[Western Crossover] I'm the Joker's Little Sister

I’m in my final year of high school, so I’m writing this alongside the Savior story after the college entrance exams. (Very loudly!) (I hope I can pull it off. Go me!)

Anlita Xavier has no memories from before she turned eight.

But that doesn’t stop her and her adoptive father, Charles Xavier, from loving each other dearly.

Then one day, a weirdo in a skintight suit sneaks into her room and tells her, “You have a biological older brother, but he’s in the DC universe.”

Who the heck knows what DC is? Anlita calmly calls Hank over and has him toss the creep out of the school.

One day, she goes to the teleportation point the weirdo mentioned. The world spins around her, and she finds herself in a gloomy city, facing a green-haired clown who has painted his face all over and is laughing hysterically at her.

Anlita: “...”

Only later does Anlita learn that the Arkham VIP who keeps kidnapping her, threatening Batman, blowing up Gotham, and is the ultimate masochist is her own utterly unbelievable biological older brother.

Anlita: “Heh.”

The Joker: Why do I suddenly feel a chill down my back?

Not incest. Pairing undecided.

Content warning: Side pairings: Erik/Charles, Thor/Loki

Updates whenever I can =￣ω￣=

Author’s headcanon: Before he became the Joker, he was very fond of his little sister. So when he learns that Anlita is his sister, he won’t hurt her anymore.

Anlita is genuinely strong-minded. She dares to accept the Joker as her biological older brother and won’t break down or run away.

Waaah, I’m sorry. I’m a student, so I don’t have enough time to write two stories at once. I’m taking a break for now, but I’ll be back later.

Theme: Breaking the rules of the world
