Demon

Commonly referred to as "Pinkies" or "Bull Demons", Doom's Demon is a big, bulky, vaguely humanoid demon. Demons do not have ranged attacks, so they are no threat at long range. However, Demons have a huge advantage over other hellspawn with ranged attacks: speed. Faster than any other monster in the original Doom (and outmatched only by Doom II's Arch-Vile), the Demon closes distances very quickly, often running towards the player in a zig-zag pattern, making them harder to hit.

In the original Doom, Demons were usually found alone or in small numbers, but in Doom II they were often found in larger packs, making them all the more dangerous to deal with.

The preferred weapon against Demons for many Doom players is the chainsaw, due to the monster's lack of distance attacks as well as its relatively high pain chance, and because of the weapon's lack of ammunition.

If a demon is nearby, the game will play the sound effect DSDMACT.
