The First, and greatest Superhero ever to leap from the pages of a comic strip to the Pop Culture scene.  Born on a distant world, far from our own, Kal-El of Krypton, came to earth as an orphaned child. IInspite of being imbued with powers and abilties beyond those of mortal men by the rays of Earth's yellow sun, Kal-El would work to instill the values of Truth and Justice, and most of all, Hope, taught to him by his adoptive parents, in the people of Earth while also working to defend and protect the weak and oppressed from those who would step on them like ants. Superman's optimistic, hopeful and ofter naive personality puts him at odds with Batman's more serious and cynical attitude, and who's methods Superman disagrees with. 

However, over time,  and despite their differences, The Man Of Steel and The Dark Knight come to respect and trust one another, working together various times to save innocents from the forces of evil.

Played by Tim Daly in Superman: The Animated Series and by George Newbern in Justice League and Justice League Unlimited, the direction I'm going for Superman, even though it's not a big role for the character in this story, is a combo of the best things Tim Daly and George Newbern brought to this iconic character in this take on the DC Universe.
