* ''ComicBook/RickAndMortyOni'': Knowing that the dinosaurs in his island were specifically bred to be subservient to him, Summer dresses up as Rick to rescue him from the angry workers he’d abandoned there. She and Morty don’t realize that a bunch of huge carnivores would eat them until after it had happens.

* ComicBook/{{Supergirl}}: Some of her adventures provide good examples:

* Franchise/{{Superman}}:

* ''Franchise/SonicTheHedgehog'':
** ''ComicBook/SonicTheHedgehogArchieComics'':
*** This is a recurring problem for Sonic. Pre-reboot, this nearly cost him his friendship with Tails when he, hurting over a recent breakup with Sally, pursued a relationship with Fiona despite full knowledge of Tails' own crush on her. When Tails confronts him about being so insensitive over it in issue 179, Sonic explains that he knew that Tails liked Fiona and that she had no interest in him, so he went out with her to prevent Tails' own feelings from getting hurt and hoped it would help him get over it, while acknowledging that it was a spur of the moment idea and he didn't think before he took action.
*** Lien-Da has this as a FatalFlaw. She's never much for planning and more acting when an opportunity sees itself, but never seems to think what to do past a certain point in action or what her opponents are really capable of. This nearly gets her killed when she has the bright idea to attack the Iron Queen, a {{Technopath}}, when she herself is a {{cyborg}}; she goes down like a chump thanks to the Queen activating the ExplosiveLeash Eggman had installed in Lien-Da's cybernetics, and the only reason she survives at all is because Eggman decides to rebuild her. This is also what cost her a leadership role in the Dark Legion: her and her brother Kragog were planning on murdering their father so they could both be leaders. Just so happens she didn't even think that her brother would double-cross ''her'' as well and while she survives the weapon that killed their father blowing up on her, Kragog steals the leadership role under her nose.
*** At the end of ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'', Eggman is so outraged that Sonic has ruined his plans for the Super Genesis Wave that he deliberately interferes with Sonic's ResetButton attempt, declaring that he would rather let reality be destroyed than let Sonic restore it to the way it was. Not only does his interference directly result in a CosmicRetcon, but the residual energy left behind by the Super Genesis Wave ends up ripping Sonic's World apart and awakening [[EldritchAbomination Dark Gaia]], leading into a ''VideoGame/SonicUnleashed'' adaptation. With all of this, Eggman admits that his actions were "[[{{Understatement}} a bit hasty]]."
*** Princess Undina thought she could use pirates to her advantage to travel the world, since she was too valuable a ransom, as well as the fact she can use the Mystic Melody to locate ruins which could potentially contain treasure as payment for the travels. However, considering she was dealing with pirates, she didn't take into account the fact that they would be too greedy to listen to reason about certain warnings on the ruins they raided, or the fact that they may discard her if they get something more valuable. She especially gets worried when Shellbreaker admits to wanting to invade her home once he get his hands on a supposed weapon she found.
** ''ComicBook/SonicTheHedgehogIDW'':
*** In Issue 18: Sonic comes across two villagers who opt to burn down the forest around Cream's village to prevent the [[UnwillingRoboticisation Metal]] [[ZombieApocalypse Virus]] from spreading. Sonic furiously calls them out on this, pointing out that though it'll stop them from getting infected and prevent the virus from spreading, they'll just get consumed by the forest fire instead; the villagers in question can only stammer in response, having failed to consider that.
---->'''Sonic''': Cream gets to hang out with me because she's got some sense!
*** Orbot reveals to Dr. Starline that this is one of the main reasons Eggman always loses: he has big ideas and big executions but often rushes things without thinking long-term and devolves into his hatred of Sonic, which costs him every time. No better is this displayed than in the Metal Virus arc. While Starline opted to conduct more tests to realize the extent of its capabilities, Eggman decides to use it [[UnfinishedUntestedUsedAnyway the moment it appears to work]], reasoning that he can fix any bugs later as they crop up. This leads to the Zombots slowly getting out of control, to the point they begin to disregard Eggman's vocal commands.
*** Ironically, Dr. Starline himself falls into this when he gets sick of Eggman's shortsightedness regarding the Metal Virus and elects to take matters into his own hands. [[spoiler:Starline's solution is to bring in the Deadly Six to control the Zombots, using the [[RestrainingBolt Cacophonous Conch]] to keep them under his control. However, Starline finds out too late that the conch only works as long as his lungs last, effectively making it useless once he needs to catch his breath, and he didn't have a backup plan in the event he lost it; the minute he lets his guard down, the Deadly Six snatch the conch right out of his hands and hijack the Zombots for their own purposes, which of course just makes the situation even worse. Zavok even [[LampshadeHanging lampshades]] this.]]
--->'''Zavok:''' What was that about a [[IronicEcho "lack of foresight"]]?
*** In Issue 26: [[spoiler:Apparently no one thought that sending Gemerl (a robot) up against a Zeti (who can control machines) was a bad idea. Likewise Cream's insistence on coming and jumping into the portal against his wishes ended up putting her in danger as she didn't have much of a plan other than trying to shame Zeena into giving up.]]

* ''ComicBook/{{Invincible}}'': ''Invincible Universe'' #12 sees the Lizard League transform several members of the Guardians of the Globe into reptilian-people and order them to attack the rest of the team. The transformed Guardians...do ''not'' do that and instead gang up on the League because as Bulletproof points out, their minds were fully intact and the League never bothered to try and develop any means to control them. Notably, this isn't due to a lack of foresight on the leader's part but because of a genuine belief they'd be loyal to him post-transformation.

* ''ComicBook/JohanAndPewitt'' had this happen in the backstory of "The War Of the Seven Fountains". They stumble across an old, abandoned castle in the middle of a wasteland, and that night are met by the ghost of its former king, who explains that the reason the kingdom disintegrated was because of his idiotic use of a wish he had been granted by a local witch as a reward for his wise rule. Unfortunately, while a great ruler in most cases, the king had a love for wine, and the wish happened to be granted during a period where the wine harvest had gone wrong, and there was none to be had for miles. In a spur of the moment, the king wished that the areas seven water springs would produce wine instead of water. You can probably guess why this was a bad idea. When he tried to force the witch to reverse the magic, she instead cursed the springs to dry up completely, leading to the kingdom falling apart and its inhabitants leaving. The king remained behind and died soon after, but was BarredFromTheAfterlife by his ancestors, and wouldn't be allowed to rest until the springs flow again, which Johan and Pewitt decide to help with (with a surprise assistance from TheSmurfs).

* ''Franchise/{{Batman}}''

* In one issue of the ''WesternAnimation/BatmanTheBraveAndTheBold'' comic, ComicBook/{{Nightwing}} leads the ComicBook/{{Robin}}s from other points in time (Jason Todd, [[Comicbook/RobinSeries Tim Drake]], [[ComicBook/Batgirl2009 Stephanie Brown]], Damian Wayne and [[ComicBook/BatmanTheDarkKnightReturns Carrie Kelly]]) to one of Ra's al Ghul's bases in order to use a Lazarus Pit to save Batman's life. When they encounter the League of Assassins, Damian leaps out, demanding that they stand down as is his birthright as an al Ghul. The assassins look at each other, then charge at the Robins. Damian then remembers that he's not born yet.

-->'''Flagg''': When you set out to blackmail the Squad, Senator, didn't you realize you were trying to coerce thugs and killers? Ruthless people. Didn't it ever occur to you that the easiest way of dealing with you was to kill you?
* Comicbook/{{Supergirl}}: Some of her adventures provide good examples:
** In ''Comicbook/RedDaughterOfKrypton'', Supergirl used her heat vision on a blood maelstrom conjured by Atrocitus, and accidentally burned half city down instead of destroying the maelstrom.

--->'''Superior Girl''': That was not my best plan.
** In ''[[Comicbook/Supergirl2005 Supergirl Volume 5]]'' #3 Supergirl decides to fight Comicbook/LexLuthor alone. Quickly she realizes her plan is not a brilliant one.

** In Supergirl Annual #2, ''Comicbook/{{Brainiac}}'' 5 was analyzing how a mystical statue reacted to different kinds of energy, and he accidentally turned it into a kind of super-bomb. He admitted that it was not a very good plan.

** ''Comicbook/KryptonNoMore'', super-villain Protector wants to defeat Superman... so he bursts into the Fortress of Solitude and attacks both Franchise/{{Superman}} and Comicbook/{{Supergirl}}. He gets his butt royally kicked and has to run away at the first opportunity.
** In ''Comicbook/WarWorld'':

** ''ComicBook/ArchieComicsSonicTheHedgehog'':

* ''Franchise/{{Batman}}'' villain Warren "Great White Shark" White successfully pleaded insanity to escape embezzlement charges. He was [[ComicBook/ArkhamAsylumLivingHell sent to Arkham]] and wound up at the mercy of Gotham's worst psychopaths. Oops.

* In the ''Siege'' miniseries of ''ComicBook/SecretWars2015'', Lady Kate Bishop from the 1600s deliberately gets arrested so she can be sent to the wall and join the Watch for adventures. She later gets hit by a magically-induced epiphany, realising that she's a girl with pointy sticks and she's facing terrible armies that scare God-Emperor Doom himself. And said armies are coming for her through a now disappeared wall...
* Doctor Octopus's plan in the ''ComicBook/SpiderMan'' storyline ''ComicBook/{{Ends of the Earth}}''. With the evil doc dying, Doc Ock plans to [[spoiler:flash-fry the Earth, leaving approximately .08 percent of humanity to live on and remember him as the greatest monster that ever lived]]. However, Spidey points out a glaring flaw in this plan: [[spoiler:they'll live. Brain dead, their brains flash-fried, too]]. Doc Ock [[VillainousBreakdown flips]].

Not only does his interference directly result in a CosmicRetcon, but the residual energy left behind by the Super Genesis Wave ends up ripping Sonic's World apart and awakening [[EldritchAbomination Dark Gaia]], leading into a ''VideoGame/SonicUnleashed'' adaptation. With all of this, Eggman admits that his actions were "[[{{Understatement}} a bit hasty]]."

* An issue of ''ComicBook/{{Preacher}}'' has Jesse meeting Johnny Lee Wombat who dreamed his entire life of being an astronaut. He eventually got into the Air Force but as a clerk as he was denied flight training. Johnny finally forged his orders to get accepted into NASA training...and lasted less than twenty-four hours before they kicked him out. How did they find out? Because the reason Johnny was passed over had nothing to do with his intellect or piloting skills but the simple fact he [[DreamCrushingHandicap barely stood five feet tall]]. One look at him in the lineup of average-height pilots and the instructors knew there was no way this guy had gotten through pilot training.

* An issue of ''ComicBook/{{Preacher}}'' has Jesse meeting Johnny Lee Wombat who dreamed his entire life of being an astronaut. He eventually got into the Air Force but as a clerk as his education just didn't match the training. Johnny finally forged his orders to get accepted into NASA training...and lasted less than twenty-four hours before they kicked him out. As it turns out, Johnny failed to consider the fact he was nearly two feet shorter than the height he'd put down on his forged papers and one look at him in a lineup told the instructors there was no way Johnny had gone through flight training.

* In ''ComicBook/SonicTheHedgehogIDW'', this is the FatalFlaw to both Dr. Eggman and Dr. Starline. Eggman is usually lost in his desire to finally defeat Sonic that, when he initiates a plan, he does so haphazardly and just fixes kinks along the way. For Starline, he only thinks things through ''to a point''. He doesn't consider any sort of [[SpannerInTheWorks Spanners in the Works]] and is left scrambling.

* A secret cabal of criminals in Metropolis has a member who's setting fires as part of an insurance scam. He bribes a kid to say Superman did it, claiming it'll be a good distraction. His boss chews him out for honestly thinking anyone in Metropolis is going to believe Superman is going around setting fires for no reason. By trying to make it look that way, the guy has simply ensured that Superman and the fire department realize something is up and start looking for the real arsonist.
** That same guy is killed by an enforcer who drops him from the sky in the middle of Metropolis. The cabal's reporter ally immediately tries to put together a "SUPERMAN MURDERS MAN" front page for ''The Daily Planet''. Perry White's response to her attempt can be summed up as "so Superman, for no reason, kills a low-level thug in broad daylight in the middle of the city? And the only "proof" is eyewitnesses seeing a red blur which could easily be Bizarro, a shapeshifter or a dozen different flying people in costume? And somehow, Superman did all this when he was ''on film'' helping the Justice League fight Starro across the country ''at the same time''?" Needless to say, the story does not see print.
