Nick Cage names son Kal-el

[Dupes]

I heard about this on Howard Stern this morning. I hear his last name really isn't Cage either, I hear that's his stage name. Apparently Cage is the name of some sort of comic book hero that was the first African American hero apparently. He used this comic book hero's name as his stage name. I don't know if this is true or not, but that's what I heard on Stern. Anyone know anything about this?
