* In the ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' episode "A Very Special Mandy", a RealityBreakingParadox is caused by [[PerpetualFrowner Mandy]] smiling. Another episode had something similar caused by Billy getting an A on a test, though it's worth noting that Grim had magically altered Billy's mark, so maybe the scythe had something to do with that one.

** In "[[Recap/PhineasAndFerbLawnGnomeBeachPartyOfTerror Lawn Gnome Beach Party of Terror]]", Linda becomes very concerned when she doesn't receive a call from Candace about the boys' latest activity. And when she calls her, Candance is currently in a romantic state since she's spending time with Jeremy, saying that everything is fine. This convinces Linda to come home immediately.

** "Husky Bobby": Preventing his son Bobby from participating in a fashion show at the mall has the normally safety-conscious driver Hank [[DrivesLikeCrazy driving like an utter madman]] -- speeding through traffic, cutting off other cars, running red lights (presumably), cutting across a roundabout lane, and [[ArsonMurderAndJaywalking filling up on 89 octane gasoline]], stunts he would ''never'' pull in any other situation.

** ''WesternAnimation/Ben10UltimateAlien'': Near the end of Season 1, Kevin absorbs Ben's Ultimatrix energy in a last-ditch effort to stop Aggregor, and promptly [[WithGreatPowerComesGreatInsanity goes]] AxCrazy again. After failing to stop him several times, Ben, known for his ChronicHeroSyndrome and being a WideEyedIdealist, decides outright that Kevin is [[BeyondRedemption too far gone to be saved]] and [[ShootTheDog must be put down]]. While Grandpa Max remarks he'd do the same, he still notes that things must be ''really'' bad if Ben's willing to go that far and not try to reason with him first.
** ''WesternAnimation/Ben10Omniverse'': Ben is [[{{Flanderization}} flanderized]] into an impulsive, clumsy and ego-driven ButtMonkey who barely takes situations seriously anymore. However, when it came to Malware and, to a lesser extent, Vilgax, Ben's flanderization is non-existent. With Vilgax, he's mostly back to being his ''Alien Force-Ultimate Alien Era'' personality of taking things serious when needed. With Malware, Ben is outright terrified and it is not PlayedForLaughs.

*** But PlayedStraight later in the episode where [[CoolOldGuy Iroh]] admits Azula needs to ''go down''. This coming from the man who is the epitome of kindness and patience.

*** To give it some more context, the first time she used bloodbending, the time that it horrified her and drove her to tears, she was forced into a situation where [[SadisticChoice the only choices were "bloodbend" or "let Aang die"]], and used it to save Aang's life. When she uses it again, not only is it completely unnecessary for her to do so, she's using it to ''torture'' someone. It really rams home how far she's slipping in her pursuit of vengeance.
*** Another Katara moment comes when Zuko joins the Gaang. She coldly threatens to kill Zuko if he ever looks like he's about to regress to his old self and harm Aang. Katara ''abhors'' extreme violence and has never brought up the concept of killing before. So it goes to show just how strongly she feels about Zuko and Aang if she's willing to cross that line.

* The first five minutes of ''WesternAnimation/BatmanBeyond'' have Batman [[DentedIron suffering a heart attack in his old age]]... while trying to deal with a thug. When his opponent starts to overpower him, BatmanGrabsAGun. Not only does the thug immediately understand that "Batman pointing a gun at you" is an incredibly bad thing and book it, but this is the incident that makes Bruce realize that he can't keep doing this, and he hangs up the cowl.

* ''WesternAnimation/TheVentureBrothers'': Kano, a member of the old Team Venture, took a vow of silence and is essentially mute in almost all of his appearances. When [[spoiler: the Blue Morpho]] shows up in "Arrears in Science", he utters in complete disbelief, "No. It cannot be."[[labelnote:explanation]]The character in question was an affiliate of Team Venture and has been thought dead for decades, and Kano was the one who had killed him; they were long-time friends and he'd been forced to do it to protect another, which is why he took his vow of silence in the first place.[[/labelnote]]
