Green Lantern Vs. Doctor Doom

Alan Scott has always been a favorite character of mine.  I like that he has a power ring, but is separate from the Green Lantern Corps.  I always liked that he ran a radio station and called Gotham his home.  But the main reason I really like him is that he is the one hero that I can think of that is a confirmed southpaw!  As a left handed kid growing up, I definitely took note of which hand he wore his ring on.  Are there any other characters that have been established as being left handed?
