super heroes and their alter egos...

Super heroes and their secret identities are oftenconsidered alter ego.

Superman assumes the identity of the mill mannered newspaperreporter ‘Clark Kent’ in order to live among the citizens of Metropolis without arousing suspicion. Where as Clarks true self is in fact Superman.

Batman is a character created by Bruce Wayne, order todisguise him for the purpose of fighting crime. Batman comics and movies, such as batman begins have explored the themeof the true self (Wayne) becoming lost or giving himself over to the alter egothat if batman. Much like the plot of Dr Jekyll and Mr Hyde.

Superman becomes the person that Clark Kent adopts in orderto freely use his gift to hep the world with out jeopardizing his family andfriends. Controversially, carefree playboy billionaire Bruce Wayne becomes thealter ego necessary to hide the true person of the crime-fighting batman.

The incredible hulk comic book series and movies furthercomplicates this theme as Bruce Banner loses control to the Hyde-like-hulkwhenever he becomes angry, yet he also depends on the hulks super powers inorder to combat villains. 

Comic book inspired alter egos can be seen in other forms ofpopular fiction, including television, and movies adaptations of comic books,parodies of genre and unrelated fictions such as star wars and angel.
