ARC trooper A-201 (batch Alpha-0) aka "Trauma". One of the original ARCs trained by Jango Fett, A-201 took the name "Trauma" after a series of particulaly disturbing incidents while still undergoing training on Kamino. A-200 and A-201 were two of twelve in their batch (Alpha-0). A horrific accident involving LAAT-i drops under live-fire went bad. The craft they were on crashed, killing all but units A-200 and A-201.
Several months later, A-200 and A-201 (batch Alpha-0) were in the gun range, undergoing hands-on training with a variety of alien weaponry at the age of 8 actual years (16 accelerated). The Kaminoan Quality Control Supervisor in charge of their batch had concerns regarding A-200's performance since the crash. She decided that A-200 wasn't meeting quality control standards and that he had to be "reconditioned". While the pair were gearing up with Wookie bowcasters, the Quality Control Supervisor and her Product Removal Technichians arrived to "recondition" ARC A-200 (batch Alpha-0). Knowing full well what "reconditioning" meant, A-200 simply pointed his bowcaster at the Kaminoan and calmy blew her head off. He then took his own life before his brother could stop him, splattering gore onto A-201's armor.
A-201 took to calling himself "Trauma", and painted his armor with a facsimile of the blood splatter from his brother, as a way to honor him. He doesn't utilize the pauldron or rangefinfer common to most ARCs, only his kama and sidearm holsters (and horrific paint scheme) outwardly mark him as an ARC. It is widely believed that Trauma went rogue shortly after Order 66 and may have fled to Mandalore. At last count, Trauma utilized a customized DC-17 sniper blaster, and large vibroblade and a pair of DST-RO pulse pistols. He was known to carry an assortment of grenades and explosives charges.
