Charlotte Hepner was a Zeon national who joined the military before the outbreak of One Year War. After graduating from the Zeon army military academy, she was immediately assigned to major Garret Schmitzer's newly formed Midnight Fenrir Corp forces. She initially works as the unit's communications operator, and later on as a reserve mobile suit pilot. Charlotte shows pride in her abilities, and because of this, she shows animosity towards fellow team member Nikki Roberto who was given the role as team leader despite having no combat experience. Following the end of the war, as told in the Gundam Legacy manga, Charlotte is promoted to lieutenant in the new Republic of Zeon army. In U.C. 0084, Charlotte and Nikki help captain Ken Bederstadt prevent renegade Zeon forces from carrying out a nuclear attack. She also reunites with former Midnight Fenrir members Renchef and Sophie Fran.
