Hell Knight (Doom 3

Otherwise known as the "Brick Shit House", the Hell-Knight is an irritating enemy that one will encounter most often in the game's 'Hell' segment (every other room). The BSH's main attack is to throw a ball of what is presumabley plasma, much like the Imp, which does significant damage and seems to have a slight area of effect to it, with damage delivered scaling down the farther one is from the blast. Alternatively, the BSH can deliver a punishing melee attack. Also, it's worth noting that the lovable "Brick Shit House" has an uncanny resistance to rockets.
