In which a twist in time reverses the familiar roles. Now Jinx is the hero and Kid Flash the villain. Leave behind reality and all preconceived notions and journey...
Down the Rabbit Hole is a Teen Titans fanfic by lizzpercush. It ponders the question of what would it be like if Jinx was a Titan and Kid Flash was an agent of the HIVE. The story provides a lot of backstory to Jinx, following her from 10 years old and thus before the show begins and onward through the fifth season. It currently has 83 chapters of irregular length.It can be read here.
Beware the Silly Ones/Crouching Moron, Hidden Badass: He may be charming, friendly and have an enormous crush on his so-called "arch-nemesis," but Kid also orchestrated a successful jailbreak of the Jump City prison fairly easily and was for the longest time the only member of the Hive 5 that the Teen Titans couldn't capture or track.
Mumbo Jumbo manages to make freeze-tag, hide and seek and truth and dare frightening. Think about that.
Brilliant, but Lazy: Kid is actually a rather competent thief and speedster and rather intelligent... however he hates the HIVE Academy and Brother Blood and only participates in the former because he has to.
Brought Down to Normal: Mumbo Jumbo captures Jinx and strips her of most of her powers. When she starts doing too well on one of his imposed challenges, he kidnaps Kid and does the same to him to slow her down. Also, See-More manages to slip a good luck amulet around Jinx's neck which cancels out her hex powers during one of her fights with the Hive 5.
Brought Down to Badass: It doesn't stop her. Even with the amulet, Jinx beats the crap out of the 5 before they manage to catch her and that's only because they got lucky.
Dark and Troubled Past: Jinx's parents are dead and her older sister died in a car accident. Kid's father ran out on him and his mother is very ill. It's also the only reason Brother Blood and eventually See-More can exert any sort of control over him.
Dreaming of Things to Come: Jinx once tried to look into the future. Bad idea. She uses drawing to make sense of what she remembers whenever it comes to her. So far, she's seen Terra, See-More and Kid.
Equivalent Exchange: To get Kid to leave her alone when she first comes to Jump City, Jinx gives him her rose pendant so that he will pass him HIVE assignment and leave her alone and so that Jinx does NOT have to part with any of the incredibly powerful magical artifacts on her person and cause the end of the world. However because powerful artifacts were on the line, it supercharges the exchange of an already priceless if harmless memento for safe passage through the city. Unfortunately for Kid, safe passage isn't payment enough so he becomes a Cosmic Plaything until Jinx comes back to Jump to complete the exchange.
Even Evil Has Loved Ones: Kid, who loves his mother dearly. This eventually extends to Jinx herself, causing him to defect.
I Know Your True Name: In exchange for her rose pendant and her various charms protecting her on her one day out, Jinx takes Kid's name as payment and also to end his 2 year string of bad luck. He's impressed.
Platonic Life Partners: Robin and Jinx meet as children at the behest of Zatanna, and despite the bickering and Batman's apprehension, get on like a house on fire, with Jinx even calling Robin her best friend. Kid suspects Jinx may have had a crush on Robin but then he would.
Psychic Link: After completing her equivalent exchange with Kid, Jinx slaps a tracking hex on him so she can find him no matter where he is across dimension, space and time or what he looks like. He's overjoyed.
