Kish served as a corporal within the ranks of the Alliance Military. He took part in the Battle of Hoth, but after the retreat, he was among the Alliance members who were not evacuated. Corellia was the homeworld of his family.
Kish's initial appearance was in the "Return to Hoth" campaign of the Legends of the Alliance companion app for Star Wars: Imperial Assault. The outcome for Kish is not fixed; it is determined by the player's choices and performance throughout the various missions. He could perish on Hoth, or he could survive the ordeal and reach Haven alongside Myra Talcon and the squad.
