A former mayor of New York, Eschonbach still wielded considerable influence within the Earth Federation's political scene. He disapproved of his daughter's relationship with Garma Zabi and forbade her from leaving their residence. Later, he informed Icelina of Garma's death.
In "Mobile Suit Gundam: The Origin", he is the mayor of Los Angeles and a former candidate for President of the United States. He has been supporting the anti-Zeon guerrilla movement behind the scenes, and had them rise up in arms during a party. He was arrested by Zeon military police for treason immediately after informing Icelina of Garma's death, but was executed on the spot for trying to take a pistol from his desk drawer.
