Akihiko Hiyama

Akihiko Hiyama (アキヒコ・ヒヤマ, Akihiko Hiyama) was a Delaz Fleet mobile suit pilot during Operation Stardust. As a member of the Zeon remnant forces, Hiyama represented the veterans who remained committed to Zeon’s cause four years after the One Year War.

Biography

Hiyama’s service with the Delaz Fleet charts a veteran pilot who helped execute Operation Stardust long after the Principality’s collapse.

Service with the Delaz Fleet

Hiyama flew with the Delaz Fleet during its exile in the shoal zones, conducting reconnaissance patrols and rehearsing anti-Federation strikes under Aiguille Delaz’s direction. His experience from the One Year War helped maintain discipline amongst less seasoned recruits.

Operation Stardust

When Operation Stardust commenced, Hiyama deployed alongside fellow veterans to cover Anavel Gato’s offensive. The Delaz Fleet relied on coordinated sorties from pilots like Hiyama to harry the Federation’s mobile suit teams and buy time for the colony drop plan.

Final engagement

Hiyama was killed during the fleet actions surrounding Konpei Island, one of many Delaz pilots who fell while trying to deliver Delaz’s “Garden of Thorns” strategy. His death underscores the heavy toll exacted on Zeon diehards who refused to surrender.

Physical appearance

Delaz Fleet personnel records describe Hiyama in a dark Zeon normal suit with a standard green helmet, matching the remnant force’s refurbished combat gear. Brief debriefing footage notes close-cropped brown hair and a hardened expression befitting a career soldier.

Personality & traits

Accounts from fellow Delaz Fleet pilots frame Hiyama as an unwavering loyalist to Zeon’s ideology. His decision to remain in the field despite the Principality’s collapse reflects the remnant cadre’s mix of pride, stubbornness, and camaraderie.

Skills & abilities

Hiyama’s operational strengths lay in the Delaz Fleet’s shoal-zone tactics, where pilots relied on formation flying and debris-field concealment.

Hiyama was a seasoned mobile suit operator capable of executing formation tactics and close-support missions in debris-filled shoal zones. His survival through years of raids suggests sharp situational awareness and adaptability with multiple Zeon frame types.

Relationships

Hiyama’s closest ties aligned with the Delaz Fleet leadership directing Operation Stardust.

Aiguille Delaz

Hiyama bought into Delaz’s rhetoric and served as part of the core cadre that enforced the admiral’s strategic doctrine across the fleet.

Anavel Gato

Hiyama’s sorties supported Gato’s high-profile assignments, reinforcing the ace’s role as the spearhead of Operation Stardust.

Military career

Operating under Admiral Delaz’s command structure, Hiyama specialised in escorting high-value assets, screening the RX-78GP02A Gundam Physalis during its return to orbit, and providing harassment fire against Earth Federation Forces patrols. His experience in the shoal zones made him adept at ambush tactics and flying in coordinated squadrons, giving the Delaz Fleet a veteran backbone during Operation Stardust.

Mecha

Delaz Fleet deployment rosters list Hiyama among the pilots rotating through refurbished MS-14A Gelgoog and MS-09R Rick Dom units, the mainstay mobile suits maintained by the remnant forces.
