Arch-vile (Doom 3)

The Arch-Vile in Doom 3 is a large, off-white coloured humanoid demon, capable of summoning many of the non-boss demons (though Imps & zombie commandos are more common). It can also slash its victims at close range, as well as raise a wall of fire that can seriously hurt the player, causing up to 20 points of damage. In some special cases, it is capable of making the ground erupt in flames underneath the player similarly to its original attack, but this time, it's possible to dodge it, although it requires that players are on the move constantly.

As with its previous Doom incarnations, the Arch-Vile can be easily underestimated. Though possessing less than half the hit points of the Hell Knight, the Arch-Vile's varied attacks & ability to summon other demons make it one of the tougher enemies to defeat for it will instantly summon demons after its appearance (most commonly, far away from the player's position). Many players feel the Arch-Vile needs to be killed as soon as possible, often with the Soul Cube or BFG. Rockets are good too.
