There was a Japantown in San Francisco, but after the internment camps that locked up all the Japanese, Japantown shrunk down to just a couple tourist blocks.
I'm a huge, huge lover of weaponry, of Japanese martial arts movies.
When my editor sent me the first two images of Joker's daughter, I was struck by how confident she looked despite her boney appearance and horribly scarred face. So I starting thinking, how did Duela gain such confidence in a world that prizes beauty?
There are a lot of writers who just want to do their own thing and avoid the rest of the Marvel Universe. But for me that was one of the things I loved about Marvel: that shared universe. So of course you would run into a mutant in Manhattan. You would run into another hero in Manhattan. For me, I figured why not? Why not have that fun?
There is an unspoken feminist layer to Katana. She's an aggressive modern woman with traditional Japanese roots. She was in love with her sword because she believed it contained her husband.
When I read Katana's run in 'Birds of Prey,' I was curious about her restraint. She didn't laugh, didn't loosen up, didn't seem to have a light side. I thought, well, that demure nature is what we believe of women of Old Japan, so she seemed not like a modern Japanese but from an earlier time.
