It came to me in the shower. Alfred seems like an interesting character and needs more backstory. I would love to write him as an ex agent for Interpol, something like 007 though less of a playboy. Batman, Robin, and the rest of the batty team are injured and it's up to Alfred to dust off his skills and clean up Gotham. Dressed in a black bowler hat, long coat, domino mask, and armed with a black titanium cane, he cleans up the streets in a somewhat posh sort of way.

I would have his fighting style be more reactive. A bad guy rushes him, he makes a few moves of his hands and throws them across his shoulder without creasing his vest. Of course he wouldn't be perfect, age being a factor. More on that later, I have to get to work.
