this list doesn't include heroes who already have public identities like superman, ironman or aquaman also some of the reasons are repeated.

5) Blue Marvel

Honestly, what are they going to do?

4) Sentry

Honestly, what are they going to do?

3) Kyle Rayner

Kyle Rayner usually operates in space and spends little time on earth. His identity means nothing in space since all his villains know his identity anyways. Now on earth criminals would have no way of telling when he would or would not be home is planning an attack would be nearly impossible and like I said before he doesn’t have any enemy’s wouldn’t already know his identity so nobody would immediately want to attack him aside from petty crooks who would fail.

2) Hal Jordan

1) Batman

Bruce Wayne is rich enough to buy protection during events when he would be out in public and his ninja training would have taught him how to spot an assianation attempt he would likely know is coming. He could also use his wealth to upgrade his defenses in Wayne manner in case there was an attack. In addition, it would help his public image with non-dirty cops and criminals.

Of course, criminals would go after him but he would probably be ready for it. Oliver Queen and Tony Stark reviled their identities and like Bruce Wayne they are rich, if they can do it so can he. Lastly, some of his investors would be willing to make some of his gadgets and body armor. Now if they did they would want to mass produce it and sell it to the cops or the army and Bruce Wayne wouldn’t want that for stuff that could be used as a weapons to harm or kill human beings, but for some of his body armor or gadgets he might willing to sell.
