Up for Grabs, Needs a Better Description (I just want to add this one, but the way it's written, I can't seem to keep it from sounding like Power Incontinence, which it isn't) Although this looks like Power Incontinence, the difference is that this is not necessarily a lack of control of their power. Conscious control, that is. It's like this. When you learn to control your powers, you can get a grip on how to not make them hurt others while focusing. The problem isn't control of one's powers. The problem is the powers themselves, or rather the unconscious portions of having powers. Maybe it is just that their Power Levels are so much higher than those around them, maybe it's the nature of their abilities to act on emotions (making it very dangerous to be near them during issues like depression), or maybe they had a bad dream that is messing with people without their intending it. Simply standing near the Battle Aura of the person may be enough for the passerby to develop a Psychic Nosebleed. Effectively, this is With Great Power Comes Great Insanity only for everyone around you, among other effects, typically based around the user. See also Fisher King for the Reality Warper version of this. The term is based on the Dungeons & Dragons 5th Edition Monster Manual, which offers particularly strong creatures passive abilities known as Regional Effects. Such powers can extend beyond their location and may even persist after their death (for awhile, anyway). It was originally known as Psychic Fallout, because of the tendency for telepathic characters to have this trait far more often than others, and for it to resemble nuclear fallout.
- In Harry Potter, all young witches and wizards have little control over their latent magic, and moments of high emotional distress can cause it to be released completely beyond control. Lord Voldemort, however, inverts this trope by finding a way to weaponize this latent magic at a young age to instill fear among the other children at his orphanage, though he still lacked a fine control over it and often would result in his "pranks" going too far.
- Doctor Who: One of the books follows the Doctor as he enters a cruise that is also a mystery convention full of Expies of various famous mystery characters (and as is usual of the genre, all of a sudden people start getting killed). The twist at the end is that the Miss Marple Expy has psionic powers that she never knew about, and has constantly subconsciously sent out a signal that brainwashed people near her to commit elaborate murders so she could solve them.
- The term is based on the Dungeons & Dragons 5th Edition Monster Manual. These abilities were usually appropriate to the monster, although some were fairly strange (brass dragons apparently can make tracks appear which lead to shelter and water, and away from where the dragon is).
- Zimmy in Gunnerkrigg Court has the ability to cause vivid hallucinations as a persistent aura. This is usually suppressed by Gamma, and Zimmy can do pretty cool stuff when she actively uses her power.
- Jean Grey in some of the X-Men series, can sometimes cause issues in those around her, particularly when she becomes stronger, or when she has serious nightmares.
- Flipside seems to have some sense that powerful mages can literally affect the minds of others.
- In Justice League, Ace has powers that can alter reality around her, and if out of control, they can cause serious psychological damage to those around her (such has, tragically, her parents).. CADMUS takes her into their care and teaches her how to gain some semblance of control over those powers in the name of keeping her as a potential weapon to turn against the Justice League, but this only causes her to become bitter and leads to her nearly permanently altering reality mere hours before her death.
- In one episode of Teen Titans, Starfire and Raven find that their minds have been forced into the other's bodies, complete with powers. Starfire, emotive and full of expression, inadvertently causes all sorts of mayhem around the two of them because Raven's powers stem from her emotions, and letting them run wild means that they will cause several problems when not reined in.
