Megamind post-reform; he could solve all the world’s problems that can be solved technologically. And make a fortune doing it (wonder why that never occurred to him).
My first thought was Jessica Rabbit too, but those proportions would just be…offf.
Clinton Tyree, aka Skink. Maybe convince him to work in NY for a little bit.
I get that you don’t believe in God or the resurrection of Jesus; but it’s pretty well established, and believed among modern scholars that Jesus did exist.
The first fictional person I thought of was Eddie Morra, the character played by Bradley Cooper in Limitless. But that would only be worth it if he would give me some of his magic pills. 
Buffy
I’m torn between “Sabrina Duncan” as played by Kate Jackson in the original “Charlie’s Angels” TV series, and Wonder Woman as embodied (!?!) by Lynda Carter. Both for purely selfish reasons, of course…
God …zilla.
I’ve had to rethink some of my first choices: How could I choose Modesty Blaise without Willie Garvin? Clark Savage Jr. without his Fabulous Five? Steed without King(or vice versa)?
In the world we have now Woodrow Wilson Smith would just lay low, and Sherlock Holmes would be way out of his league.
I choose Swamp Thing.
Frankenstein’s monster. Obviously.
In a world without vampires and demons? What would she do?
What makes you think (s)he wanted to bring her here to fight monsters?
Lisa Simpson: Look! It’s J.K. Rowling, author of the Harry Potter books! You’ve turned a generation of kids onto reading.
JK Rowling: Thank you, young muggle.
Lisa: Can you tell me what happens at the end of the series?
Rowling: He grows up and marries you. Is that what you want to hear?
Lisa: Yes…
Phillip Marlowe. We could get drunk together and watch Bogart movies.
Do the characters bring their special features (magic, super powers, phlebotinum-based technology, etc) with them? If so, the characters themselves would be almost trivial compared to the fact that by bringing them here we would be altering the very nature of reality.
The Mick of Time himself, Mike Callahan.
The Luggage.
Igor.
Why Igor?
My husband works in a university library. He’d be tickled pink if I brought The Librarian to life for him!
Duke Crocker. And then I’ll marry him. Lisa, Harry, Duke and I can have a double wedding.
Agatha Heterodyne.
My childhood best friend Josephine March. And Marmee because I need a mother like that even now.
Yep, first thing I thought. Completely irresponsible, but sorta irresistible.
