** When Daine's human family is killed, she loses her sense of self and runs with a pack of wolves to seek {{Revenge}}, soon naked and RunningOnAllFours and barely remembering how to use a knife. Eventually she recovered but feared the "madness"; even when she found a teacher, she found herself slipping whenever she worked magic involving pack or herd animals, until he helped her to keep her self separate from her magic.
** Another of her problems is that animals within her radius (a mile and a half in the first book, ''ten miles'' in the second) will all rush to her aid and attack anyone who's made her scared or angry, or otherwise act according to her desires, without her conscious input. They will kill themselves in doing so, and she feels their pain and deaths, but if she commands them not to attack they struggle against her control, so that she has to constantly keep them at bay mentally. If they ''do'' attack, Daine can pass out instinctively healing them. This is ParanoiaFuel in a

** She's mastered her powers by ''Emperor Mage''

** Mages in general in the series have minor ''Harry Potter''-style leakage until they learn to control it. The worst affected character is Zhegorz, a man who was assumed to be plain old insane for having visions and hearing voices and was locked up in a BedlamHouse until he really did develop paranoid schizophrenia or something like it.

* ''Literature/{{Tempest}}'': While the titular half-mermaid is staying on land in ''Tempest Unleashed'', her worries over her injured brother and anger towards [[BigBad Tiamat]] for hurting him cause her WeatherManipulation powers to rise out of control. She runs to a deserted stretch of beach so she won't hurt anyone, but that isn't enough, because all the magic she's pouring into the ocean creates a tsunami that threatens to destroy the neighborhood. She manages to channel all her magic into a piece of sea glass, which causes the tsunami to dissipate.

** In ''Brightly Burning'', Lavan Firestorm's gift of Firestarting was provoked into action by bullies at the Merchant's School. He can't control it himself. His Companion [[spoiler:and lifebond]], Kalira, controls his power. [[spoiler:When Kalira is killed in the final battle with Karse, Lavan has neither the means nor the desire to control his gift further. He incinerates the entire region, including the Karsite army, the surrounding forest and grounds, and himself.]]
** This can be an issue for many Gifted until they are taught how to control themselves; in the Last Herald Mage trilogy, [[spoiler:Vanyel Ashkevron]] needs to be ''removed from the city for everyone's safety'' after suddenly and traumatically developing his strong abilities, and in the Arrows trilogy [[spoiler:Talia]] loses control of her mental powers even after she's supposedly been taught, because of some misunderstandings regarding her training.

** Canary, who has the ability to make people suggestible through her songs, once told her ex to "go fuck himself" without realizing she was affecting him. [[ExactWords He did]]. Fatally.

* This is part of Galadriel Higgins's BlessedWithSuck status in ''TheScholomance''. If she ever tries to cast a spell without enough mana ready to hand, her power will automagically rip the life from everything around her to make up the difference.
