Hell Knight/Doom 3

The Hell Knight in Doom 3 is very muscular and heavy. An in-game examination of their spine indicates they have massive skeletons as well. They have no visible eyes, ears or nose. Their attacks are very similar to the Imp: melee attacks (including biting) and aquamarine fireballs with splash damage. When facing one of them, it is strongly recommended to use the Soul Cube or the BFG, for they can absorb large amounts of damage.
