Proclaimed as a "master of war", Kotin Jax was considered to have been the most exceptional warrior of his era, although it was unknown if he had at one point held the position of High Protector. Although little was revealed about him, Kotin Jax was considered most famous for being the Prime that led the Echani people into the Preliator Wars―the long conflict waged between the Echani tribes and Mandalorian clans―and leading the Echani to a number of significant victories. As a result of his extraordinary battle prowess, Kotin Jax was bestowed with the title of Zokivinhus Prime.
