Judau Ashta was a teenage boy living in the Side 1 colony of Shangri-La, working as a junk dealer alongside his friends in order to provide a better life for his sister Leina. One day he met a man named Yazan Gable, who roped him and his friends into helping him attack a certain ship that had docked in Shangri-La.
That ship turned out to be the AEUG battleship Argama, under the command of the legendary Bright Noa. It wasn’t long before Judau met the AEUG Gundam pilot Kamille Bidan, left in a catatonic state after the final battle of the Gryps Conflict, and found out that Yazan was actually a surviving member of the infamous Titans that had been wiped out at the end of the conflict.
Judau helped the Argama drive off Yazan several times, but an even greater threat was emerging to wage war against the weakened Federation – Neo Zeon. With Kamille still out of commission, Bright had no choice but to recruit Judau and his friends into the AEUG.
And thus, Judau Ashta would become a legend as he fought against the Neo Zeon forces in what would be known as the Second Zeon War.
