* In the Creator/MarvelComics CrisisCrossover VillainTeamUp ''ComicBook/ActsOfVengeance'', Loki makes the incredibly dumb choice to recruit both an [[Characters/MarvelComicsRedSkull unrepentant Nazi]] and a [[Characters/MarvelComicsMagneto Holocaust Survivor]] into his inner circle. The Asgardian was the only one who was surprised when Magneto attacked the Skull instead of any of the actual heroes, ultimately leaving Red Skull BuriedAlive in an [[SealedRoomInTheMiddleOfNowhere abandoned fallout shelter]]. And Loki is supposed to be one of the ''smart'' Asgardians.

*** [[spoiler: The entire deal goes back to the end of the infamous storyline ''ComicBook/JusticeLeagueOfAmericaTowerOfBabel'', where we find out that Superman confronted Batman and pointed out the glaring flaw in his "let the JLA handle him" failsafe - how are they going to stop a man who is just that paranoid? Sadly, even Superman didn't recognize the fact that maybe Bats would realize Superman was right]].

** In ''[[ComicBook/Supergirl2005 Supergirl Volume 5]]'' #3 Supergirl decides to fight Comicbook/LexLuthor alone. Quickly she realizes her plan is not a brilliant one.

* ''ComicBook/{{Superman}}'': The Pre-Crisis origin of Bizarro is a result of Lex Luthor using a duplicator ray to make a duplicate of Superman, assuming that the resulting Bizarro would want to help him. Instead, Bizarro teams up with Superman and arrest Luthor. He still ended up causing trouble for Superman shortly afterwards, not that it helped Luthor, though.

* In ''ComicBook/{{Superior}}'', demon Omron tricks young Simon into trading away his soul to become the super hero Superior. With time winding down before his deadline to avoid being thrown into the depths of Hell, Omron celebrates his first soul...until friend Madeline points out the problem: Omron has made Superior into a being who is, for all intents and purposes, immortal. And if Superior can never die...then how is Omron going to collect his soul?
* ''Franchise/{{Superman}}'':
** ''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.

* ''ComicBook/XMen'': Strongly implied as the main problem for Fabian Cortez, a traditional X-Men villain, in his 2020s stories. In 30 years of stories, Fabian has developed a modus operandi: He convinces people that he is a useful ally for them, then works to undermine them. The end result of having used this plan far too often: nobody trusts him, nobody likes him, and he is treated with cold indifference when trying to suggest plans. While talking to Nightcrawler, Fabian reveals that many of his plans were misguided attempts to prove his own importance, or misguided attempts to get people to like him. Not only have these attempts backfired to a great degree, Nightcrawler points out that Fabian has grown to disdain himself due to his methods.

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

* In one issue of the ''WesternAnimation/BatmanTheBraveAndTheBold'' comic, ComicBook/{{Nightwing}} leads the ComicBook/{{Robin}}s from other points in time (Jason Todd, Tim Drake, Stephanie Brown, Damian Wayne and 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.

* The undoing of many ''ComicBook/{{Diabolik}}'' one-shot villains, as their plans tend to have a flaw that [[MagnificentBastard Diabolik]] or [[SympatheticInspectorAntagonist Ginko]] can exploit. Case in point, the copycat who recycled Diabolik's plans and had them executed by lesser thieves: while he had planned for Diabolik to track him down planning to kill him he completely forgot about his accomplice and lover Eva Kant (who, while he was gloating he was about to get rid of Diabolik and take his place, had snuck behind him with some poisoned needles), or that Diabolik [[NeverRecycleYourSchemes rarely reuses old plans]] because next time Ginko will be ready (he had got away so far because the targets weren't worth of Diabolik, but after establishing the existence of the copycat Ginko was preparing for him).

* In ''ComicBook/TheMightyThor'' storyline ''ComicBook/TheBalladOfBetaRayBill'', Mjolnir's worthiness enchantment ended up becoming this -- for the longest time, Mjolnir had the worthiness enchantment attached as a way to temper and humble Thor as punishment for his arrogant actions. Never once had Odin the Allfather ever consider that there would be someone else just as worthy, as the alien Beta Ray Bill would soon prove to be when he randomly hit the carrying stick that disguised the hammer against the wall in frustration and transformed into Thor. When Odin brings Bill to Asgard, he's shocked by what he sees.

* At the end of the first arc of ''ComicBook/ThePowerpuffGIRLS'' by IDW Publishing, Mojo Jojo plans to hide in a space pod for several months until he's ready to return to Townsville. He then realizes that he forgot to install a bathroom, which leads to him actually saying that he didn't think this through.

* In ''ComicBook/{{Runaways}}'', during their first battle against Excelsior, Chase Stein decides to create a distraction by attacking with the Leapfrog's lasers...which quickly drains the Leapfrog's batteries, forcing the Runaways to flee with their highly distinctive vehicle fully exposed (because without battery power, they can't activate the vehicle's stealth mode) making it easy for Excelsior to track them down. Later in the same arc, Chase makes a similar mistake by ripping out one of the lasers to use it against a villain. Since the laser is no longer hooked up a power source...

** Doctor Octopus' plan in the 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]].

* Used in a multipart story by Franchise/ArchieComics, starring Veronica Lodge, Betty Cooper, and Cheryl Blossom. One of Veronica's schemes backfires on her, and ruins her own social life. Veronica uses doctored photos to try to ruin Cheryl's reputation, driving the girl to tears. Veronica fails to figure that she looks like a villain to her peers. Veronica then rejects Betty's efforts to serve as her conscience, and unwittingly alienates her best friend. Betty and Cheryl befriend each other (bonding over shared grief), and spend most of their time together. Archie has no interest in dating Veronica, as he is also angry with her behavior. After more than a month of being friendless and dateless, Veronica tries to find a way to regain Betty's friendship.
* Strongly implied as the main problem for Fabian Cortez, a traditional X-Men villain, in his 2020s stories. In 30 years of stories, Fabian has developed a modus operandi: He convinces people that he is a useful ally for them, then works to undermine them.

Not only have these attempts backfired to a great degree, Nightcrawler points out that Fabian has grown to disdain himself due to his methods.

* In the comic adaptation of ''Literature/TheDestroyer'', one story centered on a prototype nuclear pistol designed for the Army; basically a handheld small warhead launcher. The developers boasted a mighty five-kilometer blast radius... and less than a ''two-kilometer'' range. It wasn't until they tried to pitch it to a group of officers that someone pointed out the big problem.
