Movie
Description
Alphon operates as an intelligence officer for the Dark Star Cluster Empire during Earth's occupation. He first encounters Yuki Mori wounded after an escape attempt, secures medical aid for her, and subsequently detains her within his personal quarters for observation. Departing from typical Dezarian conduct, he treats her respectfully, providing food and conversation despite her prisoner status.

While Yuki is captive, Alphon develops authentic romantic feelings. He delivers news of Susumu Kodai and other Yamato crew members' apparent deaths during their shuttle hijacking attempt, intensifying her despair. Recognizing her enduring love for Kodai and the impossibility of reciprocation, Alphon chooses to release her. He enables her to join the human resistance, pledging that should they face each other in battle and she triumphs, he will assist her mission to halt the Dezarian invasion.

Alphon reappears during the Earth Resistance's assault on the Dezarian Hyperion Bomb facility. Confronting Yuki directly, he challenges her intent to kill him; her hesitation prevents him from harming her. Mortally wounded by a resistance fighter he had previously shot, Alphon retaliates and kills the soldier before collapsing. As Yuki aids the dying officer, she discovers his concealed cybernetic nature—he is a cyborg. In his final moments, he requests the simple human comfort of warmth through an embrace, which Yuki provides. Dying in her arms, he confesses his love and voices profound melancholy over the existential emptiness plaguing his people since their widespread bionic conversion. Honoring his promise, he supplies Yuki with the Hyperion Bomb blueprints and precise deactivation instructions, enabling the resistance's success. His body's fate remains officially unconfirmed, though presumed buried despite his enemy status.

In the *REBEL 3199* remake continuity, Alphon returns, holding the rank of Major within the Dezarium Army's Intelligence Division during the 2207 Earth occupation, overseeing the Far East region. His mission critically involves locating and capturing "fragments of Iscandar," specifically targeting Sasha Iscandar Kodai and the Yamato to restore lost Iscandarian technology. He infiltrates the Yamato, kidnaps Sasha, and delivers her to the Dezarium AI entity Mother Dezarium. Simultaneously, he holds Yuki Mori prisoner on Earth while his consciousness remotely operates a secondary body aiding Captain Ranbel aboard the pursuing battleship Grodez. During her captivity, Yuki considers assassinating the physically present but mentally absent Alphon, ultimately deciding against it. His role as a potential romantic complication between Yuki and Susumu Kodai is acknowledged within this continuity.
