Not many people anymore know about the greatest Supergirl of New Earth, Matrix. She could shapeshift, turn invisible,was the Earthborn Angel of Fire, married Lex Luthor, was from another universe, had all of Supermans powers, was Metropolaces protector after Superman was killed by Doomsday, as well as being a mentor to Superboy. DC got rid of her claiming she was too similar to Superboy! She was very different and the most unusual and exciting Supergirl. DC should reintroduce her as Superwoman in a limited series.
