Did I Even Take a Real Vacation? (Superhero Crossover)

Allie, a miserable art student who knows nothing about Marvel or DC, dies of ALS and is reborn in the Marvel universe. Then she realizes something is off... For example, a certain second princess of Asgard is obedient and well-behaved (?), a certain busty sweetheart is always at her beck and call, a certain famous Iron Man gives her a fortune, and a certain Sorcerer Supreme knows she has a special origin but still treats her with kindness... Allie: ...Meow meow meow?! And then Hydra sees her and wails in despair, voluntarily offering up the organization's top male model. The Dark Elves (We were just passing through!) see her and drop to their knees, presenting the Aether and their spaceship as tribute... Allie... Meow meow meow?! After the Marvel, DC, and X-Men worlds merge, things develop in an increasingly bizarre direction. The Joker never steps outside Arkham, while Batman cordially invites her to stay in Gotham; Metropolis thrives in harmony, and a spaceship sinks to the bottom of the sea with its kryptonite; Apocalypse of the X-Men digs right through a pyramid, while Xavier's School and the Brotherhood scramble to recruit her, eventually coming to blows... Allie: ...Meow meow meow?! Allie (asking the System): Are you some kind of ridiculous Mary Sue System? The System giggles. Much later, after finally recovering her saved progress from the instance, Allie says: System, I never want to see your damn face again! P.S. Allie really is a big shot, but she's completely sealed away at the beginning. P.P.S. The Allie in the instances is incomplete, so she'll act in all sorts of strange ways.
