History Fanfic / ASparkOfGenius

Official Summary: Xander Harris was never called a genius, but after a different choice of Halloween costumes he is hit with a "spark" of mad genius, the abilities that go with it, and flung into a far different world. Come and enjoy the madness.

** Jenny is now a technomage, and combines binary and computer codes to make a make-shift GreenLanternRing.

* AbsoluteCleavage: When Xander innocently asks [[spoiler: Cat-Woman]] to make herself more comfortable in his hotel room, she pulls down her front zipper and exposes everything down to her nave.

* RealityEnsues:
** Xander uses his portal technology to blast Hawkgirl with arctic water. Xander's banter is cut short when he realizes she's entering the first stages of hypothermia and he quickly teleports her to the Watch Tower's med-bay.
** Xander's attempt to disarm a suicide bomber at Super Speed result in him accidentally tearing the man's arm off.
** After years of constantly handling Kryptonite with his bare hands and even wearing it on his finger as a make-shift ring, Lex Luther ended up getting a brain tumor.

* AlmightyMom: When Lois finds out that all of the annoying things hapening about her all week are due to someone pranking Superman, she tells him to make it stop... or she'll tell his mother. This visibly scares Clark.

* AnyoneCanDie: [[spoiler: Angel, Spike and Drusilla]] end up dying in the first half of the story, with [[spoiler: Angel and Spike]] being killed in the very first chapter by Xander.

* AscendedFanboy: Xander gets sent into the DC universe, where he repeatedly interacts with heros and villains he only read about in comics. Takes care of problems fans have been complaining about for years, rewrites story lines, pranks some of the biggest names in that universe and [[spoiler: ends up sleeping with Zatanna and Cat-woman, as well as kill Lex Luther]].

* ChildProdigy: While sneaking around [[spoiler: Romania]], The Question stumbles across two children whose feet don't even touch the ground while sitting debating about the Dionysian and Apollonian life models, and is shocked to find that such discussions are happening between children and teens all around him.

* DatingCatwoman: Literally in the case of Xander. They seem to get along really well, especially since Xander has a sense of humor. Unlike [[Franchise/{{Batman}} certain other people we could mention.]]

* DoesNotLikeMagic: Xander doesn't like magic, due to his belief that it doesn't like him. It doesn't help his belief when spells malfunction in his presence and an entire race of magical beings try to kill him.
** [[spoiler: Though he does change his mind somewhat when an accidental WardrobeMalfunction spell culminates with Zatanna seducing him]]

* HappilyAdopted: An odd example. Xander admits that he's never met either Agatha Heterodyne or Gilgamesh Wulfenbach, and isn't even naturally their son. Yet they have done more for him than [[AbusiveParents Tony]] or [[ParentalNeglect Jessica]] Harris ever did for him and happily considers them his real mother and father. Enough that he had a portrait of Agatha painted in her honour.

* MustHaveCaffeine: When Xander is able to replicate Agatha's 'perfect coffee', he is able to use it to gain a near total monopoly on the entire coffee industry since no one will drink anything else.

* OnlyMostlyDead: [[spoiler:Xander after fighting the Old One. He does need to take a bath in his modified Lazarus Pit.]]

* RealityEnsues: Xander uses his portal technology to blast Hawkgirl with arctic water. Xander's banter is cut short when he realizes she's entering the first stages of hypothermia and he quickly teleports her to the Watch Tower's med-bay.

* DidIJustSayThatOutLoud: Andrew accidentally admits to wearing tighty-whiteys.
