadass).

** In the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E1AmokTime Amok Time]]", we get a look at how strong Vulcans really are when Spock loses control and manages to completely destroy his computer terminal. Other times when Spock loses control he becomes ''really'' scary because of it. In another episode when Kirk had to provoke Spock into a murderous fury to free his mind from an alien influence, he noted in his log that he might die before Spock comes back to his senses. He nearly does.
** A more humorous example occurs in ''Day of the Dove'' when Kang the Klingon sends Kirk staggering with a good-natured back slap.

*** The holodeck malfunctions, replacing characters in a Wild West simulation with recreations of Data, with his approximate physical abilities as well. Some of the characters are weaselly cowards and otherwise unaware of their enhanced strength, but others are the BigBad of the story and also unaware of their strength.
*** In "Masks", an alien probe starts taking over the Enterprise, and Data, who gets possessed by it. At one point, Data grabs Picard's wrist and Picard visibly freaks out as he knows Data could easily crush it (and is possibly already holding it ''way too hard'').

* Provides some of the fun when super-strong-ordinary-girl Do Bong-soon overdoes it in Korean drama "Strong Girl Bong-soon".
* ''Series/{{Supergirl 2015}}'':
** In "World's Finest", a crossover with ''Series/TheFlash2014'', Kara gives Barry a friendly slap on the back, causing him to wince in pain and her to say, "Sorry."
** In "Legion of Superheroes", Kara describes finding a stray cat shortly after arriving on Earth. She fed him, but was afraid to touch him at first for fear of accidentally hurting him. Finally, she was sufficiently sure of herself in that regard to pick him up and pet him, which helped her feel a bit more at home.
** In "Truth, Justice and the American Way", Kara Danvers claims she's not angry after meeting Siobhan. Barry then informs her that she's just broken the phone she's holding.
** In the pilot episode, Kara is fired up after rescuing the plane and greets her sister with an overly energetic hug (complete with cartoony sound effect). Alex says, "Ow!" and Kara pulls back with an apologetic "Sorry, that was too hard."
* ''Series/TheTick2001'': The live-action series has a gag where Arthur shakes hands with the Champion, and Arthur clutches his hand in pain, then the Tick shakes hands with the Champion and the ''Champion'' recoils in pain.

** Number 1 aka Luther has this problem frequently as his [[TopHeavyGuy size]] and [[SuperStrength strength]] guarantees he’ll break something when indoors, at one point when fighting Diego he punches over a statue and later he rips a bar door off it hinges when in a hurry. Still that’s nothing compared to when he’s piss drunk and depressed as Luther casually shoves his brother Klaus, sending the latter flying across the room. In Season 2 after getting fired from his seedy club after losing a match during his DespairEventHorizon smacks the brickwork in his room in frustration making a big hole, to the amusement of his brother Five who’s waiting outside. Luther uses the new window he made, to [[FlippingTheBird flip Five off]].
** [[spoiler: PlayedForDrama with Number 7 aka Vanya once she inadvertently unlocks her [[PersonOfMassDestruction destructive powers]] (that were suppressed since childhood) she damages streetlights and cars while [[PsychoactivePowers angrily ranting]] and when she and her boyfriend Leonard get attacked by three drunk men she accidentally kills two of them. Worse still Vanya in a moment of rage slits her sister Allison’s throat with RazorWind by mistake, which is her StartOfDarkness to becoming a supervillain.]]
