James "Jimmy" Olsen, Jr. was a bow red-haired young man who works as a cub reporter and photographer for the Daily Planet, alongside Lois Lane and Clark Kent, whom he idolizes as career role models. He also has a strong friendship with Superman.
As Superman's friend, Jimmy has special access to the Man of Steel, thanks to Superman's gift to Jimmy of a "signal watch," a wristwatch which with the press of a button emits a special ultrasonic frequency signal that Superman can hear anywhere on Earth.
