He began his life as a vat-grown soldier on Kamino, a genetic duplicate of the legendary Jango Fett. A less-restricted variant than standard clone troopers, Alpha-28 was an Advance Recon Commando, or ARC, an elite group. He and his brothers were personally trained by Jango Fett himself to become one-man-armies, capable of completing a wide variety of missions independently or with support.
