Christo was a Quarren male who served as a senator of the Galactic Republic during the Clone Wars. Loyal to the constituents who had appointed him to the Senate, Christo placed their needs before those of all others during his career, even the clone troopers who had been bred to fight for the Grand Army of the Republic. In 21 BBY, when Senator Halle Burtoni proposed a drastic increase in clone trooper production, Christo initially considered voting for the bill, especially after several opponents to the measure were pressured into supporting it by bounty hunters. However, he rethought his position following an impassioned Senatorial address from Senator Padmé Amidala.
