Jerid is a member of the Earth Federation's counter-insurgent organization, the Titans, as well as the arch nemesis and rival of Kamille Biden. The Titan's original intention was to defend the Earth Federation against supporters of the former Principality of Zeon, as well as to investigate Zeon sympathizers. However, they eventually turned rogue, allying themselves with Axis Zeon in order to fight against the Anti-Earth Union Group in an attempt to gain control over the Earth Sphere.
