Jimmy Olsen

James Bartholomew Olsen, also known as Jimmy Olsen, is a character from the DC comics.

Jimmy is a Photojournalist working at the Daily Planet, and a close Friend, of both Clark Kent and Lois Lane.

Personality
Most of Jimmy's incarnations are kind and friendly. He is also arguably Superman's most loyal supporter, cemented by the  Truth  storyline.

Abilities
Jimmy has no exceptional personal powers or abilities when he has not been transformed by various circumstances into a superpowered being. When he has been transformed, he gains powers appropriate to this new form, however these are always temporary and cease to work when he has been transformed back to his normal human self.

He carries a signal watch which he can use to alert Superman to his need for assistance. Recently it has been suggested that the watch no longer functions for this purpose, but he continues to wear the watch for appearance's sake.
