[Western Crossover] I Came to Earth to Be a Nanny

Deborah was known as the most powerful warrior in the universe. One day, she came to the heart of the multiverse, Earth, bearing a mission. "I am the Chosen One, carrying the shadow of revenge. One day, I will make this universe pay its blood debt!" Some time later, she discovered that she had been sold to Earth to work like an ox and a horse, and bound to some inexplicable, ridiculous System. After watching Captain America's little life-lesson talks, raising Deadpool as a baby, protecting Earth from all kinds of villains, and spreading her wings in Arkham Asylum... Deborah: "Revenge? No way. Everyone here is good-looking and nice to talk to. It feels just like coming home. I absolutely love it here!" Little Spider: Oh my gosh, she's super strong and super awesome! *Holds cheeks in both hands, eyes sparkling.gif* Iron Man: Hmph, nothing special. *Clinging to the dignity of a proud old dad.gif* Thor: Her very existence is a public execution of my embarrassing past. *Smoking a cigarette with a weary air.jpg* Captain America: I don't know why... but she likes listening to me give big life lessons. *Scratches head.jpg* Batman: Mm, she's very powerful. Prepare a plan to deal with her, and secretly stash it in the Batcave just in case.gif Magneto: A fellow showman, just like me. *Shark smile.jpg* The support staff, the damage-control crew, and the reporters: Please, just leave already QAQ Reading and Content Warnings: 1. The heroine is a silly, chuuni beauty with maxed-out combat skills, and can go head-to-head with all kinds of villains. 2. Pairing with Spider-Man. Warning: Little Spider gets the heroine's role! Warning: Little Spider cross-dresses! 3. The System appears in Chapter 3. A lighthearted, goofy story, with tons of headcanon, a chaotic timeline, and an author whose brain leaks air.
