RC-1140 "Fixer"

Of all the members of Delta Squad, Fixer possessed the most pronounced qualities of a simple clone trooper. He always spoke to the point and was always ready to obey orders. However, he also shared some of the distinctive traits of the squad itself—the elite among all commandos. Fixer preferred fighting on the battlefield (that's what they were trained for), and he knew his own worth and his skills, as well as that of his brothers. Incidentally, it's unknown whether he truly considered Boss, Scorch, and Sev brothers. Four-Zero almost never called each of them by name, limiting himself to their numerical callsigns. However, there were very rare moments when Fixer might show any emotion—for example, dissatisfaction or simply a desire to speak out. This suggests that, while Boss's second-in-command resembled a standard clone trooper, he was still more independent—like all commandos. Fixer was familiar with technology and could hack any computer terminal with ease. He was an ace at it, and this also set him apart from his brothers. Perhaps the computer analogy lies elsewhere—it was as if the commando himself were a computer, if one can make such a comparison. Four-Zero was also known to favor a retractable vibroblade, which he often demonstrated in combat. However, Fixer never fought with relish or rage; all that can be attributed to him was a slight nervousness, a normal characteristic of any soldier. The standard DC-17m blaster is also Fixer's usual weapon. Forty's armor is covered in dark green stripes, and his chest plate bears two circles of the same color.

He fears only his teacher, Walon Vau.
