Nightwing

There once was a hero named Dick, With a body so supple and quick, He flew throught the air, With great savior faire, But his mentor's as thick as a brick!

Oracle

There once was a hacker named Babs, On everything her 'puter keeps tabs, She's one mean Bird Of Prey, On any one given day, Many a baddie she nabs!

Tim(Robin)Drake

Once a young hero named Robin, Was forever and constantly sobbin', He's always so sad, 'Cause he misses his Dad, Still he's got female hearts all a throbbin'!
