Angel was definitely not an angel. Angel had a black Mask that had a sideways 8 with the holes of the 8 being where the eyes could see, a white filling in of the rest of the 8.

Angel had a SIG 556, SOCOM Mk20 SSR, D50, along with a Sniper Turret and Artificer Hive, as well as an EMP system. Angel also had a Crash Axe for close combat, wearing all black clothed and armor, the only thing mildly black being the rest of the Mask that didn't have a white filling.
