Merda Ditz (メルダ・ディッツ), also known as Melda, Garmillas Second Lieutenant and ace fighter pilot of the 707th Air Squadron in Space Battleship Yamato 2199. Daughter of Admiral Gul Ditz, Supreme Commander of the Garmillas Astro Fleet. Earth-equivalent age of 19 during the 2199 campaign.

Proud member of a long-standing military family; she values honor above all and flies a customized red Czvarke (Tsvuelke). First major Garmillas officer to make direct contact with the Yamato crew after both ships become trapped in a dimensional fault. Serves as liaison (and temporary hostage), develops a tense-but-respectful relationship with Yamamoto Akira, and later aids in freeing her father from political imprisonment on Leptapoda before remaining aboard Yamato as a formal liaison. Canon portrayal from the 2199 remake series: composed, honorable, and professional, with occasional glimpses of youthful curiosity.
