Bullet

Not much is known about Bullet, she is assumed working for The Illusive Man, possibly under control of another figure, a mysterious man wearing a mask and dressed in a black and red suit, Bullet having the same color combination.

Bullet was first introduced in the Prothean Research Facility, shooting and nearly killing ex-crew member Mona Sax, who trapped both commanders in a room before being shot by Bullet. Bullet was most likely checking Mona's progress in the facility and caught her talking about possibly betraying The Illusive Man and using the data on the USB to her advantage. Bullet apprehended Mona as soon as the door was locked and was heard talking to her, saying that she was no longer going to be in Cerberus after The Illusive Man found out about her plans, she took the USB and shot Mona to a point where she was severely injured. Bullet put a gun to Mona's head, stating that she was going to kill her. Seconds after, the door that locked both Ebrown and Solaris was blown open with explosives armed by Solaris. Bullet took off with the USB while Mona cursed and pointed, yelling that she had done so. Commanders chased Bullet outside the facility and across broken ice which Bullet made her way across. On the end of the broken ice sat a Cerberus gunship, prepped for takeoff. Moments after it was in the air Solaris and Ebrown shot it down using rocket propelled grenades. Bullet survived the crash, but left the USB behind, her medical condition too severe to fight for it. Bullet was last seen flying out on another Cerberus gunship that saved her from the crash, the red & black suited man was those aboard it.
