Enter, the Gremlin

Human!AU, SI-OC. Jade had always been a weird kid, and not in the 'I'm not like the other girls' way. It had kept her from making friends most of her life, so she spent her time practicing karate religiously, being a slut for Bruce Lee movies, and hanging out with her Abuela. Life wasn't perfect, but it wasn't horrible either.

Then the dreams came. Abuela told her it was a sign, and she was right. After dying(?) in the most cliche way possible (Truck-kun spares no one), Jade wakes up in the middle of some festival after falling out of the sky, getting pointed at by some old guy. She assumed she was just dreaming again (or had finally lost it), but it soon becomes apparent that this is reality. A reality where Kung fu Panda characters are human, Po doesn't exist (which is kind of scary in an existential way), and SHE'S the Dragon Warrior.

Yeah, no

But no one listens to Jade when she says she's an Isekai protagonist, so Jade decides that if she has to suffer, everyone else has to suffer with her. Armed with nothing but a black belt in karate, her backpack, movie foreknowledge, the power of God and Anime, and apparently Kung fu trivia knowledge, Jade sets out to fuck shit up, while also making jokes no one understands.

(Or in which, Jade wants to defeat Tai-lung with the power of La Chancla. Shifu is done, Oogway is amused, the Five are smitten, and all movie villains are defeated by accidental seduction tactics. China never stood a chance)
