* ''Series/LegendOfTheSeeker'': Zedd, as {{lampshade|Hanging}}d by Flynn, who says them seem inconsistent. There are many times when turning invisible or just burning an enemy would be very useful, but he doesn't.

* Over on the TV side of the Franchise/MarvelCinematicUniverse

* ''Series/WandaVision'': Vision and Darcy are constantly delayed when trying to return to Westview in the funnel cake van. Subverted when Vision has a moment of clarity that allows him to throw off the effects of the Westview hex and remembers that ''he can fly''. He promptly takes off, phasing through the roof of the van leaving the contrived traffic problems behind.

* In an episode of ''Series/{{Frasier}}'', Daphne has a fight with Martin's girlfriend Sherry and storms out of Frasier's apartment. She goes to Niles' place and asks if she can stay the night, which he eagerly agrees to, but Daphne then discovers that she left some medication behind. Niles tries to sneak in and get it, but he gets caught resulting in Daphne and Sherry talking things over and making up. Frasier tells a despondent Niles that he knew taking advantage of Daphne when she was vulnerable was wrong and that's why he snuck in and let himself get caught. Niles says that he had no choice but to try and get Daphne's medication but Frasier replies "You're a doctor. Why didn't you just write her a new prescription?"

** [[TheEmpath Deanna Troi's]] abilities vary wildly over the course of the show. In some episodes she can easily sense beings on other ships or on a planet's surface while she is on the ''Enterprise'' in orbit. But when this kind of power would [[StoryBreakerPower eliminate suspense from the plot]], she mysteriously becomes unable to sense people she knows very well, even if they are relatively close by.

** On a less serious note, the levitation power that Whitelighters possess (i.e. the power that gets Leo caught out as a Whitelighter by Phoebe in the first place) is forgotten on several occasions where it could be potentially useful. It is justified that Paige can't use it yet; she's not a full Whitelighter, but Leo has no such excuse [[spoiler:until he loses his powers, that is]]. In a particularly bad example, Leo offers to get a broom to switch off the smoke detecter despite having used his levitation power to do the job in a previous episode, forcing Piper to blow it up.

** ''Series/PowerRangersWildForce'' Ransik and Nadira the reformed main villains from ''Series/PowerRangersTimeForce'' return but apart from the flashback scene that shows the creation of the mut-orgs their powers from ''Series/PowerRangersTimeForce'' don't return and they are not even mentioned.

** From the "Super" half of ''Series/PowerRangersMegaforce'', the rangers gain an entirely new set of powers at the start of the season. The problem, however, is that the rangers still have their regular Megaforce powers - it would be one thing if they established that the new villains were stronger than the Megaforce powers, hence the need to stay with the Super Megaforce power, the Megaforce powers evolved into the Super Megaforce powers like the Zeo Crystal[[note]]admittedly, that would require the explanation of the suits changing from an angel theme to a pirate theme, but it would be better than nothing[[/note]] or if the Megaforce powers had been ''destroyed'' like in ''Mighty Morphin'' or at the end of the aforementioned ''Turbo'', but they don't even bother doing that. This is largely due to the decision to adapt both ''Series/TensouSentaiGoseiger'' and ''Series/KaizokuSentaiGokaiger'', and all footage from the former hadn't been used up. The show does somewhat justify this in the later half, when they adapt the final part of ''Goseiger'' mid-way through the second half of ''Super Megaforce''[[labelnote:explanation]]''Megaforce'', which was the adaptation of ''Goseiger'', adapted the majority of the plot of it's source material; however, the finale, where Brajira/[[DubNameChange Vrak]] is dealt with and the fate of [[SixthRanger Gosei Knight/Robo Knight]] is resolved, was not adapted[[/labelnote]], but instead of having the final battle with Vrak result in the destruction of their powers, or them giving their powers up to create a second team, after Vrak is dealt with, the Megaforce powers remain for no good reason other than the fact that they only had 3 episodes left of the series.

** Also from Turbo, the episode "Passing the Torch Part I" has the Rangers being overwhelmed by monster attacks, and them seemingly forgetting that they're Power Rangers for most of the episode, fighting them all unmorphed, despite being clearly outmatched.

** Also from Turbo, the episode "Passing the Torch Part I" has the Rangers being overwhelmed by monsters attacks, with only Justin making any effort to actually use his Ranger Powers during this onslaught.

** From Season 1 of ''Series/MightyMorphin'', after Tommy has lost his Green Ranger powers because of Rita's candle, it doesn't occur to her to have Finster recreate one of his monsters that the five original Rangers--Jason, Zack, Billy, Trini, and Kimberly--couldn't have defeated without Tommy's help, such as Spidertron, his Frankenstein monster, Babe Ruthless, or the Samurai Fan Man. Likewise, in Season 2, after Lord Zedd's monster Turbanshell has stolen what is left of Tommy's powers after he has temporarily regained them (as of the 2-part episode "Return of an Old Friend" in season 1), it doesn't occur to him to have Finster recreate one of his more recent monsters that the Rangers couldn't have defeated without Tommy's help, such as the Lizzinator, Soccerdillo, or Dramole.

Such monsters included the Samurai Fan Man, Lizzinator, Soccerdillo, Dramole, and Finster's Frankenstein monster.

** [[Series/TheFlash2014 Barry Allen]] ''constantly'' forgets he's the Fastest Man Alive. Numerous times, a villain is able to temporarily blindside Barry, using the distraction to run away. Barry never thinks to do a lap of the building and find them. Even if they jumped straight into a car and sped off, Barry can ''break the sound barrier'' from a standing start, so a quick jaunt around the block could be accomplished before the villain even had their seatbelt on.
