I know the dark hair Power Girl here is an EVIL clone of PG but I like the hair. So assuming PG is a "natural" blonde and the evil clone hair is either dyed or a genetic change to the clone. Which one do you like more and do you think PG should dye her hair black in the comics once in a while?
Remember, her disguise as Karen Starr, SOEMTIMES she wears a wig and sometimes she does not!!
