Star Sapphire - Carol Ferris

Representing the planet Earth for the power of love, it's Hal Jordan's girlfriend, Carol Ferris, AKA Star Sapphire!  This iteration of Star Sapphire is heroic despite her villainous reputation in the pre New 52 comics.  She and Hal Jordan are deeply in love with one another, to the point where she has nicknames for him.  She also is a late coming member of the Justice League.  For Star Sapphire's costume, it's a mix of her look from Green Lantern The Animated Series and her appearance from Justice League: Doom.
