Catalyst

Welcome to Xavier University, where superheroes, mutants, vigilantes, and the occasional extraterrestrial royalty are all trying to survive college life. You're the newest transfer student—and somehow, the biggest mystery on campus. Neither Cerebro nor the Batcomputer can identify what you are, where your abilities come from, or why you've suddenly appeared on everyone's radar. Your roommate is an alien princess, your hallway has a teleporting blue mutant who bamfs through the walls at 2 a.m., and the Danger Room apparently doubles as the hottest party venue on campus. Everyone wants to know your secret. Everyone wants you on their side. And you? You're just trying to survive the semester.

Mutants are vanishing without a trace, and the X-Men's investigation leads to a secret laboratory conducting forbidden experiments on the X-gene. When you're discovered among the facility's survivors, your rescue raises more questions than answers. Now under the protection of Xavier's Institute, you're drawn into a dangerous conspiracy involving stolen powers, buried secrets, and a project that may have been built around you.

A pure, sheltered daughter of a virtuous district attorney is systematically stripped of her freedom and forced to become the hidden, entirely submissive mistress of New York’s most ruthless underworld heir, trapped in an ultra-luxurious gilded cage where his suffocating, sadistically obsessive love and ravenous physical possession are the only terrifying things keeping her family alive.

A Jujutsu Kaisen forbidden romance: you were Ryomen Sukuna's concubine in the Heian era, and now that Yuji Itadori has swallowed his finger, the King of Curses has finally found you again.

In this X-Men AU, Wade Wilson and Logan's daughter stores every hit she takes until she chooses where it lands.

When Lady Mai sweeps back into the palace wearing the crimson that was supposed to be yours, the whisper finds you faster than your dignity: the treaty bride, the placeholder, the foreign girl who could never fill the silhouette of the one who came before. But your husband will not let a ghost in red unravel what he has branded as sovereign and beloved, and Zuko will set the very air ablaze with a devotion so public, so possessive, that the old flame will have no choice but to bow. He married peace, but tonight he will show the world he would burn it all down just to keep you.

In an ABO world of packs and hierarchy, a sheltered omega is handed over to a ruthless alpha heir to settle her family's debt.
