An officer of the Earth Federation Forces who took over command of the warship Diva for himself by forging military credentials and subduing its captain after learning that their orders were to abandon Nora's inhabitants to UE's mercy. Despite helping evacuate the colonists to safety, Grodek has a prison warrant on him due to his insubordination, a fact he hides from his crew mates. His true intentions are to make use of Diva and the Gundam to attack the UE's base in vengeance for his wife and daughter's deaths during "The day the Angel Fell". After the fall of Ambat, Grodek took the responsibility for his and his comrades' insubordination and was sentenced to prison.
