** ''Pahkitew Island'': Ella seems completely oblivious to how much Sugar despises her (because [[EvilCannotComprehendGood Sugar thinks Ella's sweet personality is a façade like hers]] and wants steal her spotlight).

* In some episodes of ''WesternAnimation/SpongeBobSquarePants'', Plankton is so pathetic that Krabs and [=SpongeBob=] see him as more of an annoyance than a genuine threat.

** There's a weird variation on this in an early episode, in a match between Bill Gates and Michael Flatley. What was the reason for the match? Well, at first, even ''they'' had no idea. (Each admitted they had no grudge against the other.) Right before the fight, however, the Nick and Johnny found out it was due to a clerical error in the scheduling. Still, why not? They simply called it "The Battle of the Clerical Error".
** Played straight in one HalloweenEpisode where an undead Stacy Cornbread came back leading an [[ZombieApocalypse army of zombies]] to get revenge on Debbie Matenopoulos, claiming Debbie had stolen her job. The biggest thing wrong with this was that it wasn't Debbie's fault; she hadn't even appeared on the show until several episodes after Stacy's death and had never even ''mentioned'' her. Still, if Stacy came looking for a fight, she certainly got one; Debbie was only too willing to kill her again.

* ''WesternAnimation/TheVentureBrothers'':

* ''WesternAnimation/StaticShock'': In "The Big Leagues", a crossover with ''WesternAnimation/BatmanTheAnimatedSeries'', Static gets increasingly annoyed that The Joker refuses to acknowledge him as an opponent. Joker keeps ignoring him and even forgets about him at one point, having to be reminded by his henchmen that he exists. When Static, Batman, and Robin are knocked out by a trap, Batman and Robin are captured, but Static is left behind because Joker didn't see any value in him. It is really cathartic for Static when he manages to capture Joker.

* In ''WesternAnimation/FostersHomeForImaginaryFriends'', when Duchess reveals herself to Bloo and talks about her plan to [[NeverSayDie get rid of him]], it takes a while for him to figure out who she is and why she hates him. He's even apologetic when he does.

* In ''WesternAnimation/RockyAndBullwinkle'', the protagonists seem completely unable to recognize the show's ''only recurring villains'', Boris and Natasha. It helps that the villains are spies who deliberately try to stay covert, and they typically only meet the heroes face-to-face in disguise ([[PaperThinDisguise paper-thin]] or otherwise; doesn't matter too much when the heroes wouldn't recognize you if you were wearing no disguise at all.) Rocky occasionally remarks that he recognizes Boris' voice, but that's the closest they ever get to remembering the villains between episodes. This even continues into the movie!

* In ''WesternAnimation/OverTheGardenWall,'' [[ExtravertedNerd Jason Funderberker]] seems unaware that he and [[SociallyAwkwardHero Wirt]] are both interested in [[GirlNextDoor Sara]], or else is really mellow about it.
