Jimmy Olsen is an investigative reporter and photographer for the Daily Planet. He regularly interacts with his co-workers Clark Kent, Lois Lane and editor Perry White. Jimmy often accompanies Clark or Lois, taking photos as they gather information for the Daily Planet. Jimmy is also best known as being a personal friend to Superman, even possessing a signal watch that could call for help at any time.
Although Jimmy is just a regular human and possesses no natural powers of his own, he occasionally finds himself in situations where he develops bizarre transformations or mutations, giving him wierd special abilities. The powers are always temporary, however, and Jimmy never becomes a fully-fledged superhero.
