Jojo (real name Joseph Willard Fotheringay) is a former solider and skilled engineer, who has also been known to work as a professional assassin and bounty hunter.
First Galactic War
After the war, Jojo moved to Hope City on Planet Leto, though he did remain in close contact with the rebellion. Along with the Ashanti Okar, he was one of the lieutenants serving under Colonel Michael Kane in the Veterans group. He also became pretty good friends with John Pilgrim, a retired starship captain.
He met John's daughter Gail Pilgrim and her crew when she came to Planet Leto in search of her father. Using a pulse amplifier and a signal disruptor, Jojo was able to build a device which enabled her to break the Colonel out a Strata jail.
After Gail helped the Veterans fulfill their objectives in the city, he and Ashanti accompanied her on a voyage to Dusk Island Mines, where they found John Pilgrim.
Unfortunately, they were all arrested shortly afterwards by a J.A.C. team who had been pursuing Gail across the galaxy.
Prison Station 13
Along with Gail's other comrades, Jojo was incarcerated at the infamous Prison Station 13, also known as "The Chain." He and Ashanti were charged with various terrorist acts associated with the Veterans group.
Two months later, he was directly involved in a prison break orchestrated by Sabina White, and he was finally able to rejoin the rebellion.
