TV shows would be good.
video games perhaps? but there are only so many - and I'm not much of a gamer so I could only come up with, like 5.
or maybe "fictional supporting characters" from TV, movies and books. like "Boris Grishenko from Golden Eye"
oh, how about "historical figures" - famous and/or obscure people who influenced history, for the better or worse? That could be fun and educational!
