History Fanfic / IrreversibleDamage

* RitualMagic: Susan uses a satanic ritual to [[spoiler:bring Manny back to life]]. Greg overhears this conservation, but doesn't mention it to Frank until later because he doesn't know how he'll react.

* SecondLawOfGenderBending: Following some initial panic attacks, most characters take their transformations very much in stride. In particular, Greg/Greta mainly just cares about how she can use her new situation to gain popularity at school, but eventually decides that she likes being a girl and that she probably wouldn't bother using an antidote even if it existed. Among other characters, "Rowlette" quickly accepts being a girl and promptly starts dating Bryce, Tyson happily starts having sex with the other guys, and Greg's Uncle Gary is elated at the opportunity for advancement at his job as an adult entertainer.

''Irreversible Damage'' is a ''Literature/DiaryOfAWimpyKid'' fanfic (or LLB[[note]]Look-Like Book[[/note]]) written by [[https://www.reddit.com/user/IcyOpportunity9/ IcyOpportunity9]] of ''[[Fanfic/TheYogurtExtendedUniverse Yogurt Extended Universe]]'' fame.

* ArrangedMarriage: Mr. and Mrs. Jefferson's marriage was essentially this. Mrs. Jefferson had originally been dating Greg's father when they were in school, but their parents forced her to break up with him and marry her current husband, despite him being ten years older than her, because Greg's father wasn't well-off enough for their liking.

* AttractiveBentGender: Once Greg realizes that he can use his new female form to get guys to do what he wants, he starts to put effort into his appearance and manages to make himself look very attractive. The inverse of this is parodied with Rowley, who looks precisely the same as he used to but with longer hair.
* BlackComedy: Greg find a potion lying on Chirag's floor that makes people endlessly dance until they die of exhaustion. It pops up frequently in the fanfic, but serves a major role in the B-plot.

* ComedicSociopathy: Greg displays his usual selfish streak, lack of perspective, and tendency to view everything solely in terms of how it personally conveniences or inconveniences him. However, unlike in canon where this applies just to the minor troubles and actions of a middle school kid, in this story his casual lack of interest in the consequences of his actions is applied to things like [[spoiler:turning Chirag invisible and then losing track of him, forcefully turning Rowley into a girl and then ditching him mid-panic attack, and magically compelling multiple people, including his own brother, to dance until they die of exhaustion]].

* UnusuallyUninterestingSight: Most people are far less put out by potions' various effects than one might assume. The various {{Gender Bender}}s go almost entirely unquestioned, nobody pays any mind to the people compelled to dance constantly until they start dying of exhaustion, and [[spoiler:Manny dying gets no emotional reaction out of anybody but Susan]]. Likewise, when [[spoiler:Greg and Rodrick come across their mother and aunt talking about using necromancy to resurrect Manny, Greg's only reaction is annoyance at Manny still being their mom's favorite child]].

* AdaptationExpansion: Frank explains the backstory of Susan and Frank's relationship, specifically focusing on Uncle Larry, who is [[spoiler:Susan's former date and presumed true father of Manny]].
* AdaptationRelationshipOverhaul: In canon, there's no particular connection between the Heffley and Jefferson parents. In the story, [[spoiler:The now-Mrs. Jefferson used to date Frank Heffley during high school, and the two never fully lost their feelings for one another]].

* RitualMagic: Susan uses a satanic ritual to [[spoiler:bring Manny back to life]]. Greg overhears this conservation, and tries not to spoil it to others.

* AdaptationExpansion: Dad explains the backstory of Mum and Dad's relationship, specifically focusing on Uncle Larry, who is [[spoiler:Mom's former date and presumed true father of Manny]].

* RitualMagic: Mom uses a satanic ritual to [[spoiler:bring Manny back to life]]. Greg overhears this conservation, and tries not to spoil it to others.

* UnusuallyUninterestingSight: Most people are far less put out by potions' various effects than one might assume. The various {{Gender Bender}}s go entirely unquestioned, nobody pays any mind to the people compelled to dance constantly until they start dying of exhaustion, and [[spoiler:Manny dying gets no emotional reaction out of anybody but Susan]]. Likewise, when [[spoiler:Greg and Rodrick come across their mother and aunt talking about using necromancy to resurrect Manny, Greg's only reaction is annoyance at Manny still being their mom's favorite child]].

* FailedASpotCheck: Chirag's father mistakes post-GenderBender Greg for his mother, despite his still being at middle school age.

* InferioritySuperiorityComplex: To protect his/her identity, "Greta" instead claims that she recently got transferred to Westmore Middle School.

* KarmaHoudini: Both Greg and Chirag spend the story causing chaos and mayhem, which in Greg's case includes causing numerous people to drink the dancing potion despite knowing full well that they'll dance until they die of exhaustion, [[spoiler:smothering Rowley with a pillow, and causing Manny to have a fatal allergic reaction]]. Neither gets any consequence for this.

* ArrangedMarriage: Mr. and Mrs. Jefferson's marriage was essentially this. Mrs. Jefferson had originally been dating Greg's father when they were in school, but their parents forced her to break up with him and marry her current husband, despite his being ten years older than her, because Greg's father wasn't well-off enough for their liking.

* BlackComedy: Greg find a potion lying on Chirag's floor that makes people endlessly dance a "dab" until they die of exhaustion. It pops up frequently in the fanfic, but serves a major role in the B-plot.

The story follows Greg’s purchase of three magic potions from a shady comic book ad. While the first two potions fail to impress Greg, he is surprised to discover that the third potion is able to reverse the gender of the drinker. Greg decides to use it to fix problems with his school, which goes well until Greg [[OhCrap finds himself drinking the “gender bender” potion]]. It all goes downhill from there.

* AdaptationExpansion: Dad explains the backstory of Mum and Dad’s relationship, specifically focusing on Uncle Larry, who is [[spoiler:Mom’s former date and presumed true father of Manny]].
* BlackComedy: Greg find a potion lying on Chirag’s floor that makes people endlessly dance a “dab” til they’re dead. It pops up frequently in the fanfic, but serves a major role in the B-plot.
* GroinAttack: [[spoiler: Greg kicks Christopher in between his nutsack during the end of their date because the latter wasn’t careful to not blurt out about how easy it was for girls to get pregnant by Tyson. It’s implied that after this incident, Christopher won’t have an easy time to impregnate other girls. This isn’t the only reason why he kicked him in the nuts, though. Greg is told by his dad to not do it to other guys but since he drank the genderswap potion by accident, he doesn’t think that rule applies to him anymore. There were also other guys he thinks deserves it.]]
* InferioritySuperiorityComplex: To protect his/her identity, “Greta” instead claims that she recently got transferred to Westmore Middle School.
* LazilyGenderFlippedName: Greg changes his name to “Greta”, and Rowley changes his name to “Rowlette” after being turned into girls.

The fanfic has an on-going pseudo-sequel, ''All Because of Uncle Gary'', best described as an AlternateContinuity of events during ''The Third Wheel'' and ''Hard Luck'' if Rodrick and Uncle Gary had accidentally turned Greg into a girl via a failed satanic ritual.
