Exedore Folmo served as Chief Archivist for the Zentraedi forces. His exceptional memory capacity surpassed any electronic device, enabling him to maintain detailed records of Zentraedi combat history for instant recall. Cloned via the Zentraedi Clone Synthesis System, he was assigned as advisor to Commander Vrlitwhai Kridanik aboard the Nupetiet-Vergnitzs-class Fleet Command Battleship. Tracking a Supervision Army cruiser's fold signature, they arrived in Earth orbit on February 7, 2009, coinciding with the planned relaunch of the ship later designated SDF-1 Macross. Exedore analyzed human tactics and technology during initial engagements, noting the unexpected effectiveness of reaction weapons and the unpredictability of strategies like the SDF-1's space fold maneuver.
Throughout Space War I, Exedore demonstrated a growing fascination with human culture, significantly influenced by singer Lynn Minmay. He witnessed widespread Zentraedi defections caused by cultural contamination from Micronian society. Following Commander Vrlitwhai's decision to cease hostilities, Exedore underwent micloning to participate in ceasefire negotiations. During these talks, he performed Minmay's song "My Boyfriend is a Pilot" and facilitated her involvement in the diplomatic process. He later provided critical intelligence and tactical planning to defeat the forces of Supreme Commander Golg Boddole Zer.
After the war, Exedore remained micronized to assist with Zentraedi assimilation into human society and Earth's reconstruction. During this period, fearing intellectual degradation from prolonged micloning, he underwent genetic modification and physical alteration to enlarge his brain capacity. This process transformed his appearance significantly, replacing his original purple hair with a distinctive bulbous cranium.
By 2045, Exedore joined Captain Maximilian Jenius aboard the Battle 7 as an advisor during the Macross 7 mission. His expertise proved invaluable against new threats like the Protodeviln, though he initially struggled with instinctive terror upon encountering them. Typically appearing at full Zentraedi size on the ship, his head protruded through specially designed bridge floor openings near the captain's station. He occasionally left the ship for field missions, including investigations of Protoculture ruins and scientific conferences aboard vessels like the Einstein.
In 2068, Exedore continued serving alongside Jenius on the Macross Gigasion, maintaining his advisory position and distinctive bridge presence. During conflicts like the battle against Heimdall, he relayed strategic information and orders from Lady M through a genetic link to her Zentraedi advisor. His legacy extended beyond military service through cultural references such as the "Folmo" shopping mall for macronized Zentraedi on the Macross Frontier colony, named in his honor.
