Okay kiddo, let's talk about something really cool called a "fictional crossover." Have you ever read or watched different stories about different characters and wondered what it would be like if they met each other? That's exactly what a crossover is!
Imagine you have a big box of toys, each with their own story and world. One day, you decide to mix them all up and play with them together. That's what it's like when a fictional crossover happens. Different characters from different stories come together into one big adventure.
For example, maybe you've seen the movie "The Avengers." That's a crossover story where characters like Iron Man, Captain America, and Thor all come together to fight against a bad guy. They each have their own movies and comics, but in this one story, they team up.
Another example is in the TV show "Once Upon a Time." It's a story that brings together different fairy tale characters like Snow White, Cinderella, and even some characters from "Frozen." They all live in the same world and their stories sometimes overlap or connect.
So, a fictional crossover is when different characters from different stories come together and have an adventure. It's like a big toy box full of different toys, all playing together!
