Jothan Tiaan Jerjerrod, more widely known as Jo Jerjerrod, was a male human who fought for the Resistance Starfighter Corps. During their conflict against the First Order, he commanded his own squadron. Notably, Jo was the grandson of Imperial Moff Tiaan Jerjerrod, who met his end on the second Death Star.
Born on the planet of Tinnel IV was Jothan Tiaan Jerjerrod. During his younger years on Tinnel IV, he crossed paths with the Boddee family, a Gungan family that hailed from Naboo. Najeema Boddee, the youngest of the family, and Jothan would eventually develop a long-lasting friendship.
Jerjerrod later became a member of the Resistance as a cadet and quickly became recognized as one of the most dedicated members of the Resistance. Jerjerrod was descended from a line of steadfast warriors, given that both of Jerjerrod's parents were officers in the First Order, a fascist military junta located in the Unknown Regions of the galaxy that arose from the downfall of the Galactic Empire, which the Resistance had pledged to oppose. After hearing his parents' discussions, Jerjerrod quickly came to the conclusion that he disagreed with their beliefs and that, in his view, they would not improve the galaxy. He then vowed to defeat the First Order and joined the Resistance by feigning enlistment in the New Republic Military Academy on Ganthel. The academy's commander, who sympathized with the Resistance's goals, agreed to provide cover for Jerjerrod. General Leia Organa and Admiral Gial Ackbar were aware of the arrangement and permitted him to communicate with his parents in order to maintain the facade.
Due to his persistent efforts, Jerjerrod was eventually given command of J-Squadron, a squadron composed primarily of new recruits within the Resistance.
Jo Jerjerrod was known for his serious demeanor and strong aversion to the First Order, whose principles he believed were detrimental to the galaxy. Because of this, he fully committed himself to his training with the Resistance and had little patience for cadets who did not appear to take their training seriously. Jerjerrod tended to be reserved and did not readily confide in others, but he deeply valued those who had demonstrated their loyalty to him.
