Feldt Grace is a character in Gundam 00 who is a Tactical Operator and mechanic onboard Ptolemy of Celestial Being. She is the daughter of Ruido Resonance and Marlene Vlady.
In season 1, despite her age, Feldt was noticeable as being a fully developed attractive 14 year old dressed up in a skintight outfit that appears reminiscent of an old school female Super Robot pilot.
