"A flashy feature that has limited usability for victory."

* Marvel's premier CloakAndDagger organization, [[ComicBook/{{SHIELD}} S.H.I.E.L.D.]], prefers to operate out of a Helicarrier. It's an AirborneAircraftCarrier , and it's exactly as cool as it sounds. Unfortunately, it tends to crash. A lot. This typically causes about as much destruction as you'd expect from dropping something the size of an aircraft carrier from about a mile up, and usually has the inadvertent effect of releasing whatever superpowered psychopaths, alien viruses, etc. that happened to be locked up there at the time.
** Helicarriers fall victim to TheWorfEffect so often that in ''SecretAvengers'', it is shown that S.H.I.E.L.D. actually has a sign counting down the number of days since their last Helicarrier crash.
** Helicarriers have appeared in exactly two [[MarvelCinematicUniverse MCU]] films: ''Film/TheAvengers'' and ''Film/CaptainAmericaTheWinterSoldier''. Both films featured their Helicarriers either crashing or very nearly doing so.
* Nite Owl II was the embodiment of this trope in ''ComicBook/{{Watchmen}}'', spending millions on awesome but impractical hardware. His famous quote:
--> "Who needs all this hardware to catch hookers and purse-snatchers?"
** The most awesomely impractical invention was his exoskeleton, which did grant him super-strength but also broke his arms the first time he used it.
** In the same mythos, there is old-timey superhero Dollar Bill who is shot to death by common crooks when his corporate-mandated-cool-looking cape [[CapeSnag gets caught in a bank's revolving door]].
* The Cosmic Cube... you can do almost anything as long as you are thinking about it. Want D.C. to be a lake of fire? It will be, until you fall asleep. Then everything's back to normal and the heroes are kicking your teeth down your throat. In fact, anything you allow yourself to think about will take on some degree of reality and if you dream, that becomes real too. Even DoctorDoom couldn't handle it for very long.
** {{Lampshaded}} by TheFalcon at one point, who noted that the damn thing never works right and almost always backfires on whoever is trying to use it. He went on to suggest that there may be some ''[[TheMonkeysPaw Monkey's Paw]]''-style [[BeCarefulWhatYouWishFor karma]] involved.
** DependingOnTheWriter, the suckers aren't actually that hard for alien civilizations to make. The Skrulls had one. Even us humans have made a couple. It's just a matter of learning the hard way that the little suckers are [[ForbiddenPlanet id monster]] factories, and then you don't make them any more.
* TheUltimates for a while. A multi-billion dollar super-squad just sitting around because they caught all the bad guys? Well, rescuing people from a fire is cool but we got guys for that.
* Of all of the Batsuits made, [[{{Azrael}} Jean-Paul Valley's]] suit during ''ComicBook/{{Knightfall}}'' fits this, especially the final variation. Massively flared out armored cape segments, built-in flamethrower, armor from head to toe. Can't fit through small spaces, easily ignite yourself from leaking gas and you gotta be superhumanly strong just to move around in that thing like you were Bruce Wayne himself.
** Ironically, Jean-Paul would discover this with Batman's cape - long and billowy, but it has way too much drag. Dick Grayson, during his second tenure as Batman, would complain about the cape as well as it got in the way of his more acrobatic style.
* If [[ComicBook/AntMan Hank Pym]] is any example, turning yourself into a giant seems to be a rather impractical power for a hero. You never have enough room to move around, you're always in danger of breaking stuff or hurting someone by accident, and you're a target the size of a barn. Then again, if you're a villain who just wants to randomly smash stuff, it's pretty awesome.
** Emphasized even further in TheUltimates, where it's shown that the very act of getting his costume on (which unlike his 616 counterpart, does not shrink or enlarge itself to accommodate his changes in size and thus must be stored in a nearby warehouse when not in use) requires several hours of preparation. If he wants to use his powers as a spur of the moment action, he has to do it in his birthday suit.
* Adamantium. Sure, it's indestructible, but it's incredibly rare, prohibitively expensive, and almost impossible to work. You can't recycle it, either: Once it's been worked and set into a particular shape it can't be reworked. Oh, and it's highly toxic, too. The only reason ComicBook/{{Wolverine}} can even live with his indestructible skeleton is because of his HealingFactor, and the very presence of the adamantium in his body greatly impairs his ability to heal. Oh, and it's magnetic, so indestructible or not, it's pretty much worthless if you're up against someone like SelfDemonstrating/{{Magneto}}.
** The toxicity thing only gets applied to Wolverine though, as several other characters have been laced with Adamantium without the benefit of an advanced healing factor (Bullseye, Hammerhead, Lady Deathstrike) with no ill effects. Occasionally handwaved by them taking medication to counter the poisoning.
