For Er

You are not a real Batman fan clearly others have been Batman if you have read the comics

Jean-Paul Valley/Azrael - was asked by Bruce to assume the role after Bane had broken his back (Knightfall arc)

Dick Grayson - asked by Bruce after stripping Azrael of the mantle (because he was ****ing up), while Bruce still needed to train after recovering from Bane's attack. (Prodigal Son arc); Dick is also the current Batman after Bruce's apparent death (apparent, being the operative word).

There are some Silver Age/pre-Crisis stories where Thomas Wayne acted as a Bat-Man when he was comparably Bruce's age. Along those lines, I believe there a story where Alfred dresses up as Batman to perpetuate Bruce's secret identity.

There might be some other stuff, depending on how technical you want to get (or if I'm just entirely absent-minded on something), both those first two names are the biggies.

Im only a recent Batman comic fan, mostly a Batman movie fan though. Stop making gay speeches and acting like you know everything.
