Story Idea (Suggestions Wanted!)

So here's a story idea I've been tossing around in my head for a white: What if someone could magically transport themselves into fictional worlds?

Think of it like the movie Last Action Hero. For those who haven't seen it, it's about a 10 year old kid with a magic movie ticket that accidentally transports him into the Arnold Schwarzenegger action movie he's watching. The villain of the movie-within-a-movie eventually steals the magic ticket and figures out how to leave the movie and go to the "real world", followed by the kid and Arnold's hero character.

Completely off topic, but I always enjoyed this movie. It was a box office disappointment at the time, because people were expecting a real action movie from Arnold, not this parody of his usual action movies. It was ahead of its time in terms of being meta and self-aware of its tropes, but as I said, I always liked it.

But back on topic: My story idea is about a woman who has a ticket like that, or some other way to visit movie, TV, maybe even comic book, or novel worlds, and later return to her "real" world. But instead of just playing along with the plots of these fictional worlds, she decides it would be fun to visit sci-fi and/or fantasy worlds where she can gain superpowers, just see what it's like to fly, lift cars, turn invisible, etc. I'm assuming she'd essentially become a supervillainess in the worlds she visits, not because she's actually evil, but just because she figures it doesn't matter, since it's a fictional world anyway and the people aren't "real", so she can do whatever she wants.

What fictional settings would she visit? What powers would she gain? I've got a few specific ideas, but I'm looking for more suggestions. 

To be clear on what I'm looking for: I'm leaning towards sticking with live action movies and TV, unless someone has a compelling suggestion for cartoons, novels, or comic books to include. The works of fiction she visits should include some relatively easy and straightforward way that she can acquire superpowers within that world. So something as involved as surgery to become the next Bionic Woman would be too much. But "borrowing" the red kryptonite gun to steal Superman's powers in the Ultrawoman episode of Lois and Clark would be obvious. 

One detail I haven't decided is whether superpowers gained in one setting should transfer to the next, when she moves between works of fiction. Obviously, none of them come with her when she returns to her "real world", much like Arnold's character losing his movie mojo when he leaves the movie and goes to the "real world" in Last Action Hero. I'm open to opinions on that.

So if anyone has suggestions for movies, TV show episodes, or anything else my character should visit to gain superpowers, let me know.
