    Probably because few Japanese know about the myth of Prometheus. When you are trying to come up with a title, you want something that will stand out. Things in foreign languages/cultures are good at that. They stand out, and we generally think it is cooler. What would you rather hear a character say? "Kamehameha" or "Turtle Destruction Wave"?

    However there is one exception to that, you also want to use something that your audience at least partially understands. We judge books/movies by their cover and their title, so you want the audience to be able to relate at least somewhat to the title.

    Because of western media, and Japan's own past with Christianity, a decent bit of the population know at least some of the names of biblical figures, even if they don't know the story behind them.
