Carl (Broken Steel)

 is a new character who is added to Fallout 3 in the add-on Broken Steel.

He was a member of a group of ghouls who tried to make themselves a place to live in Old Olney Underground, assuming it would be an ideal place for ghouls to settle down since nobody ever goes there. The group set about knocking down some walls and apparently disturbed a group of Deathclaws. At the time the Lone Wanderer arrives, Carl is already dead.

From the looks of it, it looks like Carl was the doctor of this new ghoul settlement due to his outfit, plus, he's found dead not to far from the demolished hospital.

Appearances
Carl appears only in the Fallout 3 add-on Broken Steel.
