Vulgar

The Vulgar is amonster encountered in Doom 3:Resurrection of Evil. It resembles an Imp although there are some bodily differences. The Vulgar have only two eyes that have an orange glow. They are slightly shorter and have a monkey-like frame instead of human. Due to this, they move on all four legs but will sometimes stand up on their hind legs when angered. Unlike the Imp, they support a long tail, their bellies have small insect-like limbs attached to them and their lower jaw is designed like an insect's mouth parts. They also differ from the imp because they have plasmaballs instead of fireballs. Their plasmaball attack is comparable to the Hell Knight's version, though it is significantly weaker - even weaker than the imp's fireball. The Vulgar's plasmaball is unique to any other attack in the whole of Doom 3 in the way that it reaches the player. Instead of it being projected straight towards the marine, it "archs" or "dips". This makes it harder for the player to anticipate the splash location of the plasmaball and therefore makes up for the Vulgar's rather puny physique. The other attacks consist of leaps and claw slashing. They have a mechanical-like growl that they emit in each attack and are capable of crawling on walls and other surfaces. Also, unlike other monsters, its spawning cloud is cyan rather than orange.

The Vulgar was originally planned to appear in Doom 3. It was stated to be the Arch-Vile, but was scrapped and its appearance was saved for the expansion pack.
