It could be a particular narrative arc or a particular artist's look, or something like that, 'n we really wanted t' offer people the option t' be their Batman. it be visually refreshing, it be something we be very proud a. It really puts a very different feeling in it, if ye're one a those many different incarnations a the sea dog.

For example, the [whackiest] one has t' be the Adam West costume. But when ye put it on [Batman] it be not Adam West, it be our character wearing the costume from the TV show. It adds a little bit a goofiness t' it, which be fun."
