Reaper is a supersoldier created by SIN. He follows orders closely and shows an impressive ability to think quickly in the heat of battle. He has never been known to show any kind of emotions, even while not wearing his cold Mandalorian helmet. He was made using Taung DNA, preserved in a corpse found on Dxun. SIN was successfully able to create Reaper using a mix of both Taung and Human DNA. His physical features represent that of a normal human, except for his slightly gray skin.
