Sev

Sev, also known by the designations RC-1207 and Delta-07, was a clone of Mandalorian bounty hunter Jango Fett. Born in 32 BBY on the watery world of Kamino, Sev was trained by the Mandalorian Cuy'val Dar training sergeant Walon Vau to become a clone commando in the Grand Army of the Republic. Joining with three other commandos to form the elite special forces unit Delta Squad, Sev served as the unit's star sniper. When the Clone Wars broke out between the Galactic Republic and the Confederacy of Independent Systems, Sev took his place in the Grand Army's Special Operations Brigade under Jedi General Arligan Zey and served alongside his clone brothers in Delta Squad on a number of battlefields, ranging from the deserts of Geonosis, the halls of the RAS Prosecutor, and the streets of Coruscant, to snowy Mygeeto and the plains of Haurgab. Known for his morbid sense of humor and a hatred of Geonosians, Sev was an efficient killer and loyal soldier who completed several covert operations within Delta Squad until the squad's fateful mission to Kashyyyk. There, while in the process of destroying a Separatist warship over the Wookiee city of Kachirho, Sev fell under attack, and the other members of Delta Squad were ordered to pull out of the area without him, forced to leave Sev behind. With the rest of his squad unsure whether he was alive or dead, Sev became one of many clone soldiers listed as missing in action.
