Alfred Pennyworth (Full name: Alfred Thaddeus Crane Pennyworth) is a character in Batman: Arkham Origins

Alfred is Bruce Wayne's loyal butler.

Alfred knows that Bruce Wayne is Batman, and aids him.

You can generally find Alfred in the Batcave.

Alfred claims to have been an accomplished actor before he signed on to be the Wayne family butler, but records hint at a history with military intelligence. Being an actor could have been a cover, or acting could just be a very useful skill for an intelligence officer to have. For Alfred's part, he's not offering up details, but his extensive medical knowledge suggests he's more than a common thespian. Alfred is still having trouble accepting the reality of Bruce Wayne's double life and continues to push Bruce to give up his crusade for more mundane pursuits.
