Cyberdemon (Doom 2016)

The cyberdemon returns in the 2016 reboot of Doom. It was the first monster to be revealed by id Software in publisher Bethesda's E3 2014 showcase, in the form of a one minute video of the monster powering up for battle while shrouded in smoke and shadows. Its identity as the cyberdemon was later confirmed after the E3 2015 public reveal, though Doom community members widely speculated this identity correctly beforehand, based on the monster's size, shape, and some sound design similarities to the same monster in Doom 3.

Appearance
The cyberdemon appears as a tan-colored, towering cybernetic demon with two antler-like horns, four small oval orange eyes set in two far-apart groups on its face, and a mouth full of sharp teeth constantly clenched into an evil grimace similar to the one displayed by the original cyberdemon. Like its classic incarnation, its left arm and right leg are replaced to different degrees with cybernetic prosthetics, the former being replaced with what appears to be a powerful energy-based weapon. Various other parts of the creature also appear to fuse human technology with demon flesh, including a plate embedded into the creature's chest which glows with blue light. When the monster roars, sparks of fire stream from its mouth.

E3 2015 reveal
In the E3 2015 reveal, the cyberdemon appears at the very end of the video in an after-credits stinger sequence, dropping or teleporting in unexpectedly behind the player as she moves into a narrow corridor. The cyberdemon is seen to begin leveling its massive arm cannon at the player and charging up for a shot, as the player brings out the BFG in response and begins likewise charging it up. A 4K resolution screenshot released after the conference showed the cyberdemon in the midst of a melee with other monsters somewhere in Hell, leading to speculation that it may be a recurring major enemy rather than a boss.
