Batman:

The real identity of Batman is known by few people, like, his butler Alfred Pennyworth or Robin and Batgirl (his friends in the crime fighting job). It toke
some time for the Gotham City to accept the Bat as their protector, not enemy,
and they did, when people like the Joker and the Penguin started robbing their
banks and doing things beyond crime. His legendary costume is very well known
and famous. Long blue (in some dark blue, almost black) hood with a mask in
a shape of bat's head, blue gloves and blue boots (in some, once again black),
grey costume with the legendary black-and-yellow sign of Batman. He may not have super-powers like the other DC heroes, but he has high-tech "all over him"!
