The current Reaper mask design
The Reaper mask is the mask worn by Gabriel Reyes, under his "Reaper" persona.
The mask is a specialized breathing apparatus that resembles a white jack-o-lantern with narrowed red eye slits. Its breathing mechanisms aside, the mask is also worn by Reyes in part to protect his identity, since he wants the world to believe him to be dead.
The mask connects to Reyes's armor, and has a comms. system, which can receive audio feeds, and amplify Reyes's own voice (his sinister laugh is a case in point). It is apparently customizable, able to have functions such as a HUD, a gas filter, and an omnidirectional comms system connected to a GPS.[1]
