The following have their own pages:
Other
- Emmy in Demo has a Compelling Voice that she has no control over; it's always on. She tries to get by without talking at all, which generally she can... unless someone's hassling her and refuses to back off, that is.
- Suntop in ElfQuest has a version of this. Since his power is extreme empathy, he's able to feel the anguish of any elf strong enough to communicate it magically. Even pain from thousands of years into the future. He can't help it, since he's just a child for most of the main plot.
- Mind*** in Empowered can only speak and see using her psychic powers, which makes her unable to lie, because her brother removed her tongue and eyes so she'd be forced to rely on her powers more, and reads the minds of everyone nearby; since most of those people are superheroes and most of them are jerkasses, she can't really handle being in groups for long and spends most of her time on their space station alone, which she hates.
- In Finder, Jaeger's healing factor makes him near impossible to kill, but is so robust he has to get injured regularly to avoid becoming ill.
- In the Hellboy/B.P.R.D. comics, Liz Sherman has a great deal of difficulty controlling her pyrokinetic powers. Some of this is due to the nature of her abilities, but some of it is also due to psychological trauma related to her first manifestation (at age 11, she destroyed her entire family and 30 other people) and the institutionalized upbringing that followed.
- Xadhoom's power in Paperinik New Adventures need to be kept in complete check, otherwise she will either explode with the force of a nova before collapsing in a black hole (or so she says) or (in the earliest moment after she acquired them) dissolve into nothingness (as happened to Zoster when she let him find out how to achieve her powers). Also, they once reacted to her wish to return normal by making her recover her original looks while apparently disappearing, only returning when she got pissed at the villain.
- PS238: Harold Nelson, the "Rainmaker", obtains the metahuman power to intensify or downgrade the metahuman powers of others, leading to Power Incontinence when he turns their power up to maximum level. At one point he forces a superheroine-in-training with Shock and Awe powers to continually fire lightning and makes another who uses the Square-Cube Law to become 'denser' and more powerful to become so dense she's unable to move.
- Queen Bee: Haley often has trouble with controlling her psychokinesis, with results ranging from merely embarrassing to quite destructive. Alexa, who has the same abilities as Haley, is far more skilled with her powers.
- The character whose murder starts off the plot for Rising Stars is physically invulnerable, but that results in him being unable to have any sense of touch at all. He becomes an obese couch potato because without physical sensation, he can't experience any form of physical pleasure except for the taste of food. His murder is carried out when he falls asleep in his chair and he's unable to feel that he's being bound to it by the murderer (who asphyxiates him with a plastic bag).
- Sonic the Hedgehog (Archie Comics):
- When Mina Mongoose first awakened her Super-Speed, she had absolutely no idea how to control it, slamming into things at high speeds. She's forced to ask Sonic for help, though she also uses that time to show off her crush for him, too.
- When Knuckles accidentally awakens his Chaos Force powers following an attack by the Dark Legion that tossed everyone save Knuckles and a captive Julie-Su into another dimension, he ends up glowing green and accidentally unleashing a lot of power. When the echidnas in Abilon find out about this, they attempt to suck his powers out. All he does is blow up the machine and turn the poor sap at the controls into Doctor Finitevus.
- Star Wars Legends: The reborn Emperor in the finale of Dark Empire creates a Force Storm to deal with a Rebel fleet parked in front of his enormous battlewagon Star Destroyer. When he's about to be killed by the Skywalker twins, somehow he loses control over the Force abomination and it begins to consume him and his ship in a titanic conglomeration of power.
- The Magnet in Terra Obscura. By the time the story takes place, he has almost no control over his magnetic powers. However, they're also not nearly as powerful as they once were, so he mostly attracts coins, staples, and other small objects made from ferrous metals, and even then only when he's within arm's reach of them.
