Hamato Xiono was a human male senator from the planet Hosnian Prime who served in the New Republic Senate by around XXX ABY. During this time, his ideals for the direction the burgeoning Republic should take directly clashed with warnings from General Hera Syndulla of the Imperial Grand Admiral Thrawn's return, culminating in a failed attempt to court-martial her for disobeying direct orders. Xiono later became the father, alongside Kazuda's mother, of Kazuda Xiono. During the latter years of the New Republic Era, Senator Xiono facilitated his son's entry into a New Republic Defense Force academy which, in turn, led to Kazuda's service in the New Republic Defense Fleet's Starfighter Corps until he eventually joined the Resistance. When the First Order destroyed Hosnian Prime in 34 ABY, Hamato, Kazuda's mother, and the rest of their family survived, as they had been off-planet during the cataclysm. Following the loss of the New Republic Senate, Senator Xiono contacted his son, warning him of the danger his activity as a Resistance spy had placed his family in.
