Not much is known about Karla Sofen as she is doesn’t frequent the Marvel universe often. Apart from the regular superhero powers, Karla is particularly skilled in using hypnosis. Like her predecessor, Doctor Faustus, Moonstone has perfect pitch and modulation in her voice, and was even able to use these talents to cause General Thaddeus “Thunderbolt” Ross(Red Hulk) to suffer a complete nervous breakdown.
